FX.co ★ North Rhine-Westphalia Inflation Turns Negative in October as CPI Slips 0.2% MoM

Consumer prices in Germany’s largest federal state, North Rhine-Westphalia, declined in October 2026, signaling a notable cooling in regional inflation dynamics. The state’s Consumer Price Index (CPI) fell by 0.2% month-on-month, compared with a 0.6% increase recorded in September 2026, according to data updated on 30 October 2026.

The move from positive to negative monthly inflation suggests a sharp reversal in short-term price momentum. On a month-over-month basis, the latest “actual” figure reflects price changes in October relative to September, while the “previous” 0.6% reading captured the change in September versus August. This swing into negative territory in October may indicate easing price pressures at the start of the final quarter of 2026, and will be closely watched as an early signal for broader German inflation trends.
