U.S. employment costs rose less than forecast in the fourth quarter as wage and salary gains cooled, adding to signs that inflation pressures remain mild despite a strong job market.

The employment cost index, a broad gauge monitored by the Federal Reserve, increased 0.7 per cent in the October-December period from the prior quarter, according to Labor Department data released Thursday. That compared with the median estimate of economists for a 0.8 per cent increase. Wages and salaries rose 0.6 per cent following a 0.9 per cent gain in the prior period.

Key Insights

- While employers are paying more and boosting benefits to retain workers as it becomes ever harder to hire, the data show little sign of a major pickup in compensation. Among private workers, the deceleration in the index over the quarter was more pronounced, with a 0.6 per cent increase.

- At the same time, compensation costs have risen enough to help push the employment-cost index up 2.9 per cent from a year earlier, the most since 2008.

- The lack of a big acceleration in labor costs reinforces the Fed's decision this week to indicate it will forgo interest-rate hikes for at least a while as various global risks mount. Policy makers on Wednesday cited “muted inflation pressures” as they shifted to a patient approach to future rate moves following four hikes in 2018.

- Growth in average hourly earnings, a separate monthly measure of private-sector wages that can be influenced by shifts in industry employment and hours worked, recently picked up above 3 per cent for the first time since the economic expansion began.
