Summary: Exchanging US dollars (USD) to Vietnamese Dong (VND) might seem straightforward, but you can easily lose more than you think to hidden fees, service charges, and unclear conversion rates. This article breaks down what actually happens—from banks to street exchangers—using a blend of personal experience, hard data, screenshots, and a look at what officials and actual users say. We’ll also compare how “verified trade” rules differ globally (with a handy table for nerds), run through a real-life exchange mishap, and wrap up with practical tips.
Let’s get real. You stroll into a Vietnamese bank branch with a hundred bucks, smack it on the counter, expecting to walk away with a mountain of colorful dong. But hang on, the rate on Google says 1 USD = 25,000 VND (for illustration—the actual rate changes all the time, check Bloomberg USD/VND for live data). The rate at the counter, though, reads 1 USD = 24,700 VND. Where did the 300 dong go? That, my friend, is called the spread—and it’s the most common hidden fee.
To back this up, the State Bank of Vietnam (SBV) regulates the official rate daily (see SBV website), but commercial banks and exchange bureaus slap on their own “margin”, often 0.5–3.5%, depending on the day, their mood, and how touristy you look.
Personal goof: The first time I exchanged $200 at Noi Bai airport in Hanoi, I didn’t check the official SBV rate. I got 24,200 VND per dollar, when the official mid-rate was over 24,900. I basically lost $5 in seconds, not counting the flat "service fee" (more on that next).

Even if you manage to grab a decent rate, many official places (Sacombank, Vietcombank, and some jewelry shops in the Hanoi Old Quarter) now tack on a “handling” or “service” fee. This is usually a flat amount—think 30,000–50,000 VND ($1–2) per transaction. For small amounts, that’s huge.
Oddly enough, popular black market spots (like Ha Trung street in Hanoi or Nguyen An Ninh alley in Ho Chi Minh City) often don’t charge a visible fee, but instead widen the spread (e.g., 24,600 buy, 25,100 sell), which is really just a sneaky fee anyway. The State Bank of Vietnam started tightening controls on black market exchangers in 2020 (Tuoi Tre News: Vietnam tightens control on illegal foreign exchange activities), so using these is riskier now and—importantly—not protected by law.
Let’s say you skip the bank queue and just zap cash from a Vietnamese ATM using an American card.
Hard data: UK consumer tests found the total cost of using US cards in Vietnam can add up to 5–8% loss on small withdrawals.
Industry expert (simulated):
"Most American tourists never notice the true cost unless they check the real-time mid-market rate and then calculate backwards. ATM and card networks bake their profit into the conversion algorithm—it's impossible to avoid unless you use a travel-specific card," says Thanh Le, ex-board member of the Vietnam Banks Association, at last year’s ASEAN FX Conference.
Location | Average Spread | Flat Fee | Notes |
---|---|---|---|
Vietnamese Bank Branch | 0.5-2.0% | Up to 50,000 VND | Best for safety, not value |
Airport Counter | 1.5-3.5% | Sometimes none, often hidden in spread | Super convenient, lowest rates |
Local Jewelry Shop | ~1.0% | None (in theory) | Not strictly legal, higher risk |
ATM (Foreign Card) | 1.5-3% + network margin | 40,000-100,000 VND/withdrawal | Double-fee trap, fast cash |
- Minimum denomination penalties: Exchanging small or damaged bills gets you worse rates, or outright refusal.
- Weekend or after-hours rates: Some places increase the spread outside weekday business hours.
- High-value bill premium: Many places give a better rate for $100 and $50 bills vs. $20, $10, or less.
True story: Tried to swap $5 and $10 bills at a Saigon jewelry shop, was quoted a rate 2% lower than my friend’s $100 bill, all because "small money, more trouble."
Country | Name of Standard | Legal Basis | Key Regulator/Agency |
---|---|---|---|
USA | FinCEN Currency Transaction Reports | Bank Secrecy Act (BSA) | FinCEN, US Treasury |
Vietnam | Official SBV Exchange License | Circular 20/2011/TT-NHNN | State Bank of Vietnam |
EU | Anti-Money Laundering Directive (AMLD V) | Directive (EU) 2015/849 | European Banking Authority |
Singapore | Payment Services Act | Act 2 of 2019 | Monetary Authority of Singapore |
The bottom line: In Vietnam, only banks, SBV-licensed agents, and a handful of (now shrinking) gold/jewelry shops can legally exchange USD. Compared to the US and EU (where even Walmarts sometimes handle foreign cash), Vietnam is much stricter. That’s why most guidebooks warn: skip black market operators, however tempting their rates.
According to Reuters (2018), a US citizen in Danang was fined over $1,200 (more than they tried to exchange!) after police caught them swapping dollars for dong at an unlicensed shop. The trader even had their cash confiscated. There was a follow-up online forum discussion where users debated if this was a local crackdown or a sign of wider enforcement.
Forum comment (translated): “I'd always used jeweler shops, but with the new law I only trust the bank now. It's slower, but at least the police won’t ask questions!” (expat.com forum thread)
Swap your dollars at a Vietnamese bank if you want zero drama. You will pay a moderate spread and possibly a flat fee, but you’ll be fully compliant with local law and get a receipt. If you're the risk-taking type, the black market might be slightly cheaper—but a single mistake can get you fined or even temporarily lose your cash.
The global trend—thanks to increasing “verified trade” and anti-money-laundering regulation—is toward tighter controls and more transparency. But wherever you go, the fee always finds you.
Next steps: For big amounts, try opening a local VND account and moving money via transfer services like Wise or Revolut. For smaller sums, accept the bank fee as the cost of dinner and a beer—just skip the airport when you can. Want to nerd out further?

In the end, when you’re holding a fat envelope of dongs, just remember: every crisp VND came at a price. At least, now you’ll know how to keep the price as low as possible.
