The latest enforcement campaign follows a growing number of complaints from consumers regarding illegal online brokerage applications and aggressive social media promotions encouraging speculative currency trading with promises of unrealistic profits. According to the BOT, many of these operators disguise illicit investment schemes as legitimate merchant transactions, making payment gateways a critical point of enforcement. Authorities believe the abuse of digital payment systems has become increasingly sophisticated, requiring stricter oversight of payment infrastructure and stronger cooperation between financial institutions and law enforcement agencies.
Payment Gateways Face Greater Accountability
The central bank has made it clear that payment gateway operators will now shoulder greater responsibility for identifying suspicious merchants and preventing illegal financial activities. Under Thailand’s Payment Systems Act, operators are required to carry out rigorous Know Your Merchant (KYM) procedures before onboarding businesses and must continuously monitor transaction patterns for signs of unlawful activity.
Failure to comply could result in significant penalties, including administrative sanctions, suspension of payment services and recommendations to the Ministry of Finance to revoke an operator’s licence. The BOT warned that payment providers can no longer rely solely on automated verification systems and must actively investigate merchants whose transactions display unusual characteristics or appear linked to unlicensed FOREX businesses.
Regulators believe stronger compliance standards will significantly reduce the ability of underground financial operators to exploit legitimate payment infrastructure for illegal currency speculation and cross-border fund transfers.
Criminal Penalties for Illegal FOREX Activities
The BOT reiterated that operating an unlicensed FOREX business or facilitating domestic and international payment remittances connected to such operations violates Thailand’s Exchange Control Act of 1942. Individuals and businesses found guilty face prison terms of up to three years, fines reaching 20,000 baht or both.
Authorities also warned that promoting, advertising or soliciting investments in illegal currency trading schemes could trigger prosecution under the Emergency Decree on Loans Amounting to Cheating and Fraud. Convictions under that legislation carry far harsher penalties, including prison sentences ranging from five to ten years, fines of up to one million baht and additional daily penalties for continuing violations.
The BOT said these laws are designed to protect consumers from fraudulent investment schemes while safeguarding Thailand’s financial stability against speculative capital movements.
Digital Wallet Misuse Raises New Concerns
The regulatory campaign has expanded beyond traditional payment gateways to include foreign digital wallet platforms that have become increasingly popular among tourists and businesses.
Following the successful launch of the Thailand-China cross-border QR payment linkage in October 2025, authorities have identified growing misuse of peer-to-peer payment functions that enable unofficial cross-border fund transfers outside regulated banking channels. While the payment linkage was introduced to improve convenience for tourism and retail spending, regulators say some individuals have exploited personal QR payment systems to move money outside official exchange controls.
The BOT emphasized that all domestic commercial transactions conducted through foreign digital wallet platforms must be settled exclusively in Thai baht. Authorities are particularly concerned about peer-to-peer transfers conducted through overseas payment networks that bypass Thailand’s regulated banking infrastructure.
Cooperation With Law Enforcement Intensifies
To strengthen enforcement, the central bank is working closely with the Department of Special Investigation and the Royal Thai Police to analyze payment data and identify businesses disguising illegal financial activities as legitimate commercial operations. Websites linked to unlawful payment processing may also face immediate blocking while criminal investigations proceed.
The BOT has also established information-sharing arrangements with Chinese technology providers to detect merchants improperly using personal peer-to-peer QR codes for commercial purposes. This cooperation has already produced tangible results.
Between February 2025 and May 2026, authorities froze and terminated approximately 5,000 accounts involved in unauthorized commercial transactions using direct Renminbi transfers through personal QR payment systems. Regulators believe these actions have significantly disrupted underground payment channels facilitating grey-market capital flows.
The central bank continues encouraging consumers, financial institutions and businesses to report suspicious payment activities and unlicensed financial intermediaries through its Financial Consumer Protection Center. Officials maintain that preserving confidence in Thailand’s payment system requires constant vigilance, stronger compliance across the financial sector and swift enforcement against those attempting to exploit digital technologies for illegal financial gain. The latest crackdown signals that regulators intend to maintain a zero-tolerance approach toward illicit FOREX trading, money laundering activities and unauthorised cross-border payment networks as Thailand strengthens the integrity and transparency of its rapidly evolving digital financial landscape.
