Coupon rates on newly issued bonds closely follow the level of interest rates in the market. 新发行的债券息票率严格按照市场利率水平而定。
Fixed rate bonds pay a pre-determined coupon and FRNs pay coupons at a premium above the bank's fixed deposit rate.Bonds that do not pay interest are called zero coupon bonds. 这些支付的利息叫做息票，通常半年或一年支付一次。
