Rarely has a public figure's reputation suffered a reversal as dramatic as Alan Greenspan's. When he left the Federal Reserve in early 2006 after nearly 19 years as chairman, he was hailed as the "maestro" and credited with steering the country through numerous economic shoals. Four years later, his policies are widely blamed for fostering the 2007-09 financial crisis. Now Greenspan is offering an elaborate "not guilty" defense.
The indictment of Greenspan is straightforward. Lax regulation by the Fed of financial markets encouraged dubious subprime mortgages. Easy credit engineered by the Fed further inflated the housing "bubble." Greenspan's rebuttal comes in a 14,000-word article for the Brookings Papers on Economic Activity, a journal from the think tank of the same name.
Greenspan is in part contrite. He admits to trusting private markets too much, as he had in previous congressional testimony. He concedes lapses in regulation. But mainly, he pleads innocent and makes three arguments.
First, the end of the Cold War inspired an economic euphoria that ultimately caused the housing boom. Capitalism had triumphed. China and other developing countries became major trading nations. From the fall of the Berlin Wall to 2005, the number of workers engaged in global trade rose by 500 million. Competition suppressed inflation. Interest rates around the world declined; as this occurred, housing prices rose in many countries (not just the United States) because borrowers could afford to pay more.
Second, the Fed's easy credit didn't cause the housing bubble because home prices are affected by long-term mortgage rates, not the short-term rates that the Fed influences. From early 2001 to June 2003, the Fed cut the overnight Fed funds rate from 6.5 percent to 1 percent. The idea was to prevent a brutal recession following the "tech bubble" -- a policy Greenspan still supports. The trouble arose when the Fed started raising the Fed funds rate in mid-2004 and mortgage rates didn't follow, as they usually did. What unexpectedly kept rates down, Greenspan says, were huge flows of foreign money, generated partially by trade surpluses, into U.S. bonds and mortgages.
Third, regulators aren't superhuman. They can't anticipate most crises and even miss some massive frauds when evidence is dumped in their laps: e.g., Bernie Madoff.
Up to a point, Greenspan's defense is convincing. The Fed was a prisoner of large forces it didn't completely understand or control; the anti-Greenspan backlash is political. But his explanation also misreads what happened.
It was not the end of the Cold War, as Greenspan asserts, that triggered the economic boom. It was the Fed's defeat of double-digit inflation in the early 1980s. Since the late 1960s, high inflation had destabilized the economy. Once it fell -- from 14 percent in 1980 to 3 percent in 1983 -- interest rates slowly dropped. This promoted economic expansion and boosted stocks and housing prices.
Similarly, China's economic liberalization began in 1978, well before the Cold War's end; India's liberalization was likewise largely independent of the Soviet Union's fate. What bolstered the global prestige of the "market model" was the renewed vigor of the American economy, which was a dividend of inflation's fall.
Greenspan's complicity in the financial crisis stemmed from succeeding too much, not doing too little. Recessions were infrequent and mild. The notion spread that the Fed could counteract almost any economic upset. Greenspan, once a critic of "fine-tuning" the business cycle, effectively became a convert.
"We had been lulled into a state of complacency," Greenspan writes in passing, failing to draw the full implication. Which is: Too much economic success creates the seeds of its undoing. Extended prosperity bred overconfidence that led to self-defeating behavior. Neither Greenspan nor any other major economist has yet wrestled with this contradiction.
