RJ O’Brien has parted ways with its head of Europe Emre Degirmenci just 14 months after he joined the Chicago-based broker from rival Marex.

Degirmenci, who became managing director of Europe, the Middle East and Africa at London-based RJ O’Brien Limited in September 2020, left that position last week, according to sources.

A spokeswoman for RJ O’Brien in Chicago confirmed the move.

Before RJO, Degirmenci was group treasurer at Marex, a position he held from 2014 until his resignation in May last year. In that role, he managed the British firm’s treasury strategy and policy, group liquidity, and capital and currency exposure.

Before joining Marex, Degirmenci spent nearly four years in various treasury roles at RBS in London and more than 15 years at Citigroup working in treasury and risk management in New York, Singapore and Istanbul.

The departure leaves RJO Limited facing its fourth European head in under six years. Before Degirmenci, Thomas Texier ran the European business for almost three years before leaving at the start of last year to join Marex.

Texier replaced David Mudie who was head of RJO EMEA for almost four years until he left the firm in the middle of 2016.

Degirmenci's departure marks the latest senior management change at RJO this year.

The broker promoted in July Terry Gilhooly to global chief operating officer (COO) from his former role as COO of North America.

RJO moved in June its head of sales Daniel Staniford to the newly reinstated post of president, reporting to the Chicago-based firm’s chair and chief executive Gerald Corcoran.

RJ O’Brien named in April Christopher Bove, the former lead Investigator in CME Group’s Market Regulation department, as the firm’s new chief compliance officer.
