问题如下：
The CIO of a Canadian private equity company wants to lock in the interest on a three-month “bridge” loan his firm will take out in six months to complete an LBO deal. He sells the relevant interest rate futures contracts at 98.05. In six-months’ time, he initiates the loan at 2.70% and unwinds the hedge at 97.30. The effective interest rate on the loan is:
选项：
A. 0.75%.
B. 1.95%.
C. 2.70%.
解释：
B is correct.
The CIO sells the relevant interest rate future contracts at 98.05, locking in a forward rate of 1.95% (= 100 – 98.05). After six months, the CIO initiates the bridge loan at a rate of 2.70%, but he unwinds the hedge at the lower futures price of 97.30, thus gaining 75 bps (= 98.05 – 97.30). The effective interest rate on the loan is 1.95% (= 2.70% – 0.75%).
请问题目中说的interest rate futures，为什么默认就成了eurodollar futures？老师上课的时候我记得说过，interest rate futures其实就是交易所市场的FRA，基础资产是利率，和eurodollar futures（基础资产是bond）是不同的，long方的profit/loss是相反的。这该怎么理解呢？考试时应该把它当作FRA来做还是eurodollar futures做呢？
