Thailand Currency Exchange Guide 2026 — Best Rates and Worst Traps

The Golden Rule of Thai Currency Exchange

Exchange rates in Thailand vary by up to 10% depending on where you change money. Airport exchanges offer the worst rates. Tourist area exchanges are slightly better. And dedicated exchange shops like SuperRich offer rates close to the mid-market rate. The difference on a $1,000 exchange can be $50-100 — enough to pay for several nights' accommodation.

Best Places to Exchange

SuperRich (green and orange): Thailand's best exchange rates, consistently within 0.5% of mid-market. Multiple branches in Bangkok (BTS-accessible), Chiang Mai, and Phuket. The green and orange SuperRich are different companies — compare both. Vasu Exchange, K79, Twelve Victory: Other exchange shops in Bangkok with competitive rates, especially for GBP and EUR. Downtown bank branches: Decent rates, trustworthy, and available everywhere. Not the best, but reliable. Airport exchanges: Dead last. Use them only if you need taxi fare to the city — exchange the minimum and find SuperRich later.

ATMs — The Hidden Cost

Thai ATMs charge a flat 220 THB fee per withdrawal, regardless of amount. Your home bank may add another 1-3% foreign transaction fee. That means withdrawing 5,000 THB (about $155) costs you $7+ in fees — a 4.5% effective exchange rate markup. If using ATMs, withdraw the maximum allowed (usually 20,000-30,000 THB) to minimise the per-transaction fee impact.

Traps to Avoid

"Dynamic Currency Conversion": When a Thai ATM or card terminal offers to charge you in your home currency instead of THB — ALWAYS decline. Choose THB. The "convenience" conversion rate is 3-5% worse. Hotel front desk exchanges: Convenient but 3-5% below market rates. Street money changers outside exchange shops: Risk of counterfeit bills and scam rates.

FAQ

Should I bring cash or use cards in Thailand?

Bring some cash (USD, EUR, GBP, or AUD) and exchange at SuperRich for the best rates. Use a no-foreign-fee debit card (Wise, Revolut) for ATM withdrawals as backup. Credit cards are accepted at hotels and upscale restaurants but not at local shops or markets.

Can I use USD directly in Thailand?

Almost never. Thailand runs on Thai baht. Some tourist shops may accept USD but at terrible exchange rates. Always pay in THB.

What denominations should I exchange into?

Get a mix of 100, 500, and 1,000 THB notes. Many small vendors and tuk-tuks can't break a 1,000 THB note. Coins aren't commonly used except for vending machines and small items.
