Iran Deal May Be Near, but UK Cost Pain Will Linger

What the proposed deal contains

Trump wrote on social media on Saturday that "final aspects and details of the Deal are currently being discussed, and will be announced shortly," as first reported by City A.M. He confirmed he had discussed terms with Gulf states and Israeli Prime Minister Benjamin Netanyahu, with the UAE and Jordan among countries pressing for a resolution.

The emerging framework, according to Axios, includes a 60-day ceasefire during which the Strait of Hormuz would reopen with no tolls imposed on commercial shipping. Iran would be permitted to resume oil sales, and the US would lift some sanctions on Iranian crude. Tehran would also be required to clear the mines it deployed in the strait during the standoff.

The nuclear dimension remains unresolved. Reports suggest Iran has agreed in principle to surrender its uranium stockpile, but an Iranian source told Reuters: "The nuclear issue will be addressed in negotiations for a final agreement and are therefore not part of the current deal." That distinction matters; it introduces execution risk that could stall later phases of any accord.

Why reopening the strait will not fix UK costs overnight

The Strait of Hormuz handles roughly 20 per cent of global oil supply, according to the International Energy Agency (IEA). The closure has lasted at least three months, and the IEA has warned of record oil drawdowns during the disruption. Even a swift reopening leaves a long tail of consequences.

First, mine clearance is not instantaneous. Chief secretary to the Prime Minister Darren Jones told Sky News that the critical question is "how the Americans and others can help to clear mines that may have been laid in the Strait of Hormuz, so that commercial shipping companies have the confidence again to be able to travel through it." Until insurers and shipping lines are satisfied the waterway is safe, vessel operators will demand elevated war-risk premiums, and some may continue routing around the Cape of Good Hope, adding days and cost to voyages.

Second, the physical supply chain does not reset like a switch. Inventories drawn down over three months of constrained flow need to be rebuilt. Refineries that switched feedstock sources will not immediately revert. Port congestion, container repositioning, and renegotiated freight contracts all take weeks or months to normalise.

Third, commodity markets price in forward expectations. Brent crude, which spiked during the closure, may ease on ceasefire news, but the futures curve will reflect residual uncertainty about whether the deal holds, whether mine clearance proceeds on schedule, and whether later-phase nuclear negotiations collapse.

For UK-based operators importing energy, raw materials, or finished goods through routes affected by the disruption, the practical implication is that input costs will remain elevated well into the second half of 2026.

The inflation and growth outlook for UK businesses

The Organisation for Economic Co-operation and Development (OECD) has projected that the UK will suffer a larger GDP hit than other G7 economies from the Hormuz disruption, according to City A.M. reporting. In a worst-case scenario, the OECD has warned that UK inflation could exceed six per cent.

That figure sits uncomfortably against the backdrop of a Bank of England rate-cutting cycle that was already proceeding cautiously. UK consumer price inflation had been trending downward through late 2025 and into early 2026, giving the Monetary Policy Committee room to ease. A renewed inflationary impulse from energy and shipping costs complicates that path. If headline CPI re-accelerates, the Bank may pause or slow further cuts, keeping borrowing costs higher for longer for businesses reliant on debt finance.

The growth picture is similarly clouded. The UK economy entered the crisis with modest momentum. A prolonged period of elevated energy costs acts as a tax on activity, compressing margins for manufacturers, logistics firms, and any business with significant fuel or freight exposure. The OECD's assessment that the UK is more vulnerable than peers reflects the country's relative energy import dependence and the structure of its trade routes.

"We've had to prepare ourselves for the domestic implications of the conflict in the Middle East on the UK economy and the sooner we are able to get to the point of de-escalation and, crucially, get the Strait of Hormuz open again for the flow of oil and trade, the better for all of us," Darren Jones told Sky News.

Sir Keir Starmer said he welcomed progress on the deal, according to City A.M., but the government's public statements have stopped short of offering specific fiscal support for businesses affected by the disruption.

What operators should be planning for now

The temptation for business leaders is to treat the ceasefire announcement as the end of the crisis. The evidence suggests otherwise. Three areas warrant particular attention.

Energy and fuel costs

Companies with significant energy exposure should assume that wholesale prices will remain above pre-crisis levels for at least three to six months after the strait reopens, reflecting inventory rebuilding and residual risk premiums. Fixed-price energy contracts entered into during the spike will lock in elevated costs regardless of spot price movements. Finance directors should model scenarios in which fuel and energy costs normalise only gradually through late 2026.

Supply-chain lead times

Importers who rerouted shipments during the closure face a period of dual disruption: existing longer-route shipments still in transit, overlapping with a resumption of strait traffic that will itself be subject to delays from mine clearance and insurance reassessments. Lead times are unlikely to return to normal before the autumn. Procurement teams should maintain buffer stock levels and keep alternative supplier relationships active rather than reverting immediately to pre-crisis arrangements.

Pricing and margin management

Input cost inflation feeds through to finished-goods pricing with a lag. Businesses that absorbed cost increases during the crisis to protect customer relationships will face pressure on margins as those costs persist. Equally, businesses that passed costs on may find customers resistant to maintaining higher prices once the headline crisis appears resolved, even if underlying costs have not yet fallen. Clear communication with customers and suppliers about the timeline for cost normalisation will be important.

The Hormuz crisis has been a stress test for UK supply chains. The deal, if it holds, removes the most acute risk. But the economic aftershocks, from inflation expectations to freight repricing to inventory cycles, will take considerably longer to dissipate than the diplomatic headlines might suggest. Planning for a protracted normalisation, rather than a clean return to the status quo, remains the prudent course.
