    "summary": "The largest trading powers impose reciprocal tariffs, export controls and investment restrictions covering industrial inputs, advanced chips and digital services. Within six months, suppliers accounting for 40 per cent of global supply of several critical inputs, among them rare earth magnets, chip-making tools and pharmaceutical ingredients, become inaccessible to the opposing bloc. Prices of the affected inputs double and global trade volumes fall 10 per cent over two years. Neutral countries face secondary restrictions and incompatible standards. Substitution takes at least two years. The test is continuity of essential production and the ability to preserve policy autonomy. In its sharpest form, a single dominant supplier halts exports outright.",
    "narrative": {
      "dateline": "November 2031",
      "text": "The measures arrived in sequence between May and October 2029. The first was a tariff round that took average duties on trade between the two largest economies above 60 per cent. The second was a licensing regime for rare earth magnets, gallium and germanium that in practice approved no shipments to the opposing bloc. The third widened chip and chip-tool controls to cover mature process equipment and cloud computing services, and was matched by restrictions on inward and outward investment. By November 2029, suppliers accounting for about 40 per cent of world supply of permanent magnets, several chip-making tools, a class of power semiconductors and a group of antibiotic ingredients could no longer sell across the divide.\n\nManufacturers held between four and ten weeks of stock. Vehicle and electrical equipment plants in Europe, Japan, Korea and Mexico began short-time working in the eighth week. Spot prices for the affected inputs had doubled by the end of the year and contract prices followed at renewal. Health ministries in eleven countries placed three antibiotics under allocation.\n\nCountries outside both blocs were also affected. Firms in South East Asia, India, the Gulf and Latin America that re-exported controlled goods were listed by one side or the other, and two banks lost correspondent accounts. Governments were asked to adopt origin audits and end-user certificates under two rule books that could not both be satisfied. Telecommunications equipment and vehicle software certified under one set of standards were refused approval under the other. Customs clearance times for the affected categories doubled.\n\nTrade diverted where it could. Mines and separation plants outside the dominant supplier raised output and magnet recycling expanded, but the first new processing capacity did not reach volume until the autumn of 2031. Governments released strategic stocks to defence and medical users first. Most had no legal basis for allocating industrial inputs among private firms and wrote one during the shortage.\n\nBy the middle of 2031, world goods trade volume was 10 per cent below its 2028 level. Inflation ran about one and a half percentage points above target in the bloc economies and about three points above target in economies that imported from both. Employment in export sectors fell in the most exposed manufacturing regions. Exemptions were negotiated product by product and each carried a condition on alignment.\n\nGINC's reading at the two-year mark was that outcomes depended less on which side a country stood with than on what it had prepared. Countries that had mapped their dependence by product, held stocks sized to requalification times and kept working customs and licensing administrations lost output for months. Countries that learned of their exposure only when production lines stopped lost output for years, and several gave up policy positions in order to obtain supply."

    "summary": "A sharp repricing of technology and commercial property assets triggers withdrawals from leveraged funds and from bank deposits that can move within hours. Global equities fall 40 per cent, cross-border private lending contracts by 25 per cent and borrowing spreads for vulnerable sovereigns rise by 500 basis points. Funding markets remain impaired for nine months. Several governments lose market access as bank support, unemployment spending and refinancing needs fall due together. The test for a nation is whether it can keep payments and essential services running and allocate losses without turning liquidity support into a public guarantee it cannot afford. The record continues the first-pass global financial crisis and absorbs the sovereign funding crisis as its national face.",
    "narrative": {
      "dateline": "November 2029",
      "text": "The repricing began in the second week of January 2029, when two of the largest listed technology companies cut their capital spending plans for data centres and a group of lenders marked down the office and data-centre loans that had been valued on the earlier plans. Within ten days three private credit funds had suspended redemptions and the banks that financed them were drawing on central bank facilities. Deposits moved faster than in any earlier episode: one mid-sized lender lost a fifth of its deposits in two working days, most of it through mobile applications outside business hours.\n\nBy the end of February global equities were 40 per cent below their peak. The major central banks reopened currency swap lines and bought government bonds to keep core markets working, and those markets held. The stress then moved to weaker borrowers. Cross-border private lending contracted by a quarter over the following two quarters as banks and funds reduced foreign exposures. Trade finance lines were cut for importers in South Asia, Africa and Latin America, and borrowing spreads for the weaker sovereigns rose by 500 basis points.\n\nThe fiscal demands then fell due together. Governments were asked to guarantee bank liabilities, pay for rising unemployment and refinance maturing debt in the same quarter, in markets that would lend only at short maturities. Eight governments lost market access between March and August. Two of them had guaranteed their banking systems in full in the first week and found that the guarantee had moved the doubt from the banks to the state. Four suspended payments on external bonds. Restructuring talks were slow because bondholders, bilateral lenders and commodity traders holding collateral had no common forum.\n\nIn the countries that lost access, the effects reached public services within weeks. Salaries for teachers and health workers were paid late or in part. Importers could not obtain foreign currency for fuel and medicines, and hospitals rationed supplies. Card and transfer systems continued to operate throughout, which limited the damage, but several governments imposed limits on withdrawals and on transfers abroad.\n\nFunding markets remained impaired for nine months. Issuance by investment-grade borrowers resumed in October 2029. By then unemployment in the advanced economies had risen by three percentage points, technology investment had fallen by a third and several large infrastructure projects had lost their financing. Central banks that held large quantities of government debt faced public pressure to hold more.\n\nThe governments that came through with their capability intact had three things in common. They held liquid reserves and long debt maturities at the start. They had resolution regimes that imposed losses on shareholders and creditors before public money was used. They limited liquidity support by amount and by time, and said so in public, so that it was not read as an open guarantee. Those that could not do this spent the following years servicing the cost."

