IMF Warns Surge in U.S., China Debt Could Have ‘Profound’ Impact on Global Economy

The U.S. and Chinese governments should take action to lower future borrowing, as a surge in their debts threatens to have “profound” effects on the global economy and the interest rates paid by other countries, the International Monetary Fund said Wednesday.

In its twice-yearly report on government borrowing, the Fund said many rich countries have adopted measures that will lead to a reduction in their debts relative to the size of their economies, although not to the levels seen before the Covid-19 pandemic.

However, that is not true of the U.S. and China, which will continue to see a surge in borrowing if current policies remain in place. The Fund projected that U.S. government debt relative to economic output will rise by 70% by 2053, while Chinese debt will more than double by the same year.

The Fund said both countries will lead a rise in global government debt to 98.8% of economic output in 2029 from 93.2% in 2023. The U.K. and Italy are among the other big contributors to that increase.

“The increase will be led by some large economies, for example, China, Italy, the United Kingdom, and the United States, which critically need to take policy action to address fundamental imbalances between spending and revenues,” the IMF said.

The IMF expects U.S. government debt to be 133.9% of annual gross domestic product in 2029, up from 122.1% in 2023. And it expects China’s debt to rise to 110.1% of GDP by the same year from 83.6%.

The Fund said there had been “large fiscal slippages” in the U.S. during 2023, with government spending exceeding revenues by 8.8% of GDP, up from 4.1% in the previous year. It expects the budget deficit to exceed 6% over the medium term.

That level of borrowing is slowing progress toward reducing inflation, the Fund said, and may also increase the interest rates paid by other governments.

“Loose US fiscal policy could make the last mile of disinflation harder to achieve while exacerbating the debt burden,” the Fund said. “Further, global interest rate spillovers could contribute to tighter financial conditions, increasing risks elsewhere.”

A series of weak auctions for U.S. Treasurys are stoking investors’ concerns that markets will struggle to absorb an incoming rush of government debt. The government is poised to sell another $386 billion or so of bonds in May—an onslaught that Wall Street expects to continue no matter who wins November’s presidential election.

While analysts don’t expect those sales to fail, a sharp rise in U.S. bond yields would likely have consequences for borrowers around the world. The IMF estimated that a rise of one percentage point in U.S. yields leads to a matching rise for developing economies and an increase of 90 basis points in other rich countries.

“Long-term government bond yields in the United States remain elevated and sensitive to inflation developments and monetary policy decisions,” the Fund said. “This could lead to volatile financing conditions in other economies.”

China’s budget deficit fell to 7.1% of GDP in 2023 from 7.5% the previous year, but the IMF projects a steady pickup from this year to 7.9% in 2029. It warned that a slowdown in the world’s second largest economy “exacerbated by unintended fiscal tightening” would likely weaken growth elsewhere, and reduce aid flows that have become a significant source of funding for governments in Africa and Latin America.

An unusually large number of elections is likely to push government borrowing higher this year, the Fund said. It estimates that 88 economies or economic areas are set for significant votes, and that budget deficits tend to be 0.3% of GDP higher in election years than in other years.

“What makes this year different is not only the confluence of elections, but the fact that they will happen amid higher demand for public spending,” the Fund said. “The bias toward higher spending is shared across the political spectrum, indicating substantial challenges in gathering support for consolidation in the years ahead, and particularly in a key election year like 2024.”

Former New Hampshire Gov. Chris Sununu delivered a warning to Treasury Secretary Scott Bessent during a recent visit to Washington: Already-high airfares will surge if the war in Iran doesn’t end soon.

Sununu, a Republican who represents some of the biggest airlines as president of the industry group Airlines for America, has for weeks sounded the alarm to Trump administration officials about the economic fallout from high jet fuel prices. The war, Sununu has argued, must come to a close soon, or things will get worse.

Administration officials have gotten the message.

Privately, President Trump’s advisers are increasingly worried that Republicans will pay a political price for the rising fuel costs, according to people familiar with the matter. Many of those advisers are eager to end the war, hoping prices will begin to moderate before November’s midterm elections.

The fallout from the U.S.-Israeli attack in late February has slowed traffic through the Strait of Hormuz, a vital shipping lane, triggering a sharp increase in oil, gasoline and jet-fuel prices.

