We read about marketable securities. For example, T-bills are the most liquid securities in the money market because of the volumes in which they are issued, their credit quality, and their short maturities. They are issued each week on a discounted basis in maturities of less than one year, typically 13 or 26 weeks. T-bills are available in a minimum denomination of $1,000 with additional amounts in multiples of $1,000, but they are generally traded in round lots of $1,000,000. The discount rate on T-bills is quoted in annualized terms. What instances do you think T-bills would be most beneficial to use?
