Naphtha Shortage Hits Japan and South Korea

Blockade of the Strait of Hormuz and Regional Dependence
The Strait of Hormuz is a key route for crude oil and refined products to Asian markets. Before the blockade, Japanese and South Korean refineries obtained most of their naphtha from shipments passing through the strait, either directly from Qatar and Kuwait or as part of crude cargoes. The blockage has turned a global crude price spike into a localized naphtha scarcity.
Main Importers and Affected Industries
In Japan and South Korea, major importers include consumer-goods manufacturers, packaging firms, ink producers and medical-device makers. Asian refineries also depend on naphtha as a feedstock. With supplies cut, some food-packaging producers have begun stripping colors from packaging to conserve ink.
Timeline of the Disruption
- Early May 2026 – First reports of the Hormuz blockade.
- Mid-May 2026 – Qatar and Kuwait exports halted, limiting naphtha shipments.
- Late May 2026 – Japanese and South Korean firms report supply constraints.
- June 2026 (proj.) – Analysts warn shortages may spread to broader manufacturing.
Economic Ripple Effects
Naphtha is a feedstock for plastic wrap, industrial inks and medical-device components. The shortage has already forced Japanese consumer-goods firms to reduce color use in packaging to stretch limited ink. The ripple effect threatens sectors that rely on naphtha-derived polymers, potentially curbing production across the region.
Expert Assessment
Oxford Economics lead economist Toby Whittington said naphtha functions as the main conduit for Middle-East supply shocks across the economy and noted that it underpins many sectors, explaining why the current disruption has such broad impact.

Outlook and Mitigation
Japan and South Korea are seeking alternative naphtha supplies ahead of the projected June escalation. Industry groups are exploring diversified feedstock options and stockpiling. The duration of the Hormuz blockade remains uncertain, leaving the region’s manufacturing outlook dependent on the restoration of uninterrupted maritime flows.
