--- title: "VietABank (Viet A Bank) Exchange Rate API: VND Buy and Sell Rates as JSON" description: "VietABank (Viet A Bank)'s cash buy / board sell rates for 8 currencies against the Vietnamese dong, read hourly from the bank's own page and served as JSON with the State Bank of Vietnam official rate alongside. REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/vietabank-viet-a-bank-exchange-rate-api/ source: AllRatesToday (https://allratestoday.com/) — Markdown mirror of the page above; index of all pages at https://allratestoday.com/llms.txt generated: 2026-11-15T19:13:44.191Z --- Viet A Commercial Joint Stock Bank (VietABank) is a Hanoi-based commercial bank founded in 2003. Its exchange-rate page lists cash and transfer buying and selling rates for about 15 currencies, with US dollars split by note size. This guide shows how to read that board as JSON: what the rates mean, how they compare with the State Bank of Vietnam official rate and with other banks in Vietnam, and the calls that return them. ## What the VietABank board shows - **8 currencies against the Vietnamese dong**: AUD, CAD, CHF, EUR, GBP, JPY, SGD and USD. Every value is VND per 1 unit of the foreign currency. - **The cash buy / board sell pair.** The State Bank of Vietnam sets a daily central rate and commercial banks may quote only within a band around it, so every board moves together and the competition is in the spread. Banks publish a cash buying rate, a transfer buying rate and one selling rate; the pair shown here is the cash buy and the board sell. - **USD on 15 November 2026**: VietABank bought at 25512 and sold at 25912 VND, a spread of 1.56%. The State Bank of Vietnam official rate was 26868, so the bank's mid sat -4.30% from it. - **No timestamp on the bank's page.** VietABank does not print a last-updated time, so `bank_updated_at` is `null` and `captured_at` (when AllRatesToday read the page) is the only time available. - **Every day's board is kept permanently, from 14 November 2026.** Read one past day with `?date=`, or a range for one currency with the `/history` endpoint (paid plans). ## Spreads across the board On the 15 November 2026 board the tightest spreads were USD (1.56%), GBP (2.88%), SGD (3.00%) and the widest JPY (4.11%), CAD (3.33%), AUD (3.22%). Spread is (sell − buy) ÷ mid: what a round trip through the bank costs, before any fees. The API returns it on every row as `spread_pct`, so you can rank currencies or alert when a bank widens its board. ## USD at VietABank and other banks in Vietnam USD on the 30 boards AllRatesToday reads in Vietnam, all captured on 15 November 2026 (the State Bank of Vietnam official rate was 26868): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | Vietcombank | 25500 | 25910 | 1.59% | -4.33% | | BIDV | 25540 | 25920 | 1.48% | -4.24% | | Agribank | 25480 | 25890 | 1.60% | -4.40% | | VietinBank | 25370 | 25910 | 2.11% | -4.57% | | Nam A Bank | 25480 | 25900 | 1.64% | -4.38% | | Techcombank | 25531 | 25915 | 1.49% | -4.26% | | ACB (Asia Commercial Bank) | 25520 | 25910 | 1.52% | -4.29% | | LPBank (LienVietPostBank) | 25460 | 25870 | 1.60% | -4.48% | | SeABank | 25530 | 25910 | 1.48% | -4.27% | | OCB (Orient Commercial Bank) | 25415 | 25940 | 2.04% | -4.43% | | VPBank (Vietnam Prosperity Bank) | 25545 | 25908 | 1.41% | -4.25% | | MSB (Vietnam Maritime Commercial Joint Stock Bank) | 25519 | 25899 | 1.48% | -4.31% | | Eximbank (Vietnam Export Import Commercial Joint Stock Bank) | 25520 | 25910 | 1.52% | -4.29% | | Sacombank (Saigon Thuong Tin Commercial Joint Stock Bank) | 25550 | 25910 | 1.40% | -4.24% | | MB (Military Commercial Joint Stock Bank) | 25505 | 25935 | 1.67% | -4.27% | | HSBC Vietnam | 25526 | 25833 | 1.20% | -4.42% | | **VietABank (Viet A Bank)** | 25512 | 25912 | 1.56% | -4.30% | | BaoViet Bank | 25535 | 25915 | 1.48% | -4.25% | | PVcomBank | 25460 | 25870 | 1.60% | -4.48% | | TPBank (Tien Phong Bank) | 25127 | 25910 | 3.07% | -5.02% | | Vietbank (Viet Nam Thuong Tin) | 25487 | 25866 | 1.48% | -4.43% | | Bac A Bank | 25530 | 25820 | 1.13% | -4.44% | | Hong Leong Bank Vietnam | 25510 | 25910 | 1.56% | -4.31% | | Standard Chartered Vietnam | 25490 | 25890 | 1.56% | -4.38% | | UOB Vietnam | 25400 | 25890 | 1.91% | -4.55% | | MBV (Modern Bank of Vietnam, formerly OceanBank) | 25484 | 26006 | 2.03% | -4.18% | | ICBC Hanoi Branch | 25490 | 25870 | 1.48% | -4.42% | | Vikki Bank (formerly DongA Bank) | 25550 | 25880 | 1.28% | -4.29% | | Woori Bank Vietnam | 25505 | 25930 | 1.65% | -4.28% | | MUFG Bank Ho Chi Minh City Branch | 25510 | 25830 | 1.25% | -4.46% | VietABank had the 16th narrowest USD spread of the 30.

The State Bank of Vietnam rate is the one tax, accounting and customs rules in Vietnam name; nobody transacts at it. VietABank's board is the price a customer actually gets. The API puts both on every row: `official` is the central bank's rate for the same currency and `vs_official_pct` is how far the bank's mid sits from it. Use the board to show customers a real price, compare banks for a remittance, or keep a dated record of what the bank quoted; use the [State Bank of Vietnam endpoint](https://allratestoday.com/central-bank-rates-api/sbv/) when a rule asks for the official rate. ## FAQ ### Where do the VietABank (Viet A Bank) rates come from? From the bank's own public rates page (https://www.vietabank.com.vn/tien-ich/ty-gia/ty-gia-ngoai-te.html), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price VietABank shows, with the mid, the spread and the State Bank of Vietnam rate added. ### Are these the official VND exchange rates? No. They are VietABank's retail prices for customers. The official rate in Vietnam is the State Bank of Vietnam rate, which the API returns as `official` on each row where the central bank has one, and in full from the central-bank endpoint. ### How often is the VietABank board updated? AllRatesToday reads the page every hour. The bank prints no timestamp, so `captured_at` tells you when the rates were read. ### Can I get VietABank rates for a past date? Yes, from 14 November 2026 onward; every day's board is kept permanently. Add `?date=YYYY-MM-DD` for one day: the response is the board captured that day, or the nearest earlier day within five days, with `date_requested` and `snapshot_date` added. For a range, `/history?ccy=USD&from=…&to=…` returns one row per day as JSON, CSV, XML or XLSX on paid plans. ### Do I need an API key? Yes. Commercial bank boards need an API key; any plan works, the free key included, and each call counts against the plan. Public pages or widgets that show the rates need a visible link to allratestoday.com. ## VietABank (Viet A Bank) rates, as JSON Free API key, hourly board captures, the official rate alongside.
