Quote from DrChaos:
What is not Greenspan's fault:
1% interest rates. There were significant deflationary forces, and low rates (short term) were a good idea.
China's peg of USD to the Yuan and Japan's soft peg (to compete) resulting in massive dollar reserve increases and economically irrational low long-term rates, resulting in housing bubble.
What was Greenspan's fault:
Failing to use more specific tools to prick outrageous asset bubbles than basic interest rates. The Fed ought to be more than just the short-term rate-setting FOMC.
Specifically: failure to seriously increase the margin requirement on stocks during the bubble. The argument that hedgies etc had other means of borrowing doesn't stand up---the increase in margin would ripple through the whole banking and financing.
The second one is the Fed's failure to crack down on underwriting standards for mortgage loans recently, especially in bubble areas. If everything had been 20% down 30 year fixed with sane debt to income ratios there wouldn't be a bubble and the upcoming recession/depression.
The world and finance industry is not only about interest rates and it will really suck when normal people who didn't do anything foolish get screwed and lose their jobs in the upcoming big recession.
deflation? everyone is paying more for goods yet cpi numbers were limp. there wasn't any need to drop rates by a ton.
greenspans answer to everything was to pump money into the economy. it was the wrong answer and keeps getting worse
