WASHINGTON - Janet Yellen has won credit for guiding the Federal Reserve's first six months of transition from the Ben Bernanke era.
Some Federal Reserve officials think the U.S. economy is improving fast enough that the Fed will need to act sooner than previously thought to slow the extraordinary support it's been providing through ultra-low interest rates.
Minutes of the Fed's discussion at its July 29-30 meeting released Wednesday show that some officials thought the Fed would need "to call for a relatively prompt move" to reduce the stimulus it has supplied since the financial crisis erupted in 2008. Otherwise, these officials felt the Fed risked overshooting its targets for unemployment and inflation.
In the end, the Fed made no changes at the July meeting. It approved, 9-1, keeping its current stance on interest rates.
Still, the minutes revealed a sharp and perhaps intensifying debate within the Fed about how and when to scale back its help for a steadily improving economy.
Bernanke's Fed had steered the economy through a deep crisis by slashing interest rates and restoring confidence in banks. Yellen has so far carried on his approach with barely a hiccup.
She may one day recall her first six months as a too-brief honeymoon.
The perilous question that now awaits Yellen's Fed has put investors on nervous alert: Can it manage to raise rates from record lows without weakening the U.S. economy or spooking markets?
Or, conversely, will it wait too long to raise rates, causing the economy to overheat and inflation to surge?
No one knows. Which helps explain the anticipation surrounding Yellen's speech Friday at the economic conference sponsored every August in Jackson Hole, Wyo., by the Federal Reserve Bank of Kansas City. Given that this year's topic is labor markets, Yellen is sure to spell out her latest assessment of the U.S. job market.
Whatever she says - or, perhaps, doesn't say - will shape perceptions of when and how aggressively the Fed will raise rates.
Yellen has frequently characterized the job market as weaker than the unemployment rate suggests. She's noted, for example, that the jobless rate, now a nearly normal 6.2 percent, belies other unhealthy trends: Weak pay growth, a sizable number of part-timers who want full-time work and high proportions of people who've been looking for a job for more than six months or have stopped looking.
Might Yellen describe those trends as chronic problems with no end in sight? Or as likely temporary drags on the job market, destined to fade as the economy further improves? Investors will seek any sign of a coming rate hike because it would mean higher rates on business and consumer loans and could hurt stock prices.
At Jackson Hole, Bernanke would sometimes use his speeches to telegraph actions the Fed was considering. Yellen could take the opportunity to shed light on the Fed's plans for withdrawing the extraordinary economic support it's provided since 2008.
"The road ahead will get much tougher for Yellen when she starts outlining the Fed's exit strategy," said David Jones, chief economist at DMJ Advisors and the author of a book on the Fed's first century. "Any change could be accompanied by significant market instability."
This year, the Fed has been paring its monthly bond purchases, which have been intended to keep long-term rates low. Yellen has stressed that even after the bond purchases end this fall, the Fed will keep rates low and maintain its vast investment portfolio to keep downward pressure on rates.
The impending end of the purchases - a step investors once anticipated with dread - is now being taken in stride. The market has remained calm, and stocks are up this year, suggesting that Yellen's reassurances have had an effect.
That said, her first six months haven't been without stumbles. Consider her first news conference. Responding to a question, Yellen said that when the Fed stated it would keep its benchmark rate ultra-low for a "considerable time" after its bond purchases end, that phrase meant around six months.
Stocks sank on fears that rate increases could start sooner than expected.
Asked about her six-month comment at her next news conference, Yellen de-coupled the phrase "considerable time" from any specific period.
"It depends on how the economy progresses," she explained.
Diane Swonk, chief economist at Mesirow Financial, said Yellen was trying to be clear without perhaps recognizing how much a Fed chair's words can be overinterpreted.
"Yellen is a much clearer speaker than past Fed chairmen," Swonk said. "But Yellen learned the dangers from being too clear. She will never use the words 'six months' again."
Yellen has appeared comfortable fielding reporters' questions. She's also withstood grilling from members of Congress. Where Bernanke's voice would sometimes quaver under hostile questioning, Yellen has remained cool and has parried any attacks in a calm voice that hints of her native Brooklyn.
"It would be a grave mistake for the Fed to commit to conduct monetary policy according to a mathematical rule," Yellen explained to the House Financial Services Committee after some Republicans pressed her to back legislation to compel the Fed to follow a policy rule in setting rates.
Expressing the frustration that some Republicans say they feel about expanded Fed influence over the economy, the committee chair, Jeb Hensarling, R-Texas, told Yellen that "a dramatic increase in power calls for a corresponding increase in accountability and transparency."
Yellen has stressed that the unorthodox steps the Fed took to fight the recession were needed to put people back to work. She has sought to reverse any perception that the Fed distributed billions to prop up big banks during the financial crisis while doing little to help people who had lost jobs.
"Our goal is to help Main Street, not Wall Street," she declared in her first speech as chair. She spoke of "shattered lives and families" from high unemployment and said the Fed would keep working until the job market was healthy.
Despite months of solid hiring and declining unemployment, Yellen contends that too many people have been out of work for too long, that too many are stuck in part-time jobs and that pay growth is still anemic.
Challenging that view, though, are some Fed officials who sound more concerned about inflation. They argue that the Fed risks igniting inflation by waiting too long to raise rates.
Many analysts think Yellen will use Friday's speech to explain her continued support for low rates.
