Why Yellen Should Be Next Fed Chief: Former Fed Official
Vice-chair of the Federal Reserve Janet Yellen is by far the most credible successor to central bank chief Ben Bernanke, former Fed Governor Robert Heller told CNBC on Wednesday.
Heller's call comes amid talk that Bernanke could leave his post at the end of his term in January after U.S. President Barack Obama hinted at the Fed chief's departure in a television interview on Monday.
"Janet Yellen has the best resume for the job, bar none," Heller told CNBC Asia's "Squawk Box."
"She has been a Fed insider for a long time... She has earned the job and is well qualified and Obama is also under pressure to nominate more women, so he would have to tell his own constituency that Janet wasn't qualified and she is," he added.

Yellen, aged 66, has been Fed vice chair since 2010 and is viewed as a strong contender to be the next head of the U.S. central bank.
A Reuters poll on June 12 found that an overwhelming majority of economists predicted she would get the job.
Other contenders include Harvard economist Lawrence Summers, Timothy Geithner, Obama's first-term Treasury secretary, Roger Ferguson, chief executive officer of TIAA-CREF, which manages retirement funds for many U.S. schools and hospitals, and retired Fed vice-chairman Donald Kohn.

Heller said that if Yellen, who is known for her dovish stance on monetary policy, becomes Fed chief she could surprise markets with some bold initial moves.
"There is that irony that if someone is known as a dove, they first have to show that they are tough. So one would expect some of her early actions would be to surprise people on the hawkish side just to show she is macho," he added.
When to Unwind QE?
Fears over the Fed moving to taper its $85 billion a month quantitative easing program has sent shock waves through financial markets in recent weeks.

A two-day Fed meeting ends later on Wednesday and is hotly anticipated as markets try to assess the Fed's next move.
Heller said he expected the Fed to start unwinding its monetary stimulus in December.
"I think tapering will start in December or a bit earlier, the economy is doing reasonably well, muddling through with 2 percent growth. The Fed has leeway to start tapering off, if it were me I would start tapering right away," said Heller.
He said that the biggest risk regarding the end of quantitative easing was not ending the program.
"The biggest risk is continuing down this road and saying just a little bit more and all will be well. All will not be well," said Heller.
"We are building up enormous Federal debts and the Federal Reserve is buying up the entire Fed deficit and it's being added to the enormous debt load that the country is under… that is a road to a disaster in the long run," he added.
