Answer:
Option (b) is correct.
Explanation:
Given that:
Spot price for the Japanese yen is ¥129.87/$ i.e 1 yen = 1/129.87 = $0.007700
6- month forward rate is ¥128.53 $i.e
1 yen = $0.00780
Yen will move to ¥128.00/$ in the next six months i.e.
1 yen = 1/128
= $0.007813
Here there is opportunity of profit when he purchase yen at forward rate of:
$0.007800 i.e at ¥128.53/$ and sells at 0.007813 i.e at ¥128.00/$ making a profit of $0.000013 per yen.
Therefore, the correct answer is option B i.e buying yen for ¥128.53/$; selling yen at ¥128.00/$.
