UK Real Estate and the wider implications of the Iran conflict
The US–Israeli military campaign against Iran that began on 28th February and the effective closure of the Strait of Hormuz have removed millions of barrels of daily supply from the market. On 9th March 2026, Brent crude spiked to $119.50 per barrel, the first time oil had traded above $100 since Russia’s invasion of Ukraine in 2022. Since then, prices have remained elevated: By 30 March, Brent was at $116, up more than 50% since the conflict began.
On 19th March the MPC voted unanimously to hold Bank Rate at 3.75%, having been split at 5-4 in February. While the focus is understandably on the relationship between inflation and the knock-on impacts on interest rates which in turn compress capital values, there are other considerations to take into account:
Seven Channels, One Shock
1. Macro/Monetary.
The MPC acknowledged that CPI is now expected to reach approximately 3.0% in Q2 and 3.5% by Q3, well above the 2.1% path it projected in February and flagged alertness to second-round effects from energy and food prices. OECD were as high as 4%. The Citi/YouGov survey published on 24th March showed short-term household inflation expectations surging to 5.4%, up from 3.3% in February.
While the BOE has warned “against reaching strong conclusions about us raising interest rates”, markets continue to price in hikes. Two-year gilt yields have risen to 4.60%, up ~ 97 basis points since the conflict began while ten-year gilts briefly went above 5% on 23rd March, their highest since July 2008, before pulling back to around 4.85% as Trump signaled a five-day pause in planned strikes. For real estate, the yield compression story that was expected to support capital values through the year has stalled, and purchasers and vendors alike will need to be prepared to be more flexible.
The risk premium on UK debt relative to European peers tells its own story. Ten-year gilts now yield approximately 4.9%, compared with 3.8% for French OATs and 3.1% for German Bunds, a spread of around 180 bps over Germany and 110 over France. While all three have risen sharply, the UK’s premium has held steady or widened slightly. Decomposing that premium is instructive. Five-year credit default swap spreads which price sovereign credit risk put the UK at roughly 22 basis points, compared with around 10bp for Germany and, notably, 34bp for France.
In other words, the market sees France as a greater fiscal risk than Britain. Yet French OATs still yield more than a percentage point less than gilts. The gap is almost entirely inflation risk: UK breakeven inflation rates have surged above 3%, reflecting the market’s view that Britain’s energy import dependence and sticky domestic price pressures leave it more exposed to a prolonged shock than the eurozone core.
For homeowners, the mortgage market has tightened sharply since the MPC's decision to hold rates. Average two-year fixed mortgage rates have risen to 5.56%, up from 4.83% at the start of March, with five-year fixes close behind at 5.54%. More than 1,700 products have been withdrawn from the market since 9th March, with some lenders pulling their entire range of new deals, representing a significant contraction in borrower choice.
2. Occupier Cost.
Energy is the single largest operating expense across real estate. UK wholesale gas prices surged approximately 70% in a single week. For occupiers on variable energy contracts, this is an immediate margin hit that will feed through to leasing decisions, renewal negotiations, and space requirements. Businesses already operating on thin margins face a direct threat to their ability to sustain current rental
commitments. For those locked into long-term contracts, there are cost advantages. The flash UK composite PMI fell to 51.0 in March from 53.7 in February, a six-month low; the manufacturing input cost index surged to 70.2 from 56.0, the sharpest monthly increase since 1992. Business outlook fell to the weakest since June 2025.
3. Construction Cost.
Energy-linked materials including steel, cement, glass and diesel will see upward pressure with a 3-6 month lag. During the 2022 energy crisis, construction input costs remained approximately 40% above pre-pandemic levels. Development viability, already challenging in many UK markets, faces another headwind.
4. Petrodollar Recycling.
When oil prices are high, Gulf capital flows into global real estate particularly prime offices in London, and other major cities. This time, capital that might otherwise have been recycled into European commercial property is being redirected to manage domestic economic and geopolitical priorities. The escalation since early March, South Pars gas field strikes, the Iraq force majeure, and the continued closure of the Strait only deepens the diversion of Gulf capital toward domestic priorities.
The counter to that is that a source of competition for talent and capital has now highlighted the UK’s status as a relative safe haven. The UK’s rule-of-law stability, deep capital markets, and transparent legal system become relatively more attractive when capital needs a home outside the region.
5. Energy Geography.
The UK already has the highest industrial electricity prices in the developed world, 81% more than France for comparable factory facilities. UK energy-intensive industry output is at a 35-year low, down 33.6% since 2021. This crisis amplifies an existing structural disadvantage that is reshaping industrial property demand across regions. Manufacturers weighing location decisions will factor in the UK’s energy cost premium and limited storage capacity.
6. Green Premium Acceleration.
Every energy price spike widens the performance gap between efficient and inefficient buildings. An EPC A-rated office with on-site solar and heat pumps is functionally insulated from this shock. A gas-heated, poorly insulated EPC D asset just became a lot more expensive to operate. The ‘brown discount’ grows with every spike, and this crisis makes the economic case for energy-efficient buildings unambiguous not as a matter of ESG compliance, but as a fundamental operating cost and risk management concern.
7. Carbon Compounding.
Carbon pricing mechanisms - the UK Emissions Trading Scheme and Carbon Price Support amplify energy costs. Higher gas prices mean higher electricity costs, which in turn mean higher carbon costs per unit of energy consumed. This compounding effect is barely reflected in current pricing. The Iran crisis is a reminder that carbon exposure is not a future risk to be modelled. It is a current cost amplifier.
What This Means for Investors and Occupiers
The MPC’s unanimous hold and the Bank’s upwardly revised inflation path suggest the Committee is determined not to add monetary tightening to an energy-driven slowdown but equally, it has no room to ease. The risk is deadlock.
The UK is not uniquely exposed by any stretch of the imagination, but energy import levels mean that it is exposed to this crisis. It imports approximately 40% of its oil and up to 60% of its natural gas, and holds only 12 days of gas storage compared with Germany’s 90 days and France’s 100-plus. It entered this crisis with inflation already sticky at 3%, and with inflation likely to rise further, the BOE has a difficult tightrope to walk even if the conflict is short lived.
For investors: The next inflection point is the May MPC meeting and whether wage and services data force the Committee’s hand. Bid–ask spreads that were narrowing may re-open. But there will be opportunities for well capitalised buyers; energy-efficient assets become relatively more attractive, and once gilts stabilise, bonds and property could both offer value.
For occupiers: Energy cost risk has just moved from a line item in the sustainability report to a board-level strategic concern. Businesses that have already invested in energy efficiency, on-site generation, or long-term fixed energy contracts are already insulated. This crisis makes the economic case for net-zero buildings unambiguous. While not currently on the horizon, this conflict will pass but the structural relationship between energy and property will outlast it.
