Most Treasury prices edged lower Monday after the government saw demand for its debt slip in the first of three auctions this week.
The Treasury Department sold $35 billion in two-year notes at a yield of 0.79 percent.
Investors placed bids for 3.16 times the amount offered. That's a weaker show of demand than the 3.48 average for the last four auctions. The previous four auctions also resulted in lower yields: an average of 0.66 percent.
The two-year yield ended the day at 0.76 percent, up from 0.74 percent late Friday. Bond yields rise when their prices fall. Prices for the five-year and seven-year notes also fell.
The 10-year Treasury note ended unchanged from late Friday. The yield was 3.44 percent.
The 30-year bond rose 9.37 cents for every $100 invested. The slight rise in price left the yield unchanged at 4.50 percent from late Friday.
The Treasury expects to raise a total of $99 billion this week through three auctions. The next one comes Tuesday with the sale of $35 billion in five-year notes.
In the market for short-term Treasury bills, the three-month T-bill paid a 0.09 percent yield. Its discount was also 0.09 percent.
