Exchange Rate Regimes and Currency Crises
Exchange rate regimes refer to how a country manages its currency in relation to others, such as fixed, floating, or pegged systems. The choice of regime influences economic stability and vulnerability to currency crises, which occur when a sharp depreciation or loss of confidence leads to financial turmoil. Poorly managed regimes or inconsistent policies can trigger crises, causing inflation, capital flight, and economic disruptions, highlighting the importance of sound exchange rate management.

❓ Frequently Asked Questions
What is an exchange rate regime?
An approach a country uses to manage its currency’s value relative to other currencies, defining how freely the rate moves and how the central bank intervenes.
What are fixed, floating, and pegged exchange rate regimes?
Fixed: the currency rate is held at a specific level; the central bank defends the peg with reserves. Floating: the rate is determined by market supply and demand with minimal intervention. Pegged: the currency is tied to another currency within a narrow band and adjusted only within that band.
How does the choice of regime affect vulnerability to currency crises?
Fixed and pegged regimes can be vulnerable if fundamentals deteriorate or confidence falls, since authorities must defend the peg and may exhaust reserves. Floating regimes allow automatic adjustment but can be more volatile; credibility and reserve adequacy matter.
What is a currency crisis?
A sudden, sharp depreciation or loss of confidence in a country’s currency, often with rapid capital outflows, reserve depletion, and financial instability.
