Latest board, read 16 Nov 2026, 01:22 Thailand time (0h ago)

Bank’s own last-updated stamp: 2026-11-13 16:05 (round 2) (as printed on its page, local time).

Board shown: SWIFT/telex buy / draft & SWIFT 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 Thailand 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 Bank of Thailand 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.

A range for one currency, one row per day, paid plans: /api/v1/bank-rates/th/gsb/history with ccy, from and to (default: the last year). Billed one call per month covered.
