UK headline CPI rose to 3.3% in March 2026, up from 3% in February, as the Iran war’s energy shock began filtering into pump prices, freight costs, and ultimately household bills. The ceasefire Donald Trump extended indefinitely on 21 April has done nothing to reopen the Strait of Hormuz — Tehran has made clear the waterway stays closed while US Navy vessels continue intercepting Iranian tankers, and Brent crude is still trading just below $98 a barrel on the stalemate. The inflation print is the first confirmed evidence that the Middle East conflict has crossed from commodity markets into the real UK economy.
The more worrying signal sits beneath the headline. Clothing and footwear prices fell 0.8% year-on-year in March — the lowest annual rate for that month since the pandemic year of 2021 — which tells you consumers have stopped discretionary spending sharply enough to force retailers into defensive discounting. That is not cyclical caution. That is the opening phase of a second cost-of-living crisis, and it is arriving before the worst of the fuel pass-through has landed.
The Hormuz Problem Is Now a UK Domestic Problem
The crucial waterway handles close to 20% of global oil and LNG supply in normal conditions, and it is currently moving almost nothing. Every extra day of closure compounds the logistics bottleneck in ways that are no longer confined to wholesale commodity markets. Pump prices in the UK have risen steeply through March, haulage and freight costs are ratcheting up across the supply chain, and the Bank of England’s path back to its 2% target — already fragile — is now effectively blocked until the blockade ends.

SubscribeWhat makes this different from the 2022 shock is the policy constraint. The Bank cannot cut into an imported energy squeeze without losing credibility on inflation, and it cannot hold rates indefinitely without deepening the consumer slowdown already visible in the clothing data. That is the same structural trap the ECB is staring at across the channel, and it is tightening by the week.
Aviation Is the Next Domino
The sector most directly exposed is airlines. March air fares rose 10% month-on-month, with the Easter timing effect explaining most of that move — but the genuine fuel-driven increases are still ahead. Jet fuel supply chains are already under pressure severe enough that the European Commission has begun issuing contingency guidance to airlines on slot allocation and passenger rights in the event of shortages. Fuel surcharges will return to UK carriers within weeks, and the summer holiday pricing already being modelled by European operators assumes a materially worse fuel environment than consumers are currently budgeting for.
Holidaymakers who booked early on 2025 pricing assumptions face a specific risk: route cancellations if carriers cannot secure fuel contracts at viable margins. That conversation has not yet reached the public, but it is active inside the industry.
What Happens Next
The inflation trajectory from here depends almost entirely on the Strait of Hormuz, and the Strait of Hormuz depends on whether Iran’s fractured leadership can produce a unified negotiating position — which Washington does not expect for at least six weeks. Until then, UK retailers face the squeeze from both ends: cost-push pressure on input prices, and demand destruction as consumers cut discretionary spend.
The first cost-of-living crisis took two years to build. The second has taken one month.
