The Nigerian Exchange Limited (NGX) has fined five brokerage firms for market manipulation and price distortion, imposing cumulative fines of ₦291.29 million alongside corrective measures to strengthen market discipline.
In a notification dated March 27, 2026, NGX Regulation Limited (RegCo) informed the Securities and Exchange Commission Nigeria (SEC) that the penalties followed investigations into trading activities between February and March 2026.
The probe uncovered recurring infractions, including wash trades, self-matching transactions, and artificial price formation, practices deemed to mislead the market and violate provisions of the Investments and Securities Act 2025.
Among the affected firms, CSL Stockbrokers Limited received the highest fine of ₦91.29 million. Cowry Securities Limited, Meristem Stockbrokers Limited, SMADAC Securities Limited, and Associated Asset Managers Limited were each fined ₦50 million.
Beyond monetary penalties, the firms have been directed to undergo mandatory compliance and market conduct training aimed at addressing internal control weaknesses and improving adherence to regulatory standards. The NGX also stated that the sanctions are proportionate to the violations and intended to deter future misconduct, reaffirming its commitment to maintaining a fair and transparent market.
The development comes amid a broader regulatory crackdown following the enactment of the ISA 2025, which has strengthened enforcement powers across Nigeria’s capital market.
In a related case, NGX had recently suspended trading in the shares of Zichis Agro-Allied Plc over suspected price manipulation after the stock surged by over 800 percent within a month of listing. Although no parties were eventually indicted, corrective measures were introduced to preserve market integrity.
Recent enforcement data further highlights the tightening regulatory stance. NGX RegCo’s X-Compliance Report showed that 34 listed companies paid ₦540.37 million in penalties for late financial filings between 2024 and 2025. Additionally, 13 insurance firms were fined ₦378 million for disclosure breaches.
Market stakeholders have welcomed the tougher approach, noting a shift from passive oversight to active policing of the market.
Speaking on the development, legal practitioner Raphael Udo described the sanctions as a proper use of statutory powers under the ISA 2025 to protect investors and uphold market integrity. Similarly, Blakey Ijezie, founder of Okwudili Ijezie & Co., commended regulators for enforcing rules more rigorously than in the past.
However, some stakeholders called for stricter penalties, including jail terms for severe infractions such as market manipulation, warning that such practices could erode investor confidence.
Market manipulation remains a sensitive issue in Nigeria, having played a major role in the 2008 Nigerian stock market crash, which wiped out over ₦8 trillion in investor wealth. Regulators say the current enforcement drive aims to prevent a repeat of past crises by strengthening transparency, improving market discipline, and restoring investor trust.
