Is a put option on the ¥ with a strike price in €/¥ also a call option on the € with a strike price in ¥/€? Explain.
The above statement is correct
Step 1 - Concept
1. First of all we have to understand the concept of base currency
If the rate is Euro / Yen base currency is Yen
If the rate is Yen / Euro base currency is Euro
2. depreciation in base currency also means appreciation in price currency
Step - 2 Put option on Yen with a strike price in Euro / Yen
Above option is a put option on Yen, ie the buyer of put option will make profit when yen depreciates (which also means euro appreciates)
Step - 3 Call option on Euro with a strike price in Yen / Euro
Above option is a call option on Euro, ie the buyer of call option will make profit when euro appreciates (which also means Yen depreciates)
Step 4 - Comparision
If we closely observe we are making profit in both the cases when yen depreciates OR euro appreciates, therefore we can conclude a a put option on the ¥ with a strike price in €/¥ also a call option on the € with a strike price in ¥/€
