A fixed exchange rate, also known as a pegged exchange rate, is a system where a country’s currency value is tied to another major currency or a basket of currencies. This method ensures the country’s exchange rate remains constant, maintaining monetary stability and predictability for international trade.
Historical Context
Evolution
- Bretton Woods System (1944-1971): Post-World War II, the Bretton Woods Agreement established fixed exchange rates where currencies were pegged to the US dollar, which was convertible to gold.
- Post-Bretton Woods Era: After the collapse of the Bretton Woods System in 1971, some countries retained fixed or semi-fixed exchange rate systems, while others shifted to floating exchange rates.
Notable Events
- Plaza Accord (1985): An agreement among the G5 nations to depreciate the US dollar relative to the Japanese yen and the German Deutsche Mark.
- European Exchange Rate Mechanism (ERM): Initiated in 1979, aimed to reduce exchange rate variability and achieve monetary stability in Europe before the introduction of the euro.
Types of Fixed Exchange Rates
- Hard Peg: Complete commitment to maintain exchange rates with little to no fluctuation.
- Soft Peg: Allows for slight adjustments within a predetermined range.
Key Events and Models
Important Interventions
- Argentina’s Currency Board (1991-2002): Tied the Argentine peso to the US dollar to control hyperinflation but eventually collapsed due to economic crises.
- Hong Kong Monetary Authority (HKMA): Maintains a fixed exchange rate system with the US dollar, utilizing a strong currency board arrangement.
Mathematical Models
Fixed Exchange Rate Formula:
$$ E = \frac{D}{S} $$
Where:
- \( E \) is the exchange rate.
- \( D \) is the domestic currency.
- \( S \) is the foreign currency or basket value.

Importance and Applicability
Benefits
- Predictability in Trade: Facilitates international trade by reducing currency risk.
- Inflation Control: Stabilizes domestic inflation by anchoring expectations to a stable currency value.
Drawbacks
- Loss of Monetary Autonomy: Limits the central bank’s ability to respond to domestic economic changes.
- Speculative Attacks: Vulnerable to market speculation that can deplete foreign reserves.
Examples
- China (pre-2005): Pegged the Renminbi to the US dollar to boost exports.
- Gulf Cooperation Council (GCC) countries: Peg their currencies to the US dollar to stabilize oil revenues.
Considerations
- Foreign Reserves: Sufficient reserves are critical to maintain the fixed exchange rate.
- Fiscal Discipline: The government must ensure consistent economic policies to support the peg.
Related Terms
- Floating Exchange Rate: Currency value determined by market forces without direct government intervention.
- Crawling Peg: Exchange rate adjusted periodically in small amounts at a fixed rate.
Comparisons
- Fixed vs. Floating: Fixed exchange rates provide stability but limit flexibility, while floating rates offer flexibility but can be volatile.
Interesting Facts
- Gold Standard: An early form of fixed exchange rates where currencies were directly convertible to a specific amount of gold.
- Special Drawing Rights (SDRs): A basket of international reserve assets created by the IMF, sometimes used as a reference for pegging currencies.
Inspirational Stories
- European Stability: Fixed exchange rates played a crucial role in the economic stability of post-war Europe, fostering cooperation and growth leading to the Euro.
