Treasurys slipped on Monday as traders weighed the impact of new debt against a forecast of slower U.S. economic growth.
Treasury prices ended slightly lower as traders braced for $66 billion in new government bond sales this week. The Treasury Department's first debt auction is scheduled for Tuesday with the sale of $32 billion in 3-year notes.
The market got a lift when the International Monetary Fund cut its forecast for U.S. economic growth. In a report released Monday, the IMF lowered its outlook for U.S. economic growth to 2.8 percent in 2011, largely a result of higher oil prices. In January, the IMF had forecast 3 percent growth for the U.S.
Sluggish economic growth raises the appeal of low-paying but relatively safe investments like Treasurys.
The 10-year note fell 3.12 cents. That raised the yield to 3.59 percent from 3.58 percent from late Friday. Bond yields rise when prices fall.
The price of the 30-year bond lost 15.6 cents. Its yield was 4.65 percent, up from 4.64 percent. The yield on the 2-year note rose to 0.84 percent from 0.80 percent.
In the market for short-term Treasury bills, the three-month T-bill paid a 0.04 percent yield. Its discount was 0.05 percent.
