Disruption to energy flows through the Strait of Hormuz is exacerbating global food shock risks as higher gas prices squeeze fertilizer production. The critical waterway handles roughly 20% of global oil and LNG exports and 30% of seaborne fertilizers, making it essential for both energy and food supply chains. Traders warn reduced LNG flows have already curbed industrial consumption, with 40% of the decline coming from fertilizer plants since US and Israel launched strikes on Iran in late February.

The Middle East conflict has caused Iran to close the strait and prompted a US naval blockade, spreading through global logistics. Congestion at the Panama Canal has intensified as Asian buyers shift to US Gulf crude, with oil tankers outbidding bulk carriers for transit slots. Grain shipping rates have surged 50-60%, while wait times at the canal stretch to around 40 days as oil operators pay millions to skip queues.

Agricultural traders warn markets haven't fully priced in prolonged disruption risks. Vijay Chakravarthy at Louis Dreyfus Company noted even six more months of disruption could impact the 2027 crop cycle. Higher freight rates are pressuring US farmers already struggling to compete with lower-cost producers like Brazil, while government responses to supply concerns through reserve building could further tighten global availability and drive up prices.
