Congressional investigators yesterday demanded that the nation's nine largest banks prove they are not using an emergency infusion of $125 billion in taxpayer funds to lavish their executives with wealthy bonuses. I question the appropriateness of depleting the capital that taxpayers just injected into the banks through the payment of billions of dollars in bonuses, especially after one of the financial industry's worst years on record," [Rep. Henry A. Waxman (D-Calif.), chairman of the House Committee on Oversight and Government Reform,] wrote in a letter to the banks. Lawmakers across the political spectrum want to ensure that the government's bailout program results in increased lending, not bigger paydays for executives. But a new study suggests that financiers are still bullish about their bonuses. More than two-thirds of Wall Street professionals are expecting a bonus this year, and 36 percent are anticipating a larger bonus than last year, according to a survey by eFinancialCareers, a career networking company. "Some experts have suggested that a significant percentage of this compensation could come in year-end bonuses and that the size of the bonuses will be significantly enhanced as a result of the infusion of taxpayer funds," Waxman said. In his letter to the banks, Waxman asked them to provide detailed data on compensation packages since 2006, as well as the projected salaries and bonuses for the rest of the year. The request was sent to Bank of America, Bank of New York Mellon, Citigroup, Goldman Sachs, J.P. Morgan Chase, Merrill Lynch, Morgan Stanley, State Street, and Wells Fargo.
