BNP Paribas SA’s $9 billion settlement with U.S. authorities, aided by internal whistleblowers, has spurred calls for federal banking regulators to protect and reward individuals who report wrongdoing by banks. The U.S. Securities and Exchange Commission has scored big enforcement successes and delivered millions of dollars in awards to whistleblowers under a program from the 2010 Dodd-Frank overhaul of Wall Street. The Commodity Futures Trading Commission, as well as the SEC, will provide whistleblowers with a share of fines collected.
