Some argue government should do more to stop a negative feedback loop in the housing market.
America's economy confronts a vicious cycle of falling home prices and rising foreclosures, and the challenge for policymakers is how – and how much – to intervene.
Top economic officials are already taking some steps that are aimed, at least in part, at slowing the erosion of home prices. The Treasury has been prodding banks to rewrite the terms of loans rather than foreclose on mortgage holders who are in default.
One goal is to help ordinary Americans keep their homes and to keep neighborhoods from deteriorating.
Another rationale is to bolster an industry at the heart of the economy: the banking system on which consumers and businesses depend. When homes go into foreclosure, banks face a pileup of bad assets on their books. Already, that has caused banks to start tightening the spigot on new lending.
But even as US officials look for ways to help avert a deeper credit crunch, they face political and financial limits on how much the government can do to prop up the real estate market after a historic price run-up.
"We're entering an unprecedented period," says Richard Bitner, a former lender in subprime mortgages and author of a book on the industry. "I'm a believer that markets have a tendency to work their way through these things…. My great concern is that Congress is going to go too far."
Falling prices are a drag on borrowing
But "do nothing" doesn't look like an appealing option right now, either.
The problems in housing are part of a broader collapse of confidence among lenders and borrowers – a problem that makes it hard for markets to find an easy path back toward health and balance. An economy teetering on the edge of a recession makes the challenges more acute.
From student loans to corporate buyouts, investor dealings in various forms of debt have been freezing up, as the players reassess the value and risks involved.
Housing remains a central piece of this credit puzzle, because so many Americans buy homes and so many financial firms underwrite mortgages. With home prices falling, many borrowers and lenders are sitting on the sidelines.
