问题如下：
Which of the following statements is most accurate? An interbank offered rate:
选项：
A. is a single reference rate.
B. applies to borrowing periods of up to 10 years.
C. is used as a reference rate for interest rate swaps.
解释：
C is correct.
Interbank offered rates are used as reference rates not only for floating-rate bonds, but also for other debt instruments including mortgages, derivatives such as interest rate and currency swaps, and many other financial contracts and products. A and B are incorrect because an interbank offered rate such as Libor or Euribor is a set of reference rates (not a single reference rate) for different borrowing periods of up to one year (not 10 years).
考点：interbank offered rate
解析：Interbank Offered Rate，比如LIBOR（London Interbank Offered-Rate）。LIBOR是伦敦几家大行之间相互借贷虚拟利率的平均报价。LIBOR会报5种主要货币，7个主要期限的借贷利率，所以是多种货币、且每种货币内部又有不同期限的一组利率，即a set of reference rate，故选项A不正确。
其Maturity是从1天到1年，最长是12个月，故选项B不正确。
银行同业拆借利率不仅可以用作浮动利率债券的参考利率，也可以用作利率互换的参考利率，故选项C正确。
Libor只能用于短期债的利率参考？这是讲义哪里的知识点？谢谢
