The NY Times today has an excellent article that starts: Ben Bernanke, meet Gary Crittenden. While you're easing credit, he is tightening it." In two brief sentences the writer (Floyd Norris) speaks volumes: Gary Crittenden is Citigroup's CFO, who just told analysts the largest bank in the US is reducing consumer lending and raising interest rates. Asked whether credit card lending was an area where Citi might want to “pull back or increase pricing,” he responded, “All of the above.” Mortgage lending is also being cut.That's what a credit crunch looks like, in the ground: lenders working to repair damaged balance sheets end up throwing monkey wrenches into the Fed's "printing press". And that's also how economies slide to the bottom of a liquidity trap, staring in frustration at a useless ZIRP .
