Brazil Senator Wagner Probed Over Banco Master, Carbon Bill
Brazilian federal police are investigating Senator Jaques Wagner over extensive off-the-record contacts with a figure tied to Banco Master and his brief handling of a carbon-market bill, dragging a key piece of climate legislation into a widening banking scandal.
Brazilian federal police executed 18 search warrants in June against Senator Jaques Wagner, centering on 74 voice calls he made to Augusto Ferreira Lima. Lima is the owner of Banco Pleno and a former business partner of Daniel Vorcaro, a key figure in the Banco Master group.
The warrants, authorized by Supreme Court Justice André Mendonça, targeted locations across the Federal District, São Paulo, and Bahia. Authorities allege the calls—spanning 555 days from November 2023 to May 2025 and totaling more than five and a half hours—were a calculated method to bypass written records tied to Banco Master.
A separate but related line of inquiry ties the senator to Brazil's developing carbon market. In late July, police revealed the discovery of three legislative amendments on Vorcaro’s phone that were submitted to PL 412/2022, the bill regulating Brazil's carbon market.
The police report classified these files, sent by an individual tied to an environmental credits project, as "fundamentais" to the bill's text. While the amendments were formally presented by Senator Efraim Filho, Wagner's prior role places him in the investigative spotlight. He served as the bill's rapporteur for approximately one month in November 2022.
It remains unclear if the 74 phone calls directly involved discussions about the carbon-credit legislation or if they represent a distinct line of inquiry focusing strictly on the Banco Master group. Federal prosecutors have not yet filed formal charges related to the carbon bill, and the analysis of digital and physical evidence seized in June continues.
Wagner has publicly denied any wrongdoing, explicitly stating he did not receive funds from Banco Master. His defense has not addressed the specific content of his communications with Lima.
For market participants, the investigation introduces fresh volatility into the regulatory outlook for Brazilian carbon credits. The involvement of senior political figures in the drafting of PL 412/2022 threatens to undermine institutional confidence just as the country attempts to formalize its carbon market. The case remains under Supreme Court supervision, with no indictment announced.
