Greenspan says Congress needs to give the government new powers to handle troubled companies to minimize any potential losses to American taxpayers. A self-described libertarian Republican, Greenspan has a reputation for being wary of giving the government extra powers. However, in crisis situations, there needs to be a clear process for handling bailouts, rather than depending on the Fed to do so, he reckons.

A high-level panel of financial officials should be given broad authority to quickly determine whether a failing company poses a sufficient threat to the entire U.S. economy, he recommends. If so, the company would be shut down.

“We need laws that specify and limit the conditions for bailouts – laws that authorize the Treasury to use taxpayer money to counter systemic financial breakdowns transparently and directly rather than circuitously through the central bank as was done during the blowup of Bear Stearns,” Greenspan wrote in a new epilogue to the paperback edition of his memoir, “The Age of Turbulence: Adventures in a New World.” (The paperback will be released Tuesday; the hardcover came out last year.)

Greenspan envisions the formation of a group akin to the Resolution Trust Corp. to step in, take a troubled company into conservatorship, wipe out the equity, impose some charge or “haircut” on its debts before guaranteeing them and then selling its assets.

The RTC was created in 1989 to deal with the aftermath of the savings and loan crisis. It disposed of the assets of failed savings and loans and then went out of business.

Costs to taxpayers would still be a concern, he acknowledges. As with the RTC, however, the public cost could be minimized, he says.

Critics in Congress, in academia and elsewhere worry that the Fed’s unprecedented actions – including financial backing in March for JPMorgan Chase & Co.’s takeover of Bear Stearns Cos. – are putting taxpayers on the hook for billions of dollars of potential losses. They also say it encourages “moral hazard,” that is, allowing financial companies to gamble more recklessly in the future.
