Funaro was the son of Paschoal Funaro and Helena Kraljevic, and grandson of Domingos Funaro. Coming from a wealthy family, he studied engineering at Mackenzie Presbyterian University, and while still at a young age joined CIBRAPE, an industrial concern specialized in plastics. Not long after he acquired Monitora and later Trol, a major manufacturer of plastics for industry, domestic use, and toys. In October 1982, Funaro discovered that he was suffering from lymphatic cancer, and that it was a particularly serious form of the disease. Despite receiving treatment, he suffered a number of relapses that eventually led to his death in 1989. He was married to and survived by Ana Maria Matarazzo Suplicy, with whom he had six children.
Plano Cruzado
After serving in a number of posts in both industry and government over two-and-a-half decades, Funaro was appointed head of the Brazilian Development Bank in March 1985 at the request of President Sarney. That August, Sarney promoted him to head the Finance Ministry, the first minister that the president personally appointed after inheriting his cabinet from deceased President-elect Tancredo Neves. Funaro was quickly recognized as the most powerful member of Sarney's government in the first months of his tenure, and used his wide-ranging power to tackle Brazil's explosive monetary inflation problem. These reforms were packaged as the Plano Cruzado, after the new currency that was introduced as the centerpiece of the initiative. It also included a freeze on wages and prices and an end to the system of automatic price increases known as indexing. When the plan proved unable to stem inflation, Funaro switched tactics and created what was dubbed "Plano Cruzado II" which undid many of the previous reforms as well as raised taxes to curb the public demand for goods that had been generated by the revoking of indexing. This turnabout made the minister increasingly unpopular among the common citizens as well as politicians from rival parties. When Funaro became convinced that Brazil's debt to foreign banks was making it impossible to generate economic growth, he convinced the Government to suspend interest payments on $67 billion worth of loans on February 20, 1987. This created panic in the international banking community, especially in the United States, over concerns that Brazil would be able to repay any of its loans. By April 1987, Funaro's position became untenable and he resigned on the 29th. He was unable to recover politically from this setback before his death just two years later.
