The sabre-rattling in the Strait of Hormuz has finally landed on British forecourts. With Royal Navy warships placed on standby, the market is pricing in a risk premium that will sting every household. Brent crude has spiked 8% overnight, and diesel at the pump is already climbing. This is not merely a geopolitical inconvenience. It is a direct tax on economic activity, levied by hostile actors and amplified by a decade of under-investment in domestic energy security.
Let us be clear about the mechanics. The Strait of Hormuz handles about 20% of global oil transit. A blockade, even a partial one, sends shivers through the futures curve. Speculators are piling in, and the backwardation we saw last week has flipped into steep contango. That means storage becomes profitable, which means more barrels are taken off the market. The result? Higher spot prices, immediately.
For Britain, the timing could not be worse. Inflation is stubbornly above target, hovering around 3.2%. The Bank of England is walking a tightrope between taming price pressures and not choking off growth. A sustained fuel price surge will feed directly into core inflation, forcing the Monetary Policy Committee to hold rates higher for longer. That, in turn, will punish the housing market and squeeze corporate margins. The government’s fiscal headroom, already thin, will evaporate. Gilt yields are already creeping up, and the pound is taking a hit. Capital flight is a real risk if this escalates.
The deployment of Royal Navy vessels is a necessary signal, but it is not a solution. It buys time, but it does not produce a single barrel. The underlying issue is that Britain, like much of Europe, has outsourced its energy security to unstable regions. North Sea production is in terminal decline, and the transition to renewables is not yet at scale. Until that changes, we are hostages to fortune.
There are some calling for a release of strategic petroleum reserves. That would provide a short-term fix, but it is a band-aid on a bullet wound. The reserves are meant for supply disruptions, not to manage price spikes for political expediency. Moreover, coordinated releases require American buy-in, and Washington has its own domestic pressures.
What should investors do? Trim exposure to cyclical stocks. Airlines, haulage, and any sector with high fuel costs will be under pressure. Energy stocks will benefit in the short term, but the volatility makes them a risky hold. Consider inflation-linked gilts, though the real yield is still negative. Hard assets like gold may offer a hedge, but do not expect a smooth ride.
The bottom line: this is a market-driven crisis that will test the resilience of the British economy. The government must focus on two things. First, ensuring the safe passage of tankers through the Strait. Second, accelerating domestic energy production and storage. Anything less is fiscal folly.
As always, I will be watching the yield curve. If the 2-year to 10-year spread widens further, that is a vote of no confidence in the government’s ability to manage this crisis. For now, brace for impact.
