TLDR

- In response to what it calls the most severe oil supply crisis ever recorded, the IEA has authorized the release of 400 million barrels from strategic stockpiles.
- Washington has granted temporary sanctions relief permitting select nations to purchase Russian crude, with the exemption lasting through April 11.
- Intelligence reports indicate Iran has started deploying naval mines throughout the strait, significantly elevating risks for maritime traffic.
- Plans are underway for US Naval forces to provide convoy protection for tankers by month’s end, though analysts remain skeptical about its effectiveness.
Global energy markets experienced severe turbulence this week as Brent crude oil climbed beyond the $100 per barrel mark, driven by Iran’s determination to maintain its closure of the Strait of Hormuz, while equity markets tumbled in response.

The dramatic price increase comes amid exceptional market volatility not witnessed in recent years. West Texas Intermediate approached $97 per barrel, with both major benchmarks experiencing price fluctuations reminiscent of pandemic-era chaos.
Mojtaba Khamenei, Iran’s newly appointed supreme leader, delivered his inaugural public remarks since assuming power from his father. His statement emphasized Iran’s resolve to prevent shipping traffic through the strategic waterway.
The Strait of Hormuz represents a critical chokepoint—a slim passage separating Iran from Oman through which approximately 20% of global petroleum supplies transit. Maritime activity has ground to a virtual standstill since hostilities between the US-Israel alliance and Iran erupted on February 28.
Describing the situation as unprecedented, the International Energy Agency has coordinated what represents the largest-ever coordinated release from strategic petroleum reserves—a staggering 400 million barrels from member nation stockpiles.
According to reporting by the New York Times based on US intelligence sources, Iranian forces have commenced mine-laying operations throughout the strait. This development substantially increases hazards for any vessels attempting passage.
Energy Secretary Chris Wright indicated that naval escort operations for commercial tankers could commence before March concludes. However, the administration retreated from earlier social media claims suggesting convoy operations had already successfully transported a tanker through the waterway.
US Eases Russia Oil Sanctions
Seeking to relieve market tensions, the Treasury Department announced a limited sanctions waiver permitting designated nations to accept delivery of Russian petroleum that had already been loaded aboard vessels prior to March 12. This exemption remains valid through April 11.
Treasury Secretary Scott Bessent characterized the decision as necessary for global energy market stabilization. Moscow reported approximately 100 million barrels of crude currently aboard tankers in international waters.
The United Kingdom declined to mirror America’s approach to Russian sanctions relief. British energy minister Michael Shanks expressed concern that such measures could provide Russia with additional resources to finance its military operations.
French President Emmanuel Macron voiced opposition as well, arguing that the Hormuz situation doesn’t warrant removing Russian sanctions. Ukrainian President Zelensky characterized the American action as a “serious blow” to Ukrainian interests.
Markets and Prices
Stock markets experienced declines throughout the week as petroleum prices escalated. The extreme volatility has been amplified by derivatives trading and ETF-related activity.
WTI crude witnessed intraday trading ranges spanning approximately $43 this week—the most extreme volatility since oil futures briefly turned negative during the pandemic crisis. Brent experienced swings of roughly $38 per barrel.
Asian economies, heavily dependent on Middle Eastern crude imports, have responded aggressively. Japan, South Korea, and Thailand have implemented gasoline price controls. The Philippines, which sources nearly 95% of its crude from the Gulf region, has mandated a four-day workweek for government employees to reduce fuel consumption.
Market analysts project a likely trading range between $85 and $105 per barrel for the duration of the conflict. While the IEA’s reserve deployment may provide temporary market relief, experts caution it represents an insufficient solution for achieving long-term stability.
President Trump stated via social media that denying Iran nuclear weapons capabilities remained his priority, superseding concerns about crude oil pricing.
