远期点不理解

问题如下：

The JPY/AUD spot exchange rate is 82.42, the JPY interest rate is 0.15%, and the AUD interest rate is 4.95%. 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：

The forward exchange rate is given by

The forward points are 100 X (F— S) =100 X (81.443 — 82.42) =100 X (-0.977) =—97.7. Note that because the spot exchange rate is quoted with two decimal places, the forward points are scaled by 100.

中文解析：

远期汇率由下图公式所得:

远期点是100 X (F - S) =100 X (81.443 - 82.42) =100 X(-0.977) = - 97.7。请注意，由于即期汇率以小数点后两位表示，远期汇率点按100进行缩放。
