03Narrative

Dateline: August 2027

The auction fails on a Thursday. By Monday the currency has lost 30 per cent, fuel importers cannot open letters of credit and the central bank has 11 days of import cover left. The finance ministry's contingency plan assumes a swap line that the partner central bank declines to extend. Queues form at petrol stations, then at pharmacies, then at the ports where ships wait for payment before unloading grain. Public-sector salaries are paid late, then in part. The government requests an IMF programme and discovers that the restructuring requires creditors who do not sit in the same room. A second variant plays elsewhere: a mid-sized economy wakes to find its reserves frozen by a coalition of central banks and its banks cut from messaging systems; the import economy stalls within a fortnight. A third: a low-income state learns that the donor financing a third of its health budget has suspended disbursements, and the drug supply chain breaks before the budget year ends.

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

04Summary

A nation loses the ability to fund itself: market access closes, the currency collapses, reserves are exhausted or frozen, or external aid is withdrawn. The IMF's Debt Sustainability Frameworks already specify standardised stress tests for this; the scenario adapts them to capability. Three variants: market loss (Sri Lanka 2022), sanctions and reserve freeze (Russia 2022) and aid withdrawal (the 2025 US foreign-aid freeze for aid-dependent states). An advanced-economy variant exists (the UK gilt crisis of September 2022).

14Open questions

Contested assumptions for the panel to resolve.

  • Whether the advanced-economy variant should be a separate scenario.
  • How to score nations inside currency unions.
  • Whether aid withdrawal is a shock or a trend after 2025.
