When I opened my first restaurant opposite Angkor Wat at 16, people were still trading in gold. After the Khmer Rouge, Cambodia had no functioning currency. We used Vietnamese dong, gold, and rice before the dollar took over. Two decades later, I can scan a QR code at a noodle stall in Siem Reap and pay from my phone in seconds. Cambodia’s money story is changing fast, and most travel guides haven’t caught up.
This guide covers exactly what you need to know before you arrive: which currency to carry, which ATMs to use, what digital payments work, and the practical details that save you from awkward moments at the checkout.
- Dual currency: USD for anything over $10-20. Cambodian Riel (KHR) for small change. Exchange rate: ~4,000 KHR = $1.
- Bring clean bills: Crisp $50s and $100s from home. ATMs dispense only $100 bills in USD. Small denominations ($1-$5) are being phased out.
- Best ATM: BRED Bank ($4 fee, up to $2,000 per withdrawal). Avoid ABA for foreign cards.
- Digital payments: KHQR codes accepted at 4.9 million merchants. The Bakong Tourist App works without a Cambodian bank account.
- Buy your Angkor pass online: Angkor Enterprise accepts cards. Soft copy on your phone.
The Dual Currency System
Cambodia runs on two currencies simultaneously, and it is simpler than it sounds. The US dollar handles anything above $10-20: hotels, restaurants, tours, visa fees, supermarkets. The Cambodian Riel handles everything below: tuk-tuks, market snacks, bottled water, street food. You do not need to think about which to use. The situation presents itself naturally.
The exchange rate sits at approximately 4,000 KHR to 1 USD and has barely moved in years. The 52-week range is 3,974 to 4,054 (National Bank of Cambodia). In practice, vendors round to 4,000. All change below $10 is given in Riel. If something costs $3 and you pay with a $10 bill, you will receive 28,000 Riel back. That is normal, and the math is simple: $7 x 4,000 = 28,000. Do not try to exchange Riel before your trip. It cannot be obtained outside Cambodia and cannot be exchanged when you return home. Let it accumulate naturally as change, and spend it before you leave.
There is no plan to eliminate the US dollar. The National Bank of Cambodia is gradually increasing Riel usage through digital payments, but USD remains dominant for larger transactions. For travelers, nothing changes: bring dollars, receive Riel as change.
Which Bills to Bring
Bring crisp, undamaged $50 and $100 bills from home. This is the single most practical piece of currency advice for Cambodia. ATMs now dispense only $100 bills in USD, so arriving with a mix of $20s and $50s gives you flexibility that the machines cannot.
Small-denomination bills ($1, $5) are being phased out by the National Bank of Cambodia (Cambodianess). Banks no longer issue them and many merchants prefer not to handle them. The $10 and $20 bills remain useful for day-to-day spending, but $50s and $100s are what you will need for hotels, tours, and larger purchases.
Dollar bills must be in good condition. In 2025, Prime Minister Hun Manet instructed banks to accept slightly marked notes without penalties (Khmer Times). Light creases and minor stains are now more widely accepted. However, torn, taped, or heavily written-on bills are still routinely refused. Ask for clean, post-2006 series notes at your bank before you travel.
Exchanging Money
Arriving with US dollars is the simplest strategy. If you are traveling from Europe or Australia, the exchange rate inside Cambodia is typically better than what you would get at home. Skip the airport exchange counters, where rates are noticeably worse. In Siem Reap, the best rates are at exchange shops inside Phsar Leu market and along the Old Market area. They are easy to spot: currencies displayed in glass cabinets at the entrance.
Do not exchange USD into Riel directly. You will receive Riel naturally as change throughout your stay. Exchanging directly gives you a worse rate and more notes to manage.
ATMs: Which Bank, What to Expect
ATMs are widely available in Phnom Penh and Siem Reap. Every one of them charges a fee on top of whatever your home bank charges. The differences between banks are significant, especially if you plan to withdraw larger amounts.
| Bank | Fee | Max Withdrawal | Notes |
|---|---|---|---|
| BRED Bank | $4 | $2,000 | Best for larger withdrawals. One transaction covers a full trip. |
| PPCBank | $5 | $1,000 | Reliable, consistent pricing. |
| Canadia Bank | $5 | $500 | Widely available across Cambodia. |
| Acleda Bank | ~$5 | Varies | Good for smaller denominations in KHR. |
| ABA Bank | $4-$8 | $500-$800 | Most locations, but foreign Mastercard fees can reach 3%. Use Visa. |
BRED Bank is the clear choice for travelers who prefer fewer transactions. One withdrawal at $4 covers what might cost $20-30 in fees across multiple withdrawals. In rural areas, on islands like Koh Rong, and in most provincial towns, ATMs are scarce or nonexistent. Withdraw enough cash before you leave the city.
