Propylene in the United States strengthened through March as tightening feedstock conditions and geopolitical disruption trimmed merchant supply at month’s end. Early observations flagged pressure from higher crude and naphtha costs and announced maintenance at several PDH and petrochemical units that narrowed domestic availability. Export loadings and terminal expansions redirected propane offshore, while Hormuz-related disruptions further constrained inbound NGL flows, prompting an appreciable repricing move. Buyers pursued measured restocking for polypropylene production rather than speculative bets, keeping activity focused on physical flow and logistics risk. Demand from polymer producers remained the primary support, bolstering PP applications such as packaging, consumer goods and automotive components. Domestic PP contracts rose modestly, reinforcing buying interest. The market remained tight as domestic output continued to meet the bulk of consumption, but merchant pools thinned and spot activity intensified. Planned maintenance and logistics constraints, plus higher feedstock costs, underscored upside risk, with seasonal pre-summer demand sustaining buying into spring, subject to geopolitical and operational developments.
