The Monetary Authority of Singapore (MAS) has announced a series of significant enforcement actions taken in the fourth quarter of 2025, targeting insider trading, insurance fraud, and regulatory breaches. These actions underscore MAS’s commitment to maintaining the integrity of Singapore’s financial centre.
In October, MAS, in collaboration with the Commercial Affairs Department of the Singapore Police Force, charged Xie Jianfeng with insider trading and deception related to Sasseur Real Estate Investment Trust. Additionally, MAS issued three-year prohibition orders against Tham Kok Tong, Marcus, and Charles Chong Yong Qin, former representatives of Great Eastern Financial Advisers, for failing to meet Fit and Proper conditions.
Further actions included a civil penalty of $36,500 (S$50,000) imposed on Tan Tee Beng for insider trading in Tee International Limited and Tee Land Limited shares. MAS also issued prohibition orders against Benjamin Song Junde and Charn Sze Choong for insurance fraud, and against Tang Boon Hai for false trading and other offences.
In a significant move, MAS revoked the Capital Markets Services Licence of One Heritage Capital Management (SG) Pte Ltd due to breaches of the Securities and Futures Act 2001. November saw a civil penalty of $100,000 (S$137,000) imposed on Ang Yew Jin Eugene for insider trading in Alpha Energy Holdings Limited shares.
These enforcement actions highlight MAS’s rigorous approach to deterring misconduct and safeguarding Singapore’s financial sector.
