The constitutional energy amendment published in the Official Gazette on December 20 2013 transformed the Mexican energy market into a competitive market that enables private investment.

As a result, gasoline and diesel prices will be liberalised after December 31 2017, as established by the new Hydrocarbon Law. In addition, the Hydrocarbon Law has enabled parties outside the Mexican Petroleum (Pemex) franchise model to sell gasoline and diesel since January 2015.
