In late 1999, Congress enacted financial modernisation legislation that dramatically deregulated the financial services industry and expanded the powers of financial institutions in the USA. In keeping with this deregulation and expanded powers, the regulatory landscape and enforcement mechanisms also changed. While many applaud this legislation, others point to previous US experience where financial deregulation overwhelmed federal regulators and resulted in massive failures of financial institutions and, consequently, in huge federal bailouts. The authors examine here the prospect of supplementing regulation with certain forms of private intervention. Specifically, they address the question: is there a role for whistleblowing and bounty hunting as means of supplementing existing regulation in the financial services industry?
