UK House Prices Slip 0.6% in May as Iran Conflict Fuels Rate Hikes

AI Summary
UK house prices fell 0.6% in May, the first monthly decline this year, as higher borrowing costs linked to the Iran conflict dampen demand. While prices remain 1.7% above last year, the annual growth pace has slowed sharply, prompting analysts to forecast further falls.

UK house prices fell 0.6% in May, marking the first monthly decline this year as rising interest rates—spurred by the war in Iran—weakened buyer demand. The average home price stood at £278,024, still 1.7% higher than a year ago but far below the 3% annual growth recorded in April.

May’s Price Drop Signals a Market Cool‑Down

Nationwide’s chief economist Robert Gardner described the slowdown as “expected” given the uncertainty from Middle‑East conflict, higher energy costs, and climbing market interest rates.

Key Numbers Highlight the Shift

  • Month‑on‑month price change: -0.6%
  • Year‑on‑year price level: +1.7% (still above last year)
  • Two‑year fixed mortgage rate (end‑May): 5.68%
  • Five‑year fixed mortgage rate (end‑May): 5.63%
  • Bank of England base rate (April vote): 3.75%

Why the Housing Market Is Feeling the Pinch

Higher borrowing costs are eroding household spending power. Tom Bill of Knight Frank noted the slowdown arrives “precisely when momentum would normally be building”. Savills revised its outlook, now expecting a 2% fall in average house prices this year, reversing a prior forecast of a 2% rise.

Despite the rise in rates, Gardner said the impact on affordability has been “modest” because swap rates, which underpin fixed‑rate pricing, remain below 2023 peaks.

Outlook: A Potential Short‑Lived Softening?

Analysts such as Martin Beck of WPI Strategy warn that even if rates ease, the market stays vulnerable: mortgage repayments still consume a large share of incomes, and a weakening labour market could pose a greater threat than interest rates alone.

Bank of England Governor Andrew Bailey signalled no rush to raise rates further, keeping the policy rate at 3.75% while monitoring the war’s trajectory and weak economic growth. The consensus is that any near‑term dip may be temporary if energy prices stabilise, but the sector remains exposed to ongoing geopolitical and financial pressures.
