The proposed financial reforms pending before Congress could cost Goldman Sachs nearly a quarter of its annual profits, Citigroup analysts estimate in a new report. Goldman Sachs could lose up to $5.06 in earnings on a per-share basis if Congress passes a bill that forbids banks from trading for their own profit, owning or sponsoring hedge funds and private equity funds, and compelling them to move most of their derivatives dealing into regulated markets, according to the research note. Combined with a potential fee to recoup taxpayer losses on TARP and higher deposit insurance assessments on its bank, Goldman could lose up to 23 percent of its profits, giving it the distinction of being the firm most impacted by the financial reform legislation. Morgan Stanley is a close second as the team of Citi analysts, led by Keith Horowitz, estimate that it could lose up to 20 percent of its profits. Up to 18 percent of JPMorgan Chase's profits are at risk, while Bank of America, the nation's largest bank by assets, could see up to 16 percent of its profits evaporate.
