Brent Oil Surges Past $100 as Iran Blocks Strait of Hormuz, Sparking Market Chaos
Brent crude oil has surged above $100 per barrel, capping off one of the most volatile weeks in the history of the oil market. Investors are bracing for continued upheaval as Iran has pledged to keep the vital Strait of Hormuz effectively closed, severely disrupting global energy supplies.
Historic Market Volatility and Supply Disruption
The global oil benchmark experienced wild swings on Friday, following a dramatic 9.2% jump in the previous session. This week's price fluctuations have covered the widest range on record, highlighting the extreme uncertainty gripping the market. The International Energy Agency has warned that this supply disruption is the largest in the history of the global oil market, comparing it to major Middle East supply shocks of the 1970s.
Philip Jones-Lux, senior market analyst at Sparta Commodities, stated, "This is the most important oil supply disruption event since the 1970s." He added that while emergency reserve releases might temporarily prevent prices from reaching "stratospheric levels," the relief is likely to be short-lived.
Geopolitical Tensions and the Strait of Hormuz
The crisis centers on the Strait of Hormuz, the narrow waterway between Iran and the Arabian Peninsula that serves as a critical chokepoint for global oil shipments. Iran's new supreme leader has declared that the strait should remain closed, and reports indicate the country has begun laying mines in the channel, making passage even more perilous.
Since the conflict began on February 28, vessel traffic through the strait has slowed to a trickle. This near-halt has choked off shipments of:
- Crude oil
- Natural gas
- Refined products like diesel
The disruption is already having severe consequences, with jet fuel trading above $200 per barrel in Europe and fears mounting about a potential inflation crisis that could impact economies worldwide.
US Response and Market Implications
In response to the crisis, the United States has issued its second temporary waiver for the purchase of Russian oil, this time covering oil loaded onto vessels before March 12. This broader measure follows an earlier directive that only cleared India to increase its purchases.
US President Donald Trump has issued fresh warnings to Iran, emphasizing in a social media post that preventing Iran from obtaining nuclear weapons and being a threat to the Middle East is "of far greater interest and importance to me" than the cost of oil.
Energy Secretary Chris Wright suggested the US Navy might begin escorting tankers through the strait by the end of March, though experts remain skeptical. Aaron Stein, president of the Foreign Policy Research Institute, noted, "You cannot clear mines during active combat in a risk-free way and the Navy will not want to enter the strait. The risk is intolerable to international shipping."
Continued Market Turbulence Expected
Brent crude has swung in a range of approximately $38 this week—the most extreme movement ever recorded. These wild fluctuations have been exacerbated by financial flows from options markets to exchange-traded funds, with Brent's nearest timespread jumping by more than a dollar on Thursday alone.
Haris Khurshid, chief investment officer at Karobaar Capital LP in Chicago, predicts, "Volatility likely stays elevated until there's clarity on flows through Hormuz." He suggests a price range of "$85–$105 makes sense while the conflict is still unresolved and ongoing."
With several ships attacked this week and no signs of the war ending soon, the extreme market fluctuations are expected to continue, keeping global energy markets on edge as the world grapples with this unprecedented supply crisis.
