Japan’s SESC Recommends Administrative Penalties for Moomoo Securities Over NISA Violations and Systemic Failures
Japan’s Securities and Exchange Surveillance Commission (SESC) has recommended administrative action against Tokyo-based Moomoo Securities. The recommendation, submitted to the Prime Minister and the Commissioner of the Financial Services Agency (FSA), follows an agency investigation that uncovered severe compliance breaches, misleading retail practices, and systemic operational deficiencies at the online brokerage.
Misleading NISA Practices and Poor Remediation
According to the regulator, Moomoo Securities launched internet-based trading services for retail investors in October 2023, expanding to offer tax-free Nippon Individual Savings Accounts (NISA) in January 2024. Driven by aggressive marketing campaigns offering perks like free stock, the firm experienced rapid user growth.
However, the SESC’s inspection revealed that between February and May 2025, the broker mislabeled 77 non-eligible US ETFs and ETNs as NISA-compliant on its platform due to a lack of internal controls and an inadequate understanding of tax regulations. This led to 59 clients mistakenly executing trades through tax-exempt accounts.
Furthermore, after being alerted to the issue and temporarily halting sales, Moomoo Securities failed to establish proper oversight mechanisms. Consequently, the firm repeated the infraction between November 2025 and January 2026, selling another ineligible US ETF under the guise of a NISA-approved product. The SESC has categorized this as a violation of the Financial Instruments and Exchange Act (FIEA) regarding the provision of false information during contract conclusions.
The regulator also heavily criticized the firm's remediation efforts as "grossly negligent" and "discriminatory". The brokerage allegedly misinformed affected clients regarding transfer options due to system limitations, failed to correct annual tax-free investment quotas for 58 out of the 59 impacted investors for months, and prioritized a single complaining client over others due to a lack of human resources.
Breach of Fiduciary Duty and AML Shortfalls
The probe also highlighted a breach of the "duty of care of a good manager" under the FIEA. Since April 2024, Moomoo Securities has maintained a blanket ban on domestic stock transfer-out requests from its clients, falsely treating transfer services as optional rather than a regulatory obligation. Similar restrictions were placed on mutual fund transfers starting September 2024. Despite publicizing on its website that it would resolve the issue, the firm had taken no concrete steps or allocated a budget to implement the necessary transfer systems.
Additionally, the firm failed to review or report suspicious transactions under the Act on Prevention of Transfer of Criminal Proceeds. Between September 2023 and July 2025, the firm neglected to assess at least 1,531 instances involving clients whose account applications were rejected, operating under the incorrect assumption that anti-money laundering (AML) obligations did not apply to rejected applicants.
Systemic Risk and Governance Failures
The SESC concluded that Moomoo Securities suffers from extensive cybersecurity and system risk management failures. Key issues cited include:
- Inadequate risk assessments, leaving core IT infrastructure unlisted in asset registries.
- Deficient cybersecurity protocols, including a lack of prioritized vulnerability patching and untested cyberattack contingency plans.
- Insufficient human resources to track system outages or conduct effective independent system audits.
The regulator pointed out that the firm’s Information Security Committee (chaired by the CEO) and senior management were aware of these technical and compliance vulnerabilities for years but neglected to issue corrective directives, prioritizing rapid business expansion over investor protection and legal compliance.
Given these deep-seated managerial and internal control failures, the SESC has called for immediate administrative intervention to protect the public interest and safeguard retail investors.
