During the presidency of Raúl Alfonsín, in June 1985, Colombo was appointed as president of the Banco Nacional de Desarrollo (BANADE), in replacement of Mario Brodersohn. Later, Colombo worked in the private sector as part of Gupo Pérez Companc, as a stockbroker in the Buenos Aires Stock Exchange, as vice president of the Sociedad de la Bolsa Macro, and as manager of the Banco Río de la Plata (later Banco Santander Río) stock market.[1][2]
Colombo remained in the position until De la Rúa's abrupt resignation on 20 December 2001, and was the last public official to leave the Casa Rosada in the aftermath of the December 2001 riots.[6] Due to Senate provisional president (and acting president) Ramón Puerta being in San Luis at the time, Colombo managed "security and minimal administrative affairs of the State until the situation was resolved" in the early hours of 21 December.[7]
