Impact of the Iran War on Global Fertilizer Supply and Food Prices

Fertilizer Supply Disruptions Amid Conflict
The ongoing war in Iran has significantly disrupted global fertilizer supplies, with critical implications for food prices in the United States. The Strait of Hormuz, a vital shipping route through which approximately one-third of the world’s fertilizer ingredients transit, has been effectively shut down due to military actions since February 28. This closure has led to heightened tensions, with Iranian military forces attacking cargo ships and concerns about sea mines being planted in the strait. As a result, shipping companies are avoiding the area, causing a backlog of tankers and a surge in oil prices, which recently topped $99 a barrel.
Rising Fertilizer Costs and Agricultural Impact
The conflict has already caused substantial increases in fertilizer prices. As of March 10, ammonia prices in the Middle East rose by 92% compared to the previous year, while urea prices increased by 70%. In the U.S., ammonia prices are up 41% year-over-year, and urea prices have risen by 21%. John Boyd Jr., a Virginia farmer, expressed concerns about the availability of fertilizer, stating, “The dealers are telling me we can’t get the fertilizer... due to the war and the bombing through that area.” With the spring planting season underway, any further disruptions could severely impact crop yields and food security.
Broader Economic Implications
The fertilizer crisis is not isolated; it is part of a larger trend affecting various sectors. The war has also led to rising diesel prices, which are essential for agricultural operations. Boyd noted that filling his tractor with diesel now costs him $469, adding financial strain to his farming activities. Agriculture Secretary Brooke Rollins acknowledged that while most farmers have secured their fertilizer needs, about 25% remain vulnerable to rising prices.
Retail Sector and Consumer Prices
The ripple effects of the conflict extend to the retail sector, where rising input costs are expected to lead to higher grocery prices. Max Kahn, president of Coresight Research, indicated that food items, due to their less flexible supply chains, may see price increases first. Retailers are facing dual pressures from rising costs and shifting consumer demand, particularly as discretionary spending declines due to higher fuel prices.
Criticism and Concerns
Critics have raised alarms about the long-term implications of the fertilizer supply disruptions. Analysts warn that the situation could lead to lower crop yields in regions dependent on imports, such as India and Bangladesh, potentially exacerbating global food price inflation. The American Farm Bureau Federation has called for naval escorts for fertilizer shipments through the Strait of Hormuz to ensure supply continuity.
What's Next?
As the conflict continues, the U.S. government is reportedly close to announcing measures aimed at stabilizing fertilizer costs for farmers. However, the effectiveness of these measures remains to be seen, especially as the agricultural sector faces the critical spring planting window. The ongoing situation in the Strait of Hormuz will be pivotal in determining the future of global fertilizer supplies and food prices.

- “If I don’t apply fertilizer, that means I won’t have the yields to make my crop,” — John Boyd Jr., Farmer
- “These supply chain shocks are expected to drive already record-high input prices even higher at a time when farm margins are already extremely tight, and many farmers are underwater,” — Zippy Duvall, AFBF President
- “The rise in oil prices should add a meaningful burden to household budgets and intensify strains already visible across the consumer landscape,” — UBS Analysts
The intersection of geopolitical conflict and agricultural economics underscores the fragility of global food systems, with the potential for far-reaching consequences if the situation does not stabilize.
