Fintech & digital payments rules in Thailand (2026)

The Bank of Thailand expanded its Enhanced Regulatory Sandbox on 24 December 2025 to allow DLT-based programmable payments and Thai-baht-pegged stablecoins, accepting open-ended applications. This is the first supervised pathway for condition-based smart-contract payments in Thailand and feeds directly into the CBDC learnings from 2023.

On the BOT's recommendation, the Minister of Finance approved three consortia — Krung Thai Bank/AIS/PTT-OR, SCBX/WeBank/KakaoBank, and a third group — to establish fully digital banks targeting the underserved, each requiring THB 5 billion initial capital rising to THB 10 billion within five years. Operations must begin within one year of approval.

Amendments to the Emergency Decree B.E. 2561 (2018) require offshore digital asset platforms that actively target Thai users to obtain Ministry of Finance approval before offering services in Thailand. The amendment closes a key regulatory gap exploited by unlicensed cross-border crypto operators.

The SEC revised Notification No. 5/2565, granting digital asset operators enrolled in the BOT's Programmable Payment sandbox a specific exemption from the blanket crypto-as-payment ban. This allows live testing of tokenised baht payments while keeping the general prohibition in force.

Following a live pilot from late 2022 to October 2023 with ~4,000 users and 140 merchants across three financial service providers, the BOT concluded that a retail digital baht could foster competition and support programmable payments but announced no immediate plans for full-scale issuance.

At the G20 Bali Summit, the central banks of Indonesia, Malaysia, the Philippines, Singapore, and Thailand signed an MOU committing to interconnect their national fast-payment systems. The agreement formalised the ASEAN Payment Connectivity initiative and extended PromptPay's bilateral linkages into a regional network.

Thailand's PDPA — enacted in 2019 but enforcement-deferred — became fully operative in June 2022, imposing GDPR-style consent, breach-notification, and data-minimisation obligations with fines up to THB 5 million. It directly affects fintech KYC flows, biometric onboarding, and payment-data sharing between providers.

The Thai SEC issued Notification No. 5/2565 prohibiting licensed digital asset exchanges, brokers, and custodians from facilitating or promoting cryptocurrency as payment for goods and services, citing volatility, money-laundering risk, and threats to monetary stability. Crypto trading on licensed exchanges was unaffected.

The landmark Act replaced Thailand's fragmented payment laws, giving the Bank of Thailand statutory authority over essential payment infrastructure, supervised payment networks, and designated payment services (e-money, card schemes, bill payment, electronic funds transfer). It introduced payment-finality protections, customer-fund safeguards, and oversight aligned with CPMI-IOSCO Principles for Financial Market Infrastructures.

The BOT-mandated PromptPay system — operated by National ITMX and built on alias-based routing (mobile number or national ID) — went live in January 2017 as the centrepiece of the National e-Payment Master Plan. It enabled near-zero-fee real-time interbank transfers and grew to 67 million registered users by 2023, later adding QR merchant payments and government disbursements.

The BOT published its sandbox framework in December 2016, offering financial institutions and fintech companies supervised 6–12 month testing windows for innovations under BOT oversight. Early sandbox work produced the Thai QR Code Payment Standard, subsequently adopted as the national QR standard by all banks.

The Ministry of Finance and BOT jointly launched a five-pillar national digital payments strategy — covering PromptPay, card-terminal expansion, e-tax, government e-disbursements, and public education — targeting annual savings of THB 75 billion from reduced cash usage. It set the strategic foundation for Thailand's entire digital payments ecosystem over the following decade.
