U.S. Treasury bonds were little changed on Wednesday as weather-clouded data sidelined investors and tensions in Ukraine calmed.
Yields held steady after a rally on Monday and a sell-off on Tuesday as the European Union offered $15 billion and the United States offered $1 billion in financial support to Ukraine, which has been embroiled in a conflict with Russia.
"The market is trying to recover from the sell-off of yesterday. There has been a lot of volatility without much change," said James Sarni, a managing principal at Payden & Rygel in Los Angeles.
In its Beige Book report the Federal Reserve confirmed that severe winter weather had marred a slew of U.S. economic data in the past two months.
Investors also attributed lower-than-expected private employment and service sector growth reports on Thursday to bad weather and will wait for fresh data for a better sense of the pace of the U.S. economy.
