The Iran conflict and the UK Real Estate market

The conflict involving Iran and subsequent disruption to the Strait of Hormuz and across the wider Middle East, sent a fresh wave of uncertainty through global financial markets, and UK real estate is not immune. For developers, investors and lenders already navigating a post-rate-shock landscape, the compounding pressures are material and the decisions being made right now will define returns for years to come.

The most immediate transmission mechanism is financing cost. SONIA-linked swap rates, which underpin the vast majority of UK commercial real estate debt, tell a clear story. The 1-year rate sits at 4.10%, the 2-year at 4.18% and the 5-year at 4.20%, with the curve climbing further out to 4.44% at 10 years and 4.83% at 30 years. The remarkably flat curve of a year ago has given way to a steeper one: the very short end has edged down over the past month as markets allow for the possibility of de-escalation, but every tenor now sits materially higher than it did twelve months ago, reflecting a market that has quietly but firmly pushed back its expectations of meaningful rate relief. Development appraisals that appeared viable earlier this year are being stress-tested against this reality, and in many cases, they are not passing.

Rate cuts remain on the table, but the timing has shifted markedly. The Bank of England has held Bank Rate at 3.75% through its recent meetings, with the next decision due on 18 June 2026. Inflation has climbed back to 3.3% – above the 2% target and expected to rise further this year – as the war in the Middle East drives up energy costs, and the Bank has explicitly warned of the inflationary risk the conflict poses. With that backdrop complicating the Bank’s path, borrowers should plan on the current rate environment persisting well into 2027 and structure their debt accordingly.

On the ground, the contractor market is adding its own layer of complexity. Build cost inflation, which had begun to moderate, is showing signs of re-acceleration driven by energy-linked material costs. More strikingly, we are seeing contractors on some sites beginning to hoard materials - a tell-tale sign that supply chain anxiety is returning and that confidence in forward pricing is fragile. Financial pressures among mid-tier contractors remain acute, with many carrying fixed-price contracts tendered in a lower-cost environment. Major contractors are increasingly selective about what they will price, favouring clients with strong covenant, proven delivery records, and committed funding in place. Speculative schemes with uncertain debt structures are struggling to attract competitive tender returns at all.

The ripple effects extend well beyond the construction site. Diesel and fuel costs, directly linked to the conflict-driven spike in crude prices – Brent is trading around $94 a barrel, roughly 40% higher than a year ago, with disruption to the Strait of Hormuz keeping supply fragile and prices volatile – are compressing margins for the SMEs that form the backbone of most real estate supply chains (haulage firms, specialist subcontractors, fit-out suppliers and plant hire operators). Many of these businesses operate on thin margins with limited hedging capacity, meaning even a sustained 10-15% increase in fuel costs can turn a profitable contract into a loss-making one. The knock-on effect is twofold: lead times are stretching as smaller operators ration deliveries, and pricing volatility is making it near-impossible for contractors to hold fixed quotes beyond 30 days. For developers, this translates directly into programme risk and cost uncertainty, two variables that lenders are scrutinising more closely than ever.

Investors must now price sovereign geopolitical risk as a permanent structural factor driving supply shocks and a fracturing global economy. A pronounced flight to safety is shifting capital away from energy-reliant European sectors and towards established, energy-independent core markets such as the US. To combat elevated debt costs in traditional commercial real estate, investors are securing defensive growth through living, logistics, and data-centre infrastructure.

It would be remiss to ignore the other side of the ledger. Diplomatic efforts to bring the conflict to a close are under way, with US-led talks aimed at halting hostilities and reopening the Strait of Hormuz, and even tentative signs of progress have been enough to pull oil prices back from their recent highs. A durable settlement would ease energy costs, take pressure off swap rates and unwind much of the risk premium currently weighing on appraisals. But the path remains fragile: no agreement has been signed, sporadic clashes continue, and a single setback can reverse a week of gains in a single session. Prudent planning means treating de-escalation as a welcome upside scenario rather than a base case to be relied upon

This is not a moment for paralysis, but it is absolutely a moment for precision. Capital deployed thoughtfully into assets with strong occupational demand, realistic debt structures, and resilient build programmes will find opportunity in the dislocation. Poorly structured deals, however, face a genuinely difficult path.

At Kingswood, we are working closely with clients to reappraise assumptions, stress-test appraisals against current financing realities, and identify where value genuinely exists in this environment. If you are considering a transaction or development commitment in the current climate, the right advice has rarely mattered more.

We would welcome the conversation
