López Portillo studied law at the National Autonomous University of Mexico before beginning his political career with the Institutional Revolutionary Party (PRI) in 1959. He held several positions in the administrations of his two predecessors before being appointed to serve as finance minister under Luis Echeverría from 1973 to 1975.

As president, he oversaw the initial exploitation of newly discovered oil fields in the states of Veracruz and Tabasco. In spite of the massive amounts of foreign exchange these discoveries earned for the state-owned oil company Pemex, López Portillo's administration oversaw rampant corruption, excessive overseas borrowing, hyperinflation, and violent devaluations of the peso.

One of his last actions as president, announced during his annual State of the Nation address on September 1, 1982, was to order the nationalization of the country's banks.
