House prices fell in the UK for the first time this year in May, as rising interest rates triggered by the war in Iran hurt homebuyer demand.
The price of the average UK home dropped 0.6% in May compared with the month before, according to the lender Nationwide.
The typical house price was 1.7% higher than the same point last year, at £278,024. However, that marked a slowdown from an annual growth rate of 3% in April.
Robert Gardner, the chief economist at Nationwide, said a “loss of momentum was to be expected” given uncertainty caused by conflict in the Middle East and the subsequent rise in energy prices and market interest rates.
Mortgage rates have broadly risen across the market in recent months. The average two-year fixed rate was 5.68% at the end of May, while the average five-year fix was 5.63%, according to the financial data provider Moneyfacts.
Tom Bill, a researcher at the estate agent Knight Frank, said Nationwide’s figures showed the housing market was slowing down “at precisely the time of year when you would expect momentum to be building”.
“There won’t be a cliff-edge moment, but the impact of higher borrowing costs will erode spending power and squeeze house prices this year as mortgage rates agreed before the Middle East conflict gradually disappear,” he said.
The estate agent Savills has forecast that house prices will fall this year owing to rising mortgage rates.
It said the impact of war in the Middle East had “fundamentally changed” its outlook for the UK property market, predicting that average house prices will fall 2% this year, compared with its previous expectation of a 2% rise.
But Gardner added that, while market interest rates had risen in recent months, “the impact on affordability has so far been modest.”
“Swap rates, which underpin fixed‑rate mortgage pricing, remain well below the highs reached in 2023 and are broadly in line with levels prevailing in 2024, implying only a partial reversal of earlier gains,” he said.
“This provides some confidence that, if the latest shock passes relatively quickly, and energy prices normalise in the quarters ahead, any near-term softening in the housing market will also prove short lived.”
Martin Beck, the chief economist at WPI Strategy, said: “Even if mortgage rates edge lower, the market remains vulnerable.
“Affordability is still stretched, mortgage repayments absorb a historically large share of household incomes, and a weakening labour market would pose a much greater threat to house prices than interest rates alone.”
Last week Andrew Bailey, the governor of the Bank of England, said the central bank was in no rush to raise interest rates while the outcome of the Iran war remains uncertain and the UK’s economic growth remained weak. The Bank’s monetary policy committee last voted in April to keep its key interest rate on hold at 3.75%.
Four leading AI models discuss this article
"A single month of -0.6% decline amid geopolitical noise doesn't confirm a bear case; the real test is whether mortgage rates stabilize or continue climbing over the next 2-3 quarters."
The article frames a -0.6% MoM decline as a turning point, but the data is murkier than presented. YoY growth remains positive at 1.7% despite rate headwinds—swap rates are still below 2023 peaks, so affordability hasn't actually deteriorated materially yet. The real risk isn't the May dip; it's whether the 'shock passes quickly' as Gardner hopes. If Iran tensions persist, energy prices stay elevated, and swap rates don't normalize, then Savills' -2% forecast becomes credible. But the article conflates geopolitical uncertainty with structural demand destruction—they're not the same. The BoE's hold at 3.75% and weak growth backdrop actually *support* prices if rates stay flat. The cliff-edge risk is real, but we're not there yet.
Gardner's reassurance that swap rates remain 'well below 2023 highs' ignores that 2023 was a shock year—the relevant comparison is 2022 or early 2024 norms, where rates were lower. If current levels persist, the cumulative erosion of affordability will compound faster than the article suggests.
"Higher-for-longer mortgage rates will squeeze UK house prices more than the article's 'short-lived' softening narrative suggests, given stretched affordability."
UK housing faces near-term pressure as 0.6% MoM price drop and Savills' revised -2% 2025 forecast reflect higher mortgage rates (5.68% two-year fix) triggered by Iran-related energy and rate spikes. This hits at peak season, with pre-conflict fixed deals rolling off and eroding buyer power. Gardner notes swap rates remain below 2023 peaks and affordability impact modest so far, yet Beck flags stretched incomes and labor-market risk as larger threats. BoE's 3.75% hold signals caution amid weak growth, implying limited near-term rebound unless conflict resolves fast.
