You land in Phnom Penh, and the first thing you see at the airport ATM is a choice that feels like a trick. Do you want your cash in US Dollars (USD) or Cambodian Riel (KHR)?
Most travelers instinctively reach for the greenbacks. It’s what we know. It feels safe. But honestly, if you’re still treating Cambodia like a 100% dollarized economy, you’re basically burning money and begging for a headache at the checkout counter.
The relationship between the american dollar to cambodian riel is shifting. Fast.
What used to be a simple "four thousand riel to a buck" rule of thumb has turned into a nuanced game of digital wallets, pristine paper, and a government that's subtly trying to push the dollar out the door. If you want to navigate Cambodia in 2026 without getting stuck with a useless $100 bill or losing 5% on every street food snack, you’ve got to understand how this dual-currency dance actually works.
The Death of the Small Dollar
For decades, the $1, $2, and $5 bills were the lifeblood of Cambodian tourism. You’d tip your driver with a single and buy a beer with a five.
Those days are over.
The National Bank of Cambodia (NBC) has been on a mission to "de-dollarize" the small stuff. Today, if you try to hand a $1 bill to a vendor at a market in Siem Reap, they might just look at you and shake their head. Banks have largely stopped issuing small-denomination USD, and merchants don't want the hassle of trying to deposit them.
Basically, for anything under $10, the Cambodian Riel is now king.
The exchange rate usually hovers around 4,000 to 4,050 KHR per 1 USD. If you pay with a $10 bill for a $3 coffee, expect your change to come back entirely in riel. Don't be that person who gets annoyed by it—it’s just how things work now.
The "Pristine Bill" Obsession is Real
This is the part that drives Westerners crazy.
In the States, you can tape a ripped $20 bill back together and the grocery store will take it. In Cambodia? A microscopic tear or a tiny ink stain on a $50 bill makes it "dead."
I’m not exaggerating. I once saw a high-end hotel refuse a $100 bill because it had a tiny fold in the corner that wouldn't flatten out. They aren't being rude. Cambodian banks are incredibly strict with the NBC, and if a business can't deposit the bill, they won't take it from you.
If you're bringing cash, it needs to look like it just came off the printing press. Crisp. Flat. Brand new.
On the flip side, Cambodian Riel notes can be as dirty, crumpled, and taped-up as you like. Nobody cares. This is one of the biggest practical advantages of using the local currency—the stress of keeping your money "perfect" simply disappears.
Bakong: The Digital Revolution Nobody Expected
While everyone was debating paper bills, Cambodia quietly built one of the most advanced digital payment systems in the world.
It’s called Bakong.
You’ll see KHQR codes (pink and blue stickers) on everything from five-star hotel desks to the side of a sugarcane juice cart. It’s a blockchain-based system that allows for instant payments in both USD and KHR.
For a long time, this was only for locals with Cambodian bank accounts. But in late 2024 and throughout 2025, the Bakong Tourists App really took off. You can now download the app, link an international card (like Visa or Mastercard), and pay just like a local.
Why does this matter for the american dollar to cambodian riel exchange?
Because when you scan a code, the app often handles the conversion for you at the official rate. No more mental math at 11:00 PM trying to figure out if 17,500 riel is a fair price for a tuk-tuk. You just scan, and it’s done.
The ATM Trap
ATMs in Cambodia are a bit of a mixed bag. Most of them—especially those from big players like ABA Bank or Canadia—will give you the option to withdraw USD or KHR.
Here is the catch: almost every ATM that gives USD will only spit out $100 bills.
Think about that. You’re in a country where a delicious bowl of Nom Banh Chok costs $1.50, and you’re walking around with a $100 bill that must remain "pristine" to be valid. It’s a recipe for disaster.
If you withdraw $500 in USD, you now have five high-stress pieces of paper that most small shops can't even change. If you withdraw the equivalent in Cambodian Riel, you’ll get a thick stack of 50,000 and 20,000 notes. It feels like "Monopoly money" at first, but it’s infinitely more spendable.
Which Currency Should You Actually Use?
It's not an all-or-nothing thing. You need both.
Large purchases—boutique hotels, high-end dinners, or your Angkor Wat pass—are still priced and paid for in USD. It’s just easier for big numbers.

But for the "real" Cambodia? The street food, the local markets, the rural guesthouses? Riel is your best friend.
Pro Tip: If a price is quoted in Riel, pay in Riel. If you try to pay in Dollars for a Riel-priced item, the vendor will usually round the exchange rate up to their advantage (often 4,200 or 4,500 KHR per dollar) to cover their own trip to the money changer. You’ll lose a few cents here and there, and over a two-week trip, that "foreigner tax" adds up to a couple of nice dinners.
Smart Moves for Your Money
Instead of stressing about the american dollar to cambodian riel rate every morning, just follow these rules of thumb:
- Check your bills at the border: If you're bringing USD cash, inspect every single note. If it has a mark, spend it at the airport before you leave your home country.
- Download Bakong: Before you leave the airport, get the Bakong Tourists app set up. It’s the easiest way to avoid the "pristine bill" drama and the "no change" problem.
- Carry a "Daily Stash" of Riel: Keep about 100,000 Riel (roughly $25) in your pocket for small stuff. It makes life so much smoother when dealing with tuk-tuk drivers or buying water.
- Use the 4,000 rule for quick math: If you see 20,000 Riel, just divide by 4. It's five bucks. Close enough for a quick decision.
- Say no to damaged change: If a vendor tries to give you a torn US dollar bill as change, politely ask for a different one or ask for the change in Riel instead. Once that torn dollar is in your wallet, it’s your problem.
The dual-currency system is a quirk of history, a remnant of the UN intervention in the 90s, but the country is moving on. By embracing the Riel and the new digital tools, you’re not just saving money—you’re participating in the local economy the way it’s actually moving in 2026.
Your Action Plan:
- Step 1: Call your bank and tell them you're traveling to Cambodia so they don't freeze your card at the first ATM.
- Step 2: Request "new series" $20 and $50 bills if you're taking cash.
- Step 3: Upon arrival, use an ABA Bank ATM to withdraw a mix of KHR for daily use and keep your USD for the "big" stuff.
