Quick Answer
Opening a Krungsri (Bank of Ayudhya) Account as a Foreigner
Krungsri is MUFG-owned with polished English service — a strong choice for Japanese and Western expats.
Krungsri, formally the Bank of Ayudhya, is Thailand's fifth-largest commercial bank and a member of the Japanese MUFG group. Its majority Japanese ownership shows up in the customer experience: branches in business districts are unusually organised, staff at flagship locations speak strong English (and Japanese), and the KMA — Krungsri Mobile App — is clean and reliable. This guide is for foreigners on a long-stay visa considering Krungsri as either a primary or secondary Thai bank, and it covers visa eligibility, documents, recommended branches, mobile banking setup, and the day-to-day fees you can expect.
Why Choose Krungsri
Krungsri is the de facto bank of choice for the large Japanese expatriate community in Thailand, and that focus has spilled over into general foreign service standards. Branches inside business districts and Japanese-heavy areas like Asok, Phrom Phong, Thonglor, and Sri Racha tend to have English- and Japanese-speaking staff and bilingual paperwork. MUFG ownership also means strong correspondent relationships with Japanese banks (Mitsubishi UFJ, MUFG New York) and competitive treatment of inbound JPY and USD wires. For freelancers and digital nomads, Krungsri's interest rates on standard savings accounts are competitive, and the KMA app is fast at executing PromptPay transfers and QR scans.
Visa Types and Required Documents
Krungsri accepts Non-Immigrant B, O, ED, LTR, Smart Visa, and Thailand Privilege holders for standard savings accounts. You will need your original passport with the current visa stamp, a copy of the photo page and visa page, and proof of address — typically a TM30 receipt, signed rental contract, or Certificate of Residence from Thai Immigration. A Thai mobile number registered in your own name is required for KMA and PromptPay. The standard opening deposit is 500 THB. The debit card (commonly the Krungsri Debit Card or Krungsri Manee Mungkung gold card) has an issuance fee around 300 THB and an annual fee around 300 to 599 THB depending on tier. Work-permit holders should also bring the original work permit, as it materially accelerates the application.
Recommended Branches
For foreigners, the Krungsri branches in Ploenchit Tower, Park Ventures Ecoplex, EmQuartier, Asoke (Sukhumvit 21), Phrom Phong (Sukhumvit 39), and Thonglor (Sukhumvit 55) are the easiest options in Bangkok — they have polished English service and consistent procedures. The Sri Racha branch is the flagship for Eastern Seaboard Japanese expats. Outside Bangkok, Pattaya (Central Festival), Phuket Town, Chiang Mai (Nimmanhaemin and Promenada), Hua Hin, and Khon Kaen have foreigner-experienced branches. Small upcountry branches may refuse new foreign customers or insist on documents in a particular order — use a flagship branch for the first opening, then transfer your home branch later if you wish.
Activating KMA Mobile Banking
KMA is Krungsri's mobile app and supports transfers, QR PromptPay, bill payment, mutual funds (via Krungsri Asset Management), gold trading, and digital savings accounts. It is available in Thai and English and is regarded as one of the snappier Thai banking apps. Activation must happen at the branch with biometric face-scan verification under Bank of Thailand's KYC rules. Default daily transfer limits inside KMA are typically 200,000 THB and can be raised in-app to 2 million THB or more. Push notifications are reliable and can be filtered per account. For high-value transactions, KMA supports two-factor confirmation via fingerprint or face ID on the registered handset.
PromptPay, QR, and Daily Use
PromptPay registration is straightforward at branch or in KMA after activation, linking either to your Thai mobile number or your tax ID. As with every Thai bank, transfers under 5,000 THB are free, and QR payments at merchants — including the bank's own Krungsri merchant QR — settle through the national PromptPay rail in seconds. Krungsri ATMs are plentiful in Bangkok and tourist destinations, and the bank participates in the standard interbank ATM network. Out-of-network domestic withdrawals cost 10 to 20 THB. International withdrawals from foreign cards at Krungsri ATMs incur the standard 220 THB acquirer fee plus the home-bank's own charges.
Fees and Notable Costs
Krungsri's standard savings accounts are fee-free above a small minimum balance (commonly 2,000 THB). The debit card carries an annual fee of around 300 to 599 THB depending on tier. PromptPay transfers under 5,000 THB are free, and KMA in-app interbank transfers are also free. SMS alerts cost around 50 THB per quarter and are worth enabling. Foreign-currency conversion at Krungsri tends to use mid-tier FX spreads — slightly worse than Bangkok Bank for USD but competitive on JPY thanks to MUFG. For inbound wires, expect a lifting fee around 500 THB and prompt issuance of an FET form on request if the amount is over 50,000 USD.
