U.S. government bonds suffered the biggest one-day selloff since November 2013 as a solid U.S. employment report stoked fears that the Federal Reserve may raise interest rates in June.

Investors including hedge funds and portfolio managers shed holdings as they are worried that higher official interest rates from the central bank would undermine the value of outstanding bonds. Traders said the selloff reminded them of the "taper tantrum" during the summer of 2013 when the bond market was rattled by concerns of a pullback in the Fed's bond-buying monetary stimulus.

"The selloff is seriously ugly and quite bloody," said Christopher Sullivan, who oversees $2.45 billion as chief investment officer at the United Nations Federal Credit Union. "The U.S. economy is poised to continue to be on an upward slope. A rate increase in June cannot be ruled out."

Worries over the Fed's policy outlook also pushed down prices in U.S. stocks, gold, copper, silver and crude oil as investors are grappling with the prospect that the central bank's zero interest-rate policy may end sooner than expected. The Fed's monetary stimulus following the 2008 financial crisis has been a big factor pushing up the value of many global markets.

The yield on the benchmark 10-year Treasury note soared to 2.239%, the highest closing level since Dec. 26, compared with 2.110% on Thursday. Yields rise as bond prices fall.

Friday's bond price plunge deepened the selloff in the bond market over the past month, though the yield remains very low compared with a year ago.

The U.S. economy added 295,000 new jobs last month, the Labor Department said on Friday. Economists polled by The Wall Street Journal had expected 240,000. The unemployment rate fell to 5.5% in February from January's 5.7%.

Uncertainty over the timing for the Fed to act has turned trading in the bond market more volatile over the past month.

U.S. job growth has gained traction over the past year but inflation, such as wage growth, remains low, which has supported the Fed's policy of being patient. Meanwhile, a stronger dollar reduces U.S. exporters' competitiveness in global trades and acts to disinflationary pressure, making it harder for the Fed to move inflation back to its 2% target.

Fed Chairwoman Janet Yellen said in late February that the timing of an interest-rate increase depends on how the economy performs.

Ward McCarthy, chief financial economist within the fixed income group at Jefferies LLC, said the magnitude of Friday's selloff suggests "the market got caught leaning the wrong way because of expectations that the bad weather in February would suppress job growth as it did a year ago."

Mr. McCarthy expects the bond market to be "very volatile" this year. The market "will move ahead of the Fed and probably price in a rate increase on a number of occasion before the Fed finally implements the liftoff," he said.

Fed-funds futures, used by investors and traders to place bets on central bank policy, showed Friday that investors see a 22% likelihood of a rate increase in June, compared with 16% a day earlier, according to data from the CME.

The odds of a rate increase at the September Fed meeting were 64% on Friday, compared with 51% on Thursday.

The Fed's next policy meeting is scheduled on March 17-18.

There were some numbers in the jobs report that may lead policy makers to be cautious. Average hourly earnings among private-sector workers rose 3 cents last month to $24.78. Wages were up 2% from a year earlier, a slightly slower annual gain than January's annual gain of 2.2%.

Brian Edmonds, head of interest rates at Cantor Fitzgerald LP in New York, said tame wage pressure means the Fed isn't going to be "very aggressive" in raising interest rates, especially when many other central banks have either cut interest rates or launched bond-buying programs to support growth.

Many investors say bond yields aren't going to rise significantly. Investors have been struggling to find bonds that offer a mix of safety and income in the current low-yield world. A rising dollar adds to the allure of buying U.S. bonds for foreign investors. The dollar soared to the highest level since 2003 against the euro on Friday.

Rick Klingman, managing director of U.S. Treasury trading at Societe Generale SA in New York, said some foreign buyers stepped in after the selloff following the jobs report, including both central banks and money managers.

"The theme remains: there are not lots of places where you can get attractive yields" in high-grade government bond markets, he said.
