Opening a Thai Bank Account: Foreign-Entity and Individual Mechanics
Thai-bank-account opening mechanics for foreign entities and individuals are structurally complex and have tightened materially since 2023-2024 under enhanced AMLO, FATCA (US persons), and CRS (Common Reporting Standard) compliance requirements. Corporate-entity account opening: requires Thai-incorporated entity with valid Affidavit of Company Affairs from Department of Business Development (DBD); BOI-promoted, IBC-registered, or Treaty-of-Amity-registered entities preferred by Thai banks; work-permit-holding signatory typical, foreign signatories possible with documentation. Required documentation: Affidavit of Company Affairs (3-month validity), Memorandum of Association, list of shareholders, Board resolution authorising account opening and signatories, signatories' passports plus work permits, tax-identification number. Major foreign-friendly Thai banks: Bangkok Bank (most-foreign-friendly historically), Kasikorn Bank (KBank), SCB, Krungsri (BAY), UOB Thailand, Standard Chartered Thailand. Individual non-resident account opening: work-permit, valid Thai visa (long-term, ideally LTR / Smart Visa / non-immigrant B / Thailand Privilege), tax-identification number, Thai-resident-address-proof (utility bill, rental contract). Recent 2023-2025 tightening: banks require LTR / Smart Visa / equivalent strong-status visa; tourist-visa account-opening rejected. Digital-banking app onboarding (SCB Easy, K+, Bualuang) requires Thai-mobile-number tied to Thai national-ID or foreign-passport with appropriate visa. CRS reporting applies to non-resident accounts. Watch ongoing AMLO documentation-tightening and any LTR-account-streamlining preference.

Virtual Bank Licensing: BOT Framework and 2026 Launch
The Bank of Thailand awarded three virtual-bank licences on 19 June 2025 from a five-applicant pool: SCBX consortium (with WeBank and KakaoBank), Krungthai Bank consortium (with AIS and PTT OR), and ACM Holding (Charoen Pokphand Group's Ascend Money and TrueMoney). The framework derives from the BOT Ministerial Notification of 4 March 2024. Capital floor is THB 5B paid-up on day one, scaling to THB 10B within five years. Operations are digital-only β no branches, ATMs, or cash-deposit machines, with cash services provided through partnerships with post offices, convenience stores, and gas stations. Each consortium must begin operations within one year of the Minister of Finance's 19 June 2025 approval, putting the launch window squarely in mid-2026. Thailand becomes the third ASEAN country to license virtual banks after Singapore and Malaysia. Runner-up consortia in the five-applicant pool included Gulf Energy / Binance and SeaMoney / Sea Group.
