How Middle East Disruption Is Reshaping Asian Supply Chains

Since the Middle East conflict began on February 26, vessel traffic through the Strait of Hormuz has fallen by 95.3%, according to UNCTAD data released on April 28. The International Energy Agency (IEA) has described this as the largest supply disruption in oil market history, with global markets losing nearly 13 million barrels of oil per day. At the same time, global commodity food prices have risen by 6%, and European crude oil prices by 53%. The S&P 500‘s global supply shortages indicator has exceeded its long-term average for the first time in three years. The shock has spread from the energy sector to manufacturing, agriculture, logistics, etc.

Asian supply chains are most tightly coupled to the Middle East. Asia is the factory floor for much of the world, including the United States — when Asian supply chains tremble, global supply chains feel it.

Asia Supply Chains Under Pressure

The well-documented dependence of the Strait of Hormuz on energy resources belies a broader impact on Asian manufacturing supply chains. While public attention during such a blockade tends to focus almost exclusively on oil prices, the ripple effects extend far more widely. The current risks are pushing up oil prices, raising transport and energy costs, and are causing petrochemical shortages — factors that disrupt Asian manufacturing supply chains far more significantly than simple fuel supply concerns.

Petrochemicals First: A Chain Reaction of Shortages

The Middle East is a major source of petrochemical feedstocks, accounting for approximately 20-25% of global polypropylene and polyethylene supply, while also supplying large quantities of sulfur, urea, helium, and aluminum — all of which are relied upon by numerous Asian manufacturers. The Strait closure has forced major petrochemical producers such as South Korea’s Yeochun and Singapore’s PCS to declare force majeure, rendering them unable to fulfill their commitments to customers. Naphtha and LPG shortages have emerged in Japan, Indonesia, and other countries and regions, with some companies forced to reduce production.

Downstream industries such as plastics, packaging, and textiles face the dual risks of rising raw material prices and production stoppages. Global chemical giants such as BASF and Lanxess have announced significant price increases, with some products rising by as much as 30%, and cost pressures are rapidly transmitting downstream to manufacturing and consumers.

Price Shocks Spread to Industry and Manufacturing

Beyond petrochemicals, key materials such as aluminum and helium are also facing supply disruptions, with Qatar Aluminum shutting down production lines and Bahrain's Alba suspending shipments. Rising aluminum prices are directly impacting auto manufacturing, particularly new energy vehicles, where aluminum alloys are critical for bodies, battery casings, and wheel hubs. This price pressure extends throughout the broader manufacturing chain—including power electronics, construction, and transportation—directly pushing up production costs across multiple industries.

Helium shortages threaten chip manufacturing, potentially suppressing semiconductor exports from South Korea and Taiwan.

Shipping Costs Surge, Adding Another Layer of Pressure

Beyond raw materials, maritime logistics is also under severe strain. The rerouting of vessels around the Cape of Good Hope — while avoiding the Strait of Hormuz — has added 10 to 20 days of transit time and increased fuel consumption by approximately 15%. Meanwhile, war risk insurance premiums for vessels transiting the Middle East have tripled. As a result, spot container rates from Asia to Europe and North America have risen sharply, with carriers announcing multiple general rate increases. These shipping cost pressures are ultimately passed on to manufacturers and consumers, further eroding margins across supply chains.

In March 2026, disruptions emerged at major regional hub ports including Singapore, Colombo, and Mundra, as container vessels sought alternative routes, creating downstream pressure on distribution networks across the region.

Country Responses: Trade Moves & Energy Shifts

In response to these cascading pressures, Asian governments have rolled out emergency measures. According to Global Trade Alert (GTA) data, governments of multiple countries, including those in Asia, have implemented over 250 countermeasures since the conflict began, including fuel tax subsidies, consumption tax reductions, and tariff exemptions for chemicals and fertilizers. India has implemented temporary tariff exemptions on ammonium nitrate and plastic feedstocks, Turkey has reduced fertilizer import tariffs, and nine Asian economies including Bangladesh, Indonesia, and the Philippines have introduced energy consumption reduction policies.

At the same time, energy import diversification is accelerating. Indonesia, Vietnam, Thailand, and the Philippines are turning to Russia for crude oil, LNG, and fertilizers to circumvent Middle East supply disruptions. The United States has also temporarily eased sanctions enforcement on Russian energy, though this remains politically fragile.

China: Under Pressure, but Structurally Resilient

China is also highly dependent on Middle Eastern crude oil and petrochemical feedstocks such as polyethylene, polypropylene, and MEG. However, China is demonstrating unique strategic resilience amid the current turbulence. It has diversified its crude oil imports from 49 countries, reducing single-point failure risk. China has also established overland transport corridors and pipeline networks. By 2025, overland transport corridors account for 38% of total oil transport, serving as a critical backup when sea lanes are blocked. Its crude oil pipeline network has an annual transmission capacity of 345 million tons, and its natural gas pipeline network has approximately 420 billion cubic meters. In addition, China maintains a large and expanding reserve system: by the end of 2025, its crude oil reserves covered approximately 110 to 180 days of net import demand, and by the end of 2026, total oil storage is expected to exceed 2 billion barrels. Moreover, the widespread adoption of new energy sources in China — including electric vehicles, solar and wind power, and industrial electrification — has significantly eased the pressure on oil demand. As of 2025, China’s new energy alternatives are estimated to displace over 2 million barrels per day of crude oil equivalent according to BloombergNEF, reducing import growth and providing a structural buffer against supply shocks. Finally, precise policy interventions — including price interventions, reserve releases, and industry subsidies — have stabilized market expectations. During the 2026 crisis, China's domestic oil price volatility reached only half that of international markets.

As energy shortages disrupt production in several ASEAN economies, China's relatively stable industrial base positions it to absorb some relocated orders. However, Chinese downstream SMEs remain exposed to spot petrochemical price volatility.

Recommendations for Companies

The Strait of Hormuz blockade has now lasted three months, with no clear end in sight. For companies operating in or sourcing from Asia, these dynamics demand immediate, practical adjustments.

1. Map your sub-tier supply chain risk. Identify which of your products depend on plastics (polypropylene, polyethylene) from Asian manufacturers that rely on Middle Eastern feedstocks. Perform the same analysis for aluminum, helium, and fertilizers.

2. Identify alternative supply sources outside the Gulf. For aluminum, consider smelters in North and South America (Canada, Brazil). For fertilizers, sources in the U.S., Canada, and certain Russian suppliers (where sanctions permit) can help. For helium, U.S. sources can provide partial alternatives, though volumes are limited.

3. Incorporate geopolitical lead times into inventory models. Assume that Strait of Hormuz disruption or uncertainty will persist for 6 to 12 months. Adjust safety stock calculations accordingly.

4. Review contracts for force majeure and freight volatility clauses. War risk insurance premiums have tripled. Many shipping lines are invoking force majeure. Review cost and liability sharing provisions in supplier and logistics contracts. Review your in-transit inventory ownership and financing terms, especially for buyers using letters of credit.

5. Run scenarios. Develop at least three planning scenarios:

   
   

   (a) the Strait reopens within three months;

   
   

   (b) disruption continues through 2026;

   
   

   (c) partial reopening with intermittent security incidents.

   
   

   Assign probability ranges and action triggers to each scenario.

Geopolitical developments are beyond any single company's control, but supply chain resilience is not. Companies that identify their risks, build buffers, and diversify their sources will be far better positioned than those that wait for shortages to reach their home markets.
