Key takeaways

• Markets are now pricing in two, possibly three, quarter-point rate rises over the coming year, a sharp reversal from the downward path expected in early 2026.
• The Bank of England held Bank Rate at 3.75% on 30 July 2026, with three of nine MPC members voting for an increase.
• Average five-year fixed mortgage rates have risen from below 4% in January to around 4.8%, cutting buyer purchasing power by roughly 9%, according to Zoopla.
• Price growth is cooling as a result, with UK house prices up 2.0% in the year to June 2026, down from 3.0% the previous month.

For much of the past two years, the story of UK borrowing costs has been one of gradual descent. That narrative has now reversed. As of late August 2026, financial markets are pricing in the prospect of further Bank Rate rises rather than the cuts that had been widely expected at the start of the year, driven largely by the inflationary effects of the conflict in the Middle East. The shift is feeding directly through to mortgage pricing and, in turn, to what buyers can afford, reshaping the market as the autumn selling season approaches. ## A reversed rate outlook

The turnaround in expectations has been striking. Analysis of government bond pricing shows how far sentiment has moved since geopolitical tensions escalated earlier in the year.

The Bank of England has so far held its position. On 30 July, its Monetary Policy Committee left Bank Rate unchanged, though the vote revealed a committee that is far from united on the direction of travel.

• The path for rates on 16 February 2026, before the conflict broke out, pointed downwards.
• By 21 August 2026, market pricing had shifted to imply two, and possibly three, quarter-point rises over the following year.

Market prices suggest the indicative rate will be 4.33% in 12 months' time.

The impact on mortgages and buying power

Higher rate expectations translate quickly into higher mortgage pricing, and the effect on affordability has been material. Buyers looking to move this autumn face meaningfully higher monthly costs than those who transacted at the start of the year.

Savills has noted that this outcome is consistent with its own forecasting, and that a durable improvement in mortgage pricing is unlikely until the geopolitical picture stabilises.

A cooling in price growth

Reduced buying power and fewer transactions are now visible in the official price data. The annual rate of house price growth has slowed, with the effect felt most acutely across southern England.

The picture is not uniformly negative. Buyer searches have begun to recover as summer draws to a close, an early sign that demand is regrouping even as affordability remains stretched.

The central question for the months ahead is whether the current inflationary pressures prove temporary or embedded. Until there is greater clarity, borrowing costs are likely to remain a constraint on activity rather than a catalyst for it. Silkwood Group will continue to monitor the rate outlook and its implications for the UK market as the autumn period unfolds.
