Turkey's oil products demand remains on a solid upward trajectory and is considered to be the largest growth market in Europe. SOCAR is currently building the only grass roots refinery project in Europe - completion expected in 2018 - which will break the long-held Tupras refining monopoly. The retail landscape changed drastically in 2010 with the introduction of five year service station dealer contracts, with many of these changing brand again in 2015. Despite the country's strong growth prospects, Total announced the sale of its standalone Turkish fuels marketing business in 2015, with OMV also announcing its exit from Turkish market in 2016, selling its marketing business to Vitol. Price caps introduced by regulator EMRA in recent years have raised concerns about the long-term profitability for fuels marketers in Turkey.