A globally important strait loses 70 per cent of normal commercial traffic for 90 days, followed by six months of partial recovery. Strikes and cyber operations damage nearby ports, energy facilities and communications. At the peak, oil prices are twice and gas prices four times their pre-war level, and war-risk insurance on affected routes triples. Nations must manage defence commitments, evacuation, displaced people and fuel rationing together. The test assumes neither rapid victory nor nuclear escalation. The Strait of Hormuz is the default theatre; other straits are variants.",

      "dateline": "March 2031",
      "text": "The confrontation had been building for months, but the war itself began within a week. In early April 2030 an exchange of strikes between a regional state and a major power with forces in the Gulf became a sustained air, missile and naval campaign, and two partner states joined within days. War-risk underwriters withdrew standard cover for the strait on the third day. Owners held ships outside it, and transits fell from about a hundred a day to fewer than thirty, most of them under escort.\n\nThe closure lasted 90 days at that level. Missiles and drones damaged two export terminals, a gas liquefaction plant and a container port. Cyber operations interrupted port systems and a regional telecommunications operator for several days at a time, and satellite navigation was unreliable across the theatre. Crude oil reached twice its pre-war price in the fifth week. Spot gas reached four times its pre-war price in the eighth, when buyers in East Asia, South Asia and Europe were bidding for the same cargoes. War-risk premiums on the affected routes tripled.\n\nGovernments faced several tasks at once. Importing states released emergency stocks in the second week and introduced fuel allocation for industry in the fourth; several then found that their plans assumed a closure of 30 days. States with nationals in the region ran evacuations by air and sea while commercial flights were suspended, and neighbouring countries received displaced people in numbers their reception systems had not planned for. Allied governments were asked for ships, air defence interceptors and basing. Interceptors and precision munitions were used faster than they could be made. Reservists were recalled in the belligerent states and in two of their partners.\n\nThe economic effects reached beyond the energy importers. Fertiliser prices followed gas. Freight rates rose on routes far from the fighting as ships were rerouted and insurers repriced. Central banks tightened policy against inflation that came from supply, and finance ministries funded fuel subsidies and defence orders in the same budget. Low-income importers in Africa and South Asia cut fuel and food purchases as their currencies fell. Exporters outside the theatre earned more, and so did some defence manufacturers.\n\nNeither side won quickly and neither used nuclear weapons. Large-scale operations continued until October 2030, when a ceasefire held. Mine clearance and the return of insurers and crews took longer: traffic through the strait recovered only in part over the following six months and had not returned to its pre-war level by March 2031. The damaged terminals were still under repair and emergency stocks were being rebuilt at higher prices. Munitions stocks were below their pre-war levels in every state that had fought or supplied.\n\nThe states that came through with least loss had more than one supply route, stocks sized for months, tested allocation and evacuation plans and forces able to sustain an escort commitment. The others had plans for a closure or for a war, but not for both together over six months."

    "summary": "A hostile state conducts a deniable campaign below the threshold of war for 12 months: sabotage of subsea cables and energy assets, cyber intrusions, interference with satellite positioning, drone incursions and information operations. At the peak, reached over weeks, it activates concealed access to power and telecommunications systems. Areas producing half of national output lose reliable power and communications for 72 hours and essential services are rationed for 30 days. Attribution remains contested and threats to crews deter repair. The government must coordinate intelligence, operators and public communication, restore services by manual fallback and resist coercion without escalating before it can show evidence. Conventional invasion is outside this scenario.",
    "narrative": {
      "dateline": "June 2030",
      "text": "The campaign began in March 2029 and no single incident in it was an act of war. A data cable to the islands was cut by a dragging anchor, and the vessel's owner proved to be a company registered six weeks earlier. A fire destroyed a transformer depot; the men charged had been recruited through a messaging application. Satellite positioning failed across the eastern region for days at a time, and aircraft approach procedures, ambulance dispatch and farm machinery guidance failed with it. Drones closed the capital's airport twice in one month. Each incident was investigated and attributed some weeks later, and each attribution was disputed by accounts that had not existed a month before.\n\nOver the same months the security service found foreign access in the networks of two electricity distributors and one mobile operator. It was removed where it was found. It was not found everywhere.\n\nIn the second week of February 2030 the adversary used what remained. Protection settings at eleven transmission substations were changed remotely while control room displays continued to show normal values. Supply failed across the capital and the two industrial provinces, which together produced half of national output. Mobile networks ran on batteries for about four hours. Card payments stopped. Core systems at the mobile operator had been wiped, so restoring power did not restore service.\n\nReliable power and communications returned after 72 hours. Engineers restored the grid by driving to substations and switching by hand, because remote control could not be trusted. Two repair vessels sent to a damaged interconnector turned back after unidentified drones followed them and an anonymous warning reached their insurer. For the next 30 days electricity was supplied on a published rota. Hospitals, water treatment and food distribution were served first and industry worked three days a week. Several hospitals found that their fuel contracts had assumed an outage of 24 hours.\n\nThe government did not name the state responsible for nine days. The intelligence assessment was firm but rested on sources that could not be published, and ministers judged that an accusation without public evidence would divide allies. During those nine days a forged cabinet memorandum circulated which appeared to show that neglected maintenance had caused the outage. A message passed through a third government offered restraint in exchange for withdrawal from a defence agreement. The offer was refused. Allies consulted, issued a statement and sent grid engineers and mobile generation, but agreed no collective measure.\n\nBy May 2030 services were normal. The costs that remained were of a different kind. Two foreign manufacturers deferred planned plants and insurers excluded state-backed sabotage from infrastructure cover. A parliamentary inquiry recorded that no minister had held authority over operators, the intelligence service and public communication at the same time. It also found that households which had kept water, a battery radio and cash managed the 72 hours with little difficulty, and that fewer than one in three had done so."

Revenue collection and essential service delivery fall, and national output runs 5 per cent below its previous path. Courts and official information become contested instruments. Physical assets are undamaged. The state must restore accepted authority without normalising repression or permanent emergency powers.",
    "narrative": {
      "dateline": "October 2031",
      "text": "The presidential runoff was held on 6 October 2030. The electoral commission announced a margin of 0.8 percentage points on 9 October, after a three-day delay in the count in two provinces. Within hours a video appearing to show ballot papers being loaded into an unmarked vehicle had been viewed 14 million times. Forensic analysts established within two days that it was synthetic. The correction reached about a tenth of that audience. Both candidates declared victory. On 21 October the constitutional court suspended certification pending a review of evidence of foreign-funded online campaigning. The outgoing government treated the order as binding. The declared winner did not.\n\nBy November there were two claimants to the presidency, each citing a lawful basis. Protests recurred weekly in the capital and four provincial cities. Election officials and three judges received coordinated threats, and two regional returning officers resigned. Police commanders in two provinces declined orders to clear occupied administrative buildings. One army garrison stated that it would take instructions only from the court. No unit changed sides and there was no sustained armed confrontation.\n\nNormal administration stopped in provinces containing about 20 per cent of the population. Tax offices and customs posts there closed or remitted to provincial authorities, and national revenue ran 15 per cent below plan between November and March. Teachers and health workers in those provinces were paid late in four of the six months. Clinics reported shortages of basic medicines. The statistics office suspended two releases after both sides challenged its figures, and the central bank set policy without them.\n\nThe currency fell 18 per cent in six weeks. Two bond auctions were cancelled and the government financed itself through short-term bills taken up by domestic banks. Mobile data was restricted on eleven days under an emergency decree that was renewed twice. Firms postponed investment. Permits and contract payments that needed a ministerial signature went unsigned because officials could not establish who was authorised to give it.\n\nA mediated agreement in April 2031 set a rerun under a reconstituted commission, with regional observers and an agreed protocol for testing evidence. The rerun was held in September 2031 and the losing side accepted the result. Output for 2031 was 5 per cent below the path forecast before the vote. The emergency decree lapsed, but three of its provisions on public assembly had been written into ordinary law, and surveys showed that fewer than a third of respondents trusted the commission to run the next election.\n\nRoads, power stations and ministries were undamaged throughout. For six months the state lacked agreement on who was entitled to direct them."

