Trading Example
On Day 1, customer sells ¥10,000,000 against USD at the going spot rate of 123.20. His position is left open until Day 3.
On Day 3, customer buys ¥10,000,000 against USD to close out his position at the going spot rate of 124.10.
Profit/ Loss and Interest Differential calculations:
Profit on exchange rate:
(¥10,000,000 ÷ 123.20) - (¥10,000,000 ÷ 124.10) = USD588.65
Suppose USD interest is at a premium to YEN by 1%, position interests amount to:
¥10,000,000 ÷ 123.20 x 1% ÷ 360 days x 2 days = USD4.51
Total profit from the transaction:
USD588.65 + USD4.51 = USD593.16
