WASHINGTON – Interest rates on short-term Treasury bills rose in Monday’s auction with rates on six-month bills rising to the highest level in three weeks.
The Treasury Department auctioned $29 billion in three-month bills at a discount rate of 0.045 per cent, up from 0.040 per cent last week. Another $24 billion in six-month bills was auctioned at a discount rate of 0.080 per cent, up from 0.075 per cent last week.
The three-month rate was the highest since these bills averaged 0.050 per cent on April 29. The six-month rate was the highest since these bills averaged 0.085 per cent on April 22.
The discount rates reflect that the bills sell for less than face value. For a $10,000 bill, the three-month price was $9,998.86 while a six-month bill sold for $9,995.96. That would equal an annualized rate of 0.046 per cent for the three-month bills and 0.081 per cent 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 0.11 per cent last week, the same as the previous week.
