The warning came in the fund's twice-yearly World Economic Outlook, published on Tuesday in Bangkok, where the IMF and World Bank are holding their annual meetings with finance ministers and central bankers in attendance.
The IMF said global growth had withstood the Middle East conflict better than expected over the past six months, helped by the rerouting of oil supplies away from the Strait of Hormuz and the release of strategic energy stocks, which contained the impact of the US-Iran war on oil prices. But it cautioned that emergency inventories are now depleted, and high debt levels and deficits could leave governments with little capacity to protect consumers from any future jump in prices.
'Without shoring up supply capacity and replenishing policy buffers, the global economy could soon test the limits of resilience,' the fund said. 'Inventories in energy markets are dwindling and additional geopolitical shocks could still transmit rapidly through prices and supply disruptions.'
The International Energy Agency announced the largest-ever emergency releases of oil stocks in March and promised to accelerate them after a meeting of oil ministers last month. In a sign of the system's vulnerability, the US strategic petroleum reserve has reportedly fallen to its lowest level since 1982.
Last week, Donald Trump agreed a deal with Vladimir Putin to temporarily lift sanctions on US imports of Russian diesel in an attempt to bring down prices at the pumps, a move analysts said would have little 'meaningful' effect.
Ahead of the meetings, IMF managing director Kristalina Georgieva urged governments to tighten their belts amid rising global debt levels. 'We cannot keep delaying necessary policy action. You have the tools, now have the wisdom to use them,' she said.
The IMF revised its forecast for global growth this year up marginally to 3.1%, from 3% in July, and left next year's forecast unchanged at 3.4%. US growth is unchanged at 2.3% this year and was nudged up to 2.3% for 2027, from 2.2%.
