Bond yields gave up earlier gains on Wednesday after the Treasury Department sold five-year notes at the highest yield for such an offering this year.
The Treasury Department auctioned $35 billion in five-year notes at a high yield of 1.560 percent, the highest since December.
The bid-to-cover ratio, an indicator of demand, was 2.46, compared to last month's 2.56 and a recent average of 2.58.
Yields were little changed from earlier after the announcement.
U.S. five-year notes were last trading at a yield of 1.53 percent, from a yield of 1.52 percent late Tuesday.
Benchmark 10-year U.S. Treasury yields were last at 2.13 percent, from a yield of 2.14 percent late Tuesday. U.S. 30-year Treasury yields fell to a session low of 2.87 percent, after touching 2.93 percent earlier.