    "summary": "Extreme heat and drought cut exportable grain from two major producing regions by 25 per cent in the same season. Export restrictions by other suppliers and a fertiliser shortage prevent rapid substitution. International staple prices double and stay there for 18 months, and physical import availability falls 15 per cent for highly exposed buyers. Water shortages also constrain domestic harvests and power generation in the affected regions. Governments must protect nutrition and farm viability while managing scarce foreign exchange, cross-border water disputes and unrest over food distribution. Exporters that are not affected and holders of usable stocks gain; poor consumers, food importers and water-stressed producers lose.",
    "narrative": {
      "dateline": "September 2031",
      "text": "The losses were confirmed in two stages. In July 2029, after seven weeks of extreme heat during grain filling, crop surveys in the first producing region cut the expected wheat and maize harvest by almost a third. In October the second region, in the other hemisphere, reported that drought had reduced its planted area and yields by a similar margin. Taken together, the grain available for export from the two regions was 25 per cent below the five-year average.\n\nPrices moved before the second report. By November international wheat, maize and rice prices were double their level of a year earlier, and they stayed near that level until the spring of 2031. Eleven governments restricted staple exports within ten weeks of the first report, most by quota or licence and a few by outright ban. Three of them were suppliers with normal harvests. Importers holding contracts found that cargoes were delayed, re-priced or cancelled under force majeure clauses. For the most exposed buyers, delivered volumes over the following year were 15 per cent below requirement.\n\nThe same drought lowered reservoirs. Hydropower output in the affected regions fell by a fifth, irrigation allocations were cut and two governments in a shared basin disputed releases from upstream dams. Gas-fired generation covered part of the gap and raised the cost of nitrogen fertiliser, which several producers had already stopped exporting. Farmers in importing countries applied less in the 2030 season and yields there fell, so the shortage lasted beyond the season in which it began.\n\nGovernments with physical reserves near their cities released them in the first three months. Those whose reserves were financial, or were stored at ports far from consumers, could not turn them into food at the pace required. Bread and rice subsidies that had cost 1 to 2 per cent of GDP doubled. Central banks in importing economies spent reserves defending their currencies as food import bills rose, and nine governments sought emergency balance of payments support. Humanitarian appeals for 2030 were less than half funded.\n\nRationing was introduced in fourteen countries. Where distribution was seen to be fair, it held. Where subsidised grain was diverted or queues were policed by force, protests spread from the capital to provincial towns, and two governments fell during 2030. Acute malnutrition among children under five rose in every low-income importing country that reported data. Herds were slaughtered early in the drought regions, and many small farms did not plant the following season because they could not finance seed and fertiliser.\n\nHarvests recovered in 2031 and prices fell back within months. Stocks did not recover as quickly: the rebuilding of public reserves kept import demand high into 2032. The countries that came through with least damage had held reserves of the right grains near the people who needed them, had transfer systems that could reach households within weeks and had kept enough foreign exchange to buy when others could not."

Key transport, water and health assets in the core operate below half capacity for 30 days. Reconstruction takes two years and insurance covers less than half the loss. The scenario does not impose an identical physical hazard on every nation. It tests evacuation, continuity of essential services and recovery finance. It is the only natural-hazard test among the twenty.",
    "narrative": {
      "dateline": "November 2031",
      "text": "The cyclone made landfall on 14 September 2029, forty kilometres from the capital, at the top of a spring tide. Forecasters had given four days' notice and the evacuation order was issued 36 hours before landfall. About 60 per cent of those ordered to leave did so. The river embankments on the eastern side of the city, last strengthened four decades earlier, were overtopped in three places during the night.\n\nBy the morning of 15 September, water stood in districts that held a tenth of the national population and produced close to a third of national output. The container port closed. The two main rail approaches and the airport access road were cut. Four of the nine water treatment works lost power or were contaminated, and supply to the metropolitan area fell to 40 per cent of normal. Three of the region's largest hospitals evacuated their patients. The others worked on generators, with fuel delivered by the army. Mobile coverage in the flooded districts failed within twelve hours as the batteries at base stations ran down.\n\nThe acute phase lasted a month. For those 30 days, port throughput, piped water and hospital capacity in the capital region stayed below half their normal levels. The central government ran the response from a secondary site because its own operations centre was inside the flood zone. Payment of emergency grants began in the third week, once the civil registry had been restored from a copy held in another city. Households without bank accounts or identity documents waited longer.\n\nThe assessment published in December 2029 put direct damage at 8 per cent of annual GDP. Insurers and the national catastrophe pool covered 38 per cent of the loss. The rest fell on households, small firms, the municipality and the central budget. The government drew its contingent credit line in the first week and its catastrophe bond paid out in November. Together these met less than a fifth of the public reconstruction bill. The remainder was financed by a supplementary budget, reallocated capital spending and new borrowing at a wider spread.\n\nOutput in the quarter after landfall was 5 per cent lower than a year earlier. Exporters that depended on the port lost contracts to suppliers in neighbouring countries and some did not regain them. About 300,000 people were still in temporary housing six months later. Two insurers withdrew flood cover from the low-lying districts in 2030 and mortgage lending there slowed.\n\nReconstruction was declared complete in September 2031, two years after landfall. The embankments were rebuilt to a higher standard and the operations centre was moved. The parliamentary inquiry found that the forecast and the warning had worked. It attributed the scale of the loss to three conditions that had been known beforehand: the state of the eastern defences, the siting of critical facilities inside the flood zone and the absence of finance arranged before the event."