That means consumers are grappling with high costs ahead of the summer travel season, as they consider vacation plans.

Sixty-three per cent of Americans said they put a great deal or a good amount of blame on Trump for the increase in gas prices, according to a new poll conducted by NPR, PBS and Marist.

More than 8 in 10 Americans said struggles at the gas pump are putting strain on their finances.

Jet-fuel prices roughly doubled in a matter of weeks after the war began, and they have remained high. Airlines have said that will add billions of dollars of additional expenses this year, squeezing profit margins.

U.S. airlines spent more than $5 billion on fuel in March—up 30% from a year earlier, according to government data.

Carriers have been raising ticket prices, hoping to pass the cost along to consumers, and they are culling flights that will no longer make money at higher price levels.

In March, the price of a U.S. domestic round-trip economy ticket rose 21% from a year earlier to $570, according to Airlines Reporting Corp., which tracks travel-agency sales.

So far, airlines have said the higher fares haven’t deterred bookings and they are hoping to recoup more of the fuel-cost increases as the year goes on.

Earlier this week, Trump said the current price of oil is “a very small price to pay for getting rid of a nuclear weapon from people that are really mentally deranged.”

Secretary of State Marco Rubio told reporters that if Iran got a nuclear weapon, the country would have more leverage to keep the strait closed and “make our gas prices like $9 a gallon or $8 a gallon.”

Trump has taken steps in recent days to bring the war to an end. Late Tuesday, the president paused a plan to help guide trapped commercial ships out of the Strait of Hormuz, expressing optimism that a deal could be reached with Iran to end the conflict.

Crude oil prices fell below $100 a barrel on Wednesday, after reports that Iran and the U.S. are working with mediators on a one-page framework to restart negotiations aimed at ending the conflict and opening the strait.

Sununu said Trump administration officials are conscious of the economic fallout from the war: “They get it…and I think that’s why they’re trying to get through the war as fast as they can.”

But he cautioned that it could take months for prices to return to prewar levels.

“Ticket prices won’t go down immediately” after the strait is fully reopened, Sununu said. “You’re looking at elevated ticket prices through the summer and fall because it takes a while for the prices to go down.”

Since the initial U.S.-Israeli attack in late February, Sununu has met in Washington with National Economic Council Director Kevin Hassett, representatives from the Transportation Department and senior White House officials.

A White House official confirmed that Hassett and Sununu have discussed the effect of increased fuel prices on the airline industry. The official said the conversation touched on how the industry can mitigate the impact of high jet fuel prices on consumers.

“The president and his entire energy team anticipated these short-term disruptions to the global energy markets from Operation Epic Fury and had a plan prepared to mitigate these disruptions,” White House spokeswoman Taylor Rogers said, pointing to the administration’s decision to waive a century-old shipping law in a bid to lower the cost of moving oil.

Rogers said the administration is working with industry representatives to “address their concerns, explore potential actions, and inform the president’s policy decisions.”

A Treasury Department spokesman pointed to Bessent’s recent comments on Fox News that the U.S. economy remains strong despite price increases. The spokesman said Treasury officials have met with airline executives, who have reaffirmed strong ticket bookings.

“We’re cognizant that this short-term move up in prices is affecting the American people, but I am also confident, on the other side of this, prices will come down very quickly,” Bessent told Fox News on Monday.

The war has already contributed to one casualty in the industry: Spirit Airlines. Company representatives have said they were forced to close the airline because the sustained surge in jet-fuel prices derailed the company’s plan to emerge from chapter 11 bankruptcy.

The Trump administration and Spirit failed to come to an agreement for the company to receive a financial lifeline of as much as $500 million from the federal government.

Transportation Secretary Sean Duffy has argued that the Iran war wasn’t the cause of Spirit’s demise, pointing to the company’s past financial struggles, as well as the Biden administration’s decision to challenge a merger with JetBlue.

Other budget airlines have also turned to the federal government for help since the U.S.-Israeli attack. A group of budget airlines last month sought $2.5 billion in financial assistance to offset higher fuel costs, and they separately wrote to lawmakers asking for relief from certain ticket taxes.

Says U.S. and China, which will continue to see a surge in borrowing if current policies remain in place.

Administration officials have spoken to the airline industry, which has voiced concerns about the rising costs.
