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 for bid and 1.5505 for ask.
2. The 6-month forward rate is 1.5532 USD/GBP for bid and 1.5540 for ask.
So, Bob can get which of the following conclusions?
选项:
A.The 6-month USD interest rate is less than the 6-month GBP interest rate.
B.The 6-month USD interest rate is greater than the 6-month GBP interest rate.
C.The 6-month USD interest rate is equal to the 6-month GBP interest rate.
解释:
B is correct.
考点:Interest rate parity
解析:根据利率平价理论,我们可以得到如下公式:
现在分析师Bob观察到的结果是 > 。因此,等式右边这一项数值一定大于1。所以该项中分子的 分母的 。所以选B。
现在观察到了汇率水平整体都变了,不存在重叠部分,可以得到答案的结论,如果bid和ask的价格区间在S0和F有重叠怎么判断,取平均值吗?还是咋比较?
