Understanding Cambodia’s Currency in 2025: A Traveler’s Guide to Riel, US Dollars, and Modern Payments
Cambodia’s currency situation is unique. Unlike its neighbors, where the local currency dominates, Cambodia operates on a dual-currency system, with the Cambodian Riel (KHR) and US Dollar (USD) co-existing in daily transactions. While this may seem confusing at first, it’s actually quite convenient for travelers. Whether you’re buying street food in Phnom Penh, shopping in Siem Reap, or withdrawing cash from an ATM in Sihanoukville, knowing how the local currency works can save you money and make your trip smoother.
Riel vs. US Dollar: How Cambodia’s Currency Works
The Cambodian Riel (KHR) – The Official Currency
The Riel (៛) is Cambodia’s official currency, with an exchange rate of approximately 4,100 Riel to 1 USD in 2025. While locals use Riel for smaller transactions, you’ll often receive Riel as change when paying in USD. However, you won’t find Riel available for exchange outside of Cambodia, so it’s best to use up any leftover Riel before leaving.
The US Dollar – Cambodia’s Second Currency
The US Dollar has been widely accepted in Cambodia for decades, particularly for larger purchases such as hotel stays, tours, and entry tickets to Angkor Wat. Many businesses even price their goods and services in USD. However, with recent economic changes, Cambodia has started moving toward greater reliance on the Riel. This means small USD notes ($1 and $5 bills) are gradually being phased out, and customers are expected to use Riel for minor purchases.
Exchanging Money in Cambodia
Currency exchange in Cambodia is simple and widely available. Exchange offices are common in city markets and offer better rates than airport kiosks or hotels. If you’re arriving with USD, you don’t need to exchange for Riel upfront—you’ll naturally receive it as change when making purchases.
Key tips for exchanging money:
- Avoid exchanging at airports—their rates are often less favorable.
- Check your US bills carefully—torn or damaged notes are sometimes rejected.
- Bring larger USD bills ($10, $20, $50, $100)—smaller notes are becoming rare.
New Rules on Small & Damaged USD Bills
A big change in Cambodia’s financial system is the phasing out of $1 and $5 USD notes. If you pay in USD for something under $10, expect to receive change in Riel.
Another improvement is the recent acceptance of damaged or tinted US bills in Siem Reap, where banks are now required to accept them. Previously, businesses refused damaged notes, and tourists often struggled to spend them. While this is great news, it’s still best to carry crisp, undamaged notes to avoid complications.
ATMs in Cambodia
ATMs are widely available in major cities like Phnom Penh, Siem Reap, and Sihanoukville. However, if you’re heading to remote areas or islands like Koh Rong, it’s best to withdraw cash in advance. ATM withdrawal fees in Cambodia range from $3 to $6 per transaction, so taking out larger amounts at once can help save on fees.
Digital Payments: Cambodia’s Growing Trend
Cash may still be king in Cambodia, but digital payments are on the rise, particularly in major cities. While you won’t find Apple Pay, Google Pay, or Alipay everywhere, mobile payment apps such as ABA Bank, Wing, and Pi Pay are increasingly accepted in restaurants, cafés, and some retail stores.
If you’re booking tours or shopping in Siem Reap or Phnom Penh, check if businesses accept credit cards or mobile payments—it’s becoming more common. However, always carry some cash, as digital payments are still rare in rural areas.
Traveler’s Money Tips for Cambodia
- Carry both USD and Riel—Use Riel for small purchases and USD for larger ones.
- Pay in Riel when the price is under $10—You’ll often get a better rate.
- Don’t bother exchanging USD to Riel—You’ll naturally receive Riel as change.
- Use $10, $20, or $50 USD bills—Larger notes are preferred.
- Avoid torn or damaged USD bills—They may still be rejected outside Siem Reap.
- Withdraw cash before heading to remote areas—ATMs are scarce outside cities.
Final Thoughts
Cambodia’s dual-currency system might seem unusual, but it’s actually very traveler-friendly. Whether you’re exploring ancient temples, relaxing on a tropical island, or shopping in local markets, knowing how to handle Riel and USD will make your trip stress-free. And with mobile payments on the rise, Cambodia is becoming even more accessible to modern travelers.So, pack your crisp USD bills, keep some Riel in your pocket, and enjoy your time in the Kingdom of Wonder!
