A currency peg is an official policy that fixes a country’s exchange rate to another currency — usually the US dollar or the euro — at a set rate or within a narrow band, held in place by its central bank. A peg removes day-to-day swings against the anchor currency. But if you are sending pounds, the amount your recipient receives can still move — because your transfer travels through that anchor.
That distinction is the single most useful thing to understand before sending money to the Gulf, Hong Kong, Denmark or China. This guide explains what a peg is, which currencies are pegged or managed, and why “pegged” does not mean your transfer is protected.
What is a currency peg?
A currency peg is a commitment by a central bank to keep its currency at a fixed value against an anchor currency, either at an exact rate or inside a defined band. The central bank defends the peg by buying and selling foreign-exchange reserves and by aligning its interest rates with the anchor economy.
Most pegs use the US dollar as the anchor, because so much global trade — oil, in particular — is priced in dollars. A smaller group anchors to the euro. The pound, the dollar, the euro, the yen and the Australian dollar, by contrast, all float freely: their value is set by the market minute to minute, with no official target.
The International Monetary Fund classifies every country’s arrangement along a spectrum, from hard pegs and currency boards through crawling and managed floats to free floats. Knowing where a currency sits on that spectrum tells you how much its rate can move — and where the movement comes from.
What are the main types of exchange rate regime?
There are four broad categories, and the practical difference for a transfer is how much the currency can move against its anchor — and against the pound.
| Regime | What it fixes | How it is held | Movement against the anchor | Example |
|---|---|---|---|---|
| Hard peg | An exact rate to one anchor currency | Central-bank reserves and matched interest rates | Effectively none | UAE dirham, Saudi riyal (to USD) |
| Currency board | A rate inside a tight guaranteed band | Full reserve backing; automatic intervention at the band edges | Very small, capped by the band | Hong Kong dollar (to USD) |
| Managed float | A daily reference rate plus a trading band | Central bank sets the fixing and can intervene | Limited each day, can drift over time | Chinese renminbi (to USD) |
| Free float | Nothing — the market sets it | No target; policy affects it only indirectly | Unlimited | Pound, US dollar, euro, yen |
A pegged currency, then, is not the same as a stable transfer. It is stable against its anchor. Whether it is stable against your money depends entirely on how the pound moves against that same anchor — which you can track on our live exchange rates page.
Which major currencies are pegged or managed?
Several currencies that UK buyers, expats and businesses deal with regularly are pegged or actively managed rather than freely floating.
- UAE dirham (AED): pegged to the US dollar at 3.6725 since 1997, maintained by the Central Bank of the UAE. This is why the dirham does not swing against the dollar — and why the UAE dirham is pegged to the dollar shapes every dirham transfer.
- Saudi riyal (SAR): pegged to the US dollar at 3.75, maintained by the Saudi Central Bank (SAMA). Qatar, Oman and Bahrain also anchor their currencies to the dollar.
- Hong Kong dollar (HKD): run under a currency board, the Linked Exchange Rate System, in which the Hong Kong Monetary Authority guarantees convertibility between 7.75 and 7.85 per US dollar, around a central link of 7.80 set in 1983.
- Danish krone (DKK): fixed to the euro under the ERM II mechanism, around a central rate of 7.4604 krone per euro, which Danmarks Nationalbank keeps far tighter in practice.
- Chinese renminbi (CNY): a managed float, in which the People’s Bank of China sets a daily central parity against the dollar and lets the onshore rate move within 2% either side.
Because most of these anchor to the dollar, the rate that actually decides your transfer is usually the GBP/US dollar rate. For the euro-anchored krone, it is the pound-to-euro rate instead.
Does a currency peg protect your transfer from exchange rate movements?
No — not if you hold pounds. A peg fixes the pegged currency to its anchor, not to sterling. When you send pounds to a dollar-pegged country, your money is effectively converted through the dollar, so the amount that lands moves with the pound-to-dollar rate even though the local currency never budges against the dollar.
A worked example makes the point. Assume the dirham’s structural peg of 3.6725 to the dollar, and take two illustrative pound-to-dollar levels.
- Sending £400,000 at an illustrative 1.30 gives $520,000, which converts at the peg to AED 1,909,700.
- Sending the same £400k at an illustrative 1.25 gives $500,000, which converts at the peg to AED 1,836,250.
The difference is AED 73,450 — around 3.8% — on a transfer to a currency that is supposedly “fixed”. Every penny of that swing came from the pound-to-dollar leg, not from the dirham. The peg guarantees the dollar-to-dirham conversion; it does nothing for the pound-to-dollar journey your money has to make first. The same logic applies to a large UK–UAE transfer and to sending money to the United States itself.
