I suspect that Mircea Popescu, as in Mircea Popescu's Options Emporium (MPOE) might suggest that the fluctuations in price aka volatility of exchange rate thing is actually a finance thing rather than purely a business thing.

Aren't options supposed to be the financial world's answer to such "problems" ?

Isn't being caught out by a change of price aka exchange-rate really just a symptom of a failure to properly hedge oneself with an appropriate array of options?

Oughtn't payment processors and such be able to offer a stable price across a span of time by proper employment of options?
