Oil Markets Brace for "Total Interruption" as Strait of Hormuz Traffic Halts

Crude oil prices are reacting violently to what traders fear is the “worst-case scenario” for global energy supply: a blockade of the Hormuz Strait. The geopolitical escalation has triggered significant intraday volatility across energy benchmarks.

• Brent Crude spiked over 13% intraday—its largest single-day move since March 2022—before settling around $77.51.
• WTI surged 7.3% to close at $71.94.

The Chokepoint Crisis

Digital signals indicate that oil tanker traffic through the Strait of Hormuz—a waterway responsible for 20-30% of global oil supply—has effectively flatlined. Reports confirm three vessels were attacked near the entrance to the Persian Gulf.

In response to potential targets, the IRGC has issued explicit threats to destroy regional energy infrastructure, transforming shipping risks from theoretical to imminent physical destruction.

Goldman Sachs commodities data suggests the most destructive risk profile is a “sustained total interruption,” while Bloomberg Economics estimates that a prolonged blockade could see prices gap up to $108 per barrel immediately.

Inflationary Feedback Loop

The energy shock comes at a fragile moment for central banks. With US Producer Price Index (PPI) already coming in hotter than expected, a war-driven oil spike risks unanchoring inflation expectations.

• India: Imports 90% of its oil; severe pressure on the Rupee and energy-sensitive stocks.
• China Petroleum: Shares hit an 11-year high in Shanghai as investors scramble for energy exposure.

BNP Paribas notes that traders are closely monitoring conflict duration. If the US is drawn into a ground war, the resulting oil shock could force the Federal Reserve to keep rates higher for longer.
