A pegged exchange rate is a type of exchange rate system where a country’s currency is tied to a major foreign currency, often the US Dollar (USD) or Euro (EUR). This system aims to maintain a stable relationship between the domestic currency and the pegged currency, minimizing fluctuations and promoting economic stability.
Historical Context
Historically, many countries have adopted pegged exchange rates to stabilize their economies:
- Bretton Woods System (1944-1971): Post-World War II, most global currencies were pegged to the US Dollar, which was in turn pegged to gold.
- Modern Examples: The Omani Rial is pegged to the USD, enhancing trade and investment stability in Oman.
Types/Categories of Pegged Exchange Rates
- Fixed Peg: The domestic currency is strictly tied to a foreign currency.
- Crawling Peg: Adjusts gradually over time based on economic indicators.
- Horizontal Band Peg: Allows some fluctuation within a specified range.
Key Events
- Bretton Woods Conference (1944): Established the fixed exchange rate system.
- Abandonment of Bretton Woods (1971): Transition to more flexible exchange rates.
Detailed Explanations
Mechanism
- Central Bank Actions: The central bank maintains the peg by buying and selling its currency in the foreign exchange market.
- Interest Rate Adjustments: Altering interest rates to influence capital flows and stabilize the currency.
Importance and Applicability
- Stability: Reduces exchange rate volatility, fostering a predictable environment for international trade and investment.
- Confidence: Enhances investor confidence and attracts foreign investment.
Mathematical Models
Interest Rate Parity
The relationship between interest rates and exchange rates can be represented by:
where:
- \( F \) is the forward exchange rate.
- \( S \) is the spot exchange rate.
- \( i_d \) is the domestic interest rate.
- \( i_f \) is the foreign interest rate.
Purchasing Power Parity
The theory that in the long run, exchange rates should adjust to equalize the price of identical goods in different countries:
where:
- \( \text{ER} \) is the exchange rate.
- \( P_d \) is the domestic price level.
- \( P_f \) is the foreign price level.

Examples
- Omani Rial (OMR): Pegged to the USD at a rate of approximately 0.3849 USD/OMR.
- Hong Kong Dollar (HKD): Pegged to the USD within a narrow band.
Considerations
- Inflation: Pegged rates can influence domestic inflation.
- Foreign Reserves: Requires substantial foreign exchange reserves to maintain the peg.
- Speculative Attacks: Vulnerable to market speculation.
Related Terms
- Floating Exchange Rate: A system where the currency’s value is determined by market forces.
- Currency Board: A fixed exchange rate regime that strictly controls monetary policy.
Comparisons
- Pegged vs. Floating: Pegged rates offer stability but less flexibility; floating rates offer flexibility but can be volatile.
- Fixed vs. Crawling Peg: Fixed pegs are strict, while crawling pegs allow gradual adjustments.
Interesting Facts
- Hong Kong’s Stability: Despite global volatility, Hong Kong has maintained its peg to the USD since 1983.
- China’s Managed Float: China officially calls its system a “managed float,” which closely resembles a crawling peg.
Inspirational Stories
- Oman’s Economic Growth: The stable pegged exchange rate has played a crucial role in Oman’s economic growth and development, attracting foreign investment and trade.

Summary
A pegged exchange rate system, by stabilizing a domestic currency against a major foreign currency, provides crucial benefits for international trade and investment by reducing volatility. This system requires diligent central bank intervention and substantial foreign reserves but plays a pivotal role in fostering economic stability and growth. Historical examples and modern applications illustrate the strategic importance of pegged exchange rates in global economics.