Over the following three years, employers in highly exposed economies remove or radically redesign jobs equal to 10 per cent of employment. Entry-level recruitment in affected occupations halves before training and benefit systems adapt. Productivity gains accrue mainly to model owners and leading adopters, while employment-linked tax receipts fall 10 per cent below plan. Services exporters lose outsourcing contracts. The test is whether a nation can absorb the displacement without losing its supply of skilled entrants, its public revenue or public trust in economic opportunity.",
    "narrative": {
      "dateline": "March 2031",
      "text": "The step came in the first half of 2028. Within a few months, three providers released agent systems that completed administrative and professional tasks lasting several days, at an error rate below that of a supervised junior employee and at a cost per task that fell by more than half during the year. Until then, firms had used AI to assist staff. From the autumn of 2028 they assigned it whole workflows: claims handling, accounts payable, contract review, first-line customer service, software maintenance and routine reporting.\n\nHeadcount did not fall first. Recruitment did. In the highly exposed economies, graduate and trainee intakes in the affected occupations for 2029 were about half those of 2027. Redundancies followed through 2029 and 2030, as firms redesigned processes around the agents and as slower competitors lost contracts to faster ones. By early 2031, jobs equal to 10 per cent of employment in these economies had been removed or changed so far that the previous holder could not fill them without retraining. About a third of the displaced workers had found work at comparable pay.\n\nOutput rose. Measured productivity in business services grew faster than at any time in two decades, and corporate profits rose with it. The gains were concentrated in the firms that owned the models and in the early adopters. Public revenue moved the other way. By the third year, income tax and social contributions were 10 per cent below budget plans, because those plans had assumed that rising output would bring rising payrolls. Corporate tax receipts increased by less than the payroll shortfall, and part of the profit was booked abroad.\n\nBenefit systems designed for cyclical unemployment met claimants who were qualified, in mid-career and unlikely to be recalled. Public employment services had training places for a small fraction of them, and many courses prepared people for occupations that were themselves contracting. Universities recorded falling applications for law, accountancy and computing degrees. Professional bodies reported that the supervised junior work through which practitioners had qualified no longer existed in sufficient volume.\n\nServices exporters were affected through trade. Clients renegotiated outsourcing contracts for back-office work and software maintenance at lower volumes or took the work back in-house. Export receipts from business services fell in several South Asian and South-East Asian economies, where the sector had been the main source of graduate employment.\n\nSurveys in 2030 recorded a marked fall in the share of young adults who expected to be better off than their parents. Legislatures debated taxes on automated work, restrictions on deployment in regulated professions and wage insurance. Few had legislated by 2031. The nations that held their position had kept entry routes open through funded traineeships, moved the tax base towards profits and consumption, retrained at scale and used the same systems to improve public administration."

    "summary": "An adversary demonstrates a practical quantum attack on widely used public-key cryptography (RSA and elliptic-curve algorithms) by decrypting intercepted material and forging selected digital signatures. Within 30 days, governments and financial operators must revoke vulnerable credentials and suspend some cross-border services. Sensitive data collected and stored in earlier years become readable. Emergency migration to post-quantum algorithms takes 12 months because embedded devices and supplier software cannot all be replaced at once. Physical networks keep operating, but confidence in authentication, confidential exchange and the legal validity of digital transactions falls sharply. Symmetric encryption with long keys is assumed to hold.",
    "narrative": {
      "dateline": "March 2032",
      "text": "On 9 March 2031 three foreign ministries received copies of their own diplomatic cables from 2024, in plain text, through an intermediary. Within the week a software update carrying a valid signature from a large operating-system supplier was found on test machines at two central banks. The supplier's signing key had not been stolen. Forensic teams in four countries reached the same conclusion: the private key had been computed from the public one. A state held a quantum computer able to break 2048-bit RSA and 256-bit elliptic-curve keys at a rate of about one key a day, and had chosen to show it.\n\nThe rate mattered. The adversary could not read everything, but no defender could tell which keys it had already taken. Root certificates, code-signing keys and interbank message keys were treated as compromised. In the first 30 days governments and financial operators revoked credentials in order of consequence. Seven national identity schemes suspended remote signing. Several payment systems limited cross-border instructions to counterparties that had already moved to post-quantum algorithms or pre-shared symmetric keys, and correspondent banks reintroduced call-back confirmation and value limits. Electronic bills of lading were refused at a number of ports and paper documents returned.\n\nNothing physical failed. Power, telecommunications and data centres operated throughout. What stopped was the assurance that a message came from its sender, that a record had not been altered and that a signature would stand in court. Courts in several jurisdictions were asked whether contracts signed with revoked algorithms remained valid, and legislatures passed validating acts for documents signed before the disclosure date.\n\nNations that had completed cryptographic inventories and deployed hybrid key exchange on their main systems before 2030 finished the urgent work in about four months. Others found that they did not know where the vulnerable algorithms were. Smart cards, hardware security modules, industrial controllers, vehicles and medical devices held keys that could not be changed remotely, and replacement units were on allocation for most of the year. Specialist engineers were scarce and moved to the employers that paid most. Smaller states depended on a few foreign cloud and certificate suppliers for the timetable of their own recovery.\n\nThe larger loss was retrospective. Traffic intercepted and stored since the 2010s became readable at a pace the adversary chose. Agent identities, negotiating positions, health records and commercial secrets from two decades had to be assumed exposed. Selected disclosures continued through 2031 and were timed to coincide with negotiations and elections. Forged documents carrying valid signatures under the old algorithms circulated beside genuine ones, and official denials had limited effect.\n\nBy March 2032 most critical systems in advanced economies ran on post-quantum algorithms. Long-lived devices and many public registries in lower-income countries did not. The event was not an outage, and continuity plans written for outages did not apply. The capability it tested was knowing where trust was held in each system and being able to replace it in order of consequence."

