Table of Contents
Poland's Core Inflation Rate YoY for December 2025 remained steady at 2.7%, matching November's reading but below market expectations of 2.8%. This marks a continuation of a downward trend from a peak of 3.6% in April 2025. The figure signals persistent but moderating inflationary pressures in the Polish economy amid evolving domestic and external conditions.
Drivers this month
- Stable energy prices helped contain core inflation pressures.
- Moderate wage growth limited upward cost-push effects.
- Supply chain normalization reduced input cost volatility.
Policy pulse
The 2.7% core inflation rate remains slightly above the National Bank of Poland’s (NBP) target midpoint of 2.5%, suggesting a cautious stance on monetary policy. The central bank is likely to maintain current interest rates while monitoring inflation dynamics closely.
Market lens
Immediate reaction: PLN strengthened modestly against the EUR post-release, reflecting market relief at the stable inflation figure. Polish 2-year government bond yields edged down by 5 basis points, signaling reduced near-term rate hike expectations.
Core inflation strips out volatile food and energy prices, providing a clearer view of underlying price trends. Poland’s December 2025 core inflation rate of 2.7% YoY compares with 3.0% in November and 3.2% in October, confirming a steady deceleration over the past quarter. The 12-month average core inflation rate stands at approximately 3.1%, underscoring the recent moderation.
Monetary Policy & Financial Conditions
The National Bank of Poland has held its benchmark interest rate steady at 6.75% since November 2025, reflecting a wait-and-see approach amid easing inflation. Financial conditions remain moderately tight, with credit growth slowing slightly due to cautious bank lending and elevated borrowing costs.
Fiscal Policy & Government Budget
Poland’s fiscal stance remains expansionary but prudent. The government’s 2025 budget deficit narrowed to 2.8% of GDP, aided by robust tax revenues and controlled public spending. Fiscal support is targeted towards infrastructure and social programs, with limited inflationary impact.
External Shocks & Geopolitical Risks
Global commodity prices stabilized in late 2025, reducing imported inflation risks. However, geopolitical tensions in Eastern Europe and supply chain uncertainties persist as downside risks. The EU’s evolving regulatory environment also poses medium-term challenges for Poland’s export sectors.
This chart reveals a consistent easing of core inflation pressures in Poland since mid-2025. The trend suggests that underlying inflation is moving closer to the NBP’s target range, supporting a stable monetary policy outlook in the near term.
Market lens
Immediate reaction: PLN/EUR appreciated 0.3% within the first hour after the release, while 2-year Polish government bond yields declined by 5 basis points. This reflects market confidence that inflation is stabilizing, reducing the likelihood of aggressive rate hikes.
Looking ahead, Poland’s core inflation trajectory will hinge on several factors. The baseline scenario (60% probability) envisions inflation stabilizing around 2.5–2.8% through mid-2026, supported by moderate wage growth and contained energy prices.
Bullish scenario (20% probability)
Stronger-than-expected productivity gains and supply chain improvements could push core inflation below 2.5% by Q3 2026, allowing the NBP to consider rate cuts to stimulate growth.
Bearish scenario (20% probability)
Renewed geopolitical tensions or a surge in global commodity prices could reignite inflationary pressures, pushing core inflation above 3.0%, prompting the NBP to tighten monetary policy further.
Structural & Long-Run Trends
Poland’s long-term inflation dynamics are influenced by demographic shifts, labor market tightness, and EU integration. Aging population and labor shortages may sustain wage pressures, while EU structural funds support productivity enhancements. These factors will shape inflation’s baseline path over the next decade.
In conclusion, Poland’s December 2025 core inflation rate of 2.7% YoY signals a stable but cautious inflation environment. The steady decline from earlier 2025 highs reflects improving supply conditions and effective monetary-fiscal coordination. While risks remain, the current data supports a neutral monetary policy stance in the near term.
Investors and policymakers should monitor wage developments, external shocks, and geopolitical risks closely. The balance of risks suggests a moderate inflation outlook, with potential for either gradual easing or renewed pressures depending on global and domestic developments.
