定义
递延利息债券一种债务工具，可以在未来特定日期才支付利息。和大部分债券不同，递延利息债券在到期前不会支付票息，它的利息是在债券到期日一次支付。例如，面值为500元，年收益率为6%的一年期递延利息债券在到期日会支付给投资者530元（本金500元加上利息30元）。

递延利息债券英文原文解释

A debt instrument that pays interest only upon maturity. Unlike most bonds, a deferred interest bond does not make periodic, or "coupon," payments over its lifetime. Instead, the interest accrues and is paid out when the bond expires (matures). For example, a one-year deferred interest bond that has a par value of $500 and an annual yield of 6% would pay the investor $530 when the year was up (the initial $500 investment plus $30 in interest).
