WASHINGTON (AP) -- Interest rates on short-term Treasury bills rose slightly in Monday's auction, with three-month bills rising from a record-low to their highest level in five weeks.
The Treasury Department auctioned $26 billion in three-month bills at a discount rate of 0.015 percent, up from an all-time low of zero percent last week and the previous week. Another $26 billion in six-month bills was auctioned at a discount rate of 0.110 percent, up from 0.080 percent last week.
The three-month rate was the highest since three-month bills averaged 0.055 percent five weeks ago on Sept. 14. The six-month rate was the highest since those bills averaged 0.115 percent on Sept. 21.
The discount rates reflect that the bills sell for less than face value. For a $10,000 bill, the three-month price was $9,999.62, while a six-month bill sold for $9,994.44. That would equal an annualized rate of 0.015 percent for the three-month bills and 0.112 percent for the six-month bills.
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 0.23 percent last week from 0.27 percent the previous week.
