first of all, you are correct, this will not be physically delivered, it will just cash settle in CHF at a specified rate, which of course as you have pointed out adds CHF risk to this optioni think you're confusing yourself with underlyings. the issue here that you're not addressing properly is that now you have three underlying spots, EURUSD, USDCHF, and EURCHFlet's take for example a EURUSD call option cash settling into CHFclearly you are long EUR and short USD from the vanilla aspect of the option, and long CHF since you want the value of the cash settlement to be greater when you get it.. this translates into deltas of long EURUSD, short USDCHF, short EURCHF.. when viewing your risk you'll of course just look at the net EUR, USD, and CHF deltas so you can hedge them in an efficient manner (the long EURUSD should overpower the short EURCHF to leave you net long EUR)... these deltas will be sensitivity to the other underlyings, i.e. you'll have cross gamma like d(USDCHF delta)/d(EURUSD spot) as well as regular gammahope this helps you out
