Americans know that banks have mistreated borrowers in many ways in foreclosure cases. Among other things, they habitually filed false court documents. There were investigations. We’ve been waiting for federal and state regulators to crack down.

Prepare for a disappointment. As early as this week, federal bank regulators and the nation’s big banks are expected to close a deal that is supposed to address and correct the scandalous abuses. If these agreements are anything like the draft agreement recently published by the American Banker — and we believe they will be — they will be a wrist slap, at best. At worst, they are an attempt to preclude other efforts to hold banks accountable. They are unlikely to ease the foreclosure crisis.

All homeowners will suffer as a result. Some 6.7 million homes have already been lost in the housing bust, and another 3.3 million will be lost through 2012. The plunge in home equity — $5.6 trillion so far — hits everyone because foreclosures are a drag on all house prices.

The deals grew out of last year’s investigation into robo-signing — when banks were found to have filed false documents in foreclosure cases. The report of the investigation has not been released, but we know that robo-signing was not an isolated problem. Many other abuses are well documented: late fees that are so high that borrowers can’t catch up on late payments; conflicts of interest that lead banks to favor foreclosures over loan modifications.
