At its core, a pegged exchange rate is a deliberate policy choice by a nation or monetary authority to fix the value of its domestic currency to a more stable foreign currency, a basket of currencies, or sometimes a commodity like gold.

Variations on a Fixed Theme Not all pegs are rigid; the spectrum of exchange rate regimes includes hard pegs and soft pegs. Furthermore, a credible peg can help anchor inflation expectations; importers are unable to raise prices simply due to a devaluation, which forces domestic firms to remain competitive through productivity gains rather than price hikes.
Operational Mechanics and Policy Tools For a peg to be effective, the issuing central bank must actively manage the currency supply through open market operations and substantial foreign exchange reserves. By anchoring its value, the pegging nation effectively imports the stability of the anchor currency, which is often the US Dollar, the Euro, or a regional basket, to provide predictability for trade and investment.

A hard peg, such as a currency board arrangement, offers absolute commitment where the domestic currency is fully backed by foreign reserves on a one-to-one basis, effectively eliminating the possibility of devaluation. This mechanism creates a static relationship where the pegging currency maintains a constant exchange rate, minimizing the volatility that characterizes floating exchange rate regimes.
