During the first quarter of 2026, global High-Density Polyethylene (HDPE) prices experienced a significant upward shift, with prices rising sharply across major regions. The USA recorded the most notable increase, with HDPE prices surging by 24.2% during the quarter. This strong price momentum was primarily driven by escalating geopolitical tensions between the United States and Iran, along with the closure of the Strait of Hormuz. The disruption severely impacted global logistics and constrained more than 40% of polyethylene shipments originating from the Middle East. As a result, crude oil prices climbed substantially, leading to higher feedstock and ethylene production costs, which further intensified the upward pressure on global HDPE prices.
