Navigating Currency Exchange in Thailand: Banks vs. Kiosks

Most visitors heading to Thailand in 2026 walk off the plane at Suvarnabhumi or Don Mueang with one pressing question: where do I get Thai Baht without getting ripped off? The airport exchange counters are right there, brightly lit and impossible to miss — and they’re almost never the best option. Between airport kiosks charging inflated spreads, ATMs stacking fees, and merchants pushing dynamic currency conversion, it’s genuinely easy to lose hundreds of baht every single day without realising it. This guide cuts through the confusion and tells you exactly what works, what doesn’t, and what has changed in 2026.

Understanding the Thai Baht Before You Arrive

Thailand’s official currency is the Thai Baht (THB). Knowing the denominations before you land saves you from fumbling at a market stall or accidentally handing over a 1,000 THB note for a 40 THB bowl of noodles.

Banknotes come in five denominations: 20, 50, 100, 500, and 1,000 THB. The 1,000 THB note is dark brown and the most valuable. The 100 THB note (red) is your everyday workhorse. The 20 THB note (green) is useful for small street food purchases.

Coins are 1, 2, 5, and 10 THB. You’ll also occasionally receive 25 and 50 satang coins as change, though they’re rarely used in daily transactions and most vendors just round up.

One practical note: street vendors and tuk-tuk drivers rarely have change for 500 or 1,000 THB notes, especially early in the day. When you exchange money, always ask for a mix of 100 and 50 THB notes alongside any larger ones. That simple habit prevents a lot of awkward moments.

Banks vs. Dedicated Exchange Kiosks — Where to Actually Exchange

This is the core decision most travellers get wrong. The short answer: dedicated exchange kiosks nearly always beat banks on rate, sometimes significantly.

Major Thai Banks

Bangkok Bank (bangkokbank.com), Kasikornbank (kasikornbank.com), Siam Commercial Bank at scb.co.th, and Krungthai Bank (krungthai.com) all offer currency exchange. You’ll find branches at both Suvarnabhumi (BKK) and Don Mueang (DMK) airports, operating 24/7. Regular branches in cities operate roughly 09:00–15:30 on weekdays, with mall branches sometimes staying open until 16:30.

Banks do not charge a direct commission. Their margin is baked into the exchange rate spread — the gap between what they buy and sell a currency for. For major currencies like USD, EUR, or GBP, that spread tends to be wider than what you’d get at a dedicated kiosk. You’ll need your passport for every transaction.

Dedicated Exchange Kiosks

This is where you want to be. The most reputable names in Thailand are:

• Super Rich Thailand (superrichthailand.com) — consistently among the best rates in Bangkok, with branches near major BTS stations
• TT Currency Exchange (ttexchange.co.th) — strong presence in tourist zones and shopping malls
• Vasu Exchange (vasuexchange.com) — competitive for major currencies, good for less common ones

Kiosks operate from roughly 09:00–20:00 in tourist areas, and 24/7 at airports. Like banks, they charge no direct commission — the rate is where they profit. But because kiosks compete aggressively for volume, they consistently offer tighter spreads, meaning more baht in your pocket for the same foreign currency.

The step-by-step process at any kiosk: walk up, check the displayed rate board for your currency, hand over your foreign cash and passport, confirm the THB amount they quote, and count your money before walking away. Wait times run 5–10 minutes, slightly longer during peak hours at busy tourist spots.

Using ATMs in Thailand — Fees, Limits, and the DCC Trap

ATMs are everywhere in Thailand: inside banks, at every 7-Eleven and FamilyMart, in shopping malls, and near major tourist sites. Your international Visa, Mastercard, Plus, or Cirrus card will work at virtually all of them.

Here’s the cost reality: Thai banks charge a flat 220 THB fee per international card withdrawal, regardless of how much you take out. This fee is charged on top of whatever your home bank charges for foreign transactions. As of 2026, this 220 THB fee has remained stable and no change is anticipated.

Withdrawal limits are typically 10,000–30,000 THB per transaction. Some bank ATMs allow up to 50,000 THB. To minimise how often you pay that 220 THB fee, withdraw larger amounts less frequently rather than small amounts regularly.

The DCC trap is the biggest ATM mistake tourists make. When the screen asks whether you want to be charged in your home currency (USD, EUR, GBP, etc.) or in Thai Baht, always — without exception — choose Thai Baht. Dynamic Currency Conversion (DCC) means the ATM operator sets the exchange rate, and it is reliably worse than your card issuer’s rate. Choosing THB lets your home bank handle the conversion at a far better rate.

Step-by-step ATM process: insert your card, select English, enter your PIN, choose Withdrawal, select the account type (Savings or Credit depending on your card), enter the THB amount, confirm the 220 THB fee when shown, and when prompted on currency — choose THB. Collect cash, card, and receipt.

Digital Wallets and QR Payments — What Actually Works for Tourists

Thailand’s PromptPay QR system is now so widespread that even small market vendors and motorbike taxi drivers accept it. The blue-and-white QR stickers are genuinely everywhere. But here’s the honest reality for tourists in 2026: you cannot simply scan a Thai merchant’s PromptPay QR code from most foreign banking apps. Direct integration requires a Thai bank account, which requires a non-immigrant visa and proof of address — not something most tourists have.

Some international apps like Wise and Revolut are developing PromptPay send capabilities, and certain regional wallets (Alipay, WeChat Pay) have bilateral agreements, but direct merchant QR scanning from a foreign app is still not the standard experience in 2026. Monitor announcements from your own bank or payment app before departure.

