BANGKOK, THAILAND – Thailand’s major banks tightened account opening rules for foreigners even as they expanded digital payment services and mobile banking across the country.
Local accounts now essential for long-stay visitors
For people who spent several months or lived permanently in Thailand, a local bank account was described as almost indispensable, simplifying rent payments and utility bills and reducing reliance on cash. The country developed into one of the region’s most advanced markets for digital payments, making everyday use of cash less important.
The banking landscape differed markedly from Europe, with five large institutions dominating the market, each with its own culture and strengths. Knowing these differences helped long-term guests choose the bank that best matched their needs.
Major banks position for different customer needs
The Bangkok Bank was the country’s largest lender by total assets and maintained branches in London, New York and several Asian cities, making it attractive for international transfers. Its branch service was polite but very formal, with staff insisting on correctly completed forms and accepting longer processing times in return for perceived stability.
The Kasikornbank stood out for its bright green branding and strong reputation among younger customers, offering modern, friendly branches. Its K PLUS mobile app provided reliable and clearly structured functions, allowing users to photograph and pay bills, top up mobile credit and make international transfers with a few clicks.
Digital drive at SCB and state-backed Krungthai
The Siam Commercial Bank (SCB), founded in 1907 and closely linked to the monarchy, presented itself as a technology company with a banking licence. Its elegant branches, especially investment centres in major shopping malls, targeted wealthier clients with special services and shorter waiting times, while the SCB Easy app integrated services such as food orders and travel bookings.
The state-majority-owned Krungthai Bank played a central role in handling public-sector salaries, pensions and support programmes and operated branches even in remote parts of the country. Its extensive network benefited those who travelled outside major cities, although some branches still felt bureaucratic and had long waits, and its app was functional rather than cutting-edge.
Foreign influence and low-fee challenger
Operating under the brand name Krungsri, the Bank of Ayudhya, majority-owned by Japan’s MUFG Group, was noted for exceptionally polite service and precisely organised processes. It built a strong position in car loans and consumer finance, with tidy, functional branches and a solid app aligned with international standards.
The merged TMBThanachart Bank (ttb) positioned itself as a fresher alternative to traditional giants, with a focus on transparent products and customers’ financial health. Its “All Free” account models removed many fees entirely, appealing to cost-conscious clients seeking clear structures without hidden charges.
Stricter account opening rules since 2025
Opening a bank account in Thailand became significantly more restrictive from 2025. A simple tourist visa no longer sufficed; applicants needed a longer-term status such as a Non-Immigrant visa, a retirement visa or a work permit at all major banks.
In addition to a valid passport and visa, most institutions required proof of residence in Thailand, such as an immigration registration certificate or a rental contract in the applicant’s name. Exact requirements could vary slightly between branches, making it advisable to come well prepared and, if necessary, try another branch.
PromptPay reduces need for cash
The key innovation in Thailand’s payment system was PromptPay, which enabled free real-time transfers between all Thai banks. Users needed only a mobile phone number or a QR code, making cash increasingly unnecessary in everyday life.
From street stalls to shopping malls, QR code stands appeared almost everywhere, allowing customers to scan, enter the amount and complete payment within seconds. Sellers received the money almost instantly in their account, and anyone with a Thai bank account was urged to activate PromptPay to make daily routines much easier.
Fees for ATMs and cards under scrutiny
While many digital services in Thailand were free, some charges remained significant, especially for foreign visitors. Using foreign bank cards at Thai ATMs cost a flat 220–250 baht per withdrawal, regardless of the amount taken out.
Thai debit cards usually carried annual fees of 100–500 baht, with some products including insurance services that pushed up prices. Customers were encouraged to ask for simpler, cheaper cards and to watch for charges when using other banks’ ATMs, though many institutions offered monthly free withdrawal quotas.
Cheaper international transfers and FX options
People who regularly sent money from Europe to Thailand were advised not to use their home bank, where fees were often high and exchange rates unfavourable. Specialised providers such as Wise generally offered better conditions and transferred funds directly into Thai accounts.
The euro–baht exchange rate fluctuated and at the time lay at around 35 to 37 baht per euro, prompting recommendations to monitor the rate for several weeks before moving large sums. Some Thai banks also offered foreign currency accounts, allowing customers to hold euros and convert into baht when the rate was more favourable.
Security standards raised for online banking
Thai banks invested heavily in digital security, increasingly requiring facial recognition via app for larger transfers to prevent abuse. Nevertheless, customers were warned about fraud attempts via fake SMS or emails designed to capture login data.
Users were urged to activate push notifications in their banking apps to be alerted immediately to any account movement and to react quickly to unauthorised debits. They were also told not to click on links in suspicious messages and to enter credentials only in official apps, as high institutional standards still relied on individual vigilance.
Apps make branches the exception
Mobile banking apps became so powerful that branch visits turned into rare events for many customers. Almost all transactions, from transfers and bill payments to standing orders and account statement downloads, could be handled via smartphone, with most apps offering an English-language version.
The apps of Kasikornbank (K PLUS) and SCB (SCB Easy) were highlighted as particularly user-friendly and reliable, while other large banks also provided robust solutions. Many older users reportedly found digital banking easier than expected once they explored the full range of functions.
Choosing the right bank for long-term stays
The choice of institution depended on personal priorities, with Bangkok Bank recommended for maximum security and international links. Those prioritising modern digital tools were steered towards Kasikornbank or SCB, while frequent visitors to rural regions benefited from Krungthai’s wide coverage.
Customers who valued especially friendly service were pointed to Krungsri, and fee-sensitive users were advised to look closely at ttb. Many long-stay guests ultimately held accounts with at least two banks in order to combine different advantages after visiting branches and speaking directly with staff.
Everyday precautions and future outlook
Customers were reminded never to share their PIN, to monitor account activity via app and to use ATMs only in well-lit, secure locations, preferably inside bank branches or shopping centres. Important documents, including passports and banking papers, were to be stored safely, with card-blocking hotlines kept separately or accessed through in-app block functions.
Thailand was described as rapidly becoming one of Asia’s leading markets for digital banking, increasingly using artificial intelligence to personalise offers and speed up loan approvals while maintaining an emphasis on personal relationships. The most successful institutions were expected to be those that combined digital efficiency with human warmth, even as conditions, fees and account-opening requirements remained subject to change and needed to be checked directly with each bank.
