Before a trip to Siem Reap, you look up Cambodia’s currency and find that it’s the riel. Then a friend who has been there tells you to bring US dollars, and the first ATM you use hands out dollars, not riel. Both are true, and how the two currencies fit together decides how you pay, what change you get back and where you lose money to poor rates. This guide covers the riel, its symbol and code, why dollars circulate alongside it, and how to spend and send money in Cambodia.
The currency of Cambodia is the Cambodian riel, symbol ៛ and code KHR. In practice, US dollars are widely used across Cambodia, especially for larger purchases, while riel is often used for small change. Many prices are quoted in dollars in tourist areas.
What is the currency of Cambodia?
The currency of Cambodia is the Cambodian riel, but US dollars are used alongside it every day, so most visitors end up handling both. The riel is the national currency, and the National Bank of Cambodia is its sole issuer. The dollar isn't issued by Cambodia at all, yet it's what most ATMs dispense and what many hotels, restaurants and shops use to set their prices.
In practice, the two currencies split the work:
- US dollars cover larger payments: hotel rooms, tours, restaurant bills and most prices in cities and tourist areas.
- Riel cover small purchases such as street food and tuk-tuk rides, and they’re the everyday currency in rural areas.
There are no US coins in circulation in Cambodia, so any change smaller than a dollar comes back in riel. That's why a visitor's wallet is usually a mix: dollar notes for the main payment and a stack of riel for the change. Near the Thai border, shops may also accept Thai baht, though usually at a poor rate.
The rest of this guide covers the riel itself, how the dollar became so common, and what to do with both when you travel or send money.
The Cambodian riel: Symbol and code
The Cambodian riel uses the symbol ៛ and the ISO currency code KHR. You'll see ៛ on price lists and signs in Cambodia, while KHR is the code used by banks, exchange apps and currency converters. The National Bank of Cambodia says it is the sole issuer of the Khmer riel, the national currency.
The riel is nominally divided into 100 sen, but sen aren't used in everyday life. Riel banknotes run from 100 riel up to 100,000 riel, and because a single riel is worth so little, prices in riel are usually written in the thousands.
A US dollar buys roughly 4,000 riel, and shops commonly round to that figure when they work out change. Rates move, so check the day's rate before you exchange money. The National Bank of Cambodia describes its approach as a managed floating exchange rate, where the rate is allowed to move within a band.
That high number of riel per dollar is why the currency appears on lists of the least valuable currencies. Such a ranking only counts how many units buy one dollar. It doesn't measure how strong an economy is, and a low-value currency can reflect history, such as past hyperinflation, rather than current conditions.
Why US dollars are used in Cambodia
US dollars are used in Cambodia because people lost confidence in the riel after years of upheaval, and a large inflow of dollars in the early 1990s made the dollar the easier currency to trust and spend. The National Bank of Cambodia's own research paper on dollarisation says dollarisation did not result from a policy decision. It built up as shocks wore down trust in the riel.
Memory of that hyperinflation is why the habit lasted. The same paper put foreign currency at 97.3% of bank deposits at the end of 2006, which shows how far people had moved their savings into dollars. The central bank has since encouraged wider use of the riel, so the balance may have shifted, but the day-to-day split described above still holds for most visitors.
In practice, prices are often quoted in dollars, and you can pay in either currency. If a drink costs $2.50 and you pay with a $5 note, the change might come back as $2 and 2,000 riel, at the common rounded rate of 4,000 riel to the dollar.

If you earn or save in dollars, you can hold US dollars and other currencies in a Grey account, which keeps your trip budget in the currency Cambodia already prices in.
Money tips for travellers in Cambodia
For most trips, carry small, undamaged US dollar notes for everyday spending, a little riel for small purchases, and a card for the places that accept one. Cash is the main way to pay in much of the country, so a few habits protect you from the usual losses:
- Bring clean, untorn dollar notes. Banks, money changers and shops can refuse notes with tears or heavy marks, and larger notes are the hardest to use. Check yours before you fly.
- Carry small bills. Tuk-tuk drivers and street vendors often can't break a large note, so $1, $5 and $10 notes go further than a $50 or $100.
- Keep some riel. You'll want it for motorbike taxis, snacks and small shops, and it has little value outside Cambodia, so spend what's left before you go.
- Expect dollars from ATMs. Most ATMs dispense US dollars, often in large notes, and some charge a fee per withdrawal. Read the screen before you confirm.
- Count your change. In busy tourist areas, riel change is sometimes short. A quick check takes seconds.
- Compare money changers. Tourism Cambodia says money changers generally give slightly better rates than banks, so compare a few before you swap.
Cards work in a narrower set of places. The same source says they're accepted at upscale hotels, shops and restaurants in the major tourist towns and generally not elsewhere, and that most businesses that take cards add a fee of 2% to 4%. Ask before you pay, and keep cash as your backup.
Your own bank is the other place money leaks. Many cards add a foreign transaction fee on purchases in another currency, and how to avoid foreign transaction fees explains what to look for. Because many Cambodian prices are in dollars, a dollar card can pay those without a currency conversion, while riel prices are a different currency and may trigger a conversion or cross-border fee depending on the card.
Sending money to Cambodia
Sending US dollars is often a practical way to send money to Cambodia, as USD is widely used for everyday payments, pricing and savings. With Grey, you can send USD directly to a bank account in Cambodia via SWIFT, with a flat $30 transfer fee and limits ranging from $100 to $5,000 per transaction.
You can also send money from the US to other supported destinations, including Thailand, where Thai baht is the local currency.
Before you send, check three costs:
- The transfer fee: Grey shows its fees before you confirm a transfer.
- The exchange-rate margin: if you convert from another currency first. It's built into the rate rather than shown as a separate line.
- The receiving bank's own charges: Banks can add fees to incoming international transfers, so ask the recipient.
If you're travelling rather than sending, a Grey virtual card lets you spend from a USD balance. Grey doesn't charge a foreign transaction fee on purchases made in the card's base currency, which is USD for the virtual USD card. A cross-border card fee of 2% plus $0.50 applies to non-USD purchases, so a purchase priced in riel would carry it. Card acceptance varies by merchant, so keep some cash too.
Grey is a financial technology company, not a bank: banking services are provided by licensed banking partners.
