U.S. stocks careened through a manic Monday after President Donald Trump threatened to crank his tariffs higher, despite a stunning display showing how dearly Wall Street wants him to do the opposite.

The S&P 500 slipped 0.2% at the end of a day full of heart-racing reversals as battered financial markets try to figure out what Trump’s ultimate goal is for his trade war. If it’s to get other countries to agree to trade deals, he could lower his tariffs and avoid a possible recession. But if it’s to remake the economy and stick with tariffs for the long haul, stock prices may need to fall further.

The Dow Jones Industrial Average fell 349 points, or 0.9%, and the Nasdaq composite edged up by 0.1%.

All three indexes started the day sharply lower, and the Dow plunged as many as 1,700 points following even worse losses elsewhere in the world. But it suddenly surged to a gain of nearly 900 points in the late morning. The S&P 500, meanwhile, went from a loss of 4.7% to a leap of 3.4%, which would have been its biggest jump in years.

The sudden rise followed a false rumor that Trump was considering a 90-day pause on his tariffs, one that a White House account on X quickly labeled as “fake news.” That a rumor could move trillions of dollars’ worth of investments shows how much investors are hoping to see signs that Trump may let up on tariffs.

Stocks quickly turned back down, and shortly afterward, Trump dug in further and said he may raise tariffs more against China after the world’s second-largest economy retaliated last week with its own set of tariffs on U.S. products.

It’s a slap in the face to Wall Street because it suggests Trump may not care how much pain he inflicts on the market. Many professional investors had long thought that a president who used to crow about records reached under his watch would pull back on policies if they sent the Dow reeling.

All that seemed certain Monday was the financial pain hammering investments around the world for a third day after Trump announced tariffs in his “Liberation Day.”

Stocks in Hong Kong plunged 13.2% for their worst day since 1997. A barrel of benchmark U.S. crude oil dipped below $60 during the morning for the first time since 2021, hurt by worries that a global economy weakened by trade barriers will burn less fuel. Bitcoin sank below $79,000, down from its record above $100,000 set in January, after holding steadier than other markets last week.

“The recent tariffs will likely increase inflation and are causing many to consider a greater probability of a recession,” JPMorgan CEO Jamie Dimon, one of the most influential executives on Wall Street, wrote in his annual letter to shareholders Monday. “Whether or not the menu of tariffs causes a recession remains in question, but it will slow down growth.”

In the bond market, Treasury yields recovered some of their sharp drops from earlier weeks. The yield on the 10-year Treasury jumped to 4.20% from 4.01% late Friday.

Earlier in the day, the S&P 500 briefly fell more than 20% below its record set less than two months ago. If it finishes a day below that bar, it would be a big enough drop that Wall Street has a name for it. A “bear market” signifies a downturn that’s moved beyond a run-of-the-mill 10% drop, which happens every year or so, and has graduated into something more vicious.

The S&P 500, which sits at the heart of many investors’ 401(k) accounts, is coming off its worst week since COVID-19 began crashing the global economy in March 2020.

All told, the index fell 11.83 points Monday to 5,062.25. The Dow Jones Industrial Average dropped 349.26 to 37,965.60, and the Nasdaq composite added 15.48 to 15,603.26.
