Fixed exchange rates, a cornerstone of international finance, play a pivotal role in shaping global commerce and investment landscapes. This article delves into their intricacies, exploring the historical evolution, practical understanding, and the balance of benefits and challenges they present.

Historical Context of Fixed Exchange Rates

The concept of fixed exchange rate systems has evolved over centuries, but its modern form gained prominence with the Bretton Woods Agreement in 1944. This system was designed to rebuild the global economy after World War II by creating a stable international monetary framework. Under the Bretton Woods system, countries pegged their currencies to the US dollar, which in turn was backed by gold at a fixed rate of $35 per ounce. This arrangement aimed to maintain relative exchange rate stability, promote international trade, and prevent competitive currency devaluations.

To support this fixed exchange rate regime, the International Monetary Fund (IMF) was established, providing financial assistance to countries facing balance of payments problems. While Bretton Woods initially succeeded in fostering economic stability, it began to falter in the 1960s due to rising inflation and balance of payment deficits in the US. In 1971, the US suspended gold convertibility, leading to the system’s collapse and a shift toward floating exchange rates.

Despite its end, the legacy of fixed exchange rates continues, as many countries still choose to peg their currencies to major currencies like the US dollar or the euro, seeking the economic predictability such systems offer.

Understanding Fixed Exchange Rates

A fixed exchange rate is a system where a country's currency value is tied to another major currency or a basket of currencies. Specifically, when a currency peg is established, the government commits to maintaining the currency within a specified narrow range around the targeted rate, often within a band of ±1% to ±2%.

Role of Central Banks and Foreign Reserves

Central banks play a pivotal role in maintaining a pegged currency. To defend the peg, a central bank must actively intervene in the foreign exchange (forex) market. When the currency’s value drifts from the fixed rate, the central bank buys or sells its currency to adjust supply and demand, keeping the value within the target range.

These operations require substantial foreign reserves—typically in the currency to which the domestic currency is anchored. These reserves act as a buffer to absorb shocks and counteract any pressures that could destabilise the peg.

Impact on Monetary Policy and Interest Rates

Maintaining currency pegging has a significant impact on a country's monetary policy. The central bank's primary focus becomes defending the peg, often at the expense of other economic goals, such as controlling inflation or stimulating growth.

Since the central bank must prioritise the peg, it has limited ability to set interest rates independently. Instead, interest rates often need to align closely with those of the anchor currency’s country to prevent capital flight and maintain the anchor’s credibility. This lack of flexibility can lead to challenges, particularly when the economic conditions in the pegging country differ from those in the anchor currency’s economy.

Implications of a Currency Peg

For the pegging country, a currency peg may offer economic stability and predictability, which are vital for fostering a favourable environment for trade and investment. Businesses can plan with greater certainty, knowing conversion rates will remain stable.

However, all this comes with significant challenges. Countries with fixed exchange rates often lose autonomy over their monetary policy, as maintaining the anchor becomes the primary focus. This can limit the country's ability to respond to domestic economic issues. Additionally, a currency peg can impact the trade balance; if the anchored currency is overvalued, it may harm exports, while an undervalued peg could increase inflation.

On a global scale, pegged exchange rates influence international trade and investment flows by reducing exchange rate volatility, making global transactions smoother. However, these systems also carry risks. If a pegged currency becomes misaligned with its true economic value, it can attract speculative attacks, where investors bet against the currency, leading to potential financial crises. Such scenarios can destabilise not only the pegging country but also ripple through global markets and negatively impact the world economy.

List of Fixed Exchange Rate Currencies

As of 2024, several currencies operate under a fixed exchange rate system. Notable fixed exchange rate examples include:

• Hong Kong dollar (HKD) - One of the most well-known currencies anchored to the USD, the HKD is maintained at approximately 7.8 to the US dollar, providing relative stability to Hong Kong’s financial markets since 1983.
• United Arab Emirates dirham (AED) - Pegged to the US dollar since 1997, the AED is maintained at around 3.67 to 1 USD, supporting the UAE's oil-driven economy.
• West African CFA franc (XOF) and Central African CFA franc (XAF) - Both pegged to the euro at a fixed rate of 655.957 CFA francs to 1 euro, these currencies provide economic stability across 14 African countries.
• Bahamian dollar (BSD) - Anchored to the US dollar at a 1:1 ratio, the BSD facilitates trade and tourism in the Bahamas, closely linked to the US economy.
• Danish krone (DKK) - Pegged to the euro within a narrow band, typically around 7.46 DKK to 1 euro, the krone's peg supports Denmark’s economic ties with the Eurozone.
• Saudi riyal (SAR) - Pegged to the US dollar since 1986, the SAR is maintained at approximately 3.75 to 1 USD, stabilising Saudi Arabia's oil-reliant economy.

Fixed Exchange Rate Pros and Cons

While many economies choose a floating system nowadays, there are pros and cons of a fixed exchange rate.

Advantages of a Fixed Exchange Rate

• Stability in Global Trade: Pegged currencies reduce the uncertainty and risk associated with floating currencies, making it easier for businesses to plan and engage in international commerce.
• Reduced Risk in International Investments: Investors are more likely to invest in countries with currencies that have predetermined rates because it lowers the risk of losing money through price fluctuations.
• Control of Inflation Rates: Countries can maintain low inflation levels by pegging their currency to a stable, low-inflation economy.
• Prevent Competitive Devaluations: Such a regime prevents countries from engaging in competitive devaluations, which may lead to a 'race to the bottom' and global economic instability.
• Increased Policy Discipline: Anchored rates can impose discipline on a country's fiscal and monetary policies, as maintaining the peg requires consistent, responsible economic management.
• Simplified Transactions: A fixed currency simplifies the process of global transactions by providing predictability in exchange costs, reducing the need for complex hedging strategies.

Disadvantages of a Fixed Exchange Rate

• Overvaluation or Undervaluation: Maintaining a set rate might lead to misalignment, where a currency may become overvalued or undervalued relative to its economic fundamentals.
• High Costs of Maintenance: To maintain the peg, countries often need to hold large reserves of foreign currency, which may be costly and economically inefficient.
• Lack of Monetary Policy Flexibility: Countries lose the ability to set their own interest rates and conduct independent monetary policy, as they must focus on maintaining the peg.
• Vulnerability to External Shocks: Tied conversion rates can make a country more susceptible to economic problems in the nation to which its currency is pegged.
• Reduced Responsiveness to Domestic Conditions: An anchored currency regime limits a country’s ability to respond to domestic economic changes, such as inflation, unemployment, or economic downturns.
• Risk of Speculative Attacks: If investors believe a currency is overvalued or undervalued, they may engage in speculative attacks, leading to severe financial crises.

Fixed Exchange Rates in Modern Trading

In modern trading, understanding the dynamics of fixed currencies offers traders specific advantages and insights:

• Forex Pairs: Traders can anticipate less volatility in forex involving a fixed value, allowing for more solid long-term trading strategies.
• Indicator of Economic Policies: The status and changes in a fixed rate potentially signal shifts in a country's monetary and fiscal policies, providing traders with crucial information for decision-making.
• Trade and Investment Decisions: Understanding which countries have pegged rates can guide traders in making informed decisions about trade and investment opportunities.
