Financial Russian Roulette

By Paul Krugman

Will the U.S. financial system collapse today, or maybe over the next few days? I don’t think so — but I’m nowhere near certain. You see, Lehman Brothers, a major investment bank, is apparently about to go under. And nobody knows what will happen next.

To understand the problem, you need to know that the old world of banking, in which institutions housed in big marble buildings accepted deposits and lent the money out to long-term clients, has largely vanished, replaced by what is widely called the “shadow banking system.” Depository banks, the guys in the marble buildings, now play only a minor role in channeling funds from savers to borrowers; most of the business of finance is carried out through complex deals arranged by “nondepository” institutions, institutions like the late lamented Bear Stearns — and Lehman.

The new system was supposed to do a better job of spreading and reducing risk. But in the aftermath of the housing bust and the resulting mortgage crisis, it seems apparent that risk wasn’t so much reduced as hidden: all too many investors had no idea how exposed they were.

And as the unknown unknowns have turned into known unknowns, the system has been experiencing postmodern bank runs. These don’t look like the old-fashioned version: with few exceptions, we’re not talking about mobs of distraught depositors pounding on closed bank doors. Instead, we’re talking about frantic phone calls and mouse clicks, as financial players pull credit lines and try to unwind counterparty risk. But the economic effects — a freezing up of credit, a downward spiral in asset values — are the same as those of the great bank runs of the 1930s.

And here’s the thing: The defenses set up to prevent a return of those bank runs, mainly deposit insurance and access to credit lines with the Federal Reserve, only protect the guys in the marble buildings, who aren’t at the heart of the current crisis. That creates the real possibility that 2008 could be 1931 revisited.

But Henry Paulson, the Treasury secretary, was adamant that he wouldn’t sweeten the deal by putting more public funds on the line. Many people thought he was bluffing. I was all ready to start today’s column, “When life hands you Lehman, make Lehman aid.” But there was no aid, and apparently no deal. Mr. Paulson seems to be betting that the financial system — bolstered, it must be said, by those special credit lines — can handle the shock of a Lehman failure. We’ll find out soon whether he was brave or foolish.
