Pegged Exchange Rate
A pegged exchange rate, also known as a fixed exchange rate, is a currency regime in which the country’s currency is tied to another currency, usually USD or EUR. The purpose of a pegged exchange rate is to stabilise the value of the local currency, keeping it at a fixed rate in order to avoid exchange rate fluctuations. A country may decide to stabilise its exchange rate through a pegged exchange rate to prevent an excess of under- or over-valuation. Such arrangements can work well for some time, especially if the country that applies it is seen as credible by foreign exchange markets participants. Sooner or later, however, differences between the currencies concerned —due to inflation rates, productivity levels or other factors— are bound to create uncertainty about the peg, which (paradoxically) could lead to even more exchange rate instability over the medium- to long term.
