The International Monetary Fund (IMF) has warned that a sharp reversal in artificial intelligence investment, prolonged conflict in the Middle East and mounting government debt could undermine global economic growth and financial stability.
In its latest World Economic Outlook, released on Tuesday, October 13, 2026, the IMF projected global economic growth of 3.1 per cent in 2026, slightly above its previous forecast of 3 per cent. Strong investment in AI infrastructure has helped offset the economic impact of elevated oil prices and geopolitical tensions.
The fund expects global growth to reach 3.4 per cent in 2027, provided shipping routes in the Middle East return to normal and energy market disruptions ease.
However, the outlook could deteriorate if the conflict continues to push oil prices higher. In one adverse scenario, oil prices remaining above $130 per barrel through the first quarter of 2027 could reduce global growth by 0.5 percentage points.
The IMF also warned that disappointing returns from AI investments could trigger a sharp decline in technology valuations, weaken business investment and reduce consumer spending. Under a severe scenario, an AI investment downturn could lower global gross domestic product by 1.1 per cent by 2028, with US economic output falling by 1.8 per cent.
Rising public debt presents another major challenge, particularly for countries facing high borrowing costs and limited fiscal room to respond to economic shocks.
The IMF urged governments to strengthen public finances, manage financial risks and avoid excessive reliance on continued AI-driven market growth.
The warnings highlight the uncertainty surrounding an economic outlook increasingly dependent on technology investment, stable energy supplies and sustainable government borrowing.
