Middle East Chemical Supply Retains Cost Advantage Amid Hormuz Crisis

Middle East chemical exporters maintain long-term competitive advantages in global polymer markets despite ongoing Persian Gulf logistics constraints.

### Catalyst Analysis: What Changed - Persian Gulf shipping disruptions tied to the Iran conflict have constrained regional raw material capacity and raised polymer prices by more than 50% since March, according to market data. - Middle East polyethylene exports accounted for 43% of total global exports last year, shipping 18.7 million tons out of 43.8 million total global tons in 2025. - Propylene polymer exports fell 24% between April 2025 and April 2026, outperforming steeper declines in LNG (95%), urea (83%), methanol (80%), and ammonia (75%). - North American polyethylene exports reached 15.6 million tons last year, positioning regional producers to capture shifting supply share amid Persian Gulf bottlenecks.

### Impact on Mapped Tickers / Sectors - Global chemicals demand continues to prioritize low-cost production levers over temporary supply chain diversification risks. - High European energy costs and capacity reductions, alongside Asian naphtha constraints, provide operational tailwinds for alternative producers.

### Winners, Uncertainties & Risk Watch - **Winners:** Producers with secure domestic feedstocks and ample capacity able to capture market share during regional export drops. - **Uncertainties:** The duration of Strait of Hormuz transit bottlenecks and the long-term stickiness of diversified purchasing routes. - **Risk Watch:** Continued margin pressure on high-cost European and Asian petrochemical operators facing elevated regional input costs.
