JPMorgan Chase and UBS ended prime brokerage services for Hong Kong hedge Infini Capital Management months before authorities publicly disclosed an insider trading investigation involving the firm, according to a report by the Business Times citing unnamed sources familiar with the matter.
Along with Standard Chartered, the banks had been listed as Infini’s prime brokers in a March 2025 SEC filing. It is unclear whether other banking services were affected.
Hong Kong regulators and the city’s anti-graft agency this week announced eight arrests linked to a HKD315m corruption and insider trading case. Sources said offices of Infini Capital Management, Citic Securities, and Guotai Junan International were raided.
The investigation alleges that brokerage executives accepted over HKD4m in bribes from a hedge fund manager in exchange for confidential information on share placements. Infini has acted as a major buyer in Hong Kong equity capital markets, sometimes as the sole participant. Three of its executives have been unreachable, and their ongoing deals are reportedly on hold.
Founded in 2015 by former Morgan Stanley and HSBC Holdings banker Tony Chin, Infini began as a proprietary trading firm and later opened to external capital, offering a range of trading strategies.
