Delay is not innocuous. When a bank’s insolvency is ignored, the incentives for normal prudent banking collapse. Management has nothing to lose. It may take big new risks, in volatile markets like commodities, in the hope of salvation before the regulators close in. Or it may loot the institution—nomenklatura privatization, as the Russians would say—through unjustified bonuses, dividends, and options. It will never fully disclose the extent of insolvency on its own.
The most likely scenario, should the Geithner plan go through, is a combination of looting, fraud, and a renewed speculation in volatile commodity markets such as oil.
