Fixed Exchange Rate

What Does Fixed Exchange Rate Mean?
A country's exchange rate regime under which the government or central bank ties the official exchange rate to another country's currency (or the price of gold).  The purpose of a fixed exchange rate system is to maintain a country's currency value within a very narrow band.  Also known as pegged exchange rate.

Fixed rates provide greater certainty for exporters and importers. This also helps the government maintain low inflation, which in the long run should keep interest rates down and stimulate increased trade and investment.
