5 Disastrous Decisions That Got Us into This Economic Mess
Continued from previous page
Here too Greenspan played a role. When I was chairman of the Council of Economic Advisers, during the Clinton administration, I served on a committee of all the major federal financial regulators, a group that included Greenspan and Treasury Secretary Robert Rubin. Even then, it was clear that derivatives posed a danger. We didn't put it as memorably as Warren Buffett -- who saw derivatives as "financial weapons of mass destruction" -- but we took his point. And yet, for all the risk, the deregulators in charge of the financial system -- at the Fed, at the Securities and Exchange Commission, and elsewhere -- decided to do nothing, worried that any action might interfere with "innovation" in the financial system. But innovation, like "change," has no inherent value. It can be bad (the "liar" loans are a good example) as well as good.
No. 2: Tearing Down the Walls
The deregulation philosophy would pay unwelcome dividends for years to come. In November 1999, Congress repealed the Glass-Steagall Act -- the culmination of a $300 million lobbying effort by the banking and financial-services industries, and spearheaded in Congress by Senator Phil Gramm. Glass-Steagall had long separated commercial banks (which lend money) and investment banks (which organize the sale of bonds and equities); it had been enacted in the aftermath of the Great Depression and was meant to curb the excesses of that era, including grave conflicts of interest. For instance, without separation, if a company whose shares had been issued by an investment bank, with its strong endorsement, got into trouble, wouldn't its commercial arm, if it had one, feel pressure to lend it money, perhaps unwisely? An ensuing spiral of bad judgment is not hard to foresee. I had opposed repeal of Glass-Steagall. The proponents said, in effect, Trust us: we will create Chinese walls to make sure that the problems of the past do not recur. As an economist, I certainly possessed a healthy degree of trust, trust in the power of economic incentives to bend human behavior toward self-interest -- toward short-term self-interest, at any rate, rather than Tocqueville's "self interest rightly understood."
The most important consequence of the repeal of Glass-Steagall was indirect -- it lay in the way repeal changed an entire culture. Commercial banks are not supposed to be high-risk ventures; they are supposed to manage other people's money very conservatively. It is with this understanding that the government agrees to pick up the tab should they fail. Investment banks, on the other hand, have traditionally managed rich people's money -- people who can take bigger risks in order to get bigger returns. When repeal of Glass-Steagall brought investment and commercial banks together, the investment-bank culture came out on top. There was a demand for the kind of high returns that could be obtained only through high leverage and big risktaking.
There were other important steps down the deregulatory path. One was the decision in April 2004 by the Securities and Exchange Commission, at a meeting attended by virtually no one and largely overlooked at the time, to allow big investment banks to increase their debt-to-capital ratio (from 12:1 to 30:1, or higher) so that they could buy more mortgage-backed securities, inflating the housing bubble in the process. In agreeing to this measure, the S.E.C. argued for the virtues of self-regulation: the peculiar notion that banks can effectively police themselves. Self-regulation is preposterous, as even Alan Greenspan now concedes, and as a practical matter it can't, in any case, identify systemic risks -- the kinds of risks that arise when, for instance, the models used by each of the banks to manage their portfolios tell all the banks to sell some security all at once.
