So, you’ve just come back from a whirlwind trip through the limestone karsts of Ha Long Bay or the chaotic, beautiful streets of Hanoi. You’ve probably got a thick stack of colorful polymer notes sitting in your wallet, feeling like a literal millionaire. Then you look at the exchange rate for Vietnam Dong to SGD and reality hits. That 500,000 VND note? It’s basically the price of a decent lunch in the Singapore CBD.
It’s a weird feeling.
Handling the Dong is confusing because of all those zeros. Honestly, it’s the only place where you can spend a "million" on a casual dinner and not even blink. But when it comes to turning that leftover cash back into Singapore Dollars—or if you're a business owner moving money between the two countries—the math gets tricky fast.
The Math Behind Vietnam Dong to SGD
Right now, in early 2026, the rate is hovering somewhere around 0.000049.
Yeah, you read that right. Four zeros.
Basically, 1,000,000 VND is roughly equivalent to 49 to 50 SGD, depending on the day and who is taking a cut. If you're standing at a money changer at The Arcade or Lucky Plaza, they aren't going to give you that mid-market rate you see on Google. They have bills to pay and staff to salary, so expect to lose a couple of percentage points in the "spread."

Why the Rate Is So "Low"
People often ask if the Vietnamese currency is "weak" because of the high numbers. It’s not necessarily about weakness; it’s about history and denomination. Vietnam hasn't done a "re-denomination" (where they just chop off the zeros) like some other countries have. They’ve stuck with the large numbers.
For a Singaporean traveler, this creates a specific kind of "math fatigue." You're constantly dividing by roughly 17,000 or 18,000 in your head to find the SGD value, but the official rate is much tighter.
Where to Exchange Vietnam Dong to SGD Without Getting Ripped Off
If you're in Singapore and sitting on a pile of cash, you've got a few solid options.
1. The Arcade (Raffles Place)
This is the holy grail for currency exchange in Singapore. Because there are so many shops crammed into one building, the competition is fierce. They have to keep their Vietnam Dong to SGD rates sharp just to survive.
- Arcade Plaza Traders (Unit #02-03) is usually a safe bet.
- People's Corner (#02-07) often has decent stock of regional currencies.
Pro tip: Don't just go to the first one you see. Walk one full lap of the second floor. Sometimes the shop tucked in the corner has a rate that's a fraction better, and on a few million Dong, that adds up to a free kopi.
2. Lucky Plaza or People's Park Complex
If you're already in Orchard or Chinatown, these are your go-to spots. People's Park Complex is particularly good for Southeast Asian currencies. Changers like Crante or Today’s Money Exchange are staples there.
3. Mustafa Centre
Mustafa is the only place that's consistently there for you at 2:00 AM. While their rates for Vietnam Dong to SGD might not be the absolute best in the city, the convenience is unbeatable. If you're flying out at dawn and realized you forgot to change your money, Mustafa is your best friend.
Watch Out for the "Blue Note" Trap
One of the most common mistakes people make when handling Vietnamese money is confusing the 20,000 VND note with the 500,000 VND note.

They are both blue. Sorta.
The 500k note is a slightly more cyan/green-blue, while the 20k is a deeper, darker blue. When you're in a rush at a busy market or a dim bar, it is incredibly easy to hand over 500,000 instead of 20,000. In Singapore Dollar terms, that's like trying to pay with a $2 note and accidentally handing over a $50 bill.
Always check the zeros.
Moving Money Digitally (The 2026 Way)
If you aren't dealing with physical cash, please, for the love of everything, don't use a traditional bank wire if you can avoid it. The fees will eat you alive.
For sending Vietnam Dong to SGD (or vice versa), fintech has basically won the war. Platforms like Wise, Revolut, and Airwallex use the interbank rate. This is the "real" rate you see on news tickers.
Regulation Reality Check
Vietnam has pretty strict rules about moving currency out of the country. According to the State Bank of Vietnam, if you're carrying more than 15,000,000 VND (or $5,000 USD equivalent) across the border, you have to declare it.
The government recently tightened things up even more. Decree 340/2025, which kicked in fully by February 2026, introduced much heavier fines for unauthorized currency trading. If you’re a business owner, make sure you’re using licensed channels. The days of "informal" transfers at gold shops are getting riskier and the fines can now reach up to 100 million VND for individuals.

Did you know that Vietnamese coins are basically extinct?
Technically, the State Bank minted coins in 2003 (200, 500, 1,000, 2,000, and 5,000 denominations). But they were so unpopular and lost value so fast due to inflation that you almost never see them today. If you find one, keep it as a souvenir. It’s worth more as a conversation piece than for actually buying a Banh Mi.
Another thing: The Polymer Factor.
Vietnam was one of the first countries to go all-in on polymer (plastic) notes for everything over 10,000 VND. They are waterproof. You can literally go swimming with them in your pocket at a beach in Da Nang, and they’ll be fine. Just don't iron them. They will melt.
Actionable Steps for Your Currency Exchange
If you want the most bang for your buck, here is exactly what you should do:
- Use the "K" Rule: In Vietnam, "50k" means 50,000. Just ignore the last three zeros for a second. It makes the math way less scary.
- Spend Small Notes: Change in Vietnam is often given in small paper 1,000 or 2,000 VND notes. These are basically useless once you get back to Singapore. No money changer in The Arcade is going to want to count a mountain of 1,000 VND notes. Spend them on the street or leave them as a tip before you head to the airport.
- Check for Tears: Money changers in Singapore can be incredibly picky. If your 500,000 VND note has a tiny tear or a significant ink stain, they might refuse it or offer a "damaged" rate which is much lower. Keep your big notes crisp.
- Use Multi-Currency Cards: If you’re going the other way (SGD to VND), get a YouTrip or Trust card. You’ll get the mid-market Vietnam Dong to SGD rate directly at the ATM or at the card terminal in the mall. It beats carrying a brick of cash any day.
Most people get stressed about the big numbers, but once you realize that 100,000 VND is just a fancy coffee and a cake in Singapore, the scale starts to make sense. Watch the rates, avoid the airport changers if you can, and always, always double-check your blue notes.
