The IMF's spring meeting in Bangkok produced a paradox that deserves more scrutiny than it received. The global economy has absorbed the Iran war, supply-chain disruptions, and sky-high oil prices without a synchronized crisis — but the bill for that survival is now coming due in the form of record deficits, rising debt, and fiscal buffers that no longer exist. The resilience is real; the question is whether it was purchased on a credit card with no repayment plan. The headline number is extraordinary: governments worldwide have spent the equivalent of 0.5% of global GDP on energy support measures since the Iran conflict began. That is not a rounding error — it is a transfer from future taxpayers to present consumers, and the IMF warns many countries cannot sustain it. Some have already begun withdrawing subsidies, which means the cost of the conflict is about to land directly on households. The IMF's advice — temporary, targeted measures rather than blanket subsidies — is economically sound and politically suicidal. Advanced-economy fiscal positions have deteriorated to their worst since the depths of Covid. Budget deficits this year are projected at pandemic-era levels, and government debt in rich countries is on track to rise from 108% of GDP to 115% within five years. Kristalina Georgieva's lament that countries failed to rebuild fiscal buffers during the post-pandemic recovery is accurate but too polite: the buffers were spent on political convenience, and now there is nothing left for the next shock. Bond markets have noticed — yields are at multi-decade highs, reflecting a mix of inflation expectations and plain doubt about fiscal sustainability. The AI boom is the third leg of this unstable stool. The IMF's Global Financial Stability Review laid out the leverage, the interconnected financial linkages, and the concentration of benefits in a handful of economies — Taiwan, South Korea, and the US tech sector. Federal Reserve chair Kevin Warsh's admission that 'we really don't know what the market structure is going to be' is remarkably candid for a sitting central banker. South Korea's Kospi index fell 14.5% in a single week — its worst since the 2008 financial crisis — as investors dumped Samsung and SK Hynix. CoreWeave bonds approached distressed levels. These are not hypothetical tremors. The geopolitical backdrop made the institutional dysfunction impossible to ignore. US Treasury Secretary Scott Bessent, formally chair of the G20 finance ministers, did not attend. No communiqué was issued after the G20 meeting — a stark signal that multilateral consensus is functionally dead. UK Chancellor John Healey stepped in to chair the meeting and spent his time championing Ukraine, filling a vacuum that Washington has conspicuously abandoned. Russia's delegation was present at the G20, to the visible discomfort of UK officials. The UK received a rare positive review from the IMF for its deficit reduction plan, though Georgieva conceded that bond markets have not rewarded the effort. Her explanation — that London's status as a global financial centre attracts extra scrutiny — is diplomatic code for saying that being fiscally responsible in one country does not insulate you from global risk repricing. The UK's reward for prudence is the same borrowing cost increase as everyone else. The structural picture is clear: the global economy is running three concurrent bets simultaneously. Bet one: that the Iran conflict ends before energy subsidies bankrupt vulnerable governments. Bet two: that sovereign debt levels stabilize before bond vigilantes force a reckoning. Bet three: that AI investment produces real productivity gains before the leverage behind it unwinds. Any one of these bets failing is manageable. Two failing simultaneously would be severe. All three failing at once is the scenario the IMF is quietly warning about — and it is no longer a tail risk.
