Overview
- Government data show a 0.5% month-on-month drop in March, the second straight fall and a miss versus a 1.1% rise forecast.
- Petrochemical and fuel output led the slide, with polyethylene down 27%, polypropylene 15%, gasoline 7.3%, and diesel 14.3%.
- The drop tracks crude and feedstock shortages tied to an effective shutdown of the Strait of Hormuz, and Japan buys about 95% of its oil from the Middle East.
- METI said inventories for intermediate chemical goods equal about 1.8 months of supply, which has kept most downstream shipments on schedule for now.
- Makers in a METI survey expect a 0.7% fall in April before a 2.2% rebound in May, as the Asian Development Bank cut its 2026 growth outlook on energy disruption.
