President Donald Trump backed down from the most extreme “Liberation Day” tariffs after bond traders revolted at the prospect of economic upheaval. Now, his push to coerce Denmark into ceding Greenland has threatened to trigger a similar market rout.

Bond yields spiked and stocks sank on Tuesday as investors reckoned with how Trump’s threat to impose new tariffs on Europe could hammer alliances that are critical to the global economy. That reignited fears that the “Sell America” trade that dominated market narratives last spring could reemerge, undercutting Wall Street’s hopes for U.S. assets in 2026.

As global leaders and top financial CEOs gathered in Davos for the World Economic Forum, where Trump is scheduled to speak on Wednesday, the blowback from bond traders threatened to undermine the president’s bullish case for both the U.S. economy and its market outlook.

“The narrative just won’t go away,” said Paul Christopher, head of global investment strategy at the Wells Fargo Investment Institute. Foreign investors flooded back into U.S. assets as tensions eased during the latter half of 2025, but now “they’re hedging because they’re not sure what Trump is going to do with tariffs next.”

Trump has historically been highly sensitive to how the bond market responds to his policies, and he regularly cites the stock market’s surge as evidence of how his agenda is working. The latest turmoil has echoes of the volatility that hit global bond markets shortly after he announced eye-popping tariffs last April on dozens of trading partners at a White House press conference. The president later announced a temporary pause on the new import duties after the bond market started “getting a little bit yippy,” in his words.

His threat on Saturday to impose more tariffs on Europe sparked a similar response. The Dow Jones Industrial Average fell by more than 870 points on Tuesday. The Nasdaq and S&P 500 both closed down by more than 2 percent — erasing the gains notched through the first three weeks of the year. Yields on the 10-year and 30-year Treasury securities — which are benchmark rates for consumer and corporate lending products — jumped to their highest levels since last September, and the dollar sank.

The president warned that he would impose additional 10 percent tariffs on eight European countries that have sought to block his ambitions to acquire Greenland, the sparsely populated Danish territory that’s been a fixation of the president since his first term.

French President Emmanuel Macron has said he’s planning to activate the EU’s so-called trade bazooka — the Anti-Coercion Instrument — to respond to Trump’s saber rattling. That would allow the EU to impose restrictions on investment and access to public procurement schemes, as well as limits on intellectual property protection.

The White House pushed back on the notion that the markets were rejecting Trump’s policies.

“The S&P 500 is up over 10 percent and 10-year Treasury bond yields are down nearly 30 basis points over the past year because the markets have confidence in the Trump administration’s pro-growth, pro-business policies,” White House spokesperson Kush Desai said. “Accelerating GDP growth, cooled inflation, and over a dozen historic trade deals all prove that this Administration continues to deliver for American workers and companies.”

Banking leaders — including Bank of America CEO Brian Moynihan, Citi’s Jane Fraser and State Street’s Ron O’Hanley — signaled optimism at the U.S.’s economic outlook in separate media appearances in Davos as they urged government leaders to find a resolution.

“Let the people go to work,” Moynihan told CNBC. “They’re here in this beautiful place, and they’ve got a week to a few days to work on it. So, give them 48 hours and see if they can come up with solutions.”

Throughout his first year back in the White House, Trump’s costly tariffs and insistence that Europe do more to finance its own defense have caused economic disruption and forced leaders across the continent to reckon with the possibility that the U.S. is no longer as strong a partner as it once was.

And while markets have grown increasingly confident that the president’s frequent escalations result in policies that are far less severe than his initial threats, finding an off-ramp in the fight over Greenland’s future could prove challenging.

“The market’s very complacent to the idea that this is just a negotiating tool,” said Brij Khurana, a fixed-income portfolio manager at Wellington Management. “I’m more nervous about it because I don’t, I don’t see what the middle ground is here.”

In an appearance on Fox Business from Davos on Tuesday, Treasury Secretary Scott Bessent said it’s “very difficult to disaggregate” the market’s reaction to Trump’s Greenland push from a massive sell-off in Japanese bonds that was triggered by mounting concerns about the country’s fiscal trajectory. As European leaders consider taking steps to retaliate against Trump, Bessent urged caution.

“Sit back, take a deep breath, do not retaliate,” he said. “The president will be here tomorrow, and he will get his message across.”
