On mornings like these, a certain silence, or more accurately, a held breath, descends upon the City of London. As traders arrive, they are already perusing the Gulf’s overnight headlines. Half of the desks at the LSE have already decided that the day will be ugly by the time the opening bell rings. Before anyone had finished their coffee, the FTSE 100 was predicted to open down about 54 points on Thursday, and Brent crude was once again rising above $103 per barrel. Markets may be beginning to factor in something worse than a breakdown in the ceasefire. They are accounting for the possibility that the ceasefire was never truly in place in the first place.
Washington’s official position is that the cease-fire with Iran has been “extended indefinitely.” That language sounds almost ridiculous on the water. This week alone, Iran has fired on three ships and taken two of them in the vicinity of the Strait of Hormuz. Tankers flying the Iranian flag are being intercepted by CENTCOM as far away as the coast of India, Malaysia, and Sri Lanka. According to reports, Senator Lindsey Graham has cautioned that the blockade “could become global soon”—a statement that sounds different when you’re looking at the FTSE chart and witnessing the hourly rise in Gulf shipping insurance premiums. While strolling around Canary Wharf, there’s a feeling that the serenity is unbelievable.

The odd thing is that Britain’s own economic data can be surprisingly stubborn at times. The UK PMI Manufacturing Index recently reached a 47-month high of 53.6, which is more in line with a country that is quietly recovering than one that is on the verge of a recession. Public borrowing fell short of expectations. Optimism for services is growing. However, if you ask anyone currently in charge of a mid-sized British company, the topic of energy bills will come up in a matter of minutes. The current price of a 55-liter gas tank is approximately £86.50, which is more than £10 more than it was in February. Families experience that kind of number before economists do.
The strange bright spot of the day was L’Oréal’s 8% increase in Paris on Thursday. This is the fastest quarterly growth in two years for a company that sells lipstick and serums while warships traverse the Persian Gulf. The contradiction is difficult to ignore. In contrast, consumer confidence in the UK is still at its lowest point ever, -53. According to Helen Dickinson of the BRC, uncertainty increases with the duration of volatility. That is accurate, but it almost minimizes the situation.

WH Smith recently cut its profit forecast in half, suspended its dividend, and directly blamed the disruption caused by jet fuel. With 89% buy trades, Wizz Air is the most purchased stock on Interactive Investor. Retail traders are either more courageous than the rest of us or they see things that institutions do not.
It’s the little details that stick with me as I watch this play out. In the heartlands of Labour, the Reform UK steel pitch is being delivered. Everyone wants AI hardware, which is why Raspberry Pi is up 74% year over year. As scam losses mount, Experian discreetly launches a fraud tool targeted at SMEs. Almost everyone is treating the Bank of England’s decision next week as a cliffhanger, despite the fact that no central bank can actually set oil prices at gunpoint. There is “no time pressure” on the Iran ceasefire, Trump told Fox News. Perhaps not for him. The only thing that exists for a London trader watching Brent flicker green once more at 7:40 in the morning is time pressure.
