The latest report by IHS Markit revealed on Tuesday the seasonally adjusted IHS Markit final U.S. Manufacturing Purchasing Managers’ Index(PMI) came in at 62.1 in May, up from 60.5 in April and from the earlier released “flash” reading of 61.5. The May reading pointed to another record growth in factory activity in the 14-year series history.

Economists had forecast the index to stay unrevised at 61.5.

According to the report, the May gain in headline figure was supported by stronger expansions in output and new orders, with the pace of the latter reaching the fastest on record. Nonetheless, constraints on production capacity were exacerbated further during the month, as severe supply-chain disruptions led to a marked accumulation of backlogs of work and one of the quickest rises in input prices since data collection began in May 2007.
