Quick Summary
- Brent crude has surged beyond the $100 per barrel threshold following Iran’s commitment to maintain closure of the Strait of Hormuz.
- International Energy Agency officials declared this an unprecedented supply crisis and authorized the deployment of 400 million barrels from strategic petroleum reserves.
- Washington granted a limited exemption permitting select nations to purchase Russian crude oil, effective through April 11.
- Intelligence reports indicate Iran has started deploying naval mines throughout the strait, escalating risks for maritime vessels.
- Military officials suggest US Navy convoy operations could commence by late March, though analysts remain skeptical about crisis resolution.
Global energy markets experienced dramatic upheaval this week as Brent crude oil climbed past the $100 per barrel mark, driven by Iran’s declaration to maintain its blockade of the strategically vital Strait of Hormuz.

The dramatic price escalation comes amid unprecedented market volatility. West Texas Intermediate approached $97 per barrel, with both major oil benchmarks experiencing price fluctuations unseen since the COVID-19 pandemic era.
In his inaugural public address since assuming leadership from his late father, Iran’s new supreme leader Mojtaba Khamenei affirmed the nation’s determination to maintain the shipping blockade.
The Strait of Hormuz represents a critical chokepoint situated between Iranian and Omani territory. Approximately 20% of global petroleum supplies transit through this narrow passage. Since hostilities between the US-Israel coalition and Iran erupted on February 28, maritime traffic through the region has virtually ceased.
Officials at the International Energy Agency characterized the situation as the most severe supply shortage in petroleum market records. The organization committed to deploying 400 million barrels from strategic stockpiles maintained by participating nations.
According to reporting by the New York Times citing American intelligence sources, Iranian forces have initiated mine-laying operations within the strait. This development substantially increases hazards for commercial vessels attempting passage.
Energy Secretary Chris Wright indicated that Naval escort missions for commercial tankers could begin before month’s end. However, administration officials retracted earlier social media claims suggesting such operations had already commenced.
Washington Temporarily Lifts Russian Oil Restrictions
In an effort to alleviate market strain, the Treasury Department announced a limited exemption allowing designated countries to accept Russian petroleum shipments that departed ports prior to March 12. This temporary measure expires on April 11.
Treasury Secretary Scott Bessent characterized the decision as necessary for global energy market stabilization. Russian officials estimate approximately 100 million barrels remain aboard vessels currently at sea.
London declined to implement similar sanction relief. British energy minister Michael Shanks expressed concerns that such measures could provide Moscow with additional resources for military operations.
French leader Emmanuel Macron rejected the rationale, stating the Hormuz situation doesn’t warrant Russian sanction relief. Ukrainian President Zelensky characterized the American decision as a “serious blow” to Ukrainian interests.
Financial Market Reactions
Stock markets experienced declines throughout the week as petroleum prices rallied. The extreme volatility has been amplified by derivatives trading and commodity fund activity.
WTI crude demonstrated a trading range spanning approximately $43 during the week, representing the widest price band since the brief negative pricing episode during the pandemic. Brent exhibited comparable volatility with roughly $38 between extremes.
Asian economies, particularly dependent on Gulf region supplies, have implemented emergency measures. Japan, South Korea, and Thailand introduced fuel price controls. The Philippines, which sources nearly 95% of its crude from Middle Eastern suppliers, mandated shortened work weeks for government employees to reduce consumption.
Market analysts project a sustained trading range between $85 and $105 throughout the ongoing conflict. While the strategic reserve release may provide near-term relief, experts caution it represents an insufficient long-term solution.
President Trump stated via social media that preventing Iranian nuclear weapons development takes precedence over energy price considerations.
