ASEAN's manufacturing activity strengthened further in November, with growth momentum accelerating to one of the fastest levels on record, according to a report released by S&P Global on Monday.

The S&P Global ASEAN Manufacturing Purchasing Managers' Index rose to 53.0 in November from 52.7 in October, indicating further expansion during the month.

Stronger increases in both output and new orders supported the November expansion, with growth rates among the most robust in the survey's history.Firms also expanded purchasing activity at the fastest pace since March 2024, reportedly.

Furthermore, employment increased for a third consecutive month, though hiring remained marginal.

On the price front, inflation rose, with input costs rising at the quickest pace in nearly a year. Firms raised selling prices in response, although both input and output inflation remained historically moderate, S&P said.

Looking ahead, manufacturers across the region remained optimistic, expecting output growth over the coming year. However, confidence levels stayed below the long-run average, the report added.

The survey covers manufacturers in Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Vietnam.
