Oil markets were thrown into turmoil this morning following reports that the United States has launched a fresh wave of military strikes against Iranian targets. Brent crude futures spiked by nearly 5% in early trading, breaching the $80 per barrel mark as traders scrambled to price in the heightened risk of supply disruption from the Strait of Hormuz. This is the kind of geopolitical shock that sends a jolt through the financial system, and the City is now bracing for a prolonged period of volatility.
For years, I have argued that the market's tendency to discount geopolitical risk is a dangerous game. Today, that complacency has been shattered. The immediate reaction is a classic flight to safety: gold is up, gilt yields are down, and the pound is taking a hit as investors seek refuge in the dollar. But the real story here is the inflationary impulse. Higher oil prices feed directly into transport costs, manufacturing, and ultimately consumer prices. The Bank of England, already wrestling with sticky inflation, now faces a fresh headache. Rate cuts that were whispered about in Threadneedle Street may now be postponed indefinitely.
The US administration’s decision to escalate strikes against Iran is a calculated gamble. The stated aim is to cripple Iran's ability to threaten regional stability, but the market sees it differently: a risk of wider conflict that could choke off oil supplies from the Persian Gulf. The Strait of Hormuz, a chokepoint for about 20% of the world's oil, is the Kremlin-sized elephant in the room. Any disruption there would dwarf the current price spike. The fiscal implications are significant: higher petrol prices will squeeze household budgets, damping consumer spending just as the UK economy shows tentative signs of recovery.
Looking at the bond market, the 10-year gilt yield has dropped sharply as investors pile into safe-haven sovereign debt. This is a classic risk-off move. But I can't help wondering: is this rational? Central banks are still fighting inflation, and a supply-driven oil shock only adds to it. The market's flight to safety may be a temporary illusion. In the longer term, we could see stagflationary pressures, a scenario that policymakers dread. Capital flight is already evident, with emerging market currencies taking a beating. The end of the cheap oil era is a theme I keep returning to, and this crisis only reinforces that view.
The key question now is how far this goes. If the strikes are a one-off, we might see a pullback. But if this is the beginning of a sustained campaign, then $100 oil is not off the table. The City will be watching the diplomatic channels and any OPEC response with hawkish eyes. The bottom line: the geopolitical risk premium has returned with a vengeance, and for now, it's the oil bulls who are calling the shots.
