Sweden’s CPIF (CPI at constant interest rates) rebounded sharply in September 2026, reversing the brief dip seen the month before, according to the latest data updated on 7 October 2026. On a month‑over‑month basis, the indicator rose by 0.9% in September, following a 0.2% decline in August 2026.
The move from -0.2% to 0.9% signals a clear turnaround in monthly price dynamics, as measured under the CPIF framework that holds interest rates constant. In August, the negative reading indicated a marginal month‑to‑month fall in prices compared with July, while September’s figure shows a renewed uptick versus August.
The comparison underscores a shift from temporary disinflationary pressure to renewed price growth within just one month. Market participants tracking Sweden’s inflation path will likely interpret the September print as evidence that the softness seen in August was short‑lived, with price levels resuming their upward trajectory as autumn began.
