WASHINGTON — The outlooks for the U.S. and global economies have significantly worsened in the wake of President Donald Trump’s tariffs and the uncertainty they have created, the International Monetary Fund said Tuesday.

The IMF said that the global economy will grow just 2.8% this year, down from its forecast in January of 3.3%, according to its latest World Economic Outlook. And in 2026, global growth will be 3%, the fund predicts, also below its previous 3.3% estimate.

U.S. economic growth will come in at just 1.8% this year, down sharply from its previous forecast of 2.7% and a full percentage point below its 2024 expansion. The IMF doesn’t expect a U.S. recession, though it has raised its odds of one this year from 25% to 37%.

The forecasts are largely in line with many private-sector economists’ expectations, though some do fear a recession is increasingly likely. Economists at JPMorgan say the chances of a U.S. recession are now 60%. The Federal Reserve has also forecast that growth will weaken this year, to 1.7%.

“We are entering a new era,” Pierre-Olivier Gourinchas, chief economist at the IMF, said. “This global economic system that has operated for the last eighty years is being reset.”

The IMF is a 191-nation lending organization that works to promote economic growth and financial stability and to reduce global poverty.

Gourinchas said that the heightened uncertainty around the import taxes led the IMF to take the unusual step of preparing several different scenarios for future growth. Its forecasts were finalized April 4, after the Trump administration announced sweeping tariffs on nearly 60 countries along with nearly-universal 10% duties.

Those duties were paused April 9 for 90 days. Gourinchas said the pause didn’t substantially change the IMF’s forecasts because the U.S. and China have imposed such steep tariffs on each other since then.

The uncertainty surrounding the Trump administration’s next moves will also likely weigh heavily on the U.S. and global economies, the IMF said. Companies may pull back on investment and expansion as they wait to see how the trade policies play out, which can slow growth.

China is also forecast to grow more slowly because of U.S. tariffs. The IMF now expects it will expand 4% this year and next, down roughly half a point from its previous forecasts.

While the U.S. economy will likely suffer a “supply shock,” similar to what hampered during the pandemic and which pushed up inflation in 2021 and 2022, Gourinchas said, China is expected to experience reduced demand as U.S. purchases of its exports fall.

Inflation will likely worsen in the United States, rising to about 3% by the end of this year, while it will be little changed in China, the IMF forecast.

The European Union is forecast to grow more slowly, but the hit from tariffs is not as large, in part because it is facing lower U.S. duties than China. In addition, some of the hit from tariffs will be offset by stronger government spending by Germany.

The economies of the 27 countries that use the euro are forecast to expand 0.8% this year and 1.2% next year, down just 0.2% in both years from the IMF’s January forecast.

Japan’s growth forecast has been marked down to 0.6% this year and next, 0.5% and 0.2% lower than in January, respectively.
