Thailand Tightens Crypto Oversight as Exchanges Freeze Thousands of Mule Accounts in Sweeping Anti-Money Laundering Drive

Thailand’s digital asset sector is intensifying its campaign against financial crime after local crypto exchanges froze more than 10,000 suspicious accounts under a newly introduced control mechanism designed to slow illicit transactions and disrupt organized money laundering networks.

The measure, known as the “Speed Bump,” has been implemented by members of the Thai Digital Asset Operators Trade Association (TDO) and reflects growing pressure across the global crypto industry to strengthen safeguards against financial abuse. Authorities and industry leaders say mule accounts, often used by criminal organizations to move illicit funds through complex transaction chains, remain one of the most persistent vulnerabilities in digital finance.

Att Thongyai Asavanund, chief executive of KuCoin Thailand and chairman of the TDO, described mule accounts as a critical weak point within the crypto ecosystem. Criminal groups typically route funds through multiple bank accounts before consolidating the money into a single account that transfers the assets to a cryptocurrency exchange. Once deposited on a platform, the funds are rapidly converted into digital assets and transferred abroad, making recovery far more difficult.

The Speed Bump mechanism aims to interrupt this rapid movement of funds. Under the new rule, transactions of 50,000 baht or more are automatically paused for 24 hours, during which users must complete additional identity verification procedures before the transfer can proceed. The extra screening includes enhanced know-your-customer checks such as video verification, a step designed to confirm that the account holder is the legitimate user behind the transaction.

Industry officials believe the delay undermines the speed that laundering networks depend on to move money across multiple accounts before suspicious activity is detected. According to data cited by the association, the strengthened screening measures have already led to the freezing of thousands of accounts suspected of functioning as mule accounts.

The scale of the issue is significant. Thai digital asset operators reportedly froze nearly 47,700 mule accounts throughout 2025 alone, highlighting the extent to which financial crime networks have attempted to exploit crypto platforms for cross-border transfers.

While the new system has proven effective at identifying suspicious behavior, it has also increased operational challenges for exchanges. Compliance teams must now manage growing volumes of frozen accounts, investigate unusual activity and handle user verification procedures that require additional time and resources.

Criminal organizations, meanwhile, are adapting. Industry officials say some groups attempt to recruit new individuals to open replacement accounts once previously used accounts are blacklisted, creating a continuous cycle that forces platforms to remain vigilant.

The anti-money laundering push is part of a broader effort by Thailand to strengthen regulatory oversight while continuing to position itself as a regional hub for digital finance. The TDO is working closely with regulators to connect suspect account databases with the Bank of Thailand’s payment systems and law enforcement agencies. The goal is to improve the screening of individuals considered high risk and prevent them from entering the financial system through multiple channels.

At the same time, authorities are exploring initiatives designed to encourage legitimate crypto activity. Programs such as TouristDigiPay allow foreign visitors to convert cryptocurrency into Thai baht for spending during their stay, provided they open accounts with licensed digital asset businesses and complete strict identity checks.

Thailand has also approved a five-year tax exemption on cryptocurrency profits for domestic traders in an effort to stimulate local investment after stricter tax rules dampened foreign inflows. In parallel, the Thai Revenue Department is preparing to adopt the Crypto-Asset Reporting Framework, an international standard that enables cross-border sharing of digital asset account information.

Together, these initiatives signal a delicate balancing act. Thailand is attempting to support innovation in digital finance while ensuring that crypto platforms do not become gateways for illicit capital.
