Folks, in the 2009 morning paper, there is a Q (# 9) on the credit risk for a JPY / CAD put option. To summarize my confusion there: while we need to find the potential credit risk for the option expiring in 6 months (long put), should we use the strike rate and the current spot rate, or should we use the strike and forward rate 6 months down the line?
Also, if the diff between the forward (or the spot, based on what we use) and the strike is positive, the long faces no credit risk, right?
Am tending to think we should use the forward rate, but the recommended solution uses the spot.
Appreciate if someone can comment here. Thanks!
