U.S. Treasurys prices fell slightly for the second straight day after better-than-expected data from the U.S. calmed concerns for the world's largest economy and investors returned to stock markets.
In late afternoon trading, 10-year notes fell 11/32 in price to yield 2.2 percent, up from Thursday's close of 2.155 percent.
On Friday, U.S. Federal Reserve chair Janet Yellen said in a speech that income inequality in the U.S. is near its highest levels of the past 100 years. National housing starts and permits also rose in September, signaling strength in overall economic growth.
The U.S. government reported on Thursday that its count of Americans filing claims for jobless benefits dropped to a 14-year low last week, falling by 23,000 to 264,000. Separately, U.S. industrial production rose 1.0 percent in September, versus expectations of 0.4 percent.
In the afternoon, the 30-year bond price fell 23/32 points to yield 2.974 percent.
Prices and yields are inversely related.
Earlier in the week, investors had flocked to so-called "safe haven" bonds as stock markets plunged across the board and as weaker-than-expected data out of the U.S. increased expectations that the Fed could reassess when it raises interest rates. Wednesday, the 10-year yield tumbled to 1.85 percent.
The latest data could reaffirm expectations that the central bank will not delay a hike in interest rates expected mid-2015.
