Wall Street slumped on Thursday and global stock markets declined after U.S. Federal Reserve Chair Jerome Powell repeated his pledge to keep credit flowing until Americans are back to work, rebutting investors who have openly doubted he can stick to that promise once the pandemic passes.
Benchmarket U.S. Treasury yields rose toward last week's highs as Powell spoke, and the dollar hit a three-month high.
Oil prices spiked to their highest in over a year as OPEC and its allies agreed to extend most oil output cuts into April, after deciding that the demand recovery from the pandemic remained fragile.
With COVID-19 vaccines rolling out and the government fiscal taps open "there is good reason to think we will make more progress soon" toward the Fed's goals of maximum employment and 2% sustained inflation, Powell told a Wall Street Journal forum.
But "even if that happens it will take substantial time," Powell added.
The Dow Jones Industrial Average fell 345.95 points, or 1.11%, to 30,924.14, the S&P 500 lost 51.25 points, or 1.34%, to 3,768.47 and the Nasdaq Composite dropped 274.28 points, or 2.11%, to 12,723.47.
"This market has already been weak and was looking for another excuse to sell," said Dennis Dick, head of markets structure and a proprietary trader at Bright Trading LLC in Las Vegas, citing fear in equities markets for the past nine months. "Now, Powell gives them that excuse as well."
The pan-European STOXX 600 index lost 0.37% and MSCI's gauge of stocks across the globe shed 1.62%, its third day of losses.
Emerging market stocks lost 2.61%. MSCI's broadest index of Asia-Pacific shares outside Japan closed 2.63% lower, while Japan's Nikkei lost 2.13% to its lowest since Feb. 5.
Worries about loftier U.S. bond yields have also hit global shares.
Powell said the increase was "notable" but he did not consider it a "disorderly" move, or one that pushed long-term rates so high the Fed might have to intervene to bring them down.
Benchmark 10-year notes last fell 21/32 in price to yield 1.5432%, from 1.47% late on Wednesday. They earlier touched their highest levels since a one-year high of 1.614% set last week on bets on a strong economic recovery aided by government stimulus and progress in vaccination programs.
The cost of borrowing U.S. Treasuries in the overnight repurchase agreement, or repo market, went negative on Thursday, analysts said, amid the bond market sell-off, which pointed to stress in money markets.

Germany's 10-year yield was down 2 basis points to -0.33% after rising 5 basis points on Wednesday.
Many Fed officials have downplayed the rise in Treasury yields in recent days, although Fed Governor Lael Brainard on Tuesday acknowledged that concerns over the possibility of a rapid rise in yields could dampen economic activity.
The dollar surged to three-month highs after Powell failed to express concern about a recent sell-off in U.S. Treasuries as some traders had expected, resulting in higher bond yields and demand for the greenback.
The dollar index rose 0.562%, with the euro down 0.77% to $1.1969.
The Japanese yen weakened 0.83% versus the greenback. Dollar/yen rose to 107.89, roughly a seven-month high, while sterling was last trading at $1.3893, down 0.43% on the day.
