I am on the other side of the fence compared to the two previous comments. There seems to me that a great need of financial protection needs to be implemented for the exact reason of thwarting a major financial meltdown like the previous ones in history that we have experienced. Currency hedging does just that, it provides a layer of protection for investors that are trading in currency and cash flow.
This means of protection is especially important when dealing with foreign currency hedge issues. Only when our world comes together enough to agree on a single financial system will the perils of foreign currency trading cease to exist because we will have completely converted over to a universal currency in which anyone can be assured of the value, no matter what your geographic or socioeconomic status is.
This is true freedom people. The ability to trade in a universal fashion that is uninhibited by tariffs, taxes and other risks to products, services and currency.
