The price of Brent crude oil settled above $100 per barrel for the first time since August 2022, driven by a major supply disruption in the Persian Gulf. This event, described as the largest in the history of the global oil market, was triggered by multiple vessel attacks across the Arabian Gulf, signaling a broadening of Iran's maritime disruption campaign beyond the critical Strait of Hormuz. As a result, millions of barrels of oil remain trapped, causing significant market volatility.

Market Impact and Price Movements

On March 12, Brent crude soared 9.2%, while West Texas Intermediate rose 9.7% to settle at $95.73, its highest level in almost four years. The breach of the $100 threshold for Brent is seen as a psychological milestone that could intensify political pressure on U.S. leadership to address the war and rising energy costs. Prices experienced some easing during trading following conflicting reports about the strait's status, including an Agence France-Presse report that Iran allowed some ships to cross and was not laying mines, which contrasted with earlier statements from Iran's new supreme leader that the waterway should stay closed.

International and U.S. Response

In response to the crisis, the U.S. Treasury Secretary stated the U.S. Navy will escort vessels through the strait as soon as militarily possible. Additionally, the U.S. administration plans to issue 30-day waivers to the Jones Act, a maritime law, to allow foreign tankers to help supply refiners on the East Coast with fuel from the Gulf Coast and elsewhere in the U.S. This move, along with a planned release of 172 million barrels from strategic reserves as part of a coordinated international effort, aims to calm supply fears. However, analysts caution that these are temporary fixes, with their effectiveness diminishing the longer the disruption persists.

Analyst Warnings and Broader Strain

Financial analysts issued stark warnings about the potential for further price increases. Goldman Sachs warned that oil prices could exceed the 2008 peak of $147.50 per barrel if flows through the Strait of Hormuz remain depressed through March. The disruption is exacerbating wild price swings, partly driven by financial flows from options markets and exchange-traded funds. Signs of strain are also evident in Asia, where Chinese refiners have begun canceling agreed fuel-export cargoes, including gasoline and diesel, following directives to stop signing new contracts.

Market Dynamics and Outlook

The scale of the disruption presents a significant challenge to global supply. With global crude consumption slightly above 100 million barrels per day, Persian Gulf producers have had to reduce roughly 6% of output. Analysts note that the supply risk premium continues to strengthen despite the historic strategic petroleum reserve release, indicating a deep and persistent market shock. The situation has left discretionary money managers cautious, while systematic trading funds have limited scope for further selling, creating a complex and tense market environment.
