US HDPE Prices Rise 7.7% Amid Feedstock Tightness and Geopolitical Disruptions

HDPE markets in the United States extended a robust upturn into early April, driven by tight feedstock flows, geopolitical disruptions and sustained downstream demand. March saw re-pricing after export licensing changes and ethane cargo disruptions, with momentum carrying into mid April as global buyers boosted inquiries. Robust procurement by packaging and infrastructure converters, together with constrained global cracker output, kept sellers confident and tightened spot availability across HDPE grades. Domestic producers maintain pricing power given a domestic supply share near 90%, while spot benchmarks firm and liquidity remains constrained.Upstream factors amplified the cost base, including elevated ethylene values and sustained crude strength, and tighter ethane supply due to export licensing and regional disruptions. The market showed a week-on-week gain of about 7.7% into mid April, reflecting persistent monomer tightness and export demand. Looking forward, prices are expected to stay firm unless logistics ease, crackers restart, or geopolitics shift, suggesting near-term procurement should factor narrow spot availability and elevated risk premia.
