问题如下：

Q. The JPY/AUD spot exchange rate is 82.42, the Japanese yen interest rate is 0.15 percent, and the Australian dollar interest rate is 4.95 percent. If the interest rates are quoted on the basis of a 360-day year, the 90-day forward points in JPY/AUD would be closest to:

选项：

A.–377.0.
B.–97.7. C.98.9.

解释：

B is correct. The forward exchange rate is given by:

F_{\frac{J P Y}{A U D}} = S_{\frac{J P Y}{A U D}} (\frac{1 + r_{J P Y} τ}{1 + r_{A U D} τ}) = 82.42 (\frac{1 + 0.0015 (\frac{90}{360})}{1 + 0.0495 (\frac{90}{360})})

= 82.42 \times 0.98815 = 81.443.

The forward points are as follows:

100 × (F × S) = 100 × (81.443 – 82.42) = 100 × (–0.977) = –97.7.

Because the spot exchange rate is quoted with two decimal places, the forward points are scaled by 100.

Because the spot exchange rate is quoted with two decimal places, the forward points are scaled by 100.为什么？

嗨，从没放弃的小努力你好：

Hello，亲爱的同学~

同学这里先要理解point的含义。

1个point，是指最小变动单位。

因此，-97.7，是指-97.7个最小变动单位。

而最小变动单位，又取决于汇率数字小数点位数。

理解以上知识点后，我们再看这个问题。

本体题目中给的汇率数字是：82.42。

这个数字，是2位小数。表示最小变动0.01。

因此，需要乘以100。

----------------------------------------------
就算太阳没有迎着我们而来，我们正在朝着它而去，加油！
