US–Iran Ceasefire Briefly Sinks Oil Futures but UK Pump Prices Keep Climbing

The whiplash echoes the 1973 Arab oil embargo, when a geopolitical choke-point decision quadrupled prices in weeks, and the 1980–88 Iran–Iraq War, during which Hormuz tanker wars repeatedly rattled markets despite short-lived truces. Today’s episode underscores two structural realities: first, that a single 21-mile strait still governs a fifth of global oil, and second, that retail fuel markets pass cost spikes to consumers far faster than they rebate windfalls—a pattern regulators term “rocket and feather.” The ceasefire’s narrow window and social-media diplomacy highlight the fragility of energy security in an era when algorithmic trading amplifies every headline yet refining and tax regimes slow price relief. Over a 100-year arc, this moment will be a footnote unless it accelerates diversification away from oil; if not, it is simply the latest reminder that dependence on a century-old fossil infrastructure keeps economies hostage to the politics of a few shipping lanes.
