The Federal Reserve's recent action to encourage private equity investment in banks was a helpful step, but it didn't go far enough. That's according to John Douglas, who chairs the banking and financial institutions group at Paul, Hastings, Janofsky & Walker LLP. In this edition of Inside The Deal, Douglas tells Suzanne Stevens that the Fed needs to set forth the basis with which PE firms can take a controlling interest in banks. Douglas, who addressed the topic in an article for The Deal newsweekly, says the Fed is working on the issue, but it's been very slow in coming. In the meantime, there's a healthy appetite among PE firms to invest in struggling banks.
