The global commodities complex is entering a phase where disruptions are no longer isolated—they are systemic. The ongoing conflict involving Iran and the United States, centered around the Strait of Hormuz, is now transmitting shocks across energy, agriculture, metals, and logistics simultaneously.
At the core is oil. Roughly 13 million barrels per day of crude supply, along with significant volumes of LNG, have been constrained due to intermittent closures and security risks in the Strait. Even with temporary ceasefires, flows remain inconsistent. The physical backlog is substantial: approximately 170 million barrels of oil are currently stranded on tankers inside the Gulf.
The recovery process is not straightforward. Clearing tanker congestion, restoring upstream production, and repairing damaged infrastructure could take months—or longer. This introduces a sustained risk premium into oil markets, with downstream effects on fuel prices. U.S. gasoline prices, currently above $4 per gallon, are expected to decline only gradually, contingent on geopolitical stabilization.
However, the more consequential effects may lie beyond oil.
Fertilizer markets are experiencing acute stress. Over 30% of global nitrogen exports have been disrupted, pushing urea prices sharply higher. In Argentina, prices have doubled to around $1,000 per ton, forcing farmers to reconsider planting strategies. Reduced fertilizer application today could translate into lower crop yields in the coming months, introducing upside risk to grain markets.
A notable distortion is emerging in the U.S., where domestic fertilizer remains significantly cheaper than global benchmarks. This has created arbitrage opportunities, leading to exports of fertilizer during peak planting season—a dynamic that underscores market inefficiencies under stress.
The fertilizer shock is closely linked to developments in metals, specifically through sulfur. As a byproduct of oil and gas production, sulfur is essential for both fertilizer manufacturing and metal extraction processes. With Gulf supply constrained, sulfur prices have surged.
This is increasing production costs in copper and nickel. Approximately 20% of global copper output relies on sulfuric acid in solvent extraction processes, leaving producers in regions like Chile and the Democratic Republic of Congo exposed. In nickel, Indonesian producers are already reducing output as input costs rise.
The cost implications are significant, with sulfur price increases adding thousands of dollars per ton to nickel production costs. This has contributed to recent price strength in both nickel and copper markets.
Logistics is amplifying these pressures. Tanker availability is constrained, freight rates are rising, and trade routes are shifting. Russia’s increased use of the Caspian Sea to export grain to Iran highlights how quickly flows adapt when traditional corridors become unreliable.
The broader implication is clear: commodities are now operating within a tightly interconnected system where disruptions propagate rapidly across sectors.
Even in a best-case scenario—where ceasefires hold and trade routes reopen—the path to normalization is likely to be slow and uneven. Markets are beginning to reflect this reality, but the full extent of the adjustment may still lie ahead.
