I don't know why it took so long for economists to admit the current housing and credit mess will impact the economy, but the latest report from the National Association for Business Economists (NABE) expects GDP to expand just 1.5% from October through December. That's less than half the 3.9% we saw in the period of July through September.
Historically, a housing slowdown always becomes a drag on the economy, as people spend less on things related to buying or fixing up a new house. On top of a real estate slowdown we also have a credit mess that's essentially frozen much of the type of lending that fueled the housing bubble that just burst. People can no longer use their homes as piggy banks that can be tapped for whatever they want to buy.
For all of this year economists expected the economy to grow by 2.1%. That would be the weakest economic growth since 2002 when the economy grew by just 1.6% as we headed out of our last recession. NABE also lowered its growth prediction for next year to 2.5% from 2.8%, and that may even be too optimistic unless something is done to get the housing market back on track. As long as foreclosures keep rising and people are unable to sell their homes or refinance unaffordable mortgages, you won't see a turnaround in this economy.
