I rely on many sources -- more than I can count -- for information about what is going on in the financial world. Barron's in one of them. I have been a regular reader of the weekly magazine (and an online subscriber) for years. One feature I always look forward to are the interviews with (genuine) experts and old hands. This week's issue features a Q&A with Nouriel Roubini, an individual who has consistently been ahead of the curve throughout the unfolding crisis (as I've noted many times at Financial Armageddon). Barron's Robin Goldwyn Blumenthal is the questioner in "Yes, That's $2 Trillion of Debt-Related Losses."

LIKE THE EXHORTATIONS OF JEREMIAH TO THE NATION OF Israel before the first temple's destruction, the warnings of economist Nouriel Roubini fell on deaf ears. For the past two years Roubini, a professor at New York University, has cautioned about a huge housing bubble whose bursting would lead to a 20% drop in home prices; a collapse in subprime mortgages; a severe banking crisis and credit crunch; the near-failure of Fannie Mae and Freddie Mac , and a U.S. recession of a magnitude not seen since the Great Depression. So far, this latter-day prophet of doom has been on the mark, though time will tell about the recession part.

A Turkish native who grew up in Italy, Roubini trained at Harvard and later advised the Clinton White House, after his blog on the Asian financial crisis attracted the attention of Washington's economic and political elite. Roubini still publishes the blog -- the RGE Monitor -- and teaches economics at NYU's Stern School of Business. We caught up with him recently at his offices in lower Manhattan, and continued the conversation at Barron's. For his latest predictions, please read on.

Barron's: Unfortunately for the rest of us, you have a pretty good track record. How much more misery lies ahead?

Roubini: We are in the second inning of a severe, protracted recession, which started in the first quarter of this year and is going to last at least 18 months, through the middle of next year. A systemic banking crisis will go on for awhile, with hundreds of banks going belly up.

Which banks, specifically, will fail?

I don't want to name names, but many, given the housing bust, will become insolvent. Their losses are mounting because they have written down only their subprime loans so far. They haven't started writing down most of their consumer-credit losses, and reserves for losses are much less than they should have been. The banks are playing all sorts of accounting gimmicks not to recognize them. There are hundreds of millions of dollars outstanding in home-equity loans that eventually could be worth zero, too.

So far, we have seen no recession in the technical sense: two consecutive quarters of negative growth in real GDP. Why not?

The definition of a recession isn't only two consecutive quarters of negative growth. The NBER (National Bureau of Economic Research) puts a lot of emphasis on things like employment, and employment has already fallen for seven months in a row. It also emphasizes income and retail and wholesale sales. Many of these things are declining.

Maybe the recession started in January; if you look at the data on gross domestic product on a monthly basis between February and April, GDP was falling. Saying this is not a recession is just a joke. Maybe instead of a 'U' recession and recovery, it will be a 'W,' with a rebound in the second quarter. But by the third quarter, the effect of the government's tax rebates is totally gone, because other forces on the consumer are more persistent and negative.

Which forces, for instance?

The U.S. consumer is shopped out and saving less. Debt to disposable income has risen to 140% from 100% in 2000. Hit by falling home prices, the consumer no longer can use his house as an ATM machine. The stock market is falling and (issuance of) home-equity loans (has) collapsed.