It infects 30 per cent of the population during the first year, with an infection fatality ratio of 0.5 per cent before effective countermeasures, implying deaths of about 0.15 per cent of the population. Peak hospital demand reaches twice available staffed capacity in highly exposed nations. Effective vaccines are unavailable at scale for nine months and workplace absence reaches 15 per cent at the peak. Governments must sustain ordinary care, essential production and credible communication while allocating scarce treatment. The scenario tests staffed health capacity, access to countermeasures and public trust, not bed counts or written plans.",
    "narrative": {
      "dateline": "March 2031",
      "text": "The first clusters of severe pneumonia were reported in late September 2029. By the time a reliable diagnostic test was in general use in mid-October, the virus had been sequenced from patients in 34 countries on five continents. Containment at the border was no longer available to any government. Early estimates put the infection fatality ratio at 0.5 per cent and the estimate held through the winter.\n\nHospitals in the first affected cities reached the limit of their staffed beds in week six. At the national peaks, demand for hospital care ran at twice staffed capacity in the most exposed nations. The binding constraint was staff, then oxygen. Beds and equipment could be added in weeks; trained nurses could not, and 15 per cent of the workforce was absent at the peak through illness, isolation or care for dependants. Health ministries adopted allocation rules for intensive care that most had drafted and few had exercised. Elective surgery, cancer screening and routine immunisation were suspended for months. Maternity services were kept open by redeploying staff from other wards.\n\nMore than 20 governments restricted exports of protective equipment, medicines and vaccine inputs within the first two months. Nations with regional manufacturing and advance purchase agreements received their first vaccine deliveries in month five, in quantities sufficient only for health workers. Supply at scale began in June 2030, nine months after the first reports, and reached most low-income nations in 2031.\n\nAbsence spread from hospitals to food distribution, freight, water treatment and power operations. No essential network failed outright, but most ran on reduced rosters and deferred maintenance. Schools closed for four months on average, and pupils without a device or a connection at home did not return at the same rate as others. Global output fell 4 per cent in 2030. Governments borrowed to support incomes, and several that had entered the pandemic with high debt and low reserves sought emergency lending within the year.\n\nPublic communication determined how long measures held. Where authorities published their data, stated what was unknown and explained allocation decisions, compliance lasted through the second wave. Where guidance changed without explanation, or contradicted what hospital staff were saying in public, false claims about the origin of the virus and the safety of the vaccine reached a majority of adults and vaccine uptake stalled below 60 per cent.\n\nBy the end of the first year about 30 per cent of the world's population had been infected and more than 12 million people had died. The nations with the smallest losses were not those with the most hospital beds in their plans. They were those that could staff the beds, keep ordinary care and essential production running and retain public belief in what the authorities said."

External public debt service falls by 40 per cent for five years through maturity extensions, interest reductions and selective principal relief. New concessional lending finances essential investment and may not be used to repay creditors. Participating governments regain room for health, education and infrastructure, but must publish credible budgets and run transparent procurement. Creditors take losses and borrowers outside the framework may pay more to borrow. The test is whether fiscal release becomes durable capability, not renewed borrowing or politically allocated spending.",

      "dateline": "November 2031",
      "text": "The common framework was adopted in March 2030 by the main official bilateral creditors, Chinese state lenders and a committee representing the largest bondholders. It set one sequence for every case: a debt sustainability analysis published within 60 days, a single creditor committee, comparable treatment enforced by a most-favoured-creditor clause and a standstill on payments while terms were agreed. Legislation passed in New York and London the previous year limited what a holdout creditor could recover in court.\n\nBy September 2031, 27 states had concluded agreements. Most were in Africa, with others in South Asia, Latin America and the Caribbean, Central Asia and the Pacific. The terms differed by case but met the same test: external public debt service fell by 40 per cent for five years. Maturities were extended by 12 to 15 years, interest rates were cut and six states received a reduction in principal. Multilateral lenders did not take losses. They committed new concessional loans that could be drawn only against published investment plans and not to repay other creditors.\n\nIn one East African finance ministry, interest payments had taken 31 per cent of revenue in 2029. The 2032 budget put them at 18 per cent. The difference was assigned to clinic staffing, primary school construction and a transmission line that had been suspended since 2027. Each allocation was published by project, and contracts above a set value went through an open tender portal reviewed by the national audit office.\n\nResults were uneven. Rating agencies moved every participant to selective default at signing, and 19 had been upgraded by November 2031. Among the 27, GINC identified nine where capital spending rose and was executed, eleven where the release went mainly to wages and subsidies before elections and seven where arrears and state enterprise losses absorbed most of it. Two governments returned to commercial borrowing within a year at rates above those they had just restructured. One agreement was suspended after an audit found contracts awarded without tender.\n\nCreditors recorded losses. Bondholders accepted a reduction in present value of about 30 per cent on average, and two funds pursued litigation that failed under the new statutes. Chinese state lenders extended maturities on most claims and wrote down few. Borrowers that had not applied reported higher spreads for about a year, as investors priced the possibility that they would apply later. Several governments that had cut spending to stay current said the framework favoured those that had not.\n\nThe five-year period of reduced payments ends in 2036. Whether the participating states can then service the remaining debt depends on what the released funds bought: revenue administration, schools, power and transport links that raise output, or commitments that must be paid for again."

    "narrative": {
      "dateline": "March 2032",
      "text": "The compact was signed in February 2028 by 31 governments on four continents and entered into force on 1 January 2029, once the minimum number of ratifications had been deposited. Its members accounted for about a third of world output. On the first day, nine tariff lines in ten among them went to zero or began a five-year reduction. The clauses that mattered more took effect over the following year: one rule of origin that let inputs from any member count towards qualifying content; mutual recognition of engineering, nursing and accounting qualifications; common rules on data transfers and electronic documents; and acceptance of each other's product traceability records.\n\nFirms responded before governments did. Within eighteen months, announced factory, logistics and data-centre investment into members ran 30 per cent above its earlier path, and most of it went to a small number of places. A textile and electronics corridor formed between South Asian ports and East African processing zones. Vehicle component makers moved lines from non-member suppliers to member states in South-East Asia and Latin America so that finished vehicles would qualify. By the end of 2031, trade among members was 20 per cent higher than the projection made before the compact.\n\nThe gains followed capability, not membership alone. Members whose standards laboratories were accredited and whose customs systems accepted electronic certificates saw suppliers qualify within months. In others, exporters waited more than a year for test results that buyers would accept, and investment committed to them was reassigned to neighbours. Ports that could not add berths turned vessels away. Two members rationed industrial power connections. Training colleges in the faster-growing corridors could not supply enough technicians, and recognised qualifications allowed nurses and engineers to leave poorer members for richer ones.\n\nThere were losses inside the compact as well. Protected producers of steel, sugar and vehicles in several members lost market share within two years, and three governments used the safeguard clause. Tariff revenue fell in members that had relied on it and two revised their budgets during the year. Capital inflows raised exchange rates in the main recipient economies and made their other exports less competitive.\n\nNon-members did not share in the gains by default. Economies that competed directly with new members for assembly work recorded foreign investment about a tenth below earlier levels, and their exporters faced tariffs that their rivals no longer paid. Six applied to join in 2031. The list of applicants, and the conditions set for them, became the compact's main source of influence over economies outside it."

