UK growth edges higher as inflation keeps interest rates in focus

New UK growth figures and stronger US inflation put household borrowing costs back in the spotlight. Here is what the latest official releases show—and what they do not tell us about the next move in rates.

UK economy: modest monthly growth, stronger three-month picture

The UK economy grew by an estimated 0.1% in August, following 0.4% growth in July, according to figures released today. Across the three months to August, output increased by 0.7% compared with the previous three months. Production supported August's increase, while services were flat and construction declined. Early GDP estimates can be revised. Source: ONS, 15 October 2026.

Bank Rate remains at 3.75%

The Bank of England's latest decision left Bank Rate at 3.75%. Its next scheduled decision is on 5 November. In its September update, the Bank warned that prolonged energy-price pressures could make inflation more persistent. That is a risk assessment, rather than a commitment to a particular decision in November. Source: Bank of England, latest decision and current rate.

US inflation: September figures are now published

US consumer prices rose 3.7% over the year to September, with a seasonally adjusted monthly increase of 0.6%, the Bureau of Labor Statistics reported on 14 October. Energy prices increased by 5.2% over the month; gasoline accounted for more than half of the overall monthly rise. These are published results, replacing the forecasts in Monday's briefing.

Mortgages: averages need context

Rightmove's tables updated on 15 October show average two-year and five-year fixed rates of 5.53% and 5.51%, respectively. These are Podium-based figures covering around 95% of the mortgage market, based on products with fees of approximately £999. They are a snapshot of that dataset, not a quotation or a rate available to every borrower. Deposit, equity, fees, circumstances and lender criteria affect individual offers.

What this means for households

Analysis: Today's releases give a mixed picture: the UK economy is growing, while inflation remains a concern for policymakers. Neither release establishes the direction of the next UK interest-rate decision. For household planning, market averages provide context; the relevant costs are those attached to an individual's actual mortgage, savings account or other financial product.

Live oil, gold, gilt and swap prices, and market-implied probabilities of rate changes, are omitted from this edition because a consistent, time-stamped set of those figures has not been verified.
