The City woke this morning to the smell of burning crude. Brent futures have plummeted by 12% in early trading, the sharpest single-day decline since the 2020 Saudi price war. The trigger? Rumours from Washington that a nuclear deal with Tehran is imminent, potentially unleashing 1.5 million barrels per day onto an already glutted market. British energy giants are scrambling to hedge their bets as the bottom falls out of the oil price.
For the FTSE 100's oil majors, this is a brutal reminder that geopolitical risk cuts both ways. BP and Shell saw their shares drop 4% and 3.5% respectively by midday. The market is pricing in a scenario where Iranian sanctions are lifted, and that means a flood of supply that OPEC+ cannot easily offset. The cartel's existing production cuts look like a sticking plaster on a haemorrhage. The irony is not lost on those who remember the 2015 Iran deal; when sanctions were lifted, it took months to ramp up production. This time, the infrastructure is ready, and the Iranians are desperate for hard currency.
But the real story is not just about crude. It is about the fiscal fallout for the UK Treasury. Lower oil prices ease the cost of living crisis, and that is good news for Rishi Sunak's inflation targets. The November CPI print, due next week, might show a sharper decline than expected as petrol prices fall. The Bank of England will be watching closely. A sustained drop in energy costs could give them room to hold rates, or even cut, earlier than anticipated. Gilt yields have already retreated 10 basis points on the news, reflecting lower inflation expectations.
Yet the market is not celebrating. The volatility is a reminder that energy transition capital is flighty. The pivot to renewables, so loudly touted by British energy firms, looks less urgent when oil is cheap. Shell's recent decision to slow down its renewable investments suddenly seems prescient. The prospect of cheap oil for years to come will test the resolve of ESG investors. If the Iran deal goes through, the green premium will look increasingly expensive.
Capital flight is the unspoken fear. The sudden drop in oil prices could trigger a rush out of energy stocks, but where does that money go? Into gilts? Gold? Or out of the UK entirely? The pound is down 0.8% against the dollar today, as traders price in lower inflation and potentially lower interest rates. A weaker sterling is good for exporters but bad for inflation, and the Bank will not want to see a repeat of last year's sterling crisis.
The bottom line is this: the US-Iran oil hopes are a double-edged sword. For consumers, it is a reprieve. For the UK's energy sector, it is a strategic pivot point. The firms that survive will be those that did not bet the farm on $100 oil. The market is now pricing in a new equilibrium, and it looks quite a bit lower than we thought a month ago. Buckle up. The volatility is just beginning.
