The employment cost index, along with the monthly Job Openings and Labor Turnover Survey, is thought to be one of Fed Chair Janet Yellen's favorite measures of slack in the labor market. Yellen and her central bank cohorts have said they are convinced that inflation is moving toward their 2 percent goal, but hitting that level on a sustained basis has proved troublesome for the slow-moving economy.
The news came as the Fed began its regularly scheduled two-day meeting Tuesday. The policymaking Federal Open Market Committee is not expected to approve a rate increase at the meeting, but it could tip its hand about how current developments will impact its future actions.
Since President Donald Trump's election victory in November, expectations on Wall Street have increased that the economy could grow at a more rapid pace than the current 1.6 percent post-recession rate. That's due to Trump's promise to cut taxes and regulations and increase domestic spending on infrastructure.
"Wage growth in the aggregate remains only decent," Peter Boockvar, chief market analyst at The Lindsey Group, said in a note. "We continue to wait for the wage/salary acceleration and the hope is that it comes when friendlier fiscal policy kicks in, and a pick up in economic growth results."
Fed officials have indicated that three interest rate hikes are in the cards for this year, after approving just one increase in each of the past two years.
However, the Fed backed off its intended path in 2016 after growth disappointed and a series of geopolitical events caused unrest in the financial markets. FOMC members initially had projected four hikes in 2016 before settling on just one, passed in December.
Fed watchers continue to doubt whether the central bank will have the economic ammunition it needs this year to follow through on its rate normalization forecast.
Christopher Whalen, senior managing director at Kroll Bond Rating Agency, said the prospects for a 3 percent long-run funds rate remain dim despite the rise in government bond yields and hopes for better economic growth.
"While the movement of benchmark interest rates may suggest heightened inflation fears, and justifiably so given the statements from President Trump, KBRA remains far more concerned about the level of demand in the U.S. and a surging dollar," Whalen wrote.
Gains in the U.S. currency have spurred worries that it could slow growth. The Fed could be forced to shift course if it tightens into an economy that is still stumbling along, Whalen said.
"So far then, markets are operating on the assumption that we are in a rising interest rate environment," he said. "KBRA believes that this assumption deserves some skepticism."
