What happens over time to the currencies of countries with higher inflation rates than that of the United States?

Explanation

Over the long run, countries that have a relatively higher inflation rate than the US will see a depreciation of their domestic currency against the US dollar. This is because countries with high inflation will have a high money supply, and domestic interest rates will rise and so domestic currency will depreciate. On the other hand, countries that have a relatively lower inflation rate than the US will see an appreciation in their domestic currency against the US dollar. This is because countries with low inflation will have a low money supply, and domestic interest rates will decrease or will be lower than the US rates and so domestic currency will appreciate.

Sample Response
