Fixed vs Pegged Exchange Rates
Countries seeking currency certainty often adopt fixed or pegged exchange‑rate systems, both aimed at reducing volatility in international trade and prices. Though similar in intent, each method has distinct features and implications.
What Is a Fixed Exchange Rate?
A fixed exchange rate is a system under which a government or central bank pegs its currency to another major currency, a basket of currencies, or a commodity such as gold, within a narrow band. The central bank commits to exchanging domestic currency for the reference asset at a constant rate.
What Does “Pegged” Mean in Practice?
The term “pegged exchange rate” generally refers to a fixed system that may allow slight, controlled fluctuation. For instance, a currency can be pegged to a single currency (e.g. US dollar) or a basket of currencies, and may work within a permitted margin such as ±2%.
How Central Banks Enforce the Peg
To maintain the peg, central banks actively intervene in foreign‑exchange markets:
· If the domestic currency weakens below the peg, the bank sells foreign reserves to buy domestic currency;
· If it strengthens too much, the bank buys foreign currency.
This requires substantial foreign‑currency reserves and continual readiness to intervene.
Benefits of Fixed/Pegged Exchange Rates
1. Stability and predictability for importers, exporters and investors, reducing exchange‑rate risk.
2. Inflation control, as tying the currency to a stable reference can help import price stability.
3. Attraction of foreign investment, since reduced volatility improves investor confidence.
4. Discipline on economic policy, as maintaining a peg often demands prudent fiscal and monetary measures.
Limitations of a Pegged System
1. Large reserve needs: defending the peg requires extensive foreign‑currency holdings.
2. Monetary policy constraints: central banks lose flexibility to adjust interest rates or implement independent policies.
3. Risk of speculative pressure: if markets doubt the peg’s sustainability, attacks can force devaluation.
4. Imbalance potential: artificial rates can distort trade and lead to hidden parallel markets.
Types of Pegged Systems
· Hard Peg (Currency Board): Enforces strict 1:1 backing with foreign reserves, e.g. Hong Kong dollar tied to US dollar at HK$7.80.
· Soft Peg: Includes crawling pegs, bands and adjustable pegs where slight fluctuations are permitted.
· Crawling Peg: The peg is adjusted gradually, often to reflect inflation differentials.
Why Nations Adopt Pegs
· Small or emerging economies often lack deep financial markets and need exchange‑rate stability to build investor confidence.
· Dependence on trade with one currency bloc, such as Caribbean and Middle Eastern nations pegging to USD for consistency.
· Inflation targeting, where a stable peg helps anchor domestic price expectations.
How India Transitioned Away from Pegged Regimes
In 1992–1993, India implemented the Liberalised Exchange Rate Management System (LERMS), enabling partial convertibility and eventually full market determination of the rupee. As trade and capital flowed more freely, the RBI gradually stopped pegging.
Is India Using a Peg Today?
No. Since 1993, India has adopted a managed floating regime, the RBI occasionally intervenes to moderate volatility but does not peg or fix the rupee to any currency.
Conclusion
Both fixed and pegged exchange‑rate regimes seek to stabilise currency value for trade, inflation control, and investor confidence. The choice, ranging from hard peg, soft peg to crawling peg, depends on a country’s policy goals, reserve strength, trade profile and economic maturity. Each option involves trade‑offs in flexibility, cost, and vulnerability.
FAQs on Fixed vs Pegged Exchange Rates
- What is meant by a fixed exchange rate system?
A fixed exchange rate system refers to a currency regime where the value of a country’s currency is maintained at a constant rate against another currency or a commodity.
- What does a pegged exchange rate imply?
A pegged exchange rate implies that a currency is fixed to another currency but may be allowed to fluctuate slightly within a controlled range or be adjusted over time.
- Why do countries choose to peg their currency to another?
Countries peg their currency to achieve greater price stability, encourage foreign trade, and build investor confidence by reducing exchange-rate volatility.
- What are the main disadvantages of maintaining a pegged exchange rate?
The main disadvantages include the need for large foreign exchange reserves, limited flexibility in monetary policy, and vulnerability to speculative attacks.
- What is a crawling peg exchange rate system?
A crawling peg is an exchange-rate system where the currency’s fixed rate is adjusted gradually over time, usually in response to inflation or market pressures.
- Can pegged exchange rates lead to economic crises?
Yes, if a pegged exchange rate becomes unsustainable, it can trigger currency devaluation, reserve depletion, or financial crises, as seen in several past global examples.
- Which countries or types of economies usually use pegged exchange rate systems?
Pegged exchange rate systems are typically used by small, emerging, or trade-reliant economies that aim to maintain currency stability and manage inflation.
