In December 2002, Prat-Gay was named as President of the Central Bank of Argentina, at only 37 years of age, and served until September 24, 2004. He won the 2004 Euromoney Central Bank Governor of the Year award for his work for having reduced the inflation from 40% to 5% while maintaining an economic growth of 8%.

He joined the Civic Coalition, led at the time by Elisa Carrio, and was named as Carrio's choice for Economy Minister had she won the 2007 presidential election. Prat-Gay led the Civic Coalition's party list for the city of Buenos Aires in the 2009 congressional elections, and was handily elected. As a Congressman, he worked on projects such as increasing banking security, preventing money laundering and drug trafficking, and an extensive deregulation of the Argentine financial system.

Prat-Gay is Chairman of Tilton Capital, an asset management company he co-founded in 2005 with Pedro Lacoste. He is president of Fundacion Andares para el desarrollo de las Microfinanzas ("Paths toward the Development for Microfinancing"). His clients at Tilton Capital included the late María Amalia Lacroze de Fortabat, former chairperson of Argentina's largest concrete manufacturer, Loma Negra. Prat-Gay's work for Mrs. Fortabat came under scrutiny after revelations that Tilton Capital facilitated tax evasion and capital flight for Fortabat and other clients, including the entirety of Mrs. Fortabat's billion-dollar payout for her sale of Loma Negra in 2005. The vice president of JP Morgan Argentina at the time, Hernán Arbizu, declared that Prat-Gay managed much of this wealth in a offshore hedge fund of his creation with put options against the Argentine peso. He was appointed executor of the Lacroze de Fortabat estate following Mrs. Fortabat's death in 2012.

Prat-Gay co-founded the Juntos UNEN ('Together They Unite') alliance with centrist UCR Congressional caucus leader Ricardo Gil Lavedra, and Victoria Donda of the leftist Freemen of the South Movement in January 2013. He declared his candidacy in July for a seat in the Argentine Senate ahead of the 2013 mid-term elections.
