U.S. government bond prices held higher on Tuesday, after the Treasury Department auctioned $26 billion in two-year notes at a high yield of 0.699 percent on Tuesday, its highest since December.
The bid-to-cover ratio, an indicator of demand, was 3.27, higher than August's 3.16, but below a recent average of 3.41.
Indirect bidders, which include foreign central banks, were awarded 43.2 percent, the smallest since May, while direct bidders, which include domestic money managers, brought 13.3 percent, the highest since May.
The yield on the benchmark 10-year Treasury was down 6.2 basis points at 2.14 percent after hitting a session low of 2.1135 percent, while 30-year yields were down 7.6 basis points at 2.9484 percent, after hitting a session low of 2.9178 percent.
