Innovating Our Way to Financial Crisis

Today's Paul Krugman column is a must-read. Here's a tease:

Credit — lending between market players — is to the financial markets what motor oil is to car engines. The ability to raise cash on short notice, which is what people mean when they talk about “liquidity,” is an essential lubricant for the markets, and for the economy as a whole.

But liquidity has been drying up. Some credit markets have effectively closed up shop. Interest rates in other markets — like the London market, in which banks lend to each other — have risen even as interest rates on U.S. government debt, which is still considered safe, have plunged.

“What we are witnessing,” says Bill Gross of the bond manager Pimco, “is essentially the breakdown of our modern-day banking system, a complex of leveraged lending so hard to understand that Federal Reserve Chairman Ben Bernanke required a face-to-face refresher course from hedge fund managers in mid-August.”

The freezing up of the financial markets will, if it goes on much longer, lead to a severe reduction in overall lending, causing business investment to go the way of home construction — and that will mean a recession, possibly a nasty one.