Why can money sent to a pegged-currency country arrive worth less than expected?
Beyond the pound-to-dollar cross, a second cost hides inside the route the payment takes. Sterling rarely converts straight into a pegged currency. It is often changed first into US dollars, then from dollars into the local currency — two conversions rather than one.
Each conversion can carry its own margin. If a provider takes, say, 1% on the pound-to-dollar leg and another 1% on the dollar-to-dirham leg, the second margin alone costs roughly AED 19,000 on a £400k transfer — money lost purely to the extra hop. This is the same mechanism that can make a payment arrive in the wrong currency, and it is worth checking before funding an overseas bank account. The chain lengthens further when several correspondent banks route the payment between countries, each potentially deducting a fee.
A specialist can quote the pound-to-local-currency cross as a single price, so the pricing you see is the pricing you get, rather than two hidden conversions stacked on top of each other.
Can a currency peg change or break?
Yes. A peg is a policy choice, not a law of nature, and central banks can re-set, widen or abandon one. History offers clear examples: the Swiss National Bank removed its cap against the euro in January 2015, sending the franc sharply higher within minutes, and managed-float bands have been widened more than once as economies open up.
Long-standing pegs such as the dirham, riyal and Hong Kong dollar have held for decades, but no peg can be assumed permanent. For a large or forward-dated transfer, the realistic risk to plan around is not the peg itself but the pound-to-anchor cross you are exposed to in the meantime — which you can monitor through our currency forecasts or model on the currency converter.
Common mistakes when sending money to a pegged-currency country
- Assuming “pegged” means “protected”. The peg fixes the local currency to its anchor, not to your pounds.
- Ignoring the pound-to-dollar rate. For a dollar-pegged currency, that cross is what actually decides how much arrives.
- Letting the payment double-convert. Two conversions can mean two margins; ask whether you are being quoted the direct cross.
- Treating the peg rate as your rate. The peg (for example 3.6725) is the official anchor between two currencies, not the pound-based rate you will be dealt.
- Assuming the peg can never move. Pegs are durable but not guaranteed, and a re-set can move a rate suddenly.
How a specialist broker helps with a pegged-currency transfer
Because the real variable is the pound-to-anchor cross, the tools that help are the same ones used for any large transfer: quoting the direct cross, fixing a rate ahead of a known payment with a forward contract, and timing the exchange around the pound rather than the peg. A specialist deals the cross as one price and handles the compliance so the payment is not held up in transit.
At Cambridge Currencies, client funds are safeguarded through our FCA-authorised payment partners, Currencycloud and ScioPay. Every transaction is completed by phone with a dedicated specialist who talks through the route and the rate with you before anything moves.
Frequently asked questions
Is the UAE dirham fixed to the pound?
No. The dirham is fixed to the US dollar at 3.6725, not to sterling. The pound-to-dirham rate therefore floats in line with the pound-to-dollar rate, so a dirham transfer is only as stable as the pound is against the dollar.
Do I get the peg rate when I send money?
No. A peg such as 3.6725 dirham to the dollar or 3.75 riyal to the dollar is the official anchor between those two currencies. When you send pounds, you receive a pound-based market rate, from which any margin and fees are taken.
Which currencies are pegged to the US dollar?
The UAE dirham and Saudi riyal are pegged to the dollar, as are the Qatari riyal, Omani rial and Bahraini dinar. The Hong Kong dollar is linked to the dollar within a guaranteed band of 7.75 to 7.85 under its currency board.
Is the euro pegged to anything?
No. The euro floats freely against the pound and the dollar. However, the Danish krone is pegged to the euro under the ERM II mechanism, so a krone transfer moves with the pound-to-euro rate rather than the pound-to-dollar rate.
Can a pegged currency still lose value against the pound?
Yes. A pegged currency holds its value against its anchor, but its value against the pound moves with the pound-to-anchor rate. If the pound strengthens against the dollar, a dollar-pegged currency buys fewer pounds, and vice versa.
Are forward contracts useful for a pegged-currency transfer?
They can be. A forward contract fixes the pound-to-anchor cross you are exposed to for up to 12 months, which removes the uncertainty on the leg that actually moves. For a known future payment to the Gulf or Hong Kong, that can bring certainty to the cost in pounds. Our specialists can talk through whether it fits your situation.
Where can I see how the pound is moving against a pegged currency?
Track the anchor cross rather than the peg. For dollar-pegged currencies, watch the pound-to-dollar rate; for the Hong Kong dollar, the pound-to-Hong Kong dollar outlook follows the same driver. Live rates and forecasts show where the pound sits against each anchor.
