The United Kingdom’s core Consumer Price Index (CPI) rose 0.2% month-over-month in September 2026, easing from a 0.3% increase recorded in August 2026. The latest figures, updated on 21 October 2026, indicate a modest slowdown in underlying inflation pressures compared with the previous month.
On a month-over-month basis, the “actual” September reading reflects the change in prices relative to August, while the “previous” August figure captures the change versus July. The deceleration from 0.3% to 0.2% suggests that core price growth—excluding the most volatile components—is losing some momentum, a development that could factor into market expectations for future monetary policy decisions.
Investors and analysts will be watching upcoming releases closely to see whether this softer trend in core inflation persists, potentially signaling a more sustained cooling in underlying price pressures across the UK economy.
