UK House Prices Slip for Third Month as Iran War Fuels Mortgage Strain

AI Summary
UK house prices fell for the third consecutive month in May, dropping 0.1% to £298,806 amid higher mortgage rates linked to the Iran conflict. Despite a modest 0.5% annual rise, analysts warn that rising inflation expectations and a looming energy‑price‑cap hike could keep the market under pressure.

Lead: Prices Decline as Geopolitical Tensions Hit Affordability

UK house prices fell unexpectedly in May, marking the third straight monthly decline. The dip reflects higher mortgage costs driven by the war in Iran, which is stretching buyer budgets and dampening demand.

War‑Driven Mortgage Pressure Triggers Third Consecutive Monthly Drop

Amanda Bryden, head of mortgages at Halifax, said property trends continue to mirror uncertainty from Middle‑East developments. Even after recent mortgage‑rate cuts, inflation expectations keep borrowing costs above early‑year levels, limiting affordability.

Data Snapshot: Price, Rate and Inflation Figures

  • Average UK home price: £298,806 in May (‑0.1% vs. April).
  • Annual price growth: 0.5% (up from 0.4% in April, below the 1% forecast).
  • Two‑year fixed mortgage rate: 5.66% (up from 4.83% in early March).
  • Five‑year fixed mortgage rate: 5.62% (up from 4.95%).
  • UK inflation (April): 2.8%, the lowest in over a year.
  • Energy‑price‑cap increase expected in July: 13% to £1,850 per year.

Impact: A Buyers’ Market Tempered by First‑Time Buyer Caution

OnTheMarket president Jason Tebb described the current environment as “the strongest buyers’ market we have seen in many years,” with ample stock and steadier prices. However, Halifax notes that activity among first‑time buyers is “more subdued,” suggesting lingering affordability concerns.

Economists warn that the upcoming rise in the household energy price cap could push inflation higher, potentially prompting further mortgage‑rate adjustments.

Outlook: Prices Likely to Hold Steady but Vulnerable to Cost Pressures

Halifax expects house prices to remain “broadly stable” in the near term, provided mortgage rates do not climb sharply. Yet, the combination of higher energy costs, possible inflation upticks, and persistent geopolitical uncertainty means the market could face renewed downward pressure later in the year.
