Brent crude oil has surged to $90 per barrel, driven by escalating U.S.-Iran tensions threatening shipments through the critical Strait of Hormuz. This marks a significant jump from June's $68 level and represents the highest price since November 2022, with a sharp weekly gain.

The price spike is renewing inflation pressures across Europe and the United States. This development complicates potential interest rate decisions by the Federal Reserve and the Bank of England.

Market impacts are already visible. The FTSE 100 trades near 10,440, with energy stocks like BP and Shell gaining. Conversely, banking and travel sectors face downward pressure from inflation concerns.

Analysts note the price action aligns with scenarios of heightened inflation. Prediction markets now price a 15% probability of crude oil reaching a new all-time high by year-end.

The situation remains fluid. Markets will closely watch for further U.S.-Iran escalation and upcoming central bank meetings. Any OPEC production shifts or geopolitical supply disruptions could significantly influence crude oil pricing.
