The market is betting on a diplomatic resolution, but the intelligence community is short-selling that optimism. Whitehall sources have confirmed that UK spy chiefs believe Tehran will not capitulate to President Trump’s ultimatum, raising the spectre of a military confrontation that could send oil prices through the roof.
For weeks, the FTSE 100 has been drifting higher on hopes that a last-minute deal would avert a crisis in the Strait of Hormuz. But the latest intelligence assessments paint a more bearish picture. Iran’s leadership appears willing to ride out the storm. Their calculation is that the US is over-leveraged and that any strike would be a costly distraction from Trump’s domestic agenda. This is a game of chicken, and both sides are flooring the accelerator.
As a consequence, gilt yields are twitching. The 10-year yield is currently hovering around 1.15%, but any escalation could see a flight to safety that pushes yields lower and inverts the curve further. The Bank of England will be watching nervously. A spike in oil prices would feed through to inflation, forcing the MPC to tighten into a slowing economy. That is the nightmare scenario for the hawks.
Meanwhile, sterling is taking a hit. The currency has been under pressure from the ongoing Brexit saga, but this geopolitical risk adds another layer of volatility. The dollar is strengthening on safe-haven flows, and the pound-dollar rate is testing support levels. Capital flight is a real risk if the situation deteriorates. Investors hate uncertainty, and there is plenty of it on both sides of the Atlantic.
Fiscal responsibility is already a distant memory in Washington. The US national debt is approaching $23 trillion, and a Middle Eastern military adventure would add billions more. The Treasury will have to fund that through more borrowing, which means higher bond yields eventually. But for now, the market is more concerned about the immediate threat to oil supplies.
For the UK, the stakes are high. We import a significant portion of our crude from the region. A disruption could send petrol prices above £1.50 a litre, hammering consumer confidence. The Chancellor would have little fiscal headroom to offer relief without breaking the fiscal rules. It is a classic double whammy of stagflation.
The cynic in me says that this is all brinkmanship. Both sides have an interest in avoiding a war that nobody can afford. But the intelligence briefing suggests that the margins for error are narrow. The market is pricing in a 30% probability of a strike. That may be too low. As an investor, you have to consider tail risks. Diversify away from sectors that are exposed to the Middle East. Consider gold, the ultimate safe haven.
The bottom line is this: the clock is ticking. Trump’s deadline is a moving target, but the underlying trend is ominous. The UK intelligence community is rarely alarmist. When they say Iran will not back down, we should listen. The market is not listening closely enough.
