Pegged Exchange Rate

Understanding Pegged Exchange Rate

A pegged exchange rate is a system where a country’s currency value is fixed or tied to another currency, a basket of currencies, or a commodity like gold. Governments and central banks maintain this fixed rate by buying or selling their currency in the foreign exchange market to stabilise its value.

How Pegged Exchange Rates Work

In a pegged system, the central bank sets an official exchange rate and actively intervenes to maintain it. This system differs from floating exchange rates, where market forces determine currency values. Pegged rates help stabilise trade, control inflation, and provide economic certainty.

Types of Pegged Exchange Rates

  1. Fixed Peg – A strict one-to-one peg where the currency moves only within a narrow band (e.g., Hong Kong Dollar to USD).
  2. Crawling Peg – Adjusts periodically based on economic conditions, allowing gradual devaluation or revaluation (e.g., China’s managed float system).
  3. Soft Peg – Allows limited fluctuations around the pegged value but requires central bank intervention when the currency strays too far.

While pegged exchange rates provide stability, they come with risks:

  • Pressure on Foreign Reserves – Central banks must hold large reserves of foreign currency to maintain the peg.
  • Trade Imbalances – An overvalued currency may reduce exports, while an undervalued peg can trigger inflation.
  • Speculative Attacks – Investors may bet against a weak peg, forcing devaluation (e.g., 1997 Asian Financial Crisis).
  • Loss of Monetary Policy Control – A pegged system limits a central bank’s ability to adjust interest rates independently.

Step-by-Step Solutions for Managing a Pegged Exchange Rate

1. Maintaining Foreign Currency Reserves

A country must hold significant reserves of the currency it is pegged to for effective intervention in the forex market.

2. Adjusting Interest Rates

Central banks use interest rate adjustments to influence capital flows and support the peg.

3. Capital Controls

Some countries impose capital controls to limit large movements of money that could destabilise the peg.

4. Monitoring Trade Balances

Policymakers must track imports and exports to ensure that the peg does not create imbalances that could weaken the economy.

5. Transitioning to a Flexible Exchange Rate

If maintaining a peg becomes unsustainable, a country may gradually shift to a managed float or fully floating exchange rate.

Practical and Actionable Advice

To understand and navigate pegged exchange rates:

  • Monitor Economic Indicators – Inflation, interest rates, and trade balances impact the sustainability of a peg.
  • Assess Foreign Reserves – A country with low reserves may struggle to defend its currency peg.
  • Stay Aware of Government Policies – Central bank interventions can affect forex markets and investment decisions.
  • Diversify Investments – If investing in a country with a pegged currency, consider hedging against potential devaluations.

FAQs

Why do countries use pegged exchange rates?

They provide stability, control inflation, and facilitate predictable trade relationships.

Which countries have pegged exchange rates?

Hong Kong (HKD to USD), Saudi Arabia (SAR to USD), and UAE (AED to USD) are examples of pegged currencies.

What happens when a currency peg fails?

A failed peg leads to devaluation, financial instability, and potential economic crises.

How does a pegged exchange rate affect inflation?

A strong peg can reduce inflation by stabilising import prices, while an undervalued peg may increase inflation.

Can a country change its currency peg?

Yes, central banks can adjust the peg or transition to a managed or floating rate.

What is the difference between a fixed and pegged exchange rate?

A pegged rate allows some fluctuation, while a fixed rate remains unchanged unless officially adjusted.

How do central banks defend a currency peg?

They buy or sell foreign reserves, adjust interest rates, or implement capital controls.

What risks do investors face with pegged currencies?

Devaluation risks, capital control restrictions, and sudden policy changes can impact investments.

Does a pegged exchange rate affect exports?

Yes, an overvalued peg can make exports expensive, while an undervalued peg can boost export competitiveness.

Are pegged exchange rates sustainable long term?
