US factory production regained its footing in April to push capacity utilisation to the highest since 2015, indicating the industry will support economic growth this quarter, Federal Reserve data showed Wednesday.

The gain in factory output was broad-based outside of a decline in motor vehicles and parts. Several categories posted increases of more than 1 per cent, including machinery; computer and electronic products; electrical equipment and appliances; and aerospace and miscellaneous transportation.

The factory-use rate rose to 75.8 per cent — the highest since August 2015 — from 75.5 per cent a month earlier. Even so, that’s still 2.5 percentage points below its long-run average.

The results bolster the view that the industry, along with consumer spending, will contribute to a projected second-quarter rebound in economic growth. Tax cuts and steady overseas sales are expected to underpin gains in business investment. At the same time, rising prices for materials and tariffs on imported metals, along with US-China trade tensions, pose risks for American manufacturers.

Automobile and parts production decreased 1.3 per cent after two months of strong gains, the Fed’s report said. That’s consistent with government figures based on industry reports and released earlier, which showed motor-vehicle sales cooled in April.

Revisions to data had the effect of paring gains in factory production in the first three months of the year. Manufacturing output rose at an annual rate of 1.4 per cent in the quarter, down from a previously reported 3.1 per cent. That followed a 5.2 per cent gain in the fourth quarter of 2017, which was the best since early 2012.
