Currency Regimes– Fixed Parity and Target Zone

Fixed parity and target zone are two types of currency regimes that countries can adopt to manage their exchange rates.

Fixed parity regime involves setting a fixed exchange rate between the domestic currency and a foreign currency, typically the US dollar or the euro. The central bank intervenes in the foreign exchange market to maintain the fixed exchange rate by buying or selling domestic currency as necessary. This regime provides certainty and stability for international trade and investment, but it can also limit a country's ability to respond to economic shocks and can lead to imbalances in trade and capital flows.

Target zone regime involves setting a range of exchange rates within which the central bank allows the exchange rate to fluctuate. The central bank intervenes in the foreign exchange market to keep the exchange rate within the target zone by buying or selling domestic currency. This regime provides more flexibility than fixed parity, allowing the exchange rate to adjust to economic shocks and changes in market conditions. However, it can also be more difficult to maintain than fixed parity, as the central bank must constantly monitor and adjust its interventions to keep the exchange rate within the target zone.

Both fixed parity and target zone regimes require a high level of commitment from the central bank to maintain the exchange rate, and can be vulnerable to speculative attacks and capital flight. Ultimately, the choice of currency regime depends on a country's economic conditions and policy goals.
