Global government debt is headed to 99% of world GDP by 2028, and the International Monetary Fund warned on Wednesday that the burden could surge to 121% within three years if the world slips into stress scenarios that sit at the 95th percentile of plausible outcomes.
Rodrigo Valdez opened the spring launch of the IMF’s biannual Fiscal Monitor with a blunt warning: public finances are being tested again as the war in the Middle East pushes up fuel and food prices and forces governments to respond. “The world economy is being tested again with the consequences of the war in the Middle East—and this is a world that has less degrees of freedom as public finances are more stretched in many, many countries,” he said.
The weight of the warning is clearest in the United States, where the IMF said debt is now on track to exceed 125% of GDP this year and could reach 142% by 2031. The U.S. deficit narrowed last year from close to 8% to below 7% of GDP, but Valdez said the forecast still points to a deficit of around 7.5% for the near future, adding, “That is not minor, of course.”
The IMF’s case is that this is no longer only a cyclical problem. Valdez said the fiscal gap has worsened by roughly one percentage point compared with the five years before COVID, while real interest rates are now running some 6 percentage points above pre-pandemic levels. He said the premium U.S. Treasuries once commanded over other advanced-economy debt is narrowing, a sign that markets are less willing to look past rising borrowing than they once were.
That shift matters because the IMF said the fiscal tightening needed just to stabilize the U.S. debt path would amount to roughly 4 percentage points of GDP. Valdez said, “The more time passes, the more pressure you could face down the road,” and warned, “This cannot wait forever.”
The fund also pointed to the policy choices behind the problem. Valdez said the debt buildup “basically reflects policy choices—permanently higher spending and lower revenues,” and argued that broad-based energy subsidies or excise reductions are not the best tool. “They distort price signals, are fiscally costly, regressive, and hard to unwind,” he said. The IMF added that domestic policies affect global prices, linking national budgets to a wider inflation and growth problem that goes well beyond Washington.
The immediate answer, then, is not that global government debt has crossed a single alarming threshold and stopped there. It is that the threshold is being approached just as borrowing costs stay high, markets grow less forgiving, and governments are still reaching for fixes that do not solve the underlying arithmetic. The IMF’s warning is that the bill is already arriving, and the longer policymakers wait, the harder it becomes to pay it without sharper cuts or higher taxes later.