Within 18 months of entry into force, restricted trade worth at least 1 per cent of global GDP becomes accessible again. Competition continues under clearer rules, and unrelated regional wars are not assumed to end. Nations must revise industrial policy, supplier arrangements and defence planning. Protected producers and economies that gained from trade diversion face immediate adjustment.",

      "text": "The agreement was signed in Geneva in September 2029 and entered into force in January 2030, after fourteen months of talks that began with a near-collision between naval vessels in the Taiwan Strait. It had three parts. The first removed, in four stages over 18 months, about 80 per cent of the bilateral tariffs imposed since 2018. The second replaced blanket export restrictions on mature semiconductors, rare earth materials and commercial software with a published list and a 60-day licensing deadline. Controls on the most advanced chips, on leading-edge chipmaking equipment and on military end uses stayed in place. The third set rules for encounters between military ships and aircraft, opened a staffed crisis line between theatre commands and required notice of large exercises near Taiwan. It did not address sovereignty. Each government restated its existing position in a separate annex.\n\nA joint commission met each quarter and published compliance data. By June 2031 it had recorded two disputes over licensing delays, both settled within the 90-day procedure. Bilateral goods trade was 35 per cent higher than in 2029. Counting inputs and equipment that third-country firms could again sell to both markets, the trade reopened was a little over 1 per cent of global GDP. Container rates on Pacific routes fell and insurers reduced war-risk loadings for the Taiwan Strait.\n\nThe adjustment was immediate for some. Battery, solar module and mature chip plants in North America and Europe that had been financed on a tariff margin reported losses within two quarters, and three governments extended subsidies they had planned to end. Assembly orders that had moved to Vietnam, Mexico, Malaysia and India after 2018 partly returned to direct routes. Export growth in those economies slowed sharply in 2030, although capacity already built stayed in place. Suppliers of rare earths and gallium outside China lost the price premium that had supported new mines.\n\nAllied governments had not been party to the talks. Several in the Indo-Pacific and Europe reviewed defence plans that had assumed a rising risk of confrontation. Most held spending flat in real terms and did not cut it, because wars elsewhere continued and either party could end the agreement on six months' notice. Legislatures in both capitals held hearings on verification. One chamber voted on a motion to suspend the second tariff stage, and the motion failed.\n\nBy the first review, the states that had gained most were those with open trade, competitive exporters and regulators able to revise industrial policy quickly. Those that had lost most had built capacity or diplomatic leverage that depended on the restrictions remaining."

      "dateline": "November 2030",
      "text": "The framework was signed in the spring of 2029 after fourteen months of talks hosted by two Gulf states and attended by four external guarantors. It did not settle borders, recognition or the status of contested territory. It set three things. The first was a guarantee for commercial shipping through the Strait of Hormuz, Bab el-Mandeb and the southern Red Sea, run from a joint maritime coordination centre. The second was a set of monitored ceasefires on four fronts, with observers reporting each month. The third was sanctions relief in five stages, each released by an inspection report on specified missile and nuclear activities.\n\nThe first year was measured in transits and premiums. Container lines returned to the Red Sea route in the fourth month, after two inspection reports and ninety days without an attack on a merchant vessel. By the twelfth month, transits through both straits were within 5 per cent of their pre-conflict average and war-risk insurance costs on the affected routes had fallen by 55 per cent. Freight rates between Asia and Europe fell as voyages shortened by about ten days.\n\nTwo donor conferences produced reconstruction commitments equal to 10 per cent of the participating conflict-affected economies' combined annual GDP, payable over three years. Disbursement ran behind. By the first anniversary, 22 per cent of the first-year tranche had been spent. The constraints were administrative. Property registries had been destroyed or duplicated, procurement offices were short of staff and contractors waited for unexploded ordnance to be cleared. Where municipal governments restored water, electricity and schools, residents returned and stayed. About 2.1 million displaced people went home within eighteen months. In districts without services, a third of them left again within a season.\n\nThe settlement was resisted. Armed groups that had earned revenue from checkpoints, smuggling and protection lost sponsors and income. Some turned to kidnapping and to attacks on reconstruction sites. Two ceasefire lines recorded serious violations. One of them suspended the third stage of sanctions relief for eleven weeks, until inspectors regained access to a missile production site. Courts and truth commissions were contested from the start. Amnesty provisions that kept commanders inside the settlement were opposed by victims' associations, and three governments faced sustained protest over detainees and missing persons.\n\nOutside the region the effects were smaller and uneven. Energy importers in Asia and Europe paid less for crude oil and liquefied natural gas as the risk premium narrowed. Higher-cost oil exporters, operators on the Cape route, war-risk underwriters and suppliers of missile defence lost income. Defence ministries in the region deferred orders but did not cut budgets.\n\nBy late 2030 the framework had passed its first verification cycle. Governments that delivered inspections, services and returns on schedule received most of the private reconstruction investment. Those that did not retained the ceasefire but attracted little investment, and their returning residents were the first to leave again."

      "dateline": "June 2035",
      "text": "The result that changed investment decisions was published in September 2030. Independent engineers had audited eleven commercial plants in five climate zones over two full years. Each combined solar or wind generation, battery storage and one firm clean source: enhanced geothermal at seven sites, small modular fission at two and long-duration storage at two. All eleven had met a contracted reliability standard of 99.9 per cent of hours at a delivered cost 40 per cent below a new gas or coal plant in the same market. The designs were standard and the audit data were public.\n\nLenders acted on the finding within months. By early 2032 standardised projects were reaching financial close in 18 months or less from first application, and their cost of debt had fallen below that of new thermal plant. Developers ordered the same module, cell and drilling packages in volume. Orders for transformers, cable and rigs exceeded supply within a year, and prices for lithium, copper and graphite rose sharply before new capacity arrived.\n\nThe gain was not distributed by resource. It was distributed by the ability to connect. Nations that had approved transmission corridors, staffed their permitting offices and reformed wholesale markets to pay for firm capacity brought projects into service in three years. Their industrial electricity costs were 30 per cent lower by 2035, and smelters, chemical plants, electrolysers and data centres signed 15-year supply contracts there. Nations with connection queues of five years or more saw the same projects financed and then left waiting. Several curtailed large volumes of midday output while still paying for imported gas in the evening.\n\nImporters of oil and gas recorded lower fuel bills from 2033 as heat, transport and industry electrified faster than planned. Households saw the difference later than industry, because network charges rose to pay for the new lines.\n\nThe loss arrived through expectations before it arrived through volumes. Long-term demand forecasts for oil, gas and coal were revised down in 2031 and again in 2032. Reserves were written down, new field developments were cancelled and the borrowing costs of hydrocarbon-dependent states rose while their export receipts were still close to normal. Producers with low costs and large sovereign funds maintained output and used the interval to diversify. Producers without buffers cut capital spending first, then subsidies and public pay. Three had requested external financing programmes by 2034. Utilities holding recently built gas and coal plant sought compensation for early closure, and coal regions lost employment faster than retraining schemes could absorb.\n\nBy June 2035 the threshold itself was no longer in dispute. The remaining questions were administrative: how quickly a state could approve a line, train electricians and drillers, secure materials and replace a revenue base."

