FX.co ★ UK Input Producer Prices Accelerate to 8.3% YoY in September, Up from 6.1%

Input producer price inflation in the United Kingdom picked up sharply in September 2026, with the year-over-year rate rising to 8.3%, up from 6.1% in August 2026. The figures, updated on 21 October 2026, underscore mounting cost pressures facing UK manufacturers and other producers that buy goods and raw materials for further processing.

Both the current and previous readings are measured on a year-over-year basis, comparing each month’s input prices with the same month a year earlier. The jump from 6.1% in August to 8.3% in September suggests that cost pressures in the production pipeline are intensifying rather than easing, potentially feeding through to output prices and, ultimately, consumer inflation in the months ahead.

Market participants and policymakers are likely to scrutinise the September input PPI data as they assess the trajectory of underlying inflationary trends in the UK and the potential implications for monetary policy and corporate margins going into the final quarter of 2026.
