WASHINGTON (AP) -- Interest rates on short-term Treasury bills rose in Monday's auction to the highest levels since earlier this month.
The Treasury Department auctioned $24 billion in three-month bills at a discount rate of 1.200 percent, up from 1.100 percent last week. Another $22 billion in six-month bills was auctioned at a discount rate of 1.550 percent, up from 1.310 percent last week.
The three-month rate was the highest since these bills averaged 1.420 percent on March 10. The six-month rate was the highest since these bills averaged 1.810 percent on March 3.
The discount rates reflect that the bills sell for less than face value. For a $10,000 bill, the three-month price was $9,969.67 while a six-month bill sold for $9,921.64.
Separately, the Federal Reserve said Monday that the average yield for one-year Treasury bills, a popular index for making changes in adjustable rate mortgages, fell to 1.35 percent last week from 1.52 percent the previous week.
