Oil May Flow Through Strait of Hormuz First, Leaving Fertilizer Shipments Stranded

The interim peace agreement between the U.S. and Iran has raised hopes of easing tensions around the Strait of Hormuz, but available information suggests normalization of shipping will likely be uneven across cargo types.

Market observers expect crude oil shipments could resume sooner than other products. Oil markets are highly sensitive to geopolitical shifts and logistical stakeholders (charterers, insurers, and port operators) may prioritize crude given its market importance and more standardized handling requirements.

Non-crude cargos—such as refined fuels, liquefied gases and agricultural fertilizers—face additional practical hurdles. These cargos often require specialized tanks, dedicated handling and stricter safety or regulatory checks, meaning insurers and port authorities may be slower to clear them for transit compared with crude tankers.

Specific timings and volumes remain unreported. Key determinants will include the detailed terms and durability of the interim agreement, how quickly parties publish operational rules, the pace of insurance market normalization, and port readiness. Near-term indicators to watch are transit counts through the Strait, insurers’ underwriting stances, port capacity and customs processing updates.

Major uncertainties persist: the longevity of the agreement, the risk of renewed interference by third parties, and political shifts inside Iran or among regional actors. Any deterioration could delay or reverse initial reopenings, affecting a broader set of products.

In summary, based on information currently available, the deal may allow oil flows to recover first, while fertilizer and other non-crude supply lines may remain disrupted for longer. Stakeholders should monitor concrete operational data rather than rely on the diplomatic headline alone.

The Strait of Hormuz is a critical chokepoint for global oil shipments, so any change in its operating status materially affects energy risk premiums and supply expectations. If crude flows restart quickly while non-crude cargos remain constrained, crude prices could face downward pressure or reduced volatility, whereas continued fertilizer shortages would maintain upward pressure on agricultural input costs and related sectors. Operational factors—insurer underwriting, port readiness, and the durability of the interim agreement—remain uncertain and will determine how market signals evolve, making these items important to monitor from a macro-financial perspective.