TrueMoney Wallet

This is the most practical digital option for tourists. Download the TrueMoney Wallet app (truemoney.com) from the App Store or Google Play, register with your international mobile number, and verify with your passport. Top it up with cash at any 7-Eleven by telling the cashier you want to top up TrueMoney, or link an international Visa/Mastercard within the app. Once funded, you can scan PromptPay and TrueMoney QR codes at millions of merchants — 7-Eleven, FamilyMart, Lotus’s, Makro, and far beyond. It’s a genuine game-changer for convenience.

Rabbit LINE Pay

Rabbit LINE Pay (rabbitlinepay.com) is particularly useful in Bangkok. It’s integrated with the LINE messaging app and works at BTS Skytrain stations, McDonald’s, Starbucks, and a growing list of urban merchants. You can link an international credit or debit card to pay. If you’re spending significant time in Bangkok using the BTS, it’s worth setting up. Physical Rabbit cards for BTS are also still available at any station if you prefer keeping it simple.

Paying by International Credit or Debit Card

Visa and Mastercard work at major hotels, department stores, large supermarkets, and upscale restaurants. American Express and Discover are accepted far less commonly — don’t rely on them. Contactless tap-to-pay is increasingly available at larger establishments in 2026, and Apple Pay and Google Pay linked to international cards work at an expanding number of terminals.

Cash remains essential for anything smaller: local markets, street food, independent guesthouses, songthaews, tuk-tuks, and local buses are predominantly cash-only. Carry at least 500–1,000 THB in small notes at all times.

The same DCC warning applies at card terminals. If a merchant’s payment machine offers to charge you in your home currency, decline it and pay in THB. The rate you get through your card issuer will almost always be better. Your home bank may also charge a foreign transaction fee of 0–3% per purchase — check before you leave.

2026 Budget Reality — Cash Needs and Tipping

How much cash you actually need depends heavily on how you travel:

• Budget traveller (hostels, street food, local transport): 500–800 THB per day in cash, mostly for food and short trips
• Mid-range traveller (mid-tier hotels, mix of restaurants, occasional tours): 1,000–2,000 THB per day, with larger expenses handled by card
• Comfortable traveller (boutique hotels, restaurants, spas, shopping): 2,000–4,000+ THB per day, with cards covering the bulk of hotel and dining bills

Tipping is not mandatory in Thailand, but it is genuinely appreciated. Current 2026 norms:

• Restaurants: Many mid-range to upscale restaurants automatically add a 10% service charge. If not, 10% is appropriate for good service. At street food stalls, round up or leave small change.
• Massage: 50–100 THB for a standard one-hour massage is standard.
• Taxi or Grab: Round up the fare or add 20–50 THB for good service. Grab (grab.com) lets you tip in-app.
• Hotel staff: 20–50 THB for a bellhop or housekeeper is a fair gesture.

Always tip in cash directly to the person who served you. Money left on a table or added to a card bill does not always reach the individual.

Common Mistakes That Cost Tourists Money

• Exchanging everything at the airport: Rates at airport arrival hall counters — especially those run by small independent operators — are among the worst available. Exchange only what you need for immediate expenses, then use a Super Rich or TT Currency Exchange branch in the city.
• Accepting DCC at ATMs or card terminals: This is the single most common and most avoidable financial mistake in Thailand. Always pay and withdraw in THB.
• Withdrawing small amounts frequently: Every ATM withdrawal costs 220 THB regardless of the amount. Consolidate your withdrawals.
• Assuming cards work everywhere: Markets, street food, tuk-tuks, local buses, and many guesthouses are cash-only. Running out of baht at 11pm at a night market is a real situation.
• Bringing worn or damaged foreign notes: Exchange kiosks may refuse or offer lower rates for notes that are torn, heavily marked, or old series. Bring clean, current-series banknotes from home.
• Forgetting your passport: You cannot exchange currency at any bank or kiosk in Thailand without a valid passport. A photo on your phone is not accepted.

Frequently Asked Questions

What is the best place to exchange currency in Thailand?

Dedicated exchange kiosks like Super Rich Thailand (superrichthailand.com) and TT Currency Exchange (ttexchange.co.th) consistently offer better rates than banks or airport counters. Exchange a small amount at the airport for immediate needs, then find a kiosk in the city for the bulk of your money. Always bring your passport.

How much does an ATM withdrawal cost in Thailand in 2026?

Thai banks charge a flat 220 THB fee per international card withdrawal. This applies regardless of how much you withdraw, and it’s charged on top of any fees from your home bank. To reduce the impact, withdraw larger amounts less frequently. Always choose to be charged in Thai Baht, not your home currency, when the ATM prompts you.

Can tourists use PromptPay QR codes in Thailand?

Not directly from most foreign banking apps. PromptPay requires a Thai bank account for merchant QR payments. Tourists can access PromptPay payments indirectly through TrueMoney Wallet, which tourists can register and top up using a passport and international mobile number. Some regional apps like Alipay have limited bilateral integrations in 2026.

Is cash still necessary in Thailand in 2026?

Yes, absolutely. Street food stalls, local markets, tuk-tuks, songthaews, and many smaller guesthouses are cash-only. Digital payments are growing fast in cities, but once you step away from major tourist zones or into any local market, cash is essential. Always carry at least 500–1,000 THB in smaller notes.

Should I tip in Thailand, and how much?

Tipping is not mandatory but is genuinely appreciated. Standard amounts in 2026: 50–100 THB for a one-hour massage, 20–50 THB for taxi or hotel staff, and 10% at restaurants if a service charge isn’t already included. Always tip in cash directly to the person who served you rather than leaving it on the table.
