Who are the two US gasoline traders who recently left Vitol Group, and what were their professional backgrounds before joining the company?

The two US gasoline traders who departed Vitol Group are Calvin Greer and Phil Reiser. Greer joined Vitol four years ago after working at Susquehanna International Group, while Reiser joined three years ago to trade US Gulf Coast gasoline after spending eight years at Exxon Mobil Corp in various roles, including as a gasoline trader.

What broader organizational changes at Vitol accompanied Greer’s and Reiser’s departures?

Greer’s and Reiser’s departures coincided with the retirement of senior gasoline trader John Addison in Houston and a reorganization of Vitol’s derivatives desk in London—prompted by mark-to-market losses incurred during the early days of the Iran war—which is expected to result in some traders leaving and others being reassigned to different desks.
