Strait of Hormuz Closures Threaten Global Supply Chains Beyond Oil and Gas
If the disruption persists for a few more months, analysts warn it could trigger widespread stagflation by choking off essential petrochemical feedstocks.
Petrochemical Feedstocks and Naphtha Shortages
The Middle East normally supplies about 30 percent of global seaborne exports of liquefied petroleum gas, which serves as a vital petrochemical feedstock. Drewry analyst Anshika Prajapati estimates that a prolonged closure of the 20-mile-wide waterway cuts off 24 percent of global seaborne naphtha. This leaves major Asian manufacturing hubs scrambling for alternative inputs to keep industrial production running.
Geopolitical Shift in Petrochemicals and Food Supply Chains
While South Korea, Taiwan, and Japan hold significant petrochemical export capacity, their electricity-intensive plants rely heavily on liquefied natural gas. Conversely, Chinese firms with access to abundant domestic electricity and Russian feedstocks like naphtha could consolidate parts of the market, increasing Beijing’s geopolitical leverage.
Energy Importers Diversify Supply Networks
Six months into the conflict, increased production and emergency stockpiles have prevented worst-case economic collapses. However, the crisis acts as a major wake-up call for energy importers like Japan, which previously relied on the Middle East for 90 percent of its crude oil and 11 percent of its liquefied natural gas, according to Saul Kavonic, head of energy research at MST Financial. Tokyo is now investing in alternative projects, such as an expanded liquefied natural gas venture in Australia’s Northern Territory led by Inpex.
Did you know? Before the conflict, roughly 20 percent of the world’s oil trade passed through the Strait of Hormuz, with more than 80 percent of that cargo bound for Asian economies like China, India, Japan, and South Korea.
Frequently Asked Questions
Why is the Strait of Hormuz critical for global trade?
The 20-mile-wide waterway handles a massive share of the Middle East’s oil and gas exports, serving as a primary transit route connecting Middle Eastern producers to major energy-importing economies in Asia.
How have Asian countries responded to the energy restrictions?
Importers have imposed export bans, adjusted import duties, and initiated fuel rationing while investing in alternative energy sources outside the Middle East, such as projects in Australia.
What commodities beyond oil are affected by the waterway’s closure?
