The Hormuz Crisis Isn't About Oil Anymore

Plastics Up 59%. Aluminum at a Four-Year High.

Three weeks ago, we covered the Strait of Hormuz shutdown and its immediate impact on oil and gas flows. Since then, the crisis has escalated. Ship transits through the strait have dropped from 130 per day in February to effectively zero. The IEA has called it the largest supply shock in modern oil market history.

But if your operations team is only tracking fuel costs, you're missing the bigger disruption.

The Materials Cascade

The Strait of Hormuz doesn't just carry oil. About a third of global seaborne methanol trade passes through it. So does 30% of internationally traded fertilizer, 9% of global aluminum output, and a significant share of sulfur, graphite, and petrochemical feedstocks (World Economic Forum).

Here's what's happening right now:

• Plastic resin prices in Asia have surged up to 59% since late February. The Middle East ships roughly 25% of the world's polypropylene and 20% of polyethylene (CNN). Hospitals in parts of Asia are running out of medical supplies. Factories face packaging shortages.
• Aluminum hit a four-year high last week. The UAE's Emirates Global Aluminium and Bahrain's Alba -- two of the world's largest smelters -- can't export through the strait (NPR).
• Urea fertilizer costs jumped 32% in a single week at the New Orleans import hub, from $516 to $683 per metric ton. Spring planting season is underway (PolitiFact).
• Methanol disruption is tightening supply of a feedstock critical to resins, coatings, and plastics manufacturing -- compounding the direct petrochemical losses (World Economic Forum).

The Timeline for US Operations

Asia is absorbing the first wave. The region accounts for more than half of global manufacturing and depends heavily on Gulf energy and materials imports. Gas stations in parts of South Asia are rationing fuel. Factories in Southeast Asia face packaging and input shortages.

For American manufacturers, the timeline is measured in months, not weeks. Industry analysts estimate three months before plastic shortages spread globally and four months before automakers need to cut production due to aluminum constraints (CNN).

Meanwhile, UPS implemented a Surge Emergency Fee on April 19 -- $0.23 per pound on most international shipments, $0.32 per pound from China and Hong Kong -- a direct reflection of rising fuel and transport costs hitting logistics budgets now (Supply Chain Dive).

What Operations Teams Should Do Now

Map your materials exposure. Identify which inputs in your bill of materials originate from or transit through the Gulf. Plastics, aluminum, fertilizer, methanol, sulfur, and graphite are the commodities to audit first. If your procurement team can't answer this question in 24 hours, you have a visibility gap.

Extend safety stock horizons. Standard buffer calculations assume normal lead times. Adjust for a 3-4 month supply disruption window on Gulf-dependent materials. If your supplier diversified to Asia after the 2025 tariffs, note that Asian manufacturers are already being squeezed on the same inputs.

Track commodity-level risk, not just shipping lanes. The disruption isn't uniform. Some materials have alternative sourcing routes; others don't. Orion tracks geopolitical and supply chain risk signals in real time, giving teams visibility into which commodity corridors are deteriorating before spot prices move.

Wrapping Up

The Hormuz crisis started as an energy story. It's now a manufacturing materials crisis with a clear timeline reaching US operations by Q3. Teams that audit their materials exposure and adjust safety stock now will have options. Teams that wait for the shortage to arrive won't.
