The International Monetary Fund (IMF) has cautioned governments worldwide against increasing public borrowing and spending amid rising debt servicing costs, which are reaching levels not seen in decades. Speaking at the IMF’s annual meeting in Bangkok, Thailand, senior officials urged member countries to exercise fiscal restraint to avoid exacerbating the financial burden on taxpayers.

Era Dabla-Norris, deputy director of the IMF fiscal affairs department, highlighted the upward pressure on bond yields caused by expectations of large future bond issuance. She described rising government interest payments as an “inflexible burden” that could crowd out essential spending in social services, healthcare, and education. The IMF projects that the United States’ debt interest payments will more than double, growing from 2.3 percent of GDP in 2021 to 5.7 percent by the early 2030s, an amount roughly equivalent to projected social security expenditures.

Benchmark yields on ten-year US Treasury bonds have climbed from 4.1 percent at the start of the year to 5.1 percent and could reach 6 percent for the first time since 2000, according to forecasts by Pimco, a global asset management firm. A survey by Bank of America suggests that reaching this yield level could prompt investors to shift funds from equities to government bonds. On a global scale, the IMF estimates that debt interest costs will increase from 2.3 percent of GDP in 2021 to 3.7 percent by 2031.

In the United Kingdom, debt interest payments have exceeded £100 billion annually over the past four years, making these costs the largest spending item outside the National Health Service. The IMF warned that governments relying heavily on shorter-term bonds risk accelerating the impact of rising central bank policy rates on borrowing costs, a concern particularly relevant amid ongoing inflationary pressures and higher energy prices.

Despite these challenges, the IMF does not characterize the recent sell-off in bond markets as a crisis. Athanasios Vamvakidis, deputy director of the IMF’s monetary and capital markets department, noted that the sovereign debt market continues to function with adequate liquidity, describing current conditions as a return to pre-2008 financial crisis norms. He attributed the bond sell-off primarily to external factors such as increased oil prices and inflation, rather than fiscal policy decisions, while suggesting that renewed market discipline could incentivize governments to improve their fiscal situations.

In Europe, observers have raised concerns about the widening spreads between French government bonds and those of neighboring countries. Political uncertainty ahead of France’s presidential election next year may complicate government efforts to reduce the nation’s high deficit, and there is speculation that the European Central Bank may intervene to stabilize markets, potentially prompting spending cuts.

The IMF also revised upward its growth forecast for the UK to 1.3 percent this year, a 0.3 percentage point increase, praising the government’s efforts to stabilize public finances. The UK's relatively strong economic performance in the first half of the year, despite inflation and higher energy costs, offers some optimism ahead of Chancellor John Healey’s first budget set for October 28, which he has pledged will emphasize fiscal discipline and economic resilience.
