France is a mature market in which overall oil demand is in slow but steady decline. Overall, there is a diesel/gasoil deficit in the domestic market relative to its local refinery product output, although it retains a gasoline surplus. Due to successive reductions in the refining system, its product deficit has doubled in a decade. In fuel retail, France remains one of the most competitive markets in Europe with the hypermarkets continuing to exert downward pressure on margins through its discount fuel offering. These companies control around two-thirds of the retail market. Domestic refiner Total has the largest individual network with almost 3,500 sites, nearly double that of any other player. The majority of the other oil majors, however, have now exited the market. This has seen the arrival of specialist independent fuel retailers, which leverage brand licencing agreements and the branded wholesale model.
