Japan’s Financial Services Agency (FSA) has ordered moomoo Securities to halt new account openings for three months after uncovering a series of compliance, anti-money laundering (AML), and cybersecurity shortcomings, adding fresh scrutiny to firms operating across traditional and digital finance markets.
The regulator announced on June 19 that the brokerage will be prohibited from soliciting or accepting new account applications from June 19 to Sept. 18. The FSA also issued a business improvement order, requiring the company to strengthen internal controls, clarify management responsibility, and submit a corrective action plan by July 21.

The enforcement action follows an investigation by Japan’s Securities and Exchange Surveillance Commission (SESC), which found that the company expanded its services without establishing sufficient compliance and risk management systems.
Regulators find NISA-related investor protection failures
According to the SESC, moomoo Securities incorrectly labelled dozens of U.S. exchange-traded funds (ETFs) and exchange-traded notes (ETNs) as eligible for Japan’s Nippon Individual Savings Account (NISA) program, a tax-advantaged investment scheme.
Authorities said 78 products were displayed as NISA-eligible on the firm’s trading app between early 2025 and early 2026, leading some retail investors to purchase assets that did not qualify for tax-free treatment.
Regulators also criticized the company’s response after the error was discovered, stating that affected customers were not adequately informed and corrective measures were not taken promptly.

AML lapses draw regulatory attention
The investigation also identified significant weaknesses in the brokerage’s anti-money laundering framework.
The SESC found that more than 1,500 rejected or flagged account applicants were not properly reviewed for suspicious activity because the company incorrectly believed AML screening obligations applied only to approved accounts.
Authorities said the firm failed to conduct required checks and reporting procedures related to potentially suspicious transactions over an extended period, raising concerns about its compliance controls.
Cybersecurity issues surface as crypto oversight increases
Beyond compliance failures, regulators cited weaknesses in cybersecurity governance, including inadequate oversight of important transaction systems and vulnerability management.
The case comes as Japan increases supervision of digital asset activities, including proposed rules for stablecoin reserves and stricter oversight of institutions involved in cryptocurrency services.
The FSA introduced a new regulatory framework earlier this month. The new system creates a category called “electronic payment instrument and crypto asset service intermediary business,” allowing firms to legally provide limited crypto-related services under a lighter registration structure.
Moomoo Securities is the Japanese subsidiary of Nasdaq-listed Futu Holdings. While the enforcement action targets the brokerage’s operations in Japan, it arrives as other Futu-affiliated businesses, including crypto platform Moomoo Crypto, continue expanding services in the United States.
What happens after September 18?
The FSA has not described the action as a permanent withdrawal of Moomoo’s licence. Existing customers can continue using their accounts, while the company works through the corrective measures imposed by the regulator.
Moomoo is operated in Japan by a subsidiary of Hong Kong-based Futu Holdings and had expanded quickly in the Japanese retail-investing market. Its app had passed two million downloads as the company built its presence around mobile trading and access to US stocks.
For Japan’s financial sector, the case is also a warning to digital brokerages and fintech platforms that rapid customer growth does not reduce traditional obligations around AML, investor protection, cybersecurity and internal governance. Moomoo’s suspension is more about whether a fast-growing digital brokerage can build the controls expected of a regulated financial institution.
