Treasury yields have jumped in the past three weeks, in line with a dramatic sell-off in German government debt, and some investors are taking advantage of the higher yields.
Benchmark 10-year Treasury notes were last up 25/32 in price to yield 2.15 percent, down from 2.24 percent late on Thursday.
The dollar index, a measure of the greenback against major currencies, was down 0.2 percent and fell for a fifth straight week, the longest stretch of declines in four years.
The dollar also fell to a three-month low against the euro. In late U.S. trading, the euro rose 0.4 percent to $1.1455 , after earlier hitting a three-month peak of $1.1466.
On Wall Street, the Dow Jones industrial average rose 20.32 points, or 0.11 percent, to end at 18,272.56, the S&P 500 gained 1.63 points, or 0.08 percent, to 2,122.73 and the Nasdaq Composite dropped 2.50 points, or 0.05 percent, to 5,048.29.
The pan-European FTSEurofirst 300 index closed down 0.5 percent, with export-focused German stocks among the hardest hit as the euro gained against the dollar.
In commodities trading, U.S. oil futures ended lower as investors questioned the recent rally, while gold held near three-month highs as the dollar eased.
U.S. crude settled down 19 cents at $59.69 a barrel, after falling more than $1 during the session. Brent settled up 11 cents at $66.81 a barrel.
