A weekly
Dutch auction held for the
sale of 13-week and 26-week
U.S. Treasury bills, or a monthly auction for 52-week bills. In a Treasury bill auction, the bills are offered at a relatively high
price, which is gradually lowered until a potential
buyer indicates it wishes to buy at that
price. The interest rates on these Treasury bills are used as benchmarks for short-term
interest rates. It should be noted that the Treasury also sets aside securities for those who do not enter a , but have indicated they are willing to pay whatever the winning bid happens to be.
