Japan Industrial Production Falls Amid Strait of Hormuz Closure

Japan's industrial production fell 0.5% month-on-month in March, marking a second consecutive monthly contraction and missing market expectations of a 1.1% increase. The downturn was primarily driven by a sharp drop in petroleum-based products and fuels, including a 27% decline in polyethylene output and a 15% fall in polypropylene.

These disruptions followed the effective closure of the Strait of Hormuz after US-Israeli strikes on Iran and subsequent Iranian retaliation. The closure hampered the flow of crude oil and naphtha to Japanese refineries. The Ministry of Economy, Trade and Industry reported that a 1.8-month inventory buffer for intermediate chemical products has limited immediate downstream disruptions, though manufacturers expect a further 0.7% adjusted decline in April before a potential 2.2% rebound in May.

Economic pressure is mounting as the industrial weakness coincides with slumping consumer confidence and a weak yen. These factors complicate the Bank of Japan's efforts to manage interest rates while facing rising inflationary pressures. Teikoku Databank warned that naphtha shortages could trigger price hikes for food products as early as the current summer, noting that food wrapping materials are already seeing price increases due to the Middle East conflict.
