Currency and Money

When coming to Vietnam you will be a wealthy person, a millionaire. The exchange rate for the Vietnam Dong (VND) (at the time of writing) is at about: 1 US dollar = 23.300 VND, 1 EUR = 26.710 VND, this means 100 USD and 100 EUR are worth more than 2 million dongs. You should exchange small denominations notes as 10.000, 20.000, 50.000, 100.000 and 200.000 to be easy to spend in Vietnam.
Where to Change Your Money
Major currencies can be exchanged practically anywhere in Vietnam, but not all exchange facilities are created equal. Banks and airport money changers can change your money at a high cost relative to a jewelry shop.
Banks: The government-run Vietcombank can exchange dong for US dollars, Euros, British Pounds, Japanese Yen, Thai Baht, and Singapore dollars. Banks in major cities like Hanoi and Ho Chi Minh City will let you change foreign currencies and most travelers’ checks. You’ll be charged a commission rate of between 0.5 to 2 percent for the latter.
Always bring new notes; any damaged or dirty notes will be charged an additional two percent of the note’s face value.
Hotels: Your mileage may vary with hotels: larger hotels can offer rates competitive with banks’, but smaller hotels (like those in the Old Quarter of Hanoi) may tack on an additional fee for the service.
