Treasury Department auctions $24 billion of 3-year notes at a high yield of 1.125%

Bond yields held gains on Tuesday after the U.S. government's auction of three-year Treasury notes, the first batch of this week's $58 billion offering of new debt supply.

The Treasury Department auctioned $24 billion in three-year notes at a high yield of 1.125 percent, the highest since April 2011. The bid-to-cover ratio, an indicator of demand, was 3.33, little changed from 3.34 in May.

Indirect bidders, which include major central banks, were awarded 50.7 percent, while direct bidders, which includes domestic money managers, brought 9.7 percent.

"The 3 yr note auction, very sensitive to expectations of Fed rate hikes, was uneventful," said Peter Boockvar, chief market analyst at the Lindsey Group. "Bottom line, the highest yield in 3 months led to only ordinary demand as the complexion and trend of the U.S. Treasury market has clearly changed over the past 2 months."

Three-year note yields were trading at 1.09 percent, up from 1.059 percent on Monday, while yields traded up 2 basis points at 0.70 percent.
