I. Audit Notes

  • Data Currency: Information current as of April 5, 2026
  • System Maturity: BAHTNET is mature (operational since 1994, modernized 2008, ISO 20022 migration planned 2026–2028). PromptPay is mature at national scale (launched July 2016, 79 million IDs by May 2024). Thai QR standard established; merchant adoption expanding (7.4+ million acceptance points). Traditional ITMX clearing system sees gradual volume migration to PromptPay for instant use cases.
  • Market Dominance: E-wallet market dominated by TrueMoney (53%) and Rabbit LINE Pay (25%); duopoly structure reflects high market concentration. Card networks dominated by Visa and Mastercard internationally. PromptPay is de facto instant payment standard.
  • Regulatory Oversight: Bank of Thailand maintains clear supervisory authority over all payment systems via Payment System Committee and Payment Systems Supervision Department. National ITMX operates under BOT direction. All e-wallets and payment service providers licensed and regulated by BOT.
  • Cross-border Innovation: PromptPay-PayNow linkage (Singapore) operational and successful; demonstrates Thailand's innovation in cross-border payments. BOT actively exploring similar linkages with Malaysia and India.
  • Future Roadmap: Digital Baht (CBDC) in research phase; BAHTNET ISO 20022 migration planned; potential extended operating hours for BAHTNET; continued merchant adoption of Thai QR standard.
  • Emerging Risks: E-wallet duopoly concentration may limit competition; market dominance of TrueMoney could create systemic risk if operational disruption occurs; regulatory framework for emerging fintechs (BNPL, embedded finance) still evolving.
