Oil prices experienced a significant surge in early trading sessions following an announcement by the United States that it will implement a maritime blockade on Iranian ports, effective Monday, April 13, 2026. This move marks a severe escalation in the ongoing conflict that began when the US and Israel launched military operations against Iran on February 28, 2026.
Market Reactions and Price Increases
Brent crude, recognized as the international benchmark for oil prices, jumped by 7 percent to reach USD 102.29 per barrel. Meanwhile, the US benchmark, West Texas Intermediate (WTI) crude, saw an even steeper rise of 8 percent, climbing to USD 104.24 per barrel. These sharp increases highlight the volatile nature of the oil market amid geopolitical tensions.
Historical Price Fluctuations
Since the onset of the conflict, oil prices have been highly unstable. Prior to the war, Brent crude was trading at nearly USD 70 per barrel. It subsequently soared to over USD 119 at its peak level, demonstrating the profound impact of regional strife on global energy costs.
Details of the US Blockade Announcement
On Sunday, April 12, 2026, the US Central Command declared that it would enforce a maritime blockade affecting all vessels entering or exiting Iranian ports, with the measures taking effect on Monday. Commercial ships navigating the Gulf of Oman and Strait of Hormuz have been instructed to monitor maritime broadcasts and contact US naval forces if necessary.
Background and Regional Tensions
This announcement emerged against a backdrop of heightened tensions, following unresolved US-Iran talks in Islamabad and the persistent turmoil in the region. The blockade is expected to further complicate diplomatic efforts and could lead to additional disruptions in global oil supply chains.
