Vitol said last year 80% of its revenues came from oil and refined products. For Gunvor and Trafigura, their traded oil volume was around 70% each. For Glencore, oil accounts for around half of its traded volumes while metals and coal account most of the remainder.

Of the big trading groups, Mercuria stands alone with power, gas and emissions accounting for two thirds of its traded volumes, according to its 2018 results.
