Japan’s primary financial regulator has taken enforcement action against Moomoo Securities. The Financial Services Agency (FSA) has ordered the online brokerage to halt new account openings for three months after uncovering a series of compliance and governance failures.
According to the local report, the partial business suspension, announced on June 19, 2026, against the Tokyo-based subsidiary prevents the company from soliciting or accepting new customer account applications, effective June 19, 2026 through September 18, 2026. The regulator also imposed a business improvement order requiring the company to strengthen its internal control systems and submit a detailed remediation plan.
False NISA marketing triggers regulatory action
According to the FSA, one of the most serious violations involved misleading customers about eligibility under Japan’s popular Nippon Individual Savings Account (NISA) program.
Regulators found that Moomoo promoted certain investment products as NISA-eligible even though they did not qualify under the tax-advantaged scheme.
Japan’s Financial Instruments and Exchange Act prohibits financial institutions from making false or misleading statements when soliciting customers or entering into investment contracts.
The findings follow earlier reports that Japan’s Securities and Exchange Surveillance Commission (SESC) was preparing to recommend disciplinary measures against the brokerage over the same issue.
AML and cybersecurity controls found lacking
Beyond the NISA-related violations, the FSA said Moomoo failed to properly verify and report suspicious transactions for an extended period. The regulator also identified deficiencies in the company’s anti-money laundering controls and cybersecurity framework.
According to the agency, multiple weaknesses were discovered within the firm’s governance structure, raising concerns about its ability to effectively manage operational and compliance risks.
As part of the improvement order, Moomoo must clarify management accountability, strengthen oversight mechanisms, and implement measures to prevent similar incidents from recurring.
FSA demands internal reforms
The business improvement order requires the brokerage to overhaul its internal controls and provide regulators with a comprehensive plan outlining corrective actions. The FSA emphasized that management bears responsibility for the deficiencies and must take concrete steps to rebuild compliance systems and strengthen risk management practices.
The enforcement action highlights Japan’s increasingly strict stance toward investor protection and financial compliance as digital brokerages continue expanding their presence in the market.
Moomoo’s rapid growth faces regulatory setback
Moomoo Securities is the Japanese subsidiary of Hong Kong-listed brokerage giant Futu Holdings, a Nasdaq-traded financial technology company. The platform has gained popularity in Japan through its mobile-first trading application, which has reportedly surpassed 2 million downloads nationwide.
The brokerage aggressively expanded its customer base by offering some of the lowest trading fees in the industry, particularly for U.S. equities. However, the latest regulatory action threatens to slow that growth momentum as the company addresses concerns over compliance, customer disclosures, and operational controls.
For Moomoo, the next three months will likely be focused on rebuilding regulatory trust while implementing the reforms required to resume normal business operations.
