Since the 2013 Energy Reform, which opened up Mexico’s energy sector to private investment, Petróleos Mexicanos (PEMEX) has become a state productive enterprise with the core mission of creating value. This new legislative framework granted PEMEX greater autonomy for its administration, organisation, management and budget, as well as a new corporate structure. At the same time, it changed PEMEX’s organisational structure and resulted in a series of reforms in different fields, including procurement, acquisitions, leasing, services and works, in order to give PEMEX the tools required to compete in international markets. This OECD review identifies the strengths of PEMEX procurement function and the potential options for improvement to achieve its new institutional mission and compete successfully.
