WASHINGTON (AP) -- Interest rates on both three-month and six-month Treasury bills rose in Monday's auction.
The Treasury Department auctioned $24 billion in three-month bills at a discount rate of 0.015 percent, up from 0.01 percent last week. Another $24 billion in six-month bills was auctioned at a discount rate of 0.08 percent, up from 0.07 percent last week.
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 $9,995.96. That would equal an annualized rate of 0.015 percent for the three-month bills and 0.081 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, rose to 0.27 percent last week from 0.26 percent the previous week.
