Currency pegging is a monetary policy in which a country’s government or central bank fixes its national currency’s exchange rate to another major currency, such as the U.S. dollar or the euro.
Types of Currency Pegging
- Fixed Peg: The currency’s exchange rate is fixed against another currency or a basket of currencies.
- Crawling Peg: The fixed exchange rate is periodically adjusted based on specific economic indicators.
- Target Zone or Band: The currency is allowed to fluctuate within a specified range around the pegged rate.
Mechanisms of Currency Pegging
- Foreign Exchange Reserves: The central bank maintains sufficient foreign reserves to manage the value of its currency.
- Market Intervention: Regular buying or selling of the currency in foreign exchange markets to maintain the peg.
- Monetary Policy Adjustments: Aligning domestic interest rates with the pegged currency’s interest rates.
Historical Context
Currency pegging has been a part of global trade and economic policy for centuries. One notable example is the Bretton Woods System, which established a system of fixed exchange rates after World War II.
Recent Examples
- China and the U.S. Dollar: China maintained a peg to the U.S. dollar for several years to stabilize trade relationships.
- Hong Kong Dollar: Pegged to the U.S. dollar since 1983, contributing to Hong Kong’s economic stability.
Pros and Cons of Currency Pegging
Advantages
- Stability: Provides a stable exchange rate, reducing the risks of currency volatility in international trade.
- Confidence: Promotes investor and market confidence, leading to increased foreign investment.
- Inflation Control: Helps in controlling domestic inflation if the pegged currency belongs to a low-inflation country.
Disadvantages
- Loss of Sovereignty: Limits the flexibility of domestic monetary policy to react to economic changes.
- Foreign Reserve Requirement: Requires substantial foreign reserves to maintain the peg, which can be economically taxing.
- Risk of Speculative Attacks: Vulnerable to speculative attacks if market participants believe the peg is unsustainable.
Economic Implications
Trade Balance
Pegging can influence a country’s trade balance by making exports cheaper or more expensive depending on the pegging currency.
Capital Flows
Fixed exchange rates can attract capital inflows due to perceived stability, but can also lead to rapid outflows if confidence in the peg wanes.
Comparisons with Other Systems
Floating Exchange Rate
Unlike a pegged system, a floating exchange rate is determined by market forces, providing greater monetary policy flexibility but more currency volatility.
Managed Float
A managed float system allows the currency to fluctuate but with occasional central bank interventions to stabilize significant fluctuations.
Related Terms
- Exchange Rate Manipulation: Influencing the exchange rate by various means for economic advantage.
- Currency Board: A monetary authority that maintains a fixed exchange rate with a foreign currency.
