Actually have come to understand the fact that when ever dollar increases it may likely cause the depreciation of other currencies in underdeveloped countries. Particularly this might make this underdeveloped countries to be very poor. It can also make them not to engage in the global market of trading, because their currencies can not meet up to this increase in dollar. I think it’s really a global issue that needs to be addressed in order to help this underdeveloped countries.
Only countries that depended on imports and exports and did not have good policies of controlling their exchange rates are affected; the effect happen when your country’s currency lose value to US Dollar, it is not that the Dollar increases in value but the country’s currency loses value which is mainly caused by inflation.
High demand and been dependent on importation is the reason behind some countries currencies to keep depreciating, if all countries will depend solely on their own products, their currency value will be intact and will not be affected yes by any country’s currency value.
