Oil Surges to $94 as US–Iran Tensions Escalate in the Strait of Hormuz

Brent crude jumped to $94 a barrel this week as US–Iran military exchanges in the Strait of Hormuz intensified. The US had revoked authorisation for countries to purchase Iranian oil; Iran responded by targeting commercial shipping in the 21-mile chokepoint through which 20% of global oil supply flows every day. The S&P 500 fell on Monday before recovering mid-week as Iran signalled openness to diplomacy.

Why it matters: Oil above $90 is a fundamentally different environment for inflation. UK petrol prices, home heating bills, and airline fares all follow crude with a 6–8 week lag. The Bank of England, already on hold, now faces rising energy costs just as inflation was beginning to ease.

UK CPI Falls to 2.6% in June — Third Consecutive Undershoot but Energy Risks Loom

UK consumer price inflation (CPI) fell from 2.8% to 2.6% in June, below the 2.7% forecast and the lowest reading since March 2025. This is the third consecutive month in which inflation has come in below consensus expectations. Fuel prices and food deflation drove the bulk of the downside surprise, while services inflation remains elevated at around 5.7%.

The catch: With Brent crude at $94, that fuel-price relief is already reversing. Analysts at Capital Economics estimate UK CPI could bounce back above 3% by September if oil holds at current levels. The Bank of England, meeting on 30 July, is widely expected to hold rates at 3.75% — but markets are now pricing in the possibility of a hike by early 2027.

Jamie Dimon Says Markets Are Not Pricing in the Real Risks — and He Has a Point

JPMorgan CEO Jamie Dimon told investors this week that global markets are underestimating a growing list of geopolitical and fiscal threats. With the S&P 500 near all-time highs, equity valuations imply a relatively smooth economic path — but Dimon pointed to US fiscal deficits running at 6% of GDP, geopolitical fragmentation, and still-elevated inflation as risks that are not fully reflected in prices.

In plain English: When the CEO of the world’s largest bank by market capitalisation says he is worried, it pays to understand why. Stock prices currently assume inflation falls smoothly and rates come down gently. Oil at $94 threatens both those assumptions at once.

Dimon’s Risk Checklist

🔴  US fiscal deficit running at ~6% of GDP
🔴  Middle East conflict pushing oil above $90
🔴  US–China trade fragmentation ongoing
🔴  Inflation still above target in US and UK
