题目
The yield spread of a specific bond over the standard swap rate in that currency of the same tenor is best described as the:
选项
A.I-spread.
B.Z-spread.
C.G-spread.
答案
A
解析
： A is correct. The I-spread, or interpolated spread, is the yield spread of a specific bond over the standard swap rate in that currency of the same tenor. The yield spread in basis points over an actual or interpolated government bond is known as the G-spread. The Z-spread (zero-volatility spread) is the constant spread such that is added to each spot rate such that the present value of the cash flows matches the price of the bond. ： A是正确的。I-利差，或称差值利差，是指某一特定债券在同一期限货币的标准互换利率上的收益率利差。以基点计算的实际或差值政府债券收益率差价称为G差价。Z价差（零波动性价差）是一个固定价差，加在每个即期利率上，使现金流的现值与债券的价格相匹配。
