7 - 14 March 2026 Iran War - Weekly

Executive Summary

The Iran war escalated significantly between 7 and 14 March, evolving from a high-intensity air campaign into a wider regional conflict affecting military, maritime, and energy systems across the Middle East. U.S. and Israeli strikes expanded inside Iran while Iranian retaliation spread across multiple domains, including missile and drone attacks, proxy operations in Iraq and Lebanon, and direct pressure on Gulf shipping routes. The conflict also reached NATO-adjacent territory as Iranian ballistic missile trajectories entered Turkish airspace and were intercepted by NATO air and missile defense systems. By mid-March the war had become a geographically dispersed confrontation involving Iran, Israel, Iraq, Lebanon, Gulf states and the eastern Mediterranean. The most strategically consequential development was the disruption of global energy flows. Iran used the Strait of Hormuz as a central pressure point, severely reducing tanker traffic through the waterway that normally carries about 20% of global oil supply. Attacks on commercial vessels, naval mine threats and maritime security risks caused shipping congestion and sharply increased insurance costs. Oil markets reacted immediately, with Brent crude rising above $100 per barrel and remaining roughly 40% higher than pre-war levels. Governments and international agencies began preparing stabilization measures including strategic petroleum reserve releases, while some countries explored alternative supply routes and temporary policy adjustments to offset the shock. At the same time, the war’s strategic risks increased as energy infrastructure itself began to enter the conflict calculus. U.S. strikes on military targets at Kharg Island — Iran’s primary oil export hub handling roughly 90% of its crude exports — highlighted the vulnerability of global supply chains if energy facilities become direct targets. Iranian leaders warned that regional oil infrastructure could be attacked in response to further escalation, raising the possibility of a broader energy conflict across the Gulf. As a result, the war now represents not only a regional military confrontation but also a systemic geopolitical crisis with significant implications for global energy markets, maritime trade routes and international economic stability.
