FX.co ★ Poland’s Producer Price Inflation Accelerates to 6.1% YoY in September 2026

Poland’s Producer Price Index (PPI) growth accelerated in September 2026, rising 6.1% year-over-year, up from 4.2% recorded in August 2026. The latest data, updated on 20 October 2026, signal a strengthening price dynamic at the producer level, potentially adding to upstream inflationary pressures in the Polish economy.

The figures are based on year-over-year comparisons, with the current reading reflecting the change in producer prices in September 2026 versus September a year earlier. Similarly, the previous 4.2% figure measured the change in August 2026 relative to August of the prior year. The sharp month-to-month acceleration in the annual rate suggests that cost pressures facing producers have intensified, which may eventually filter through to consumer prices and influence monetary policy and business planning.
