Ben Bernanke launches blog defending actions as Fed chief

Ben Bernanke no longer leads the Federal Reserve, but he's hardly letting up in his defence of the ultra-low-rate policies he engineered and his successor, Janet Yellen, has continued.

In his first post as a new blogger Monday, Bernanke struck back at critics who he said had charged the Bernanke Fed with, among other things, "throwing seniors under the bus" by keeping rates too low for too long.

He also disputed accusations that the Fed is still distorting financial markets and investment decisions by keeping rates "artificially low."

Both criticisms, Bernanke wrote in "Ben Bernanke's Blog," reflect a misunderstanding of economic reality.

New phase

His 1,200-word post gave Bernanke a platform to continue the efforts he began as Fed chairman to justify the low-rate policies the Fed pursued under his leadership. The Fed cut its key short-term rate to a record low near zero in 2008 and has kept it there since. Supporters say those rates have helped rejuvenate the economy. Critics counter that they have raised the risk of high inflation and are distorting financial markets.

After eight years as chairman, Bernanke stepped down from the Fed early last year and became a senior fellow at the Brookings Institution in Washington. He has spent the past year writing a book on his time at the Fed and giving speeches.

In his blog post, he argued that raising short-term rates during a time of weak growth and high unemployment just to give retirees a higher yield on savings accounts would "have been exactly the wrong thing to do."

Doing so, he said, would likely have further slowed the economy. And he said it probably would have forced the Fed to reverse course and resume cutting rates to respond to the weaker growth.

"This is hardly a hypothetical scenario," Bernanke wrote. "In recent years, several major central banks have prematurely raised interest rates, only to be forced by a worsening economy to backpedal and retract the increases."

It would have been wiser for those foreign central banks to keep rates low to encourage borrowing and spending and strengthen their economies. This would have allowed those nations to more quickly approach what economists call an "equilibrium rate" an interest rate consistent with healthy levels of employment and investment.

More to come

Bernanke said that in future blog posts, he would discuss what characteristics of the economy contribute most to the economy's low-rate environment an environment that, he noted, exists overseas as well as in the United States.

He said he was enjoying the freedom to express his thoughts without having to fear that he might jolt financial markets. He recalled that his predecessor as Fed chairman, Alan Greenspan, once told a Senate committee that he had learned as a central banker "to mumble with great incoherence."

"Now that I'm a civilian again," Bernanke wrote, "I can once more comment on economic and financial issues without my words being put under the microscope by Fed watchers."

In announcing Bernanke's role as a blogger, Brookings said the former Fed chairman, who is an avid baseball fan, might occasionally touch on the sport in his postings.

Bernanke's book, which will cover the causes and government responses to the 2008 financial crisis, is scheduled to be published this fall by W.W. Norton.
