Thailand Currency & Money Guide: Exchange, Cards, and Tips

Thailand remains a cash-heavy economy where the Thai Baht (THB) is the sole legal tender. While credit cards and QR payments are widely accepted in major cities like Bangkok and Chiang Mai, you will need physical cash for street food, local markets, and island hopping. To minimize fees, use local exchange booths like SuperRich and withdraw large amounts from ATMs at once to offset the standard 220 THB foreign card fee.

The Thai Baht (THB) is the official currency, and as of early 2026, the exchange rate typically sits around 1 SGD to 26.50 THB, though this fluctuates with global market conditions. Banknotes come in denominations of 20 (green), 50 (blue), 100 (red), 500 (purple), and 1,000 (brown) Baht. It is important to treat Thai currency with respect, as all notes bear the image of the King; stepping on a coin or defacing a note is considered a serious legal and cultural offense.

For the best Thailand exchange rate, avoid the currency desks inside the arrival halls of Suvarnabhumi Airport, which often offer rates 5-10% lower than the city center. Instead, look for SuperRich (either the Green or Orange branches) or Vasu Exchange in Bangkok. These independent booths consistently offer better rates than commercial banks. According to data from the Tourism Authority of Thailand, the country saw a significant surge in visitors in 2024, leading to more competitive exchange services in tourist hubs like Phuket and Pattaya.

Managing multiple currencies can be a headache, but the Hello app simplifies this by tracking your expenses in real-time. Whether you are spending in THB or SGD, the app’s multi-currency tracker uses automatic exchange rate conversion to show you exactly how much you are spending against your home budget. This is particularly helpful when you are trying to stick to a daily limit while navigating the bustling markets of Thailand.

Most Thai ATMs charge a flat fee of 220 THB (approximately $8.50 SGD) per withdrawal for foreign cards, making large, infrequent withdrawals the most cost-effective strategy for travelers. To avoid unnecessary costs, always choose 'Continue Without Conversion' when the ATM asks if you want to use their exchange rate; your home bank will almost always provide a better rate. Credit cards like Visa and Mastercard are standard in shopping malls, high-end restaurants, and major hotels, but many smaller establishments still enforce a 3% surcharge for card payments.

For seamless navigation and to use local digital payment apps, staying connected is essential. An eSIM from Hello ensures you have instant data upon landing, allowing you to check live exchange rates or use banking apps securely. Hello's eSIM plans are designed for travelers who need reliable connectivity without the hassle of hunting for a physical SIM card at the airport.

Tipping in Thailand is not mandatory or traditionally part of the culture, but it is increasingly expected and appreciated in tourist-heavy areas as a gesture of thanks for good service. In high-end restaurants, a 10% service charge is often already included in the bill, so check for a 'plus plus' (++) sign next to prices, which indicates service and VAT are not yet added. If no service charge is present, leaving a 10% tip is a generous standard for a sit-down meal.

For smaller services, the rules are more relaxed. For a traditional Thai massage, a tip of 50 to 100 THB is standard and should be given directly to the therapist. When taking a taxi, most locals simply round up the fare to the nearest 10 or 20 Baht. For example, if a fare is 82 Baht, giving 100 Baht and telling the driver to keep the change is a common practice. In 2026, as the cost of living rises, these small tips make a meaningful difference to service workers who often rely on them to supplement their base wages. If you are traveling with a group, the Hello app’s expense splitting feature is perfect for managing these shared costs, allowing you to split restaurant bills and tips fairly in any currency.

Travelers can save money and avoid frustration by being aware of common tourist traps, such as the infamous 'Grand Palace is closed' scam where tuk-tuk drivers redirect you to expensive gem shops. Always insist on using the meter in taxis, or better yet, use ride-hailing apps like Grab or Bolt, which offer transparent, upfront pricing. According to the Ministry of Tourism and Sports, Thailand welcomed over 28 million international tourists in 2023, and with numbers rising, price transparency in transport has become a major focus for local authorities.

To save on food, head to 'Food Courts' in malls like Terminal 21, where you can find authentic street-style meals for 50-80 THB in a clean, air-conditioned environment. Street food remains the ultimate budget hack, with a bowl of boat noodles or a plate of Pad Thai typically costing between 40 and 70 THB in 2026. Another great Thailand money tip is to buy your water and snacks at 7-Eleven rather than at tourist sites, where prices can be marked up by 200%. To keep your budget on track, use the Hello app’s AI receipt scanning. You can simply snap a photo of your 7-Eleven or restaurant receipt, and the app will automatically categorize the expense and convert the currency for you.

Navigating Thai finances often involves questions about daily budgets, ATM limits, and the best way to pay for local experiences. Many travelers wonder how much cash to carry daily; for a comfortable mid-range experience, 1,500 to 2,500 THB per person is usually sufficient for food, transport, and minor activities.

Can I use Singapore Dollars (SGD) in Thailand? No, SGD is not accepted for transactions. You must exchange your SGD for Thai Baht at a bank or currency exchange booth. However, most exchange booths in major cities will happily accept SGD notes for conversion.

Are ATMs in Thailand safe? Yes, ATMs are generally very safe. To minimize the risk of skimming, use machines located inside bank branches or major shopping malls rather than isolated ones on the street.

Do I need a local bank account for QR payments? While the local PromptPay system is ubiquitous, it usually requires a Thai bank account. However, some international banking apps and digital wallets are starting to support cross-border QR payments. To stay updated and manage your spending, ensure you have a Hello eSIM so you can access your banking apps and the Hello app's budget tracking features wherever you are. Using Hello's voice expense entry is a quick way to log your cash spending on the go without stopping to type.
