Japan’s manufacturing PMI jumps to 55.1, but supply pressures raise concerns about sustainability

Japan’s manufacturing PMI reading finished at 55.1 in April, up sharply from 51.6 in March and representing the strongest reading since January 2022. The data points to a strong rebound in factory activity, with production expanding at the fastest pace in more than a year, supported by rising sales and increasing production momentum.

However, the strength of activity is partly driven by precautionary behaviour. According to S&P Global Market Intelligence, manufacturers have been boosting inventories amid growing supply chain disruptions linked to the conflict in the Middle East. Lead times on inputs have deteriorated at the fastest rate in 15 years, while input cost inflation has risen to the highest level in three-and-a-half years, highlighting growing pressures across production networks.

As Annabelle Vides notes, the current recovery may be short-lived. “This suggests that the current push for manufacturing may soon fade unless we see reduced market uncertainty and more stable supply chain conditions,” she said, warning that the rebound in activity is linked to inventory building rather than sustained demand. Without improved supply conditions, higher costs and weak demand could impact the sector in the coming months.
