<prompt> Human: Sorry if there is a more appropriate sub for this question:I am American, My wife is Brazilian, and see live in the US. She still has money in savings accounts in Brazil, which return 6-8 percent per year 6 is guaranteed. Also, there is no income tax in Brazil on savings accounts.Due to high inflation, this is not a great deal for those living in Brazil. But since we live in the US, and have significant money in low interest savings accounts, is there any reason that we SHOULD NOT send money to Brazil to guarantee 6 interest?Thanks!  <response>: Youre still susceptible to Brazilian inflation because youll have to exchange your USD to BRL. If investors in the United States could take advantage of the high interest rates in Brazil without taking the inflation risk, everyone would be doing it already.
