WASHINGTON — U.S. factory output slid last month as a shortage of computer chips disrupted auto production.

Manufacturing production dipped 0.1% in June — third drop in five months, the Federal Reserve reported today.

Overall, industrial production — including output at factories, mines and utilities — rose 0.4% last month after increasing 0.7% in May. Industrial output is up 9.8% from a year earlier.

The chip shortage pushed production of cars, trucks and auto parts down 6.6% in June. Excluding autos, industrial production rose 0.4% last month.

Utility output climbed 2.7% in June as Americans cranked up the air conditioning to battle a heat wave across much of the country. Mining output rose 1.4% on an uptick in oil and gas production.

American industry has been bustling as the coronavirus threat recedes, despite a shortage of workers and trouble getting supplies in time. The Institute for Supply Management, an association of purchasing managers, reported that its manufacturing ticked slightly lower last month compared to May. But it came in at 60.6 on a scale where anything above 50 signals growth. Factory hiring shrank, ISM found, largely because manufacturers are struggling to fill job openings as the economy rebounds with unexpected speed from the coronavirus recession.
