Groundbreaking Verdict: Singapore Jails Former Fund Manager for Fraudulent OTC Bond Trading


Historic Conviction in Singapore for Fraudulent Bond Trading

In a landmark ruling, the Monetary Authority of Singapore (MAS) has reported a pioneering conviction regarding deceptive practices in over-the-counter (OTC) bond trading. This case marks the first time an individual has been held accountable under Singapore’s stringent Securities and Futures Act for such offenses. The conviction underscores Singapore’s commitment to maintaining integrity and trust within its financial markets.

Sun Weiyeh, a prominent figure in the investment landscape as the former fund manager and director at One Asia Investment Partners (OAIP), has been sentenced to six months in prison. The conviction, finalized on April 11, 2024, came as a result of Weiyeh’s engagement in deceitful trading activities which resulted in substantial financial loss for investors.

The misconduct centered around the sale of two OTC bonds. Weiyeh executed trades that transferred these bonds from one fund managed by OAIP (Fund A) to another fund (Fund B), in which he had a substantial personal stake, at prices below their market value. Despite higher bids being previously available, Weiyeh chose to sell the bonds at a profit to the market, leading to a collective loss of US$342,500 for the investors in Fund A.

The fraudulent operations utilized the Bloomberg messaging system for solicitation of offers from potential participants in the market. By intentionally referencing lower bids to facilitate the sales from Fund A to Fund B through an intermediary, Weiyeh bypassed higher bidder offers, which would have brought greater returns to Fund A investors.


The conviction followed a meticulous 26-day trial that stemmed from an extensive investigation led by the MAS in collaboration with the Commercial Affairs Department of the Singapore Police Force. This sentencing not only sheds light on the precise mechanisms of the fraud but also emphasizes the rigorous enforcement landscape within Singapore’s financial markets.

Loo Siew Yee, the Assistant Managing Director (Policy, Payments, and Financial Crime) at MAS, commented on the conviction, underlining the fundamental obligation of financial sector professionals to act in the best interests of their clients. “As a director and portfolio manager of the fund management company, Mr. Sun owed a duty to its investors to act in their interest at all times,” Loo stated. She further elaborated on MAS’s unwavering stance towards any form of misconduct, ensuring that individuals exploiting their positions for personal gain, to the detriment of investors, would face strict consequences.

The case serves as a stern reminder of the importance of ethical practices in the financial industry and the severe repercussions awaiting those who seek to undermine the principles of fairness and transparency. With this conviction, Singapore reaffirms its reputation as a stalwart defender of investor interests and a bastion against financial crimes. Such enforcement actions are essential in fostering a secure and robust financial system, both locally and on the international stage.
