WASHINGTON (AP) — Interest rates on short-term Treasury bills rose in Monday's auction to their highest levels in six weeks.
The Treasury Department auctioned $26 billion in three-month bills at a discount rate of 0.020 percent, up from 0.015 percent last week. Another $26 billion in six-month bills was auctioned at a discount rate of 0.155 percent, up from 0.110 percent last week.
The three-month rate was the highest since three-month bills averaged 0.055 percent on Sept. 14. The six-month rate was the highest since those bills averaged 0.260 percent, also on Sept. 14.
The discount rates reflect that the bills sell for less than face value. For a $10,000 bill, the three-month price was $9,999.49, while a six-month bill sold for $9,992.16. That would equal an annualized rate of 0.020 percent for the three-month bills and 0.158 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, was unchanged at 0.23 percent last week, the same as the previous week.
