Especially in a soft currency country. Between higher local inflation rates and appreciating currency, an expat could see effective US$ costs rising at double digit rates. In the past when that has happened, late 70s, late 80s, and even in the 90s, people exchanged large sums of $$ to local currency just in time to find themselves trapped by devaluation and exchange controls.Yes I think that was the question. Income and expenses in different currencies. Not as easy or as simple to hedge as you might think at first.
