Marex Spectron, the energy and commodities broker with ambitions of becoming a “trading supergroup”, has recruited the former co-head of investment banking at Swiss bank UBS as its chief executive.

Marex Spectron, which was formed in March last year when Marex acquired Spectron, is backed by JRJ Group, a private equity firm founded by former Lehman Brothers executives Jeremy Isaacs and Roger Nagioff.
