The successful investigation and prosecution of high-level corruption crimes often requires access to detailed financial intelligence, which in turn requires close cooperation and information-sharing between law enforcement officials and financial intelligence units. This has certainly been the case in Brazil, where the Lava Jato (Car Wash) investigation—considered the most successful anticorruption operation in Brazilian history—has been made possible in large measure by the reports supplied to federal prosecutors by Brazil’s financial intelligence unit, known as the Counsel of Control of Financial Activities (COAF). COAF, created in 1998, has provided Brazilian federal prosecutors with suspicious activity reports on potential targets of the Lava Jato investigation, including politicians, high-level public officials, corporations, and business executives. And in the early days of the administration of President Bolsonaro, who positioned himself as an anticorruption champion during the election, there were some signs that COAF’s role in supporting law enforcement efforts would be strengthened. President Bolsonaro, for example, proposed transferring COAF from the Ministry of Economy to the Ministry of Justice—a signal that COAF would continue to work in the support of law enforcement activities—though the Congress rejected this proposal. President Bolsonaro’s Justice Minister, Sergio Moro, also nominated an auditor of the Brazilian Internal Revenue Service who worked in Lava Jato to be the new COAF chief.
But over the course of the last year, the ability of COAF to support anticorruption investigations has been jeopardized, partly by a judicial ruling, but also by other less visible efforts by the administration to undermine the unit’s autonomy.
