Why Are Thai Crypto Exchanges Freezing Accounts?

Cryptocurrency platforms in Thailand have frozen more than 10,000 accounts suspected of being used for laundering illicit funds as authorities intensify efforts to shut down so-called mule accounts in the digital asset market.

The freezes followed the rollout of stricter screening measures designed to slow suspicious transfers and trigger additional Know Your Customer checks for higher-risk transactions. According to local reporting from the Bangkok Post, the tighter controls helped exchanges identify accounts linked to potential money-laundering activity.

Att Thongyai Asavanund, chief executive of KuCoin Thailand and chairman of the Thai Digital Asset Operators Trade Association (TDO), said the new monitoring process allowed operators to detect thousands of suspect accounts. “The tighter process helped operators identify and freeze more than 10,000 suspected mule accounts,” he told the Bangkok Post.

The action forms part of a broader enforcement effort involving financial regulators, banks and law-enforcement agencies as Thailand works to close loopholes in digital-asset transfers.

Investor Takeaway

Thailand’s crackdown shows that crypto exchanges in regulated markets are tightening compliance controls quickly, which may raise onboarding friction but reduce regulatory risk for the industry.

How Large Is the Mule Account Problem?

The latest account freezes add to a much larger enforcement effort already underway. Thai authorities previously reported that nearly 48,000 mule accounts connected to digital asset activity were frozen during 2025 as part of coordinated investigations.

Mule accounts typically involve individuals allowing their accounts to be used to move illicit funds, often in exchange for a fee. In the crypto sector, such accounts can be used to move funds between exchanges or wallets in ways that attempt to obscure the origin of transactions.

Because digital assets can move quickly across platforms and jurisdictions, regulators increasingly rely on exchange-level monitoring and identity checks to identify suspicious transaction patterns.

What Role Do Regulators and Exchanges Play?

Thailand’s Securities and Exchange Commission has been working closely with the Thai Digital Asset Operators Trade Association, which represents licensed crypto exchanges and brokers in the country. The cooperation has focused on improving monitoring standards and creating a unified framework for identifying suspicious activity.

During a February 2025 workshop involving regulators, police agencies and banking organizations, authorities outlined new measures aimed at tracking mule accounts across both the banking and crypto sectors.

SEC Deputy Secretary-General Jomkwan Kongsakul said regulators and industry participants had already established monitoring guidelines. “The SEC and the TDO have jointly developed guidelines for monitoring and investigating suspicious accounts,” she said at the time.

She added that the agencies had also introduced accelerated procedures to deal with different types of mule accounts more quickly.

Investor Takeaway

Cooperation between crypto exchanges, banks and law enforcement is becoming standard practice in regulated markets, increasing the likelihood that suspicious accounts will be detected earlier.

What Other Measures Are Being Introduced?

Thai authorities are expanding data-sharing arrangements between digital-asset platforms, banks and law-enforcement agencies to help identify accounts suspected of facilitating illegal transfers. The goal is to prevent funds from moving between platforms once suspicious activity is detected.

The crackdown also aligns with a wider government campaign targeting so-called “gray money,” a term used to describe financial flows that fall outside normal regulatory oversight. Earlier this year, officials said enforcement efforts would cover digital assets as well as physical gold trading and other channels sometimes used to move unreported funds.

For crypto platforms, one key requirement involves strict enforcement of the Travel Rule. The regulation requires licensed service providers to collect and transmit identifying information about the sender and recipient of certain digital asset transactions. This is especially relevant for transfers between wallets facilitated by exchanges.

What Comes Next for Thailand’s Crypto Market?

The latest account freezes suggest Thailand’s regulatory approach is moving toward deeper monitoring rather than outright restrictions on digital assets. Exchanges remain legal and licensed operators continue to work under a regulatory framework overseen by the Securities and Exchange Commission.

However, compliance expectations are rising as authorities focus on cross-platform transaction monitoring and identity verification. That trend mirrors developments in other major crypto markets, where regulators are pushing exchanges to strengthen anti-money-laundering controls and data sharing.

For Thailand’s digital-asset industry, the enforcement campaign highlights a growing emphasis on operational compliance. Exchanges that can meet stricter monitoring requirements may face higher compliance costs, but they also reduce the risk of regulatory intervention that could disrupt trading activity.
