President Barack Obama said his nominee for Federal Reserve chairman will be someone who embraces the central bank’s dual mandate to promote price stability and maximum employment, and he has narrowed his choice “to some extraordinarily qualified candidates.”

“You can anticipate that over the next several months, an announcement will be made,” Obama said in an interview with the New York Times on July 24, according to a transcript published Sunday on the newspaper’s Website. Obama said he hasn’t made a final decision.

Obama isn’t expected to nominate a successor to the current chairman, Ben S. Bernanke, until at least September, an administration official said Saturday.

Bernanke, whose second four-year term ends on Jan. 31, hasn’t indicated whether he would seek or accept a third term. Last month, Obama said the Fed chairman has stayed in the post “longer than he wanted.”

Obama declined to say who the finalists are, amid speculation that former Treasury Secretary Lawrence Summers and Fed Vice Chairman Janet Yellen are leading candidates.

Treasury Secretary Jacob J. Lew said Summers and Yellen are “both extraordinarily talented people” and that he has “great admiration for both of them,” while declining to comment on whether Obama may nominate either of them to lead the Fed.

Oval Office

“We will keep those discussions to the privacy of the Oval Office,” Lew said on CNN’s “State of the Union” in an interview airing Sunday.

In the interview at Knox College in Galesburg, Illinois, Obama said he wants a chairman who understands the Fed’s dual mandate to promote maximum employment and price stability.

“And when unemployment is still too high, and long-term unemployment is still too high, and there’s still weak demand in a lot of industries, I want a Fed chairman that can step back and look at that objectively and say, let’s make sure that we’re growing the economy, but let’s also keep an eye on inflation,” Obama said.

“If the markets start frothing up, let’s make sure we’re not creating new bubbles,” he said.

About a third of the 54-member Senate Democratic caucus sent a letter July 25 encouraging Obama to nominate Yellen.

Senator Dianne Feinstein, a Democrat from California, praised Yellen Sunday on the CNN program “State of the Union,” saying she is “well thought of. She knows the Fed. And she is very highly qualified.”

Qualified Woman

The administration would benefit from appointing a qualified woman to the job, Feinstein said. Yellen has been “close to Bernanke,” and “Bernanke has done a very good job,” she said.

Obama also discussed the Keystone XL pipeline project, disputing Republican claims it would be a job creator. The project that would connect oil production from Alberta to refineries on the U.S. Gulf Coast would initially create 2,000 jobs during the construction phase that would take a year or two, Obama said.

“And then after that, we’re talking about somewhere between 50 and 100 jobs in an economy of 150 million working people,” he said.

The pipeline may benefit the U.S. by integrating energy supplies with Canada, Obama said. He added that he plans to make his decision based on whether the project would significantly contribute to carbon levels in the atmosphere. Canada could be doing more to mitigate carbon release, he said.

Denied Permit

Obama in January 2012 denied a permit for Keystone because of concerns over harming the ecologically sensitive Sand Hills region in Nebraska. TransCanada Corp. resubmitted a plan, with a new route from the Canadian border to connect to a pipeline in Steele City, Nebraska.

The State Department has jurisdiction over the fate of the $5.3 billion project that would carry heavy crude called bitumen from Alberta to refineries along the U.S. Gulf Coast because the pipeline crosses the U.S. border with Canada.

The Calgary-based company’s proposal is supported by labor unions and the energy industry and opposed by environmental groups fighting climate change.

Obama last month said State Department shouldn’t approve the pipeline unless the agency is confident the pipeline won’t increase net greenhouse gas emissions.

In the interview, Obama also said he plans to be part of the 50th anniversary of the March on Washington by civil rights activists in 1963 when Martin Luther King gave his famous “I Have a Dream” speech. A march has been organized Aug. 28 to commemorate the original convergence on the capital.

“Obviously, after the Trayvon Martin Case, a lot of people have been thinking about race, but I always remind people -- and, in fact, I have a copy of the original program in my office, framed -- that that was a march for jobs and justice; that there was a massive economic component to that,” Obama said.
