The International Monetary Fund used its annual meetings in Bangkok to put a number on the AI downside. In the October World Economic Outlook released October 13, the Fund raised its 2026 global growth forecast to 3.1 percent from 3.0 percent in July, crediting still-strong AI infrastructure investment with offsetting higher oil prices from the Middle East war. But its downside scenario, in which AI investment falls steeply on disappointing productivity or profitability, cuts global GDP by 1.1 percent by 2028, including a 1.8 percent hit to United States output. The Fund stressed that even that scenario does not produce a recession.
The companion Global Financial Stability Report was blunter about markets. It warned that a correction in AI-linked equities and credit could spread beyond tech, pointing to the concentration of index value in a handful of megacaps and to circular financing arrangements in which hyperscalers invest in, lend to and sell cloud capacity to the same AI companies. If those partners cannot pay, the revenue commitments underpinning the buildout are at risk.
The warning lands in a market already repricing the hardware chain: semiconductors fell 7.73 percent over the past week in this site’s market data, and ASML’s earnings this morning were treated as a demand test for the whole complex. The IMF is not calling a top; it is saying the macroeconomy now has enough exposure to AI spending that a private-sector disappointment becomes a public growth problem. That is a different register from the Bank for International Settlements’ June caution, and it gives finance ministries a modeled loss figure, 1.1 percent of global output, to plan against.
