Where to Exchange Money in Thailand for the Best Rate — Exchange Booths vs Banks vs Airport vs ATMs, and Which Notes to Bring
Licensed exchange booths in Thai cities usually beat banks, airports and ATMs on rate. How to read a rate board, why the condition and size of your notes changes the rate, what to avoid at the airport, and how much cash to carry.
Thailand still runs on cash in markets, taxis, small restaurants and most of the countryside, so at some point you will exchange money. The rate you get varies far more than most visitors expect, and the difference between the best and worst option on the same street can be several percent. This guide explains where the good rates are and how to get them.
The options, ranked by rate
| Option | Rate quality | Notes |
|---|---|---|
| Licensed exchange booths in city centres | Best | Competitive chains in Bangkok, Chiang Mai, Phuket, Pattaya; rates posted on boards |
| Bank branches and bank exchange counters | Good | Slightly worse than the best booths, but everywhere and reliable |
| ATMs with a foreign card | Fair to poor | Bank rate is fine, but fixed fees and the conversion trap add up; see ATM fees |
| Airport counters in the arrivals hall | Poor | Convenient and noticeably worse; exchange only what you need for the first day |
| Hotels | Worst | For emergencies only |
Reading a rate board
Boards show a buying and a selling rate for each currency and often several rows for the same currency by note denomination. Large notes get the best rate; small notes and coins get a worse rate or are refused. Some booths also list a lower rate for older series of notes. The rate you care about is the booth's buying rate for your currency's largest notes.
Which notes to bring
Bring clean, unfolded, undamaged notes of the largest denominations in a major currency. Notes with tears, writing, stamps or heavy creases are refused or discounted at almost every booth. If your home currency is less common, changing to a major currency at home first may cost more than the difference here, so check the board for your currency before deciding.
How much cash to carry
Card acceptance is good in cities and tourist areas at hotels, malls, chain stores and larger restaurants, and QR payments are everywhere but require a Thai bank app. Cash is needed for markets, street food, taxis without apps, small guesthouses, boats and rural areas. A sensible pattern is to exchange enough for a few days at a time at a good booth rather than a large sum at the airport.
At the airport
The counters in the arrivals hall are convenient and their rates reflect it. If you need baht immediately, change a small amount there or withdraw a small amount from an ATM (declining conversion), then change the rest in the city. Some airports have better-rated booths on the lower or departure levels; it is worth a short walk.
Safety and receipts
Use booths in open, busy locations, count the money before leaving the counter, and keep the receipt. Never exchange with individuals who approach you, whatever rate they offer.
Common mistakes
- Changing a large amount at the arrivals counter. Change a little, then find a city booth.
- Bringing small or worn notes. They get a worse rate or are refused.
- Accepting home-currency conversion at ATMs and card terminals. Always pay in baht.
Summary
Bring large, clean notes of a major currency, change a small amount at the airport and the rest at a licensed city booth, and keep some cash for markets and transport while paying by card where it is accepted. If you stay long, a Thai bank account and QR payments replace most of this.
