The Office for National Statistics confirmed today what the markets have been pricing in for weeks: the UK economy is shrinking. GDP fell 0.4% in the first quarter, a direct consequence of the escalating military conflict in Iran. The casualty list includes trade routes, energy prices, and investor confidence. The Tehran bazaar is not the only place trading has ground to a halt.
For those of us who have spent decades watching the City’s pulse, this is not a surprise. War is inflationary. It disrupts supply chains, spikes oil prices, and sends capital scurrying for safe havens. The irony, of course, is that the UK’s own fiscal house is hardly in order. Gilt yields have been volatile, the Bank of England is caught between fighting inflation and supporting growth, and the Chancellor’s budget has all the credibility of a subprime mortgage.
The oil price spike alone has added a 0.5% drag on GDP, according to our calculations. Every dollar increase in the barrel price is a tax on British consumers and businesses. The transport sector is hit first, then manufacturing, then retail. The contagion spreads like a sell-off in a crowded theatre.
But the deeper problem is capital flight. International investors are re-evaluating their exposure to UK assets. The pound has weakened 2% against the dollar this month. The FTSE 100 held up initially due to its international earners, but the domestically focused FTSE 250 is down 8%. This is not panic. It is rational repricing. The risk premium on UK debt has risen. The cost of insuring against default (CDS) has ticked up. The market is pricing in a higher probability of fiscal slippage.
Meanwhile, the government is reaching for the usual levers: fiscal stimulus, promises of infrastructure spending, and calls for monetary policy to do more. But the patient is suffering from a heart condition, not a cold. Printing money to fund spending in a war environment is a recipe for stagflation. We have seen this film before. It ends with higher interest rates and a deeper recession.
The Bank of England is in a bind. Raise rates to combat inflation, and you choke off investment. Cut rates to support growth, and you fuel inflation. The conventional wisdom is that the MPC will hold steady this month. But the market is betting on a rate cut by year-end. That is either a vote of no confidence in the economy or a bet on a ceasefire. Neither looks certain.
Let us not forget the supply side. The conflict in Iran has disrupted shipping through the Strait of Hormuz. That is a problem for global trade, but particularly for the UK, which imports a significant portion of its energy from the region. The impact on production is immediate. Factories are idling. Truck drivers are waiting for diesel. The data is anecdotal now, but it will become official soon.
The Chancellor’s spring statement was already looking optimistic. Now it looks delusional. The OBR’s fiscal headroom has evaporated. The budget deficit will widen. The government will have to borrow more, and at higher yields. That means less money for public services and more for bondholders. The politics of this are toxic.
What is the bottom line? The UK economy is in a precarious position. The conflict in Iran is an exogenous shock that exposes pre-existing vulnerabilities. We have low productivity, high debt, and a central bank with limited ammunition. The market is not your friend. It is a strict headmaster. And right now, it is handing out detentions.
The message for investors is clear: reduce exposure to UK domestic equities, increase hedging on the pound, and buy short-dated gilts if you need safety. For the government, the message is simpler: stop pretending you can fight a war, cut taxes, and balance the budget. You cannot. Choose.
History will judge this moment not by the courage of our convictions, but by the yield on our bonds. So far, the numbers are not reassuring.
