Oil Prices Breach $100 Barrier as Iran War Chokes Global Supply Route

Brent crude oil prices remain firmly above $100 per barrel, with intraday spikes hitting $106.18 on March 16, according to Reuters and CNBC data.

The surge — up roughly 40-50% since late February — stems directly from Iran’s continued control and threats over the Strait of Hormuz, the narrow waterway that handles nearly one-fifth of global seaborne oil trade.

Iranian officials have repeatedly warned of further escalation, including potential closure that could push prices toward $200 per barrel in worst-case scenarios.

The ongoing US-Israel-Iran conflict, which intensified with strikes in late February, has already caused shipping delays and forced tankers to reroute at higher costs. Global energy markets reacted sharply on March 16 when news of fresh infrastructure attacks broke.

The ripple effects are immediate and widespread. Gasoline prices in the United States have climbed more than 21% to an average $3.63 per gallon.

Analysts at the International Energy Agency note that sustained high energy costs threaten to reverse recent disinflation trends and add upward pressure on transportation, manufacturing, and consumer goods worldwide.

Central banks are monitoring the situation closely, aware that prolonged volatility could force tighter monetary policy even as other inflation drivers ease. Traders and businesses are now pricing in extended geopolitical risk, with alternative supply routes proving insufficient to offset the disruption.

As of March 17, futures contracts show no immediate relief in sight unless diplomatic progress materializes.
