USGC butadiene markets extended firming into May as prompt availability tightened and buyers had limited options. Supply pressures began in early April from crowded terminals due to Gulf Coast methanol exports, followed by a mid-April squeeze after an unplanned outage at SABIC's Jubail complex curtailed a key Middle Eastern supply line. The tone shifted from neutral to firmer as sellers resisted discounting and buyers had fewer alternatives. Demand was mixed: synthetic rubber buyers supported price strength at times, though some rubber producers trimmed run rates on margin pressures, tempering downstream uptake. Consumer electronics demand remained soft, dampening some derivative flows, while general downstream buyers maintained steady buying that underpinned prices late in the period. Logistics congestion and elevated freight costs added upside risk, with Gulf Coast methanol crowding terminals cited as a key factor. Upstream dynamics-ethane-heavy cracker feeds reducing C4 yields tightened prompt supply alongside reduced import options after Jubail. Outlook for Butadiene remains firm-to-higher with continued seller reluctance to release volumes.
