A banker's acceptance, or BA, is a promised future payment, or time draft, which is accepted and guaranteed by a bank and drawn on a deposit at the bank. The banker's acceptance specifies the amount of money, the date, and the person to which the payment is due. After acceptance, the draft becomes an unconditional liability of the bank. But the holder of the draft can sell (exchange) it for cash at a discount to a buyer who is willing to wait until the maturity date for the funds in the deposit.
