Singapore MAS Issues 7-Year Ban on ex-One Asia Investment Partners (OPIA) Fund Manager & Director Sun Weiyeh after 6-Month Jail Sentence Conviction for Committing Fraud on Investors of OAIP (Fund A), Sold 2 OTC Bonds at Lower Prices in OAIP (Fund A) to Another OAIP Fund (Sun Weiyeh is Majority Shareholder) Resulting in $342,500 Losses to Investors in OAIP (Fund A)
14th January | Hong Kong
Monetary Authority of Singapore (MAS) has issued a 7-year ban (Prohibition Order) on ex-One Asia Investment Partners (OPIA) fund manager & director Sun Weiyeh after his 6-month Singapore court jail sentence conviction for committing fraud on investors of OAIP (Fund A), selling 2 OTC bonds at lower prices in OAIP (Fund A) to another OAIP fund (Sun Weiyeh is majority Shareholder) resulting in $342,500 losses to investors in OAIP (Fund A). Announcement (14/1/26): “The Monetary Authority of Singapore (MAS) has issued a 7-year prohibition order (PO) under the Financial Services and Markets Act 2022 (FSMA) against Mr Sun Weiyeh, a former fund manager and director of One Asia Investment Partners (OAIP). Mr Sun intentionally sold two over-the-counter bonds at lower prices from a fund managed by OAIP (Fund A), which was majority held by external investors, to another OAIP-managed fund, of which he was the majority shareholder. He did this while knowing that there were higher prices quoted for the bonds, causing a loss of US$342,500 to investors in Fund A. Subsequently, Mr Sun resold the two bonds to the market at a profit. Mr Sun was charged and convicted in July 2024 of committing acts which were likely to operate as a fraud on Fund A’s investors. On appeal, the High Court in July 2025 upheld his conviction and the 6-month imprisonment sentence imposed by the State Courts. In view of his offences, MAS is satisfied that Mr Sun is not a fit and proper person, in accordance with the Guidelines on Fit and Proper Criteria under section 7 of the FSMA. Under the PO, effective 9 January 2026, Mr Sun is prohibited for 7 years from carrying on or providing any MAS regulated or authorised activity or business from participating (directly or indirectly) in the management of any financial institution, and from acting as a director, partner or manager, of any financial institution. He is also prohibited from becoming, or increasing his interest as a substantial shareholder of any financial institution that is a corporation, and from performing any function involving handling of funds or assets.”
