Roughly 30% of global urea exports are currently stalled, unable to leave the Persian Gulf region due to Iran's intermittent closure of the Strait of Hormuz. This disruption directly impacts farmers worldwide, potentially increasing fertilizer costs for millions, a direct blow to critical global supply chains.
Iran announced a complete closure of the Strait of Hormuz to all commercial ships. Yet, it has intermittently allowed some vessels through, but only for significant tolls. This tactic complicates international shipping, turning a vital waterway into a transactional chokepoint.
Based on Iran's pattern of partial closures, military posturing, and negotiation, the Strait of Hormuz will likely remain a tool for strategic leverage. Expect unpredictable disruptions and conditional passage, rather than a return to stable, unimpeded trade in the short term.
Iran's Strategic Calculus Behind the Disruptions
Iran's state media announced forces fired live missiles toward the Strait of Hormuz, closing it for several hours for "safety and maritime concerns," according to pbs. These actions aren't just about security; they confirm Iran's strategy to assert sovereignty and respond to perceived threats, simultaneously creating a lucrative pretext for collecting tolls from passing vessels.
A Chronology of Closures and Escalations
Iran's actions in the Strait of Hormuz are directly tied to geopolitical events. For instance, following US-Israel strikes on Tehran, Iran swiftly closed the passage to shipping traffic on February 28, an escalation reported by Al Jazeera.
- February 28: Iran closed the passage to shipping traffic following US-Israel strikes on Tehran, according to Al Jazeera.
- Later in 2026: Iran announced the complete closure of the Strait of Hormuz to all oil tankers and commercial ships. This was in response to recent US strikes, according to Al Jazeera.
