Having its founder, chief executive officer, and chairman behind bars has pushed BTG Pactual to the brink of insolvency as clients pull their money out. Within days of his arrest, Esteves had relinquished his controlling stake in the firm, and his partners had begun a wholesale selloff of assets. To avert disaster, Brazil’s central bank helped engineer a $1.6 billion rescue line from the country’s privately funded deposit guarantee fund. Still, the bank’s shares have lost half their value since Esteves’s arrest. On Dec. 7, prosecutors formally accused the banker of obstruction of justice. Antônio Carlos de Almeida Castro, Esteves’s lawyer, says his client has done nothing wrong.The metastatic graft scandal that sent Esteves to jail threatens more than the survival of BTG. So many legislators are implicated, Congress has been unable to pass legislation to contain an exploding budget deficit. President Dilma Rousseff has grown so unpopular that lawmakers are maneuvering to impeach her for allegedly cooking the government’s books. Meanwhile, the economy is sliding into what Goldman Sachs calls a full-blown depression.