If the Iran conflict de-escalates within months and energy prices normalize, swap rates could fall back toward 2024 levels, reversing the modest affordability hit and limiting any price decline to a brief pause rather than the sustained 2% drop now priced in.
"The UK housing market is transitioning from a period of interest-rate-driven growth to a period of structural affordability-driven contraction."
The 0.6% monthly dip is a classic 'affordability wall' signal. While the article frames this as a reaction to geopolitical shocks, the structural issue is that 5.6% mortgage rates are incompatible with current UK house price-to-earnings ratios, which remain near historical peaks. The market is currently pricing in a 'soft landing' based on the hope of central bank rate cuts, but this ignores the sticky nature of UK wage inflation. If the Bank of England holds rates at 3.75%—or higher—to combat energy-driven inflation, we are likely looking at a multi-year stagnation in real terms, rather than a quick recovery. Exposure to UK housebuilders like Persimmon (PSN) or Taylor Wimpey (TW.) remains high-risk.
The case against this is that the UK housing market suffers from a chronic structural undersupply, which acts as a floor for prices regardless of interest rate volatility.
"Near-term UK house prices are likely to drift lower as rates stay high, but the downside is contingent on rate and energy-price trajectories; a faster-than-expected peak or cuts could arrest the slide quickly."
May's 0.6% monthly drop aligns with a broader slowdown, but the data is noisy and seasonally vulnerable. The real driver is affordability under a high-rate regime, not a one-off shock. The article underplays regional splits, the lagged effect of mortgage resets, and the potential for rental demand and supply constraints to cushion or prolong the cycle. Missing context includes the pace of wage growth, job market resilience, the shape of the BoE's policy path, and how swap rates evolve as energy prices stabilise. A scenario where rates peak or energy costs normalise could materially alter the trajectory, even if May softness persists in the near term.
If energy and swap rates stabilise or improve sooner than expected and wages hold up, fixed-rate mortgages could start to fall, reviving demand and limiting further price falls; a policy pivot or fiscal relief could also blunt the downside.
"Undersupply floors prices but doesn't protect transaction volumes—housebuilders face earnings compression even if nominal prices hold."
Gemini flags the price-to-earnings ratio correctly, but conflates two separate problems. Undersupply does act as a floor—but only if *demand* holds. A 5.6% mortgage rate environment with sticky wage inflation doesn't just compress multiples; it destroys marginal buyer cohorts entirely. Undersupply prevents collapse, not stagnation avoidance. The housebuilder exposure risk is real, but the mechanism is volume contraction, not price capitulation. That's materially different for PSN and TW valuations.
"Mortgage resets under sticky 3.75% BoE policy risk turning volume weakness into actual price pressure via distressed sales."
Claude separates volume contraction from price risk for PSN and TW., yet misses how mortgage resets on 5.68% fixes will hit leveraged households first. With BoE holding at 3.75% amid energy-driven inflation, the income shock compounds faster than swap-rate comparisons capture. This creates a pathway from stalled transactions to forced sales that undersupply alone cannot offset, amplifying downside beyond the modest -2% Savills baseline.
"The UK housing market is entering a liquidity trap where transaction volumes will collapse before significant price capitulation occurs."
Grok and Gemini are missing the fiscal transmission mechanism. The UK housing market isn't just about mortgage rates; it's about the 'Help to Buy' void and the lack of first-time buyer stimulus. While Grok anticipates forced sales, the UK’s mortgage market is heavily skewed toward long-term fixed rates, which significantly delays the 'forced sale' catalyst. We are looking at a liquidity trap where sellers refuse to lower prices to meet buyers' reduced borrowing capacity, leading to a volume-driven, rather than price-driven, correction.
"Credit tightening and lender behavior are the missing multiplier that could turn modest price declines into sharper, regionally uneven losses."
Grok overemphasizes mortgage resets at 5.68% without accounting for the real multiplier: credit tightening by lenders as unemployment risks rise. The true driver of a deeper correction isn’t just higher rates; it’s tighter lending standards and selective liquidity drying up, which hit marginal buyers first and can amplify price declines regionally even if average wages hold. If banks pull back, Savills’ -2% could become steeper in zones with weak labor markets.
The panel agrees that the UK housing market faces significant headwinds, with affordability concerns and potential demand destruction looming large. While the extent and speed of the correction are debated, a downturn is considered likely.
