Banco do Brasil (BB) has officially denounced a video by federal deputy Eduardo Bolsonaro for spreading fake news, urging the Attorney General's Office (AGU) to take action to prevent a potential bank run. According to the bank, the video, shared with over 1.7 million followers on YouTube on August 20th, falsely claims that BB will be cut off from international relations, leading to its bankruptcy.

This incident is linked to the broader implications of the Magnitsky Act, a U.S. law that allows for sanctions against individuals and entities involved in corruption or human rights violations. The narrative surrounding the Magnitsky Act has been used to spread fake news targeting banks, inciting customers to withdraw their funds en masse. The situation has already caused significant market reactions, with the shares of major Brazilian banks, including Banco do Brasil, Bradesco, Itaú, Santander, and BTG, experiencing substantial drops. For instance, on August 19th, these five institutions collectively lost R$ 41.98 billion in market value.

BB's complaint to the AGU indicates a coordinated campaign against the financial institution, with the bank also citing other individuals, including federal deputy Gustavo Gayer and lawyer Jeffrey Chiquini, as authors of these attacks. This action aims to combat misinformation targeting the stability of the national financial system.
