Key differences between Fixed Exchange Rates and Flexible Exchange Rates

Fixed Exchange Rates

Fixed exchange rates refer to a system where the value of one currency is pegged or fixed relative to another currency or a basket of currencies. This fixed relationship is maintained by a central bank or monetary authority through active intervention in the foreign exchange market. The objective of fixing exchange rates is to provide stability and predictability for international trade and investment transactions.

Features of fixed Exchange Rates:

  • Stability:

Fixed exchange rates offer stability in currency valuations, reducing uncertainty for businesses engaged in international trade. This stability encourages cross-border transactions and facilitates long-term planning and investment.

  • Intervention:

To maintain fixed exchange rates, central banks intervene in the foreign exchange market by buying or selling currencies. They adjust their foreign exchange reserves to ensure that the exchange rate remains within the specified band or at a predetermined rate relative to the anchor currency.

  • Anchor Currency:

In a fixed exchange rate system, currencies are often pegged to a stable and widely accepted currency such as the US dollar, euro, or a basket of major currencies. The choice of anchor currency influences the credibility and stability of the fixed exchange rate regime.

  • Constraints on Monetary Policy:

Fixed exchange rates limit the flexibility of monetary policy. Changes in interest rates, money supply, or other monetary tools may be constrained by the need to maintain the fixed exchange rate target. This can impact domestic economic conditions such as inflation and employment.

  • Speculation and Arbitrage:

Fixed exchange rates discourage currency speculation and arbitrage opportunities because deviations from the fixed rate are usually limited or corrected through central bank interventions.

  • Benefits and Challenges:

The main benefit of fixed exchange rates is stability, which promotes international trade and investment. However, maintaining fixed rates requires sufficient foreign exchange reserves, and sudden shifts in economic fundamentals or market sentiment can strain the sustainability of fixed exchange rate regimes.

  • Examples:

Historical examples of fixed exchange rate systems include the Bretton Woods system (1944-1971), where major currencies were fixed to the US dollar, and the European Exchange Rate Mechanism (ERM) before the introduction of the euro.

Flexible Exchange Rates

Flexible exchange rates, also known as floating exchange rates, refer to a system where currency values are determined by market forces of supply and demand in the foreign exchange market. Under this system, exchange rates fluctuate freely and can change continuously throughout the day based on various factors such as economic indicators, geopolitical events, investor sentiment, and trade flows.

Key Features of Flexible Exchange Rates:

  • Market Determination:

The value of a currency under flexible exchange rates is primarily influenced by market participants, including banks, corporations, governments, speculators, and individuals. Changes in economic fundamentals, interest rates, inflation rates, and trade balances influence currency demand and supply, thereby affecting exchange rates.

  • Price Stability:

Flexible exchange rates allow currencies to adjust to changing economic conditions. If a country experiences higher inflation or trade deficits, its currency may depreciate relative to others, which can help correct imbalances over time. Conversely, countries with strong economic performance may see their currency appreciate.

  • Monetary Policy Independence:

Countries with flexible exchange rates have greater flexibility in conducting monetary policy. Central banks can adjust interest rates and money supply to stabilize domestic economic conditions, such as managing inflation or supporting economic growth, without being constrained by fixed exchange rate targets.

  • Trade Competitiveness:

Flexible exchange rates can enhance a country’s international competitiveness. A depreciated currency makes exports cheaper and imports more expensive, potentially boosting export-driven industries and reducing trade deficits.

  • Market Efficiency:

The foreign exchange market under flexible rates is generally more efficient in reflecting economic fundamentals and market expectations. Exchange rate movements provide signals to businesses and investors, guiding decisions on international trade, investment, and capital flows.

  • Exchange Rate Volatility:

While flexible exchange rates offer flexibility, they can also lead to exchange rate volatility. Rapid and unpredictable currency fluctuations may create uncertainty for businesses engaged in international trade and investment, requiring risk management strategies.

  • Examples:

Most major economies today, including the United States, Japan, and those in the European Union, operate under flexible exchange rate regimes. These countries allow their currencies (e.g., US dollar, Japanese yen, euro) to fluctuate freely based on market conditions.

Key differences between Fixed Exchange Rates and Flexible Exchange Rates

Determination Government/central bank intervention Market forces (supply and demand)
Stability High Variable, potentially lower
Flexibility Low High
Adjustment Mechanism Limited adjustments Continuous adjustments
Monetary Policy Limited independence Full independence
Speculation Discouraged Encouraged
Trade Balance May help balance Adjusts naturally
Price Stability Promotes Market-driven
Market Efficiency Potentially lower Generally higher
Risk Management Easier More complex
Currency Pegging Fixed to another currency Not fixed
Example Bretton Woods System Current major economies’ systems

Similarities between Fixed Exchange Rates and Flexible Exchange Rates

  • Exchange Rate Determination:

Both fixed and flexible exchange rate systems involve mechanisms for determining the value of currencies relative to each other. In fixed exchange rates, governments or central banks intervene to maintain a specific value or range for their currency against another currency or basket of currencies. In flexible exchange rates, market forces of supply and demand determine currency values.

  • Global Trade Facilitation:

Both systems facilitate international trade by providing a mechanism for businesses and individuals to exchange currencies. They enable transactions across borders, support import-export activities, and facilitate investment flows between countries.

  • Impact of Economic Factors:

Economic fundamentals such as inflation rates, interest rates, trade balances, and economic growth impact both fixed and flexible exchange rates. Changes in these factors can influence currency valuations under both systems, albeit through different mechanisms.

  • Role of Central Banks:

While central banks play a more direct role in maintaining fixed exchange rates through interventions and foreign exchange reserves management, they still play a significant role in flexible exchange rate systems. Central banks in flexible exchange rate regimes monitor market conditions, influence interest rates, and may intervene occasionally to stabilize extreme fluctuations.

  • Risk Management:

Both fixed and flexible exchange rate systems require businesses and governments to manage currency risk. Businesses engaged in international trade must hedge against exchange rate fluctuations, whether in a fixed or flexible exchange rate environment, to mitigate potential losses and stabilize cash flows.

  • Adaptation to Economic Shocks:

Both systems need to adapt to economic shocks and external influences. Fixed exchange rates may require adjustments or devaluations during economic crises to restore balance, while flexible exchange rates may experience heightened volatility during such periods but allow for more immediate adjustments.
