Impact of The March 2026 US–Israel–Iran War on the Oil, Chemicals, and Materials Industries

The ongoing the March 2026 US–Israel–Iran War is sending shockwaves through global markets, particularly impacting oil, chemical raw materials, and downstream materials. Understanding how these effects cascade from crude oil to everyday products is critical for businesses, investors, and policymakers alike.

1. Oil Market: Supply Risks and Price Surges

The Middle East is home to key oil-producing nations, and a large share of global crude transport passes through strategic chokepoints such as the Strait of Hormuz. The conflict has caused:

• Transport disruptions: Shipping routes are under threat, raising insurance and shipping costs.

• Supply chain tightening: Approximately 20% of the world’s oil passes through the Strait of Hormuz, so any blockage or risk triggers a global price surge.

• Price volatility: International crude oil prices have already risen by 7–10% in early March 2026. Analysts suggest that prices could even exceed $100 per barrel if the conflict escalates.

Key takeaway: Higher oil prices drive up costs across industries that rely on crude oil or natural gas as raw materials or energy inputs.

2. Upstream Chemical Raw Materials

Crude oil and natural gas are the building blocks for most basic chemical materials. When oil prices rise, the cost of producing these chemicals also increases. Key affected raw materials include:

Material	Primary Use	Impact of Conflict
Ethylene	Plastics (PE, PP), synthetic fibers, rubber	Cost increase → higher plastic product prices
Propylene	ABS plastics, acrylics, coatings	Production cost rises → downstream materials more expensive
Benzene	Synthetic rubber, solvents, pharmaceuticals	Price spike → rubber, solvent, and chemical intermediate costs increase
PX (Paraxylene)	PET bottles, polyester fibers	Cost transmission → textile and packaging costs rise
Methanol	Chemical intermediates, formaldehyde, fuel additives	Price surge → impacts solvents and agrochemical intermediates

3. Downstream Chemical Products

The impact on raw materials propagates to downstream products, which are closer to end consumers:

Product Category	Examples	Impact Mechanism
Plastic products	Packaging films, containers, automotive parts	Higher ethylene and propylene costs → more expensive plastic goods
Synthetic fibers	Polyester, nylon	PX and ethylene price increases → textile and apparel costs rise
Rubber & Tires	Vehicle tires, industrial rubber products	Benzene and butadiene cost spikes → rubber product prices increase
Coatings & Solvents	Industrial and household paints, cleaning solvents	Propylene and benzene price increase → higher production costs
Agrochemicals	Pesticides, herbicides	Methanol and benzene cost increase → input costs rise
Pharmaceuticals & Electronics materials	Medicine intermediates, PCB chemicals	Cost pressure from upstream chemicals → slight price increase

Summary for readers: If you manufacture or use plastics, textiles, rubber, paints, or certain chemicals, the conflict can make raw materials more expensive, squeezing profit margins.

4. Logistics and Supply Chain

• Disruptions in shipping routes in the Middle East increase transportation and insurance costs.

• Delays and shortages in chemical raw materials affect global supply chains, impacting countries far beyond the conflict region.

• Companies dependent on imported chemicals may face higher costs and stock shortages.

5. Affected Countries

The following countries are most impacted by these disruptions in oil and chemical trade:

Region	Example Countries
Middle East (conflict zones)	Saudi Arabia, UAE, Iran, Syria, Yemen
Major importers affected by price spikes and supply risks	USA, EU countries, China, India, Japan, South Korea

Explanation: Even though the war is in the Middle East, countries worldwide experience cost pressure through global oil and chemical supply chains.

6. Macro Implications

1. Inflation pressure: Rising oil and chemical costs can pass through to consumer goods, industrial products, and logistics, potentially fueling global inflation.

2. Investor behavior: Oil, gas, and related chemical sectors may attract investors as “defensive” or hedging assets during geopolitical instability.

3. Supply chain strategy: Companies may seek alternative suppliers or diversify production locations to reduce dependency on high-risk regions.

7. Opportunities and Long-Term Trends

• High oil prices may favor bio-based chemicals, green solvents, and renewable materials, creating long-term growth opportunities.

• Companies that can optimize supply chains or switch to lower-cost, locally sourced raw materials may gain a competitive advantage.
