ISLAMABAD: The global economy is facing intensifying disruption as a US naval blockade of Iranian ports has sharply escalated tensions in the Gulf region, triggering fears of prolonged energy shortages, fertilizer supply constraints, and worsening food security risks across the world.
The unfolding crisis comes against the backdrop of already volatile markets since late February 2026, when geopolitical tensions in the region intensified. Since then, fertilizer prices have surged dramatically, raising concerns over the long-term stability of global agricultural production.
Urea, one of the most widely used nitrogen-based fertilizers critical for food production, rose from approximately $469–$574 per ton in late February 2026 to around $594 per ton by mid-March, before further climbing to $674–$701 per ton in early April. This represents an increase of roughly 45 percent to 75 percent within six to seven weeks, driven by rising energy costs, supply chain uncertainty, and heightened geopolitical risk in key producing regions.
Ammonia prices have also seen a sharp upward trend. From around $400–$443 per ton in early February, prices surged to nearly $600 per ton by mid-March, marking an increase of approximately 20 percent to 25 percent within just a few weeks, particularly in Middle Eastern export markets.
Analysts warn that the fertilizer market remains highly vulnerable to energy shocks, as production is heavily dependent on natural gas and petrochemical feedstocks. Any disruption in Gulf shipping routes has an immediate ripple effect on both availability and pricing.
Oil markets have also reacted strongly to the reported escalation. Brent crude rose by approximately 7 percent in a single trading session to $101.75 per barrel, after briefly touching higher levels earlier in the week. West Texas Intermediate futures also climbed to around $103.48 per barrel, reflecting heightened risk premiums. Regional benchmarks, including Dubai crude, reportedly surged to significantly higher levels, further increasing pressure on import-dependent economies.
The US Navy defines a blockade, according to its 2022 Commander’s Handbook on naval operations law, as a belligerent action aimed at preventing vessels of all states — neutral or otherwise — from entering or leaving designated ports or coastal areas controlled by an adversary. Reports suggest that such restrictions have now been applied to Iranian ports across both the Arabian Gulf and the Gulf of Oman.
Iran has responded with strong warnings, stating that no port in the Persian Gulf or Gulf of Oman would remain safe if escalation continues. Iranian military leadership has described maritime routes in the region as either “open to all or open to none,” signaling the risk of further escalation.
China has also reacted strongly to developments, emphasising that the Strait of Hormuz is a vital global energy corridor and warning that maintaining maritime stability is in the interest of the international community. Beijing has called for restraint and an immediate de-escalation, while also stressing the importance of uninterrupted trade flows.
Russia has reportedly condemned any blockade-style measures, calling them a violation of international law and warning that such actions could constitute an act of war, significantly increasing the risk of broader military escalation.
Meanwhile, global markets have responded with sharp volatility. International equities have fallen between 3 percent and 8 percent, reflecting investor concerns over rising inflation, supply chain disruptions, and the possibility of prolonged conflict.
The crisis is expected to disproportionately affect import-dependent economies such as Pakistan, India, Bangladesh, and several other developing nations, where rising energy and fertilizer costs could intensify inflation and strain food security systems.
Meanwhile, a UK government spokesperson clarified that Britain is working with France and other partners to maintain freedom of navigation and has not joined the US blockade effort. Despite international efforts to contain the situation, analysts warn that the current trajectory could deepen global economic instability, with energy disruption feeding into fertilizer inflation and potentially triggering a delayed but significant global food crisis if tensions persist.
