Update 3/9/2026 – Igor Abramov, former U.S. chief compliance officer at Capula Investment Management based in London, has refiled his whistleblower lawsuit in New York State court. This comes after his federal case was dismissed due to jurisdictional grounds.
The complaint was filed in March 2, 2026 under New York Labor Law Section 740, and it accuses Capula of a “pattern of intimidation” aimed at preventing Abramov from carrying out his regular duties as chief compliance officer. The case also alleges that the firm retaliated against him by firing him when he blew the whistle on some allegedly unsavory practices.
Those practices were said to include “certain undisclosed and improper expenses” that Capula allegedly charged to investors in the Capula Multi-Strategy Master Fund Limited. The lawsuit also accuses the firm of some “improper cross trading and capital allocations by Capula of the assets of the Capula Global Relative Value Fund, to the detriment of the GRV Fund investors.”
Other allegations include accusations of wrongful “test trades” that improperly risked investor assets in the MS fund. The lawsuit states that all of these practices violated federal law, including SEC regulations.
