Greenspan Concedes Error on Regulation
WASHINGTON — For years, a Congressional hearing with Alan Greenspan was a marquee event. Lawmakers doted on him as an economic sage. Markets jumped up or down depending on what he said. Politicians in both parties wanted the maestro on their side.
Greenspan Prepared RemarksBut on Thursday, almost three years after stepping down as chairman of the Federal Reserve, a humbled Mr. Greenspan admitted that he had put too much faith in the self-correcting power of free markets and had failed to anticipate the self-destructive power of wanton mortgage lending.
“Those of us who have looked to the self-interest of lending institutions to protect shareholders’ equity, myself included, are in a state of shocked disbelief,” he told the House Committee on Oversight and Government Reform.
..............“You had the authority to prevent irresponsible lending practices that led to the subprime mortgage crisis. You were advised to do so by many others,” said Representative Henry A. Waxman of California, chairman of the committee. “Do you feel that your ideology pushed you to make decisions that you wish you had not made?”
Mr. Greenspan conceded: “Yes, I’ve found a flaw. I don’t know how significant or permanent it is. But I’ve been very distressed by that fact.”
On a day that brought more bad news about rising home foreclosures and slumping employment, Mr. Greenspan refused to accept blame for the crisis but acknowledged that his belief in deregulation had been shaken.
He noted that the immense and largely unregulated business of spreading financial risk widely, through the use of exotic financial instruments called derivatives, had gotten out of control and had added to the havoc of today’s crisis. As far back as 1994, Mr. Greenspan staunchly and successfully opposed tougher regulation on derivatives.
................Many Republican lawmakers on the oversight committee tried to blame the mortgage meltdown on the unchecked growth of Fannie Mae and Freddie Mac, the giant government-sponsored mortgage-finance companies that were placed in a government conservatorship last month. Republicans have argued that Democratic lawmakers blocked measures to reform the companies.
But Mr. Greenspan, who was first appointed by President Ronald Reagan, placed far more blame on the Wall Street companies that bundled subprime mortgages into pools and sold them as mortgage-backed securities. Global demand for the securities was so high, he said, that Wall Street companies pressured lenders to lower their standards and produce more “paper.”
