Brazil's Audit Court chief just made a significant statement: the Supreme Court is the only body with authority to overturn a central bank decision. This effectively closes the door on earlier calls to reverse the monetary authority's ruling on the liquidation of Banco Master. The move underscores a crucial separation of powers in Brazil's financial system. The central bank's decision to wind down the troubled bank now stands firm, barring Supreme Court intervention. This development highlights how monetary policy decisions can face legal challenges yet remain insulated from certain institutional pressures—a dynamic that shapes confidence in financial systems globally.
