Japan’s Financial Services Agency (FSA) has taken strict enforcement action against moomoo Securities, ordering the brokerage firm to stop accepting new customer accounts for three months. The decision follows an investigation that uncovered serious shortcomings in compliance procedures, anti-money laundering controls, cybersecurity management, and customer protection practices.
The suspension reflects Japan’s increasingly strict approach toward financial institutions operating in both traditional and digital finance sectors, emphasizing the importance of strong governance and regulatory compliance.
New Customer Registrations Suspended Until September
According to the FSA, moomoo Securities must immediately halt the solicitation and acceptance of new account applications from June 19 through September 18, 2026.
In addition to the suspension, regulators issued a formal business improvement order requiring the company to strengthen its internal controls, clarify management accountability, and submit a comprehensive plan to prevent similar issues from occurring in the future.
The action follows recommendations from Japan’s Securities and Exchange Surveillance Commission (SESC), which concluded that the company expanded its services without establishing adequate compliance and risk management systems.
Incorrect NISA Eligibility Information Misled Investors
One of the most significant concerns raised by regulators involved the company’s handling of Japan’s Nippon Individual Savings Account (NISA) program.
The investigation found that between early 2025 and early 2026, moomoo Securities incorrectly identified 78 U.S. exchange-traded funds (ETFs) and exchange-traded notes (ETNs) as eligible investments under the tax-advantaged NISA scheme.
As a result, some retail investors purchased products believing they qualified for tax-free treatment when they actually did not.
Regulators criticized the brokerage for failing to take sufficient corrective action after discovering the mistake. Authorities stated that the company did not proactively notify affected customers or adequately restore annual investment allowances that may have been impacted.
Anti-Money Laundering Failures Raise Concerns
The FSA also highlighted major weaknesses in the company’s anti-money laundering (AML) framework.
According to regulators, more than 1,500 account applicants who had been flagged or rejected were not properly reviewed for suspicious activity. The company reportedly operated under the mistaken assumption that AML screening requirements only applied to approved customers.
Authorities concluded that the brokerage failed to conduct required investigations and reporting procedures related to suspicious transactions over an extended period.
These shortcomings raised concerns about the effectiveness of the company’s risk management and compliance systems.
Restrictions on Customer Asset Transfers
Another issue identified during the investigation involved customer stock transfers.
Regulators found that since early 2024, moomoo Securities had declined requests from customers seeking to transfer Japanese stocks to other brokerage firms.
This practice limited customers’ ability to move their assets freely and potentially restricted investor choice, prompting additional regulatory scrutiny.
The FSA viewed these restrictions as inconsistent with customer protection standards expected from licensed financial institutions.
Cybersecurity and Governance Weaknesses
Beyond compliance concerns, authorities also identified significant cybersecurity shortcomings.
The investigation found that company management had failed to maintain a complete inventory of critical transaction systems and had not properly evaluated vulnerabilities affecting important infrastructure.
Regulators expressed concern that inadequate oversight of technology systems could expose customers and the broader financial system to operational risks.
As part of the business improvement order, the company must strengthen governance structures, improve internal controls, and establish clearer accountability among senior executives.
Improvement Plan Due in July
Moomoo Securities has been instructed to submit a detailed business improvement plan to the Financial Services Agency by July 21, 2026.
The plan must explain how the company intends to address the identified deficiencies and strengthen compliance, cybersecurity, customer protection, and anti-money laundering controls.
Regulators will closely monitor the implementation of these improvements before considering any future operational changes.
Growing Regulatory Pressure in Japan
Moomoo Securities is the Japanese subsidiary of Futu Holdings, a Hong Kong-based online brokerage listed on Nasdaq. The company has experienced rapid growth in Japan through its mobile investment platform and has attracted millions of app downloads by offering low-cost access to U.S. stock markets.
However, the latest enforcement action highlights the challenges that fast-growing financial technology companies face when expanding their operations under increasingly strict regulatory frameworks.
The decision also comes amid broader efforts by Japanese authorities to strengthen oversight of digital assets, stablecoins, and crypto-related financial services. Earlier this year, the FSA introduced additional supervisory requirements and proposed stricter standards for institutions involved in digital asset activities.
Final Thoughts
The suspension of new account openings at moomoo Securities represents one of the most significant regulatory actions taken against a brokerage firm in Japan this year. The case underscores the importance of maintaining strong compliance systems, effective anti-money laundering controls, robust cybersecurity practices, and transparent customer protection measures.
As Japan continues to tighten oversight across the financial sector, firms operating in both traditional and digital finance markets are likely to face increasing scrutiny. For moomoo Securities, the coming months will be critical as it works to address regulatory concerns and restore confidence among customers and regulators alike.
