What is a Pegged Currency?

A pegged currency, also known as a fixed exchange rate or currency peg, is a monetary system in which a country's central bank is deliberately tied to another currency, basket of currencies or gold at a fixed rate.¹

It involves the central bank committing to buy or sell its own currency at the fixed rate to ensure stability.

Let’s take a look at how Barbados pegs their currency. The Bajan or Bahamian dollar is a pegged currency that is always tied to the value of the US dollar. So if the country’s government says that 2 of their currency is always worth 1 US dollar, then no matter what happens in the world, their currency's value stays the same relative to the dollar.

So, if you go to Barbados, you know exactly how much your money is worth compared to the US dollar which in this case is 2 BBD to 1 USD.

Of course not all currencies are pegged and while pegged rates are managed by the government, floating currencies rise and fall based on market demand.

Why do countries peg their currency

Countries often peg their currency to achieve economic stability.² This can help control inflation, especially in countries with a history of currency devaluation.

It also simplifies international trade and investment, protecting it to ensure currency values stay predictable³ and to remove the uncertainty of exchange rate fluctuations with their main trading partners to boost investor confidence.

How a pegged currency works

To maintain a peg, a country's central bank must actively manage its currency's value in the foreign exchange market.⁴

If the currency weakens, the central bank will buy its own currency using its foreign reserves (like USD or EUR) to push its value back up.

On the other hand, if it strengthens too much, the bank may sell its currency to bring it down.

Types of pegged exchange rate systems

Pegs aren't one-size-fits-all. Some are hard pegs, like currency boards or dollarisation, where the currency is essentially replaced.⁴

Others are known as soft pegs, which allow for some fluctuation within a narrow band¹.

There are also crawling pegs, where the fixed rate is adjusted periodically, often to account for inflation differences. By making small, slow changes to the currency target, a country can stay competitive without the sudden shock of a major devaluation.⁴
In the world of pegged currencies, the mid-market rate is especially powerful because it acts as a transparent "North Star." Since the government fixes a currency’s value to an anchor (like the US Dollar), the mid-market rate stays relatively predictable unless the central banks decide to change the pegged rate, which can happen frequently.

The mid-market rate is a great benchmark for consumers and businesses as it acts as the exact halfway point between what banks buy and sell a currency for. By comparing a bank’s offered rate to the official mid-market peg, you can see exactly how much of a "hidden fee" or exchange rate markup the bank is pocketing.

Wise uses the mid-market rate and is upfront about fees* so depending on the currency route, it could save you money.

• Bahrain (1 USD = 0.376 BHD)
• Hong Kong (1 USD = 7.80 HKD ±0.05)
• Oman (1 USD = 0.385 OMR)
• Qatar (1 USD = 3.64 QAR)
• Saudi Arabia (1 USD = 3.75 SAR)
• United Arab Emirates (1 USD = 3.67 AED)⁵

Impact of pegged currency on the UK

While the UK currency isn’t pegged, let’s imagine it was and explore the impacts it might have.

Potential impact on the UK's financial landscape

If the UK were to peg the GBP, it would fundamentally alter its financial landscape. The Bank of England would lose significant control over monetary policy¹, with interest rates often needing to mirror those of the anchor currency country.⁴ This could impact borrowing costs, inflation, and overall economic growth strategies.

How pegged currencies affect UK consumers

For consumers, a pegged GBP could mean more stable prices for imported goods from the anchor country.

However, if the anchor currency strengthens significantly against other global currencies, imported items from elsewhere could become more expensive. It also affects the cost of travel and overseas purchases.

The implications for UK businesses and international trade

UK businesses trading internationally would benefit from predictable exchange rates with the pegging partner, simplifying invoicing and financial planning.

However, if the pegged GBP becomes overvalued against other currencies, UK exports could become less competitive globally, while imports would appear cheaper, potentially widening trade deficits.¹

Advantages and disadvantages of a pegged currency

There are pros and cons of a pegged currency and setting a currency peg is a delicate balancing act because if the price is set too low, a country’s citizens lose their "buying power" on the global stage, making essential imports like food and oil much more expensive and lowering their overall standard of living.¹

This often leads to trade tensions, as foreign producers find it harder to sell their goods into that market.

On the other hand, if a peg is set too high, it creates a false sense of wealth that leads to a "spending spree" on imports the country cannot actually afford.¹

To keep an overpriced currency from falling, the government must constantly spend its own foreign savings to prop up the value, which eventually leads to a total collapse once those reserves run out.

When a peg finally breaks, the sudden crash causes prices to skyrocket, fuels high inflation, and can leave the nation struggling to pay back its international debts, while foreign investors see the value of their holdings vanish overnight.¹

FAQs about pegged currencies

Here are some additional questions you may have about pegged currencies, answered.

What currencies are currently pegged to the US Dollar?

Several currencies are pegged to the US Dollar (USD). These include currencies like the Saudi Riyal (SAR), Emirati Dirham (AED), and Bahraini Dinar (BHD). Many other countries in regions like the Caribbean also maintain pegs to the USD.⁵

Is the Euro a pegged currency or do other currencies peg to it?

The Euro (EUR) itself is not a pegged currency. It floats freely against most other major currencies. However, some countries peg their currencies to the Euro.

What happens if a country abandons its currency peg?

If a country abandons its currency peg, its currency is likely to either devalue or revalue significantly, depending on market forces and the circumstances leading to the abandonment.¹ This can cause economic instability, inflation, and affect international trade and investment.

How does a pegged currency impact interest rates in the UK?

If the UK pegged its currency, its interest rates would likely have to follow the interest rate policy of the country whose currency it is pegged to.¹ This means the Bank of England would have less autonomy in setting rates to manage the UK's domestic economic conditions, such as inflation or unemployment.
