A sharp sell-off in U.S. government bond markets has sparked fears about the growing fallout from President Trump’s sweeping tariffs and retaliation by China, the European Union and others, raising questions about what is typically seen as the safest corner for investors to take cover during times of turmoil.
Yields on 10-year Treasuries — the benchmark for a wide variety of debt — shot 0.2 percentage points higher on Wednesday, to 4.45 percent, a big move in that market. Just a few days ago, it had traded below 4 percent. Yields on the 30-year bond rose significantly as well, at one point on Wednesday topping 5 percent. Borrowing costs globally have also shot higher.
The sell-off comes as investors have fled riskier assets globally in what some fear has parallels to what became known as the “dash for cash” episode during the pandemic, when the Treasury market broke down. The recent moves have upended a longstanding relationship in which the U.S. government bond market serves as a safe harbor during times of stress.
Volatility has surged as stock markets have plummeted amid fears that the U.S. economy is hurtling toward stagflation, in which economic growth contracts while inflation surges. The S&P 500 is now on the verge of entering a bear market, meaning it has dropped 20 percent from its recent high.
“The global safe-haven status is in question,” said Priya Misra, a portfolio manager at JPMorgan Asset Management. “Disorderly moves have happened this week because there is no safe place to hide.”
Scott Bessent, the U.S. Treasury secretary, sought to tamp down concerns on Wednesday, brushing off the sell-off as nothing more than investors who bought assets with borrowed money having to cover their losses.
“I believe that there is nothing systemic about this — I think that it is an uncomfortable but normal deleveraging that’s going on in the bond market,” he said in an interview with Fox Business.
But the moves have been significant enough to raise broader concerns about how foreign investors now perceive United States, after Mr. Trump decided to slap onerous tariffs on nearly all of its trading partners. Some countries have sought to strike deals with the administration to lower their tariff rates. But China retaliated on Wednesday, announcing an 84 percent levy on U.S. goods after Mr. Trump raised the tariff rate on Chinese goods to 104 percent.
In a social media post on Wednesday, the former U.S. Treasury secretary Lawrence H. Summers said the broader sell-off suggested a “generalized aversion to US assets in global financial markets” and warned about the possibility of a “serious financial crisis wholly induced by US government tariff policy.”
“We are being treated by global financial markets like a problematic emerging market,” he wrote.
