(Bloomberg News) Ben S. Bernanke warned last month that payroll gains might slow as companies adjust their labor needs for a period of moderate growth. Today's Labor Department report may have proved the Federal Reserve chairman right.

Employers in the U.S. added 120,000 jobs in March, the fewest in five months. The unemployment rate fell to 8.2 percent from 8.3 percent the month before as people stopped looking for work. The March report followed the best six-month streak of job growth since 2006.

"Chairman Bernanke should be putting out the world's biggest 'I told you so,'" said Phillip Swagel, an economist at the University of Maryland and former assistant Treasury secretary in George W. Bush's administration. "It must give the Fed some comfort that they continue to have this accommodative stance."

Today's report probably won't trigger a decision to buy more assets when Fed policy makers next meet April 24-25, nor will it alter their commitment to keep the benchmark lending rate around zero until late 2014, said John Silvia, chief economist at Wells Fargo Securities LLC in Charlotte, North Carolina.

At the same time, he said, disappointing labor reports in April and May could help build a case for further easing at the June meeting of the Federal Open Market Committee, headed by Bernanke.

"When you look at employment per se, it's not up to the level he wants to see," Silvia said. "It's very difficult for the Fed to say 8.2 percent, that's good enough."

More insight into the Fed's response to the data will come next week when policy makers discuss the economic outlook. Vice Chairman Janet Yellen will speak in New York on April 11, and William C. Dudley, president of the Federal Reserve Bank of New York, will speak in Syracuse the next day. Bernanke is scheduled to discuss financial stability on April 9.

In a speech on March 26, Bernanke said recent strong job gains may be a "reversal of the unusually large layoffs that occurred during late 2008 and over 2009." If that is the case, he said, then "significant improvements in the unemployment rate will likely require a more-rapid expansion of production and demand from consumers and businesses, a process that can be supported by continued accommodative policies."

Today's jobs report showed scant improvement in some of the trends that the Fed chairman said he finds most worrisome. The share of the unemployed who have been out of work for 27 weeks or more was little changed at 42.5 percent in March. Average weekly earnings fell, and the average work week decreased to 34.5 hours from 34.6.

Last month, and in several speeches and testimony before that, the Great Depression scholar has made it clear that long- term unemployment threatens to erode workers' skills and eventually detach them from the labor force, ultimately reducing how fast the U.S. economy can grow. Bernanke has never embraced that as an acceptable outcome, or one that the Fed can do nothing about. He also hasn't taken the view that long-term unemployment is fully explained by a mismatch of worker skills with employers' needs.
