Thai Bank Exchange Rates
The Bank of Thailand rate, Bangkok Bank and the major Thai banks, and how they all compare with the mid-market rate you see on a converter.
Quick answer
The Bank of Thailand publishes a daily reference rate for the baht. It is a benchmark, not a rate anyone can transact at. Thai retail banks such as Bangkok Bank, Kasikorn and SCB quote their own buy and sell rates around it, and the gap between those rates and the mid-market figure is the real cost of using the bank. The mid-market rate on a converter sits very close to the BOT reference, and a specialist transfer service usually prices nearer to it than a retail bank counter does.

What the Bank of Thailand rate actually is
Each business day the Bank of Thailand publishes a reference exchange rate for the baht against the major currencies. It is the cleanest public benchmark for what the baht is worth. Businesses use it for accounting, the press quotes it, and other rates orbit around it. But a retail customer cannot walk into a bank and transact at the BOT rate. It is a reference point, not a dealing price.
The mid-market rate shown on a converter does the same job for consumers. It is the midpoint between the buy and sell prices on the global market, with no bank margin included. That makes it the right yardstick for comparing any quote you are offered, from a Thai bank or anyone else.
How Bangkok Bank and the Thai banks set their rates
Thai retail banks quote two rates every day for each currency: a buy rate (what they pay when you sell them foreign currency) and a sell rate (what they charge when you buy). The difference between the two is the spread, and the spread is the bank's margin on the exchange. The major banks active in retail FX are:
- Bangkok Bank (BBL) — the largest, with the widest branch network for receiving transfers.
- Kasikornbank (KBank) and Siam Commercial Bank (SCB) — large retail banks with strong digital apps.
- Krungsri (Bank of Ayudhya) and TMB Thanachart — also competitive on retail rates.
Each bank sets its own spread, and the spread can vary by amount, by branch and by whether the deal is a cash exchange, a transfer or a card payment. A Bangkok Bank branch and a Kasikorn branch on the same street can quote different baht for the same dollar on the same morning.
Thai bank rate versus the mid-market rate
The mid-market rate is the neutral baseline. A Thai bank's rate sits below it when you buy foreign currency and above it when you sell, and the bank keeps the gap. On a small exchange that gap looks tiny. On a property deposit, a retirement lump sum or a monthly pension transfer, it runs into serious money. A two percent spread on THB 800,000 is THB 16,000 before any fee.
That is why the work is always the same: take the mid-market figure for your currency, then compare every quote against it. The Baht rates page gives the mid-market reference for GBP, USD, EUR and SGD, and the provider leaderboard shows which transfer services price closest to it.
Cash, bank or money changer?
For physical cash in Thailand, licensed money changers such as SuperRich and Vasu often beat the bank counters, especially on US dollars and Singapore dollars. Airport booths give the worst rates of all and should be a last resort. For anything large, a specialist transfer service sent to a Thai bank account usually beats both the cash counter and the retail bank counter, because it prices close to mid-market and shows the fee separately.
If you hold a foreign currency and need baht, start with the GBP to THB, SGD to THB or USD to THB converter to get the clean figure, then compare a provider quote against it.

Thai bank exchange rates: your questions
What is the Bank of Thailand exchange rate?
The Bank of Thailand publishes a daily reference exchange rate for the baht against major currencies. It is a benchmark used by banks, businesses and the press, not a rate you can transact at. Thai banks build their own buy and sell rates around it, and add a spread. The mid-market rate you see on converter sites sits very close to the BOT reference.
Is the Bangkok Bank rate the same as the Bank of Thailand rate?
No. Bangkok Bank, like every Thai retail bank, quotes its own buy and sell rates each day. These sit around the Bank of Thailand reference rate but include the bank's margin. The gap between the bank's rate and the mid-market rate is the real cost of using that bank, on top of any fee.
Do Thai banks use the mid-market rate?
No bank gives retail customers the pure mid-market rate. Thai banks quote a buy rate and a sell rate, and the difference between them, the spread, is how they make money on the exchange. Specialist transfer services usually price closer to mid-market than retail banks do.
Where can I check live Thai bank exchange rates?
For the official benchmark, use the Bank of Thailand website. For retail rates, check the bank's own daily rate page. Bangkok Bank, Kasikorn (KBank), SCB and Krungsri all publish daily rates. Always compare the rate you are offered against the mid-market reference before you agree.
Bank or money changer for cash in Thailand?
For cash, licensed money changers such as SuperRich and Vasu often offer rates closer to mid-market than the banks, especially on the greenback and the Singapore dollar. Airport booths give the worst rates. For large transfers, a specialist service sent to a Thai bank account usually beats both cash and the retail counter.
