U.S. Treasurys extended earlier losses on Monday after the U.S. government's auction of 3-year Treasury notes, the first of three debt auctions this week.
The Treasury Department auctioned $26 billion in three-year notes at a high yield of 0.998 percent. The bid-to-cover ratio, an indicator of demand, was 3.18. Indirect bidders, which include major central banks, were awarded 37.7 percent. Direct bidders, which includes domestic money managers, brought 15.2 percent.
Yields on benchmark 10-year notes—used to calculate mortgage rates and consumer loans—closed at 2.36 percent on Monday.
Traders sold some safe-haven Treasurys after prices extended last Friday's rally in early U.S. trading. Analysts said traders sold with the aim of buying them back at lower prices at the Treasury's auctions this week.
