About Vikki Bank (formerly DongA Bank)

vikkibank.vn

Vikki Digital Bank is the former DongA Bank, restructured under the State Bank of Vietnam’s compulsory-transfer scheme and renamed in 2025. Its rate board lists cash and transfer buying and selling rates against the dong for 11 currencies, numbered by notice with the time of each update.

Latest board, read 16 Nov 2026, 01:38 Vietnam time (0h ago)

Bank’s own last-updated stamp: 2026-11-13 16:18:41 (as printed on its page, local time).

Board shown: Cash buy / board sell. Banks outside the Gulf publish several boards for the same currency — counter notes, drafts, transfers, cards — and this page shows one of them, the same one for every bank in Vietnam so the comparison is like for like. The others are on the bank’s own page.

Why use bank board rates through an API?

The State Bank of Vietnam official rate is what accounting, tax and customs rules name, but it is not what a customer pays at the counter or in an app. Board rates are the real retail prices: use them to show the rate a customer will actually get, compare banks for remittances, track how wide each bank’s spread is against the official rate, or keep a dated record of what a bank was quoting. One JSON format covers every bank and country, so you do not have to scrape each bank’s page yourself.

Frequently asked questions

Is the Vikki Bank (formerly DongA Bank) rate the official Vietnam exchange rate?

No. Vikki Bank (formerly DongA Bank) sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the State Bank of Vietnam; it is shown in the Official column and is the figure accounting, tax and customs rules refer to.

Which Vikki Bank (formerly DongA Bank) rate applies when I send money abroad?

The sell rate: you are buying foreign currency from the bank. When you convert foreign currency into VND, the buy rate applies. Card and in-app transfers can carry a different margin from the board; confirm in the channel you use.
