Sulphur prices in the United States increased sharply from late April to early May 2026, supported by tight global supply, logistical disruptions, and strong demand from the fertilizer sector. Geopolitical tensions in the Middle East, including the blockade of the Strait of Hormuz, significantly restricted exports and caused major production losses across key suppliers. At the same time, limited global production growth reduced the market’s ability to respond to shortages. Rising fertilizer demand further strengthened sulphur consumption. Ongoing shipping constraints and prioritization of long-term contracts have tightened spot availability, and the market is expected to remain firm in the near term.
