IMF Warns Bond Yields Face Disorderly Rise Amid Debt Risks

The International Monetary Fund warned on Tuesday, October 13, 2026, in Bangkok that government bond markets face rising risks from inflation, heavy debt and AI-related borrowing, which could trigger sharp increases in yields.

The IMF's latest Global Financial Stability Report said advanced economies have seen bond yields reach multidecade highs as energy costs and expectations for tighter monetary policy increase pressure on markets.

According to the IMF, high debt levels and refinancing risks have made sovereign bond markets more vulnerable to fiscal and inflation shocks. Global public debt is nearing its highest level since World War II and is expected to exceed 100% of GDP.

"Impact could be severe given the foundational importance of sovereign bond markets," the IMF said.

The report also highlighted the rapid expansion of AI-related borrowing, with hyperscalers accounting for 10% of global investment-grade bond issuance, up from less than 1% since 2024.

"AI-linked issuance – much of it longer-dated – has grown large enough to compete with government bonds for investor capital, even if it does not appear to be the dominant driver of yields," said Marc Seidner, CIO of non-traditional strategies at Pacific Investment Management.

The IMF said hedge funds' growing exposure to US Treasuries could add pressure during a market reversal. Their share of Treasury holdings increased to about 9% in 2025 from about 4% in 2022, according to Federal Reserve data cited by the fund.

"If there are questions about the monetization in 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," said Jason Wu, assistant director of the IMF monetary and capital markets department.

Wu said AI financing structures could create concentrated risks among several firms. The IMF reported 14 publicly disclosed deals since 2023 involved about $300 billion in equity and $650 billion in debt, alongside $1.4 trillion in future revenue commitments.

"There are certain companies and nodes that are particularly exposed," said Jason Wu, assistant director of the IMF monetary and capital markets department.

"If there are some kind of issues with those entities, then the circularity would pose risk to the market," said Jason Wu, assistant director of the IMF monetary and capital markets department.

The IMF also warned the broader global economy could face additional pressure from depleted energy reserves, geopolitical tensions and limited government capacity to respond to future shocks.

"Without shoring up supply capacity and replenishing policy buffers, the global economy could soon test the limits of resilience," the IMF said.

Silvana Tenreyro, the IMF's economic counsellor, said the global economy had absorbed recent shocks but required stronger policy preparation.

"The global economy has been resilient, but that resilience is reaching its limits," said Silvana Tenreyro, IMF economic counsellor.

Kristalina Georgieva, IMF managing director, urged governments to address rising debt pressures as finance officials gathered for the IMF and World Bank annual meetings in Bangkok.

"We cannot keep delaying necessary policy action – you have the tools, now have the wisdom to use them," said Kristalina Georgieva, IMF managing director.

The IMF projected global growth at 3.1% in 2026 and 3.4% in 2027, while warning that higher energy prices and interest rates could weigh on future economic activity.
