It was at that time the first oil company, which was conducted exclusively by the state, with the exception of the Soviet Union.

Since its inception, the YPF has not only opened up numerous oil deposits, but also in building many cities made ​​important contributions, eg in Comodoro Rivadavia, Caleta Olivia, Santa Cruz, Plaza Huincul in Neuquén and General Mosconi, Salta.


In 1993, YPF was privatized in part at the behest of then-President Carlos Menem by a wide placement of shares on the stock exchange. After the privatization of the Argentine government initially held 20% of the capital. However, this privatization was controversial to a considerable extent.

In 1999, the Spanish oil company Repsol acquired the still held by the State remaining share of 14.99% and increased its share then passed through a tender offer to approximately 99 % of the capital; but the stock of YPF continued to be listed on the stock exchange.
