The joint U.S.–Israel strike on Iran and Tehran’s missile response have put global energy and chemical supply chains on edge . Markets fear not only higher oil prices but also fresh disruptions to critical shipping routes and feedstocks.
Why the Strait of Hormuz Matters
The Strait of Hormuz is the world’s busiest energy chokepoint. Each day about 20 million barrels of crude and refined products pass through it — roughly 20 % of all oil consumed worldwide . Nearly 20 % of LNG exports also use this corridor . The strait links the Persian Gulf to the Indian Ocean; Saudi Arabia, the UAE, Iraq, Kuwait, Qatar and Iran rely on it for most of their oil exports, which together account for roughly 80 % of OPEC’s output . Alternative pipelines can handle only 15–20 % of that volume . Analysts warn that a closure could add US $2–5 per barrel to transport costs and push prices $30–70 per barrel higher .
Lessons from the Red Sea Crisis
In late 2023, Yemen’s Houthi rebels attacked ships in the Red Sea, forcing carriers to bypass the Suez Canal and sail around Africa’s Cape of Good Hope. This detour added 3 000–3 500 nautical miles and 10–14 days to Asia–Europe routes . Freight rates spiked — container prices to Europe tripled and insurance premiums for sailing through the Red Sea jumped from $10 000–20 000 to $150 000–500 000 . Chemical cargoes were hit especially hard because about 30 % of global ocean traffic usually passes through the Red Sea, and some chemical freight rates became three times more expensive . The diversion cost shippers an extra $200–400 per TEU and reduced effective vessel capacity worldwide.
Shipping in 2025–26: A Fragile Recovery
By early 2026 some carriers cautiously returned to the Red Sea. Long‑term contract rates from Asia to the Mediterranean fell 25 % compared with late 2025 and 10 % to Northern Europe . Yet they remain 45–58 % above 2023 levels . Analysts warn that another Houthi attack or escalation around the Strait of Hormuz could send ships back around Africa and reignite cost spikes .
Impact on the Chemical Industry
Iran is not a major gas exporter but it is a top supplier of methanol and a significant exporter of ammonia, urea and polymers . Disruptions to Iran’s ports or the Strait of Hormuz would tighten global supplies of these feedstocks, potentially raising prices. Europe’s chemical sector is already under strain from high energy costs and plant closures , so any additional interruption could lead to further shortages or shutdowns.
Key Takeaways
- Energy chokepoints: The Strait of Hormuz carries about 1/5 of the world’s oil and 1/5 of its LNG . Disruption would cause large price spikes.
- Red Sea diversion: Rerouting around Africa adds 10–14 days and $200–400 per TEU in extra cost .
- Insurance premiums: War‑risk insurance through the Red Sea rose from $10 k to $150–500 k per voyage during the crisis .
- Chemical feedstocks: Iran supplies around 10 % of China’s methanol demand ; any disruption could affect global prices.
- Recovery is fragile: Shipping rates remain elevated and could surge again if hostilities expand .
As tensions continue, companies should prepare for higher freight costs and potential delays. Chemicals United stands ready to support customers during these disruptions by providing essential chemical products and leveraging resilient logistics networks to keep deliveries flowing even when key shipping lanes are threatened.
