The blockade of the Strait of Hormuz has sent international oil prices into a spiral, triggering a violent cost transmission across the chemical industry. On March 6, WTI closed at $90.90/barrel. This isn't just an energy spike; it is a direct threat to the manufacturing costs of composite materials.

1. Raw Material Cost Transmission (USD Index)

As of March 9, Styrene has seen a rapid 8.99% increase. This has driven an immediate price hike of $130 – $145 per ton across various resin categories.

2. Analysis: Why Prices Will Continue to Climb

The crisis is deepening as Middle Eastern producers begin shutting down oil fields, leading to a physical reduction in supply. Simultaneously, domestic refineries are reducing loads due to natural gas and oil shortages. This double-squeeze ensures that raw material prices will remain volatile until strategic reserves are released or shipping routes normalize.

3. Market Reaction: The "Cooling Window"

Currently, the market is entering a "price without volume" phase. While costs are at record highs, downstream acceptance is low. In key regions like North and East China, UPR production loads are dropping significantly.
