Scenarios 2027 / Scenarios
Rated at Standard Severe. Likelihood type: systemic. Source of scores: ginc-desk-v0.3. Upside scenario: impact levels measure the scale of change, not loss.
The communiqué runs to nine pages and the annexes to four hundred. Tariffs on both sides return to their 2017 levels over three years. The licence regimes for rare earths and for most chips are replaced by a shared list. A hotline between the two militaries is staffed around the clock, and inspectors from each side sit in the other's AI evaluation centres. Three months later the guns stop along a line in eastern Ukraine that neither capital calls a border. Freight rates fall by a third. War-risk premiums in the Black Sea and the Gulf go back to what underwriters call boring. Europe's finance ministers, who had pencilled in defence at 3.5 per cent of GDP, quietly revise the line. The complaints begin at once. A battery plant in Ohio and a chip packaging plant in Penang were financed on tariffs that no longer exist. Vietnam and Mexico, which grew rich as the detour, watch orders go back to the direct route. Taipei, Kyiv and Warsaw study the annexes for what was promised about them without them. The defence contractors guide earnings down. The countries that gain most are the ones that had kept trading with both sides and built nothing that needed the confrontation to survive.
The dateline is illustrative, not a forecast. The narrative is hypothetical; the historical anchors below are real events.
The United States and China reach a settlement that rolls back most tariffs and export controls, sets rules for AI and chips and lowers the temperature over Taiwan. A ceasefire in Ukraine becomes a signed agreement with sanctions relief in stages. Trade volumes recover, shipping and insurance costs fall and defence budgets stop rising. The peace dividend is real and uneven: industries built behind tariff walls lose protection, middle powers lose the leverage of being courted, and allies discover which of their interests were bargained away.
A shock most would count as progress. It is not upside for everyone: each record names who gains and who loses. Impact levels measure the scale of change, in either direction, and loads mark the capabilities a nation needs in order to capture the gain or absorb the loss.
| Event | Date | What happened | Calibrates |
|---|---|---|---|
| Nixon's visit to China | February 1972 | Opened relations after two decades of hostility; the Shanghai Communiqué set the Taiwan question aside | settlement by leaders; allies surprised |
| INF Treaty | December 1987 | The United States and the Soviet Union eliminated a class of nuclear missiles, with on-site inspection | verification |
| End of the Cold War | 1989–1991 | US defence spending fell from about 6 per cent of GDP in the late 1980s to about 3 per cent by 2000 | scale of a peace dividend |
| China's WTO accession | December 2001 | Tariff cuts and legal certainty; China's goods exports grew more than fivefold in the following decade | trade response to reopening; adjustment costs for importers |
| US–China leaders' meeting | 30 October 2025 | A truce: China's extraterritorial rare earth regime was suspended for a year | first step |
| Xi state visit to Washington | 23–25 September 2026 | Truce extended to 10 January 2027; a Board of Trade to identify tariff cuts; an AI safety notification mechanism; core disputes left unresolved | distance from Standard Severe |
| Ukraine peace talks | 2026 | US-mediated talks set a June target, then stalled in March as Washington's attention moved to Iran | counter-anchor on likelihood |

From the GINC 250: trends rated Very high or Critical for this scenario. All S18 trend scores.
| Rating | Band or level | Why |
|---|---|---|
| Likelihood, two years | 3Possible | Washington and Beijing held a state visit in September 2026, extended their trade truce to January 2027 and agreed an AI safety notification mechanism, but left tariffs, rare earths, chips and Taiwan unresolved. Ukraine talks stalled in March 2026. |
| Likelihood, ten years | 4Likely | Long rivalries have ended in negotiated settlements before, usually after a crisis. |
| Systemic impact | 3Significant | Level 3 as a gain: the reverse of the trade and energy shocks in S01 and S09, on a slower path. |
| National impact | 4Major | Level 4 for states whose security or leverage is traded in the settlement. |
| Confidence | low | Settlements depend on a few leaders and can reverse quickly. |
