Global Fertilizer Supply Chains Face Renewed Pressure Amid Hormuz Strait Disruptions

The global fertilizer market is currently navigating a period of significant complexity, marked by persistent challenges to supply chains and logistics. What began as geopolitical pressures on energy and shipping sectors has evolved into a structural test for the entire agricultural supply chain, with the situation remaining dynamic as of June 2026.

The Strait of Hormuz, a critical maritime chokepoint, recently saw a brief period of recovery following a US-Iran peace agreement, but this was swiftly reversed. Iran's Islamic Revolutionary Guard Corps (IRGC) declared the waterway closed on June 21, citing Israeli actions in Lebanon. This declaration led to a sharp reduction in vessel transits, with ship tracking data indicating a drop from 35 vessels on Saturday to just 12 on Sunday, according to Alkagesta, a trading firm specializing in nitrogen, phosphate, and specialty fertilizer products. Alkagesta focuses on establishing long-term supply partnerships across Europe, the Middle East, North Africa, and key agricultural markets, sourcing from diverse global origins to meet demand where agricultural fundamentals are strongest.

Structural Vulnerabilities in Fertilizer Supply

The ongoing crisis has underscored the inherent vulnerabilities within the global fertilizer supply chain, which has historically prioritized efficiency over redundancy. Approximately one-third of all internationally traded fertilizers traverse the Strait of Hormuz, concentrating significant volumes through a single, critical chokepoint with minimal alternative routes. Previous disruptions saw urea prices exceed $800 per tonne FOB Egypt, and force majeure clauses were invoked on contracts previously considered robust. Producers in South Asia also reduced output due to tightening Qatari gas supplies.

Even the temporary reopening of the Strait after the June 14 US-Iran agreement failed to restore normal shipping volumes, with tanker transits peaking at only 25 vessels on June 19, significantly below the pre-conflict baseline of over 100 daily transits. The subsequent closure by the IRGC days later reinforced the understanding that restoring physical supply flows is a gradual process, not an immediate event, suggesting that market normalization will not occur rapidly.

Global Implications and Market Response

The repercussions of the Strait's instability extend far beyond fertilizer logistics. Qu Dongyu, Director-General of the Food and Agriculture Organization (FAO), emphasized at the 181st Session of the FAO Council that the closure of the Strait represents a global food security risk, noting that 20-30% of global fertilizer exports pass through this vital passage. In response, G7 agriculture ministers convened an extraordinary session to coordinate efforts on supply diversification and enhance market transparency.

In this challenging environment, the timely and accurate delivery of products has become as crucial as price discovery, according to Alkagesta's Fertilizer Desk Lead, Vusal Muradov, in a recent analysis. Fertilizer demand is highly seasonal, meaning that missing a delivery window can result in the loss of an entire growing season. Alkagesta's desk manages the complexities of product specifications, storage, port infrastructure, inland logistics, and multi-jurisdictional regulatory requirements, while closely monitoring energy and ammonia markets due to their direct influence on nitrogen fertilizer production economics.

The volatility observed in these markets indicates continued instability. The brief reopening and swift re-closure of the Strait underscore that market participants should not anticipate a quick return to pre-conflict operating conditions. For fertilizer buyers and traders, the implications are substantial, as planting seasons proceed irrespective of geopolitical developments, and supply chains cannot be rebuilt instantaneously, even when shipping lanes become accessible. Businesses best positioned to navigate this period are those that developed robust sourcing relationships, logistical flexibility, and strong execution capabilities prior to the onset of disruptions, rather than in reaction to them.
