Strait of Hormuz closure tightens energy margins as Asia inflation climbs

Iran closed the Strait of Hormuz following US attacks, cutting access to roughly 20 percent of global oil transport. Oil prices rose immediately. Asian equity markets slid as the closure priced into energy-dependent supply chains. Saudi Arabia increased jet fuel shipments to Europe above pre-closure levels, rerouting supply around the choke point, but the arbitrage spread widened.

Indonesia raised widely used fuel prices by 32 percent, citing the need to stem a market rout as imported energy costs climbed. The government called it a bitter pill. Cost-of-living concerns intensified across Southeast Asia. US consumer inflation is expected to show another increase in May, driven by higher gasoline prices even before the Hormuz closure fully propagated through refining and distribution.

China's factory-gate inflation reached a nearly four-year high in May. Producer price pressure is building as input costs rise and domestic demand remains soft. Beijing continues to promote AI adoption across state and private enterprises, and Reuters reports Chinese companies are deploying quiet layoffs in parallel—headcount reduction without formal announcements, consistent with workforce replacement rather than expansion.

The Bank of Japan is now expected to raise its key rate to 1.0 percent in June and 1.25 percent by year-end, according to a Reuters poll. That marks a structural shift: Japan pricing in sustained inflation and unwinding a decade of zero-rate policy. Energy cost pass-through is a cited factor.

The Hormuz closure is a supply shock, not a demand signal. It compresses margins for energy buyers and raises baseline costs for compute infrastructure, logistics, and manufacturing.
