"My reading of the evidence suggests that the role the conventional wisdom has attributed to oil price increases in the stagflation of the 1970s has been overstated," Bernanke said. The real problems, he said, stemmed from deeply rooted inflationary expectations at the time and the Fed's decision to tighten monetary policy in response to the surge in oil prices.
Today, analysts say the Fed has much more latitude -- and the markets know it. Inflation expectations are so low right now, sometimes bordering on worries about deflation, that most economists believe the Fed can cut rates without igniting inflationary fears.
"They have a lot of running room," said DiClemente.
At the same time, analysts think Greenspan has good reasons to be cautious. The biggest one is that the federal funds rate on overnight loans between banks is already at 1.25 percent, and monetary policy moves into uncharted territory if the rate drops to zero.
If the Fed were to lower rates next week, it would have less ammunition to stimulate the economy if a war with Iraq turned out to be more costly and protracted than expected. Greenspan has said the Fed can stimulate the economy even if overnight interest drops to zero, by buying Treasury securities. But the Fed has almost no experience with that approach.