Digital Payments and KHQR
This is where Cambodia has surprised everyone. The country’s digital payment system, built on the National Bank of Cambodia’s Bakong platform, processed 1.33 billion transactions in 2025 (Phnom Penh Post). That is in a country of 17 million people. KHQR codes, Cambodia’s unified QR payment standard, are now accepted at 4.9 million merchant locations, from hotel lobbies to noodle stalls.
For visitors, the practical tool is the Bakong Tourist App, launched by the central bank in 2024 specifically for foreign travelers (Phnom Penh Post). You do not need a Cambodian bank account. Download it from Apple App Store or Google Play, load it with funds, and scan KHQR codes at participating merchants. It also works cross-border if you are continuing to Thailand, Vietnam, or Malaysia.
Beyond KHQR, most hotels, restaurants, and tour operators in Phnom Penh and Siem Reap accept Visa, Mastercard, Apple Pay, and Google Pay. At Adventures Cambodia, you can book and pay online, or settle on-site by card. In rural areas and on islands, cash remains the only reliable option.
Carry cash as your primary method and treat digital payments as a convenient backup. The KHQR system works well in Siem Reap’s restaurants and shops, but you will still need dollars for tuk-tuks, smaller vendors, and anything outside the city. A mix of $300-500 in clean bills plus a working card covers most trips comfortably.
Tipping in Cambodia
Tipping is not traditionally part of Cambodian culture, but it is appreciated in the tourism industry. There are no firm rules, but here is what works well:
- Restaurant staff: 10% or round up the bill. Most restaurants do not add a service charge.
- Tuk-tuk drivers: Round up to the nearest dollar on short rides. $2-5 extra for a full day.
- Temple guides: $10-20 for a full-day licensed guide, depending on group size.
- Hotel housekeeping: $1-2 per night, left on the pillow or nightstand.
- Spa therapists: $3-5 for a good treatment, more for exceptional service.
Tip in USD for anything over $2, in Riel for smaller amounts. Do not tip with coins of any currency. Cambodian businesses rarely handle foreign coins, and there is no practical way to use or exchange them here.
FAQ: Cambodia Currency
What is the official currency of Cambodia?
The Cambodian Riel (KHR). However, the US Dollar is the dominant currency for most transactions above $10-20. Hotels, tours, and restaurants price in USD.
Do I need US dollars in Cambodia?
Yes. Most prices are listed and paid in USD. Bring clean $20, $50, and $100 bills. You will receive Riel as change for amounts under a dollar.
What is the USD to KHR exchange rate?
Approximately 4,000 KHR to 1 USD. The rate is remarkably stable, with a 52-week range of just 3,974 to 4,054. Check the daily official rate at the National Bank of Cambodia.
Can I get Riel before traveling to Cambodia?
No. Riel is only available inside Cambodia and cannot be exchanged internationally. You will accumulate it naturally as change from USD transactions.
Are damaged US dollar bills accepted in Cambodia?
Slightly marked bills are now more widely accepted following a 2025 government directive. Badly torn, taped, or heavily written-on bills remain refused. Always bring clean, undamaged notes.
Are ATMs easy to find in Cambodia?
Yes, in Phnom Penh, Siem Reap, and Sihanoukville. ATMs charge $4-6 per withdrawal and dispense $100 bills in USD. In rural areas and on islands, ATMs are rare. Withdraw cash before leaving the city.
Can I pay by card or mobile in Cambodia?
Yes, in major cities. Most hotels and tour operators in Phnom Penh and Siem Reap accept Visa, Mastercard, Apple Pay, and Google Pay. The Bakong Tourist App lets you scan KHQR codes at millions of merchants without a Cambodian bank account. In rural areas, cash is still required.
Do I need to worry about running out of cash?
Not in Siem Reap or Phnom Penh. ATMs, card payments, and KHQR are widely available. Carry a comfortable amount in clean bills for flexibility, and use BRED Bank if you need a top-up. The only time cash planning matters is if you are heading to islands or rural provinces where ATMs are scarce. In that case, withdraw what you need before leaving the city.