    "summary": "Multi-country field trials validate a transferable package of climate-resilient staple varieties, precision irrigation and soil management. Linked agreements on seed approval, smallholder finance and extension start simultaneous deployment across the major low-yield regions. Within four growing seasons, adopting farms raise staple output by 25 per cent and cut water use per tonne by 30 per cent. Improved storage preserves the additional harvest and international staple prices fall 15 per cent. Food importers and adopting farmers gain; high-cost exporters and farmers without access to finance or seed lose relative income. The test for each nation is affordable smallholder adoption without greater land concentration, exclusion from seed access or higher total water withdrawals.",

      "dateline": "November 2033",
      "text": "The trial results were published in February 2029. Over three seasons, at 140 sites in 22 countries, a combined package had been tested against local practice: drought-tolerant and heat-tolerant staple varieties, some of them gene-edited, with scheduled low-volume irrigation and a soil protocol of residue retention, targeted nitrogen and reduced tillage. No single component was new. The finding was that the combination transferred. Across maize, rice, wheat and sorghum sites, output per hectare rose by between 18 and 34 per cent and water applied per tonne fell by about a third.\n\nDeployment was negotiated, not left to the market. In July 2029, 31 governments, the principal seed licensors, public breeding institutes and a group of development lenders signed three linked agreements. The first allowed a variety approved by one participating regulator to be registered by the others within 90 days. The second capped trait fees for farms under five hectares and permitted saved seed for the open-pollinated lines. The third financed input credit, irrigation equipment and extension through national banks and co-operatives, with repayment after harvest.\n\nSeed multiplication was the first constraint. In the 2029–2030 season certified seed covered under a tenth of the target area and several governments rationed it by district. By the fourth season the package covered about 40 per cent of staple area in the participating low-yield regions. Adopting farms recorded staple output 25 per cent above their previous average and water use per tonne 30 per cent lower. Hermetic bags, village stores and better drying meant that the additional grain was sold through the year and not all at harvest. International staple prices in 2033 were 15 per cent below their 2028 level in real terms.\n\nResults differed sharply by country. Where land records were reliable, extension staff were in post and credit reached tenant farmers and women, adoption was broad. Where credit required a land title, larger farms adopted first, bought or leased neighbouring plots and took most of the gain; two governments suspended land transfers in irrigated districts in 2032. In several river basins lower water use per tonne did not reduce total withdrawals, because farmers expanded irrigated area until regulators set basin limits. Three participating states delayed approval of the edited varieties after court challenges and their farmers bought seed informally across borders.\n\nFood-importing nations reported lower import bills and lower food inflation by 2032. Grain-exporting regions reported the opposite: lower farm-gate prices, falling cropland values in higher-cost districts and requests for public support. Rice exporters in South-East Asia lost volume to buyers that had moved closer to self-sufficiency. Nutrition surveys in 2033 showed the first measurable falls in child stunting in the districts that adopted earliest. The same surveys showed no change in districts the package had not reached."

      "dateline": "November 2031",
      "text": "The verification report was published in February 2029. Eleven laboratories in seven countries, none funded by the developers, had been given the same systems and the same three tasks. In each field the system proposed hypotheses, designed experiments, ran them on automated equipment and revised its plan from the results. The laboratories reproduced a class of antibiotic candidates active against resistant infections, a solid electrolyte that kept its conductivity through 2,000 charge cycles and an enzyme that reduced the energy used in a common chemical step. The report's conclusion was narrow. The systems failed on problems outside the three fields. Within them they worked, and the results could be repeated.\n\nLicences were on sale by the summer and two open versions followed within the year. Access proved to be the smaller constraint. A system could propose 400 candidates in a week; a national laboratory with manual equipment could test 12. By 2031 the programmes that qualified, those with automated laboratories, reliable compute and staff able to judge the output, had halved the time from target to validated candidate and cut the cost per candidate by about the same. Programmes without those things reported little change.\n\nThe effect on business came quickly. Contract research firms that sold screening by the hour lost a third of their orders in two years. Three large pharmaceutical companies wrote down their early-stage pipelines and bought laboratory capacity. Patent offices received filings in volumes they could not examine, and courts in four jurisdictions gave different answers on whether a discovery made by a system could be patented and by whom. Medicines regulators became the limiting step. The agencies that had prepared rolling review and accepted automated evidence cleared candidates into trials a year ahead of the others, and developers moved their first filings to them. Trials themselves took as long as before.\n\nGovernments handled the dual-use problem unevenly. The biological design capability that produced the antibiotics could be directed at harmful agents, and the open versions could not be recalled. Fourteen countries adopted synthesis screening and tiered access rules; others did not. Defence ministries funded materials programmes on the same systems and classified the results.\n\nBy November 2031 the gains were measurable and concentrated. Five jurisdictions held most of the new patents. Countries that had equipped laboratories, trained evaluators and reformed approval pathways before 2029 captured discoveries in their own priorities, including neglected diseases and local crops. Countries that had relied on licences alone bought the products later, at the owners' prices. Research staff moved towards the equipped sites. No system had exceeded human experts across all fields, and the developers reported no self-sustaining acceleration of their own research. The step was a change in the cost of discovery in three fields. What separated nations was the capacity they had built to use it."

