03Narrative

Dateline: October 2028

The third tariff round lands on a Tuesday and by Friday the shipping lines have repriced every contract into the Pacific. Export licences for lithography equipment, rare earth magnets, cloud compute and gene sequencers now need sign-off on both sides, and sign-off is political. Secondary sanctions reach banks in Jakarta, Lagos and São Paulo that cleared transactions for the wrong counterparties; two of them lose dollar correspondent accounts in a week. Treasury officials in middle powers run the same spreadsheet: which bloc buys more of what we sell, which one owns the standards our factories run on, and which one holds our reserves. Ministers announce 'balanced alignment' and are punished by both sides for it. Customs systems that were built for tariff codes now carry origin audits, end-user certificates and dual-use attestations; clearance times double. Inflation runs a point and a half above target in the aligned economies and three points above in the countries that import from both blocs. The IMF's October outlook cuts world trade growth for the third year running and uses the word 'fragmentation' 41 times.

The dateline is illustrative, not a forecast. The narrative is hypothetical; the historical anchors below are real events.

04Summary

Tariffs, export controls, investment screening and sanctions escalate between the two largest economies until the trading system splits into aligned blocs. Third countries are forced to choose suppliers, standards and payment rails. World trade volumes fall by a fifth and the price of neutrality rises every quarter. This is the WEF Global Risks Report 2026's top risk on every horizon to 2028.

07Transmission channels

  1. Tariffs and controls raise input costs and cut export volumes.
  2. Third-country firms lose access to one bloc's components or markets.
  3. Secondary sanctions disrupt correspondent banking and payments.
  4. Investment screening blocks capital flows and acquisitions.
  5. Standards diverge, raising compliance cost and stranding equipment.
  6. Diplomatic alignment is priced into trade and finance terms.

08Capability loading

High: capability band shifts expected under current plans. Medium: band shifts under 'none' policy response only. Low: strain without band shift. Loads are judgement-based until the Atlas connects. Domains link to the Atlas.

14Open questions

Contested assumptions for the panel to resolve.

  • Whether services and finance belong in Standard Severe or only Extreme.
  • How to score nations that benefit from diversion.
  • Whether 'alignment pressure' is a capability load or a trend.
