The International Monetary Fund published its Global Financial Stability Report on 13 October 2026. TSN could not open the report on imf.org, so the figures and quotes below are as reported by Reuters, with the Guardian as a second source.
The IMF has warned against “complacency” in global financial markets, Reuters reports. In its twice-yearly Global Financial Stability Report, it says an AI-driven selloff, a spike in government bond yields or a major cyberattack are among “plausible near-term catalysts” for trouble that policymakers should watch [1].
The Guardian quotes the full phrase as “plausible near-term catalysts for a sharp tightening of financial conditions and market turmoil” [2].
The AI risk
According to Reuters, the IMF says AI investment has so far helped offset the drag on the economy from the war in the Middle East and from policy uncertainty. But it sees “growing evidence” that AI may not need as much investment as is being spent, or that the economic gains may not be as large as expected [1].
“An AI market correction will affect the real economy,” Athanasios Vamvakidis, deputy director in the IMF’s Monetary and Capital Markets Department, told a press briefing in Bangkok. Markets look strong, he said, but such “resilience is not necessarily safety” [1].
Borrowing is part of the worry. If AI investment slows, rising debt in the sector could make a shock worse by forcing investors to sell. Reuters reports the IMF’s example: hyperscalers, the big companies building AI data centres, “now represent 10% of global investment-grade bond issuance, up from less than 1% in 2024” [1].
“The consequences of an AI correction could be global,” the IMF warned, according to both Reuters and the Guardian [1][2]. It asked policymakers to curb the use of borrowed money, including derivatives and margin loans, where it is “excessive” [1].
Vamvakidis also told the Guardian’s reporters: “The exposure of the rest of the world to US assets, particularly AI, is the highest it has ever been” [2].
Bond yields
The IMF said bond market risks have got worse since April, Reuters reports, as higher energy prices pushed up government bond yields, on top of high government debt [1].
“The market is concerned about absorption potential of the huge issuance that is coming from the sovereigns and increasingly also from the private sector, at the time that central banks are shrinking their balances,” Vamvakidis said. In plain terms: governments and companies are selling a lot of bonds just as central banks stop buying them [1].
Cyberattacks
“In over 70% of cases so far in 2026, software providers have had almost no time to patch vulnerabilities before they were exploited, a 20 percentage point jump from a year ago,” the IMF said, according to Reuters. It added that AI models are making attacks more sophisticated, and called for stricter oversight of outside technology suppliers [1].
Banks
The IMF’s stress test found banks’ capital cushions stay robust even in a downturn caused by an AI slowdown and bond market strain. But it found “pockets of weakness”: banks holding 22% of global banking assets had “weak” capital levels under the test, up from 18% in the 2025 test [1].
A separate report: the World Economic Outlook
The IMF also published its World Economic Outlook on the same day. This is a different report. In one downside scenario, Reuters reports, a steep fall in AI investment could cause a sharp drop in asset prices, “ultimately cutting global GDP by 1.1% by 2028, including a 1.8% drop in US output” [3].
“If there are questions about the monetization of AI, the equity investments will deplete in value, the debt may be difficult to service, and the revenue commitments in the future may not materialize,” Jason Wu, assistant director of the IMF’s Global Markets Analysis Division, told a press conference in Bangkok [3].
What this means
- The IMF is not predicting a crash. It is naming three things that could set one off: an AI correction, a bond yield spike and a big cyberattack.
- AI borrowing is now big enough to matter. The hyperscalers’ share of investment-grade bond sales has jumped, Reuters reports.
- Most banks look strong, but fewer than last year. The share of banking assets in “weak” banks rose from 18% to 22%.
