The Vitol Group is a Dutch energy and commodity trading company that was founded in Rotterdam in 1966 by Henk Viëtor and Jacques Detiger.
Though physical trading, logistics and distribution are at the core of the business, these are complemented by refining, shipping, terminals, exploration and production, power generation, and retail businesses.
Vitol has 40 offices worldwide and its largest operations are in Geneva, Houston, London, and Singapore. With revenues of $231 billion in 2018, it is the largest independent energy trader in the world, and would rank ninth on the Fortune Global 500 list.
The company ships more than 350 million tonnes of crude oil per year and controls 250 supertankers and other vessels to move it around the world. On average it handles more than 7 million barrels a day of oil and products – roughly equivalent to the daily consumption of Japan – the world's third largest oil consumer after the United States and China.
Vitol is a private company which is owned significantly by a proportion of its employees, who are known for their culture of privacy and secrecy, from both competitors and the general public.
