Treasury bills (T-bills)

Securities issued by the U.S. government. T-bills normally have fixed terms; that is, the purchaser cannot take possession of the accrued interest for a fixed period of time after purchase. T-bills are auctioned by the Treasury each week; the auction determines the six-month interest rate.
