Interest rates on short-term Treasury bills rose in Monday's auction with rates on six-month bills climbing to their highest level in more than two years.

The Treasury Department auctioned $24 billion in three-month bills at a discount rate of 0.055 percent, up from 0.035 percent last week. Another $24 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 0.095 percent on Feb. 10. The six-month rate was the highest since six-month bills averaged 0.160 percent on Oct. 29, 2012.

The discount rates reflect that the bills sell for less than face value. For a $10,000 bill, the three-month price was $9,998.63, while a six-month bill sold for $9,992.21. That would equal an annualized rate of 0.056 percent for the three-month bills and 0.157 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 0.23 percent last week from 0.20 percent the previous week.
