彻底错乱了，在视频的哪里有讲

问题如下：

Analyst Bob is studying foreign exchange market. He observes that:

1. The spot exchange market rate is 1.5500 USD/GBP

2. The 6-month Libor for dollars is 0.58, while the 6-month Libor for pounds is 0.62

So, Bob wants to calculate the USD/GBP exchange rate in 6 months but he finds that the forward currency contracts are not available. Which international parity condition should he use?

选项：

A.

Uncovered interest rate parity.

B.

Both covered interest rate parity and Uncovered interest rate parity.

C.

Covered interest rate parity.

解释：

A is correct.

考点：Interest rate parity

解析：解题的关键在与题目中一句话"the forward currency contracts are not available."这就表明因为没有远期合约的参与，所以没有套利机制保证covered interest rate parity成立，所以这时只能选用Uncovered interest rate parity。