      "dateline": "April 2031",
      "text": "The switch took place on 1 March 2029. Two months earlier the audit office had published the results of the independent tests. The security review had found no unresolved critical faults. The inclusion trial, run across 40 districts, had shown that 96 per cent of adults could complete a payment and a records request, alone or with an assistant. The law had made both reports a condition of the switch.\n\nBy March 2031, 90 per cent of adults had used the identity, payment and data exchange services in the previous quarter. The median time from an approved benefit claim to payment had fallen from 20 days to four. The revenue authority estimated that the tax compliance gap had narrowed by a quarter, mainly because invoices and payments between registered firms were now matched automatically. Every contract above the publication threshold, and every decision on a licence or a benefit, carried a record that the audit office and the applicant could read.\n\nThe gains were contested. About 60,000 licensed agents, form writers and payment handlers lost most of their fee income within a year. Their associations brought two court challenges and organised stoppages at district offices. In three provinces, officials who had controlled land and licence files delayed the transfer of records until the audit office published a list of the offices that had not complied. The new records identified a cartel in road maintenance contracts, and 14 officials were charged.\n\nExclusion was the harder problem. The speech interface performed poorly in two minority languages. Fingerprint authentication failed for older manual workers at four times the national rate. The assisted counters, which the law required in every district, handled 11 per cent of all transactions in the first year and 7 per cent in the second. A proposal in 2030 to close them was withdrawn after the inclusion auditor reported that closure would leave 1.5 million adults without access. The automated eligibility model for housing support was suspended for five months after a review found that it rejected applicants with irregular income at twice the expected rate.\n\nThe system failed in service once. An outage of nine hours in August 2029 stopped online authentication. Pharmacies and benefit offices used the offline procedure and payments were reconciled the next day. In 2030 the interior ministry requested bulk access to payment records. The data protection authority refused and the court upheld the refusal.\n\nTwo neighbouring states that made a similar switch without published tests reported higher enrolment and lower use. GINC's assessment was that the result depended less on the software than on four conditions: tests before the switch, a staffed offline route, records open to audit and a regulator able to refuse the state."

    "summary": "Large trials establish that a low-cost combination of metabolic treatments and biomarker-guided prevention reduces major cardiovascular and diabetes complications by 30 per cent among eligible patients. Broad licensing and regional production make treatment affordable in most nations within two years. Health systems that adopt it reduce avoidable hospital admissions by 15 per cent over five years and raise working-age participation. To capture the gain a nation must identify eligible patients, sustain primary care and change payment incentives. Longer healthy lives alter pension and workforce assumptions. Providers that depend on treating preventable complications lose revenue, and populations that primary care does not reach fall further behind.",

    "narrative": {
      "dateline": "November 2034",
      "text": "The two trials reported within six weeks of each other in the spring of 2028. Together they had followed 64,000 adults in 29 countries for four years. Patients selected by a short panel of blood and urine markers and given a daily combination of off-patent and newly licensed metabolic medicines had 30 per cent fewer heart attacks, strokes, cases of kidney failure and amputations than those given usual care. The effect held across income groups and in both sexes.\n\nThe price mattered as much as the result. The rights holders agreed non-exclusive licences covering 140 countries before the end of 2028. By early 2030 manufacturers in India, China, Brazil, Egypt and South Africa were supplying the combination at under US$6 a month. The marker panel ran on equipment that most district laboratories already had.\n\nWhat followed divided nations by their health systems more than by their income. Where primary care held a register of patients and was paid for keeping them well, eligible adults were called in, tested and started on treatment within months. Community health workers and pharmacists did most of the monitoring, supported by decision software. In those systems avoidable admissions for cardiovascular and diabetic complications were 15 per cent lower in 2034 than in 2029, and disability claims among people aged 50 to 64 had fallen. More women were in paid work, in part because fewer were caring for a relative after a stroke.\n\nWhere hospitals were paid by the admission and primary care was thin, the medicines reached pharmacies and went little further. Uptake followed the ability to pay for a consultation. Several middle-income nations recorded a widening gap in cardiovascular deaths between cities and rural districts, and between insured and uninsured workers.\n\nThe fiscal effects arrived in a different order from the health effects. Finance ministries booked lower hospital spending slowly, because beds that emptied were filled from waiting lists. Actuaries moved faster. Mortality tables revised in 2032 added about a year to projected life expectancy at 60 in adopting nations, and pension schemes that had assumed otherwise reported larger deficits. Four governments brought forward legislation on pension age. Dialysis operators and cardiac surgery centres closed capacity, and two listed hospital groups restructured their debt.\n\nBy late 2034 the question put to health ministers had changed. It was no longer whether the treatment worked or what it cost. It was why a neighbouring nation with a lower income had cut its stroke admissions by a fifth while their own had not moved."

      "text": "The first cluster of severe respiratory illness was reported by a provincial hospital on 9 March 2031. The genome was uploaded to the shared sequence database four days later and matched no known human pathogen. Under the protocol agreed in advance, the notice went at the same time to international health authorities, regional disease control agencies and 31 contracted manufacturing sites on six continents. Vaccine candidates on two platforms were designed within a week. Validated diagnostic tests reached reference laboratories in 140 nations by day 27. Trial networks that had been funded between outbreaks enrolled their first volunteers in week three. Wastewater sampling showed the pathogen in 14 countries by week six, and those results set the order in which first doses were allocated. Regulators in the participating nations reviewed a single rolling dossier, and the first authorisation was granted on day 96. Manufacturing had started at risk before authorisation. By the end of month six, regional plants had supplied enough doses for health workers, older adults and other priority groups in every participating nation, about 1.4 billion people. No participating government restricted exports, because no single producer supplied more than a fifth of the total. An existing antiviral, repurposed in the first month, reduced admissions among those treated early. The outbreak was not prevented. About 6 per cent of the population of participating nations was infected in the first year, and staffed hospital demand peaked at about 80 per cent of surge capacity in the cities affected first. Elective care was postponed for several weeks in those cities. Schools closed for two to three weeks in fewer than 20 jurisdictions. No participating nation ordered a general lockdown, and borders stayed open with testing at departure. Forecasts of the loss to world output, made in April 2031 at more than 3 per cent, were revised by December to less than half of one per cent. Outcomes differed between nations, and the differences followed capability. Some participating nations received doses on schedule but lacked the vaccinators and cold chain to deliver them outside the main cities, and coverage of priority groups there was below 40 per cent at six months. In others, supply and delivery were adequate but uptake stayed near half of eligible adults, after organised campaigns alleged that the vaccine had been approved without proper testing. Hospitals in those places exceeded capacity for several weeks. States outside the network fared worst. Those that had not shared samples or joined the allocation arrangement received authorised doses four to six months later, and several imposed prolonged movement restrictions in the interval. Suppliers that had expected scarcity pricing sold at the pre-agreed price, and producers of protective equipment were left with unsold stock. The reviews published in 2032 recorded that vaccine design had taken days and that nearly all the remaining time had gone on trials, regulatory coordination, batch release and delivery. They also recorded that consent and public trust had determined outcomes as much as supply had."
