Introduction
In the ever-evolving global financial landscape, exchange rates play a crucial role in determining the value of currencies and shaping international trade.
One common approach adopted by countries to manage their currency’s value is through a currency peg, or fixed exchange rate.
In this article, we delve into the concept of currency peg, how it works, its pros and cons, and the broader implications of fixed exchange rates.
Understanding Currency Peg
A currency peg, or fixed exchange rate, refers to a monetary policy where a country’s central bank or monetary authority ties its currency’s value to the value of another currency or a basket of currencies.
This linkage is intended to stabilize the exchange rate and maintain a consistent value for the domestic currency in relation to the anchor currency.
The purpose of a currency peg is to reduce exchange rate volatility, promote price stability, and foster confidence in international trade.
How Currency Peg Works
To implement a currency peg, the central bank of the country must intervene in the foreign exchange market by buying or selling its own currency to maintain the fixed exchange rate.
When the value of the domestic currency strengthens beyond the pegged rate, the central bank sells its currency and buys the anchor currency to prevent further appreciation.
Conversely, when the domestic currency weakens below the pegged rate, the central bank buys its currency and sells the anchor currency to prevent further depreciation.
This continuous intervention helps keep the exchange rate within the desired range.
Pros of Currency Peg
Exchange Rate Stability: Currency pegs provide certainty and stability for traders, businesses, and investors engaged in international transactions, as they know the fixed value of the domestic currency relative to the anchor currency.
Low Inflation: Pegged exchange rates can help control inflation, as the central bank must maintain fiscal discipline to support the peg. This discipline limits the potential for excessive money supply growth.
Boost to Trade: A stable exchange rate can encourage international trade by reducing exchange rate risk, promoting long-term investment, and enhancing price transparency.
Cons of Currency Peg
Loss of Monetary Policy Autonomy: A currency peg limits the central bank’s ability to independently adjust interest rates and implement other monetary policy tools to address domestic economic conditions.
Vulnerability to External Shocks: Pegged currencies may face challenges during global economic shocks or sudden changes in the anchor currency’s value, potentially leading to speculative attacks and currency crises.
Overvaluation or Undervaluation: In the long run, a currency peg may lead to an overvaluation or undervaluation of the domestic currency, affecting the competitiveness of the country’s exports and imports.

Fixed Exchange Rates in the Global Context
Currency pegs have been historically used by countries to manage their exchange rates, but they have faced various degrees of success and challenges.
Some countries maintain a rigid peg, while others adopt a managed float, allowing for limited flexibility around the pegged rate.
The decision to adopt a currency peg depends on a country’s economic and trade objectives, its openness to capital flows, and the stability of the anchor currency.
Conclusion
Currency pegs, or fixed exchange rates, have both advantages and drawbacks. While they can offer stability and predictability in the short term, they also come with risks of external vulnerabilities and reduced monetary policy flexibility.
As countries navigate the complex economic landscape, the choice of a currency regime should be carefully evaluated based on their unique economic circumstances and policy goals.
