EU Core Inflation Rate YoY: December 2025 Analysis and Outlook
The European Union’s core inflation rate year-over-year (YoY) held steady at 2.40% in December 2025, matching the previous month’s reading but falling slightly short of the 2.50% consensus estimate. This persistence in core inflation amid evolving macroeconomic conditions signals a complex interplay of factors shaping the EU’s inflation trajectory. Drawing on the latest data from the Sigmanomics database, this report contextualizes the current reading against recent history, explores underlying drivers, and assesses implications for monetary policy, fiscal stance, and financial markets.
Table of Contents
The EU’s core inflation rate has remained remarkably stable at 2.40% over the past five months, reflecting persistent underlying price pressures despite external shocks and policy interventions. This stability contrasts with the broader headline inflation, which has shown more volatility due to energy and food price swings. The 2.40% core rate remains above the European Central Bank’s (ECB) 2% target, underscoring ongoing inflationary challenges in the region.
Drivers this month
- Shelter and housing costs contributed approximately 0.18 percentage points to core inflation.
- Services inflation remained elevated, adding 0.12 percentage points.
- Used car prices exerted a mild downward pressure, subtracting 0.05 percentage points.
Policy pulse
The current 2.40% core inflation rate sits just above the ECB’s inflation target, signaling a need for cautious monetary tightening. The ECB’s recent rate hikes have aimed to temper demand-driven inflation, but the persistent core rate suggests underlying price stickiness.
Market lens
Immediate reaction: EUR/USD slipped 0.15% within the first hour post-release, reflecting market disappointment at the unchanged core inflation and the slight miss versus expectations. Short-term yields on German bunds edged higher by 3 basis points, signaling modest repricing of ECB policy expectations.
Core inflation excludes volatile food and energy prices, providing a clearer view of underlying price trends. The 2.40% reading in December 2025 matches the level recorded in July 2025, indicating a plateau after a gradual rise from 2.30% in August through October. The 12-month average core inflation stands at 2.35%, slightly below the current reading but consistent with a persistent inflationary environment.
Monetary policy & financial conditions
The ECB has raised its main refinancing rate by 125 basis points since mid-2024, aiming to anchor inflation expectations. Financial conditions have tightened, with the Euro Stoxx 50 index showing increased volatility and the EUR/USD exchange rate fluctuating around 1.08. Credit growth has slowed, yet wage growth remains firm at 3.20% YoY, sustaining demand-side inflation pressures.
Fiscal policy & government budget
Fiscal policy remains moderately expansionary, with EU governments maintaining stimulus measures to support post-pandemic recovery. The aggregate budget deficit is projected at 3.10% of GDP for 2025, slightly above the pre-pandemic average, which may sustain demand and inflationary pressures in the near term.
External shocks & geopolitical risks
Energy price volatility has moderated following the EU’s diversification of supply sources. However, geopolitical tensions in Eastern Europe and supply chain disruptions continue to pose upside risks to inflation. The resilience of core inflation despite these shocks highlights entrenched price pressures in services and housing sectors.
Chart insight
The chart illustrates a plateauing trend in core inflation, reversing the modest decline observed in late 2024. This signals that inflationary forces in the EU economy remain robust, particularly in non-energy sectors.
What This Chart Tells Us: Core inflation is trending upward compared to pre-2025 levels and shows resistance to recent monetary tightening. This suggests that inflation expectations and wage-price dynamics remain elevated, requiring continued vigilance from policymakers.
Market lens
Immediate reaction: Following the release, the EUR/USD currency pair declined by 0.15%, reflecting market concerns over persistent inflation. German 2-year bund yields rose by 3 basis points, indicating a slight increase in expectations for further ECB rate hikes. The Euro Stoxx 50 index dropped 0.40%, signaling investor caution.
Looking ahead, the core inflation rate’s trajectory will depend on several factors, including monetary policy effectiveness, fiscal stimulus, and external shocks. We outline three scenarios based on current data and trends:
Bullish scenario (20% probability)
- Core inflation falls below 2.00% by mid-2026 due to successful ECB tightening and easing supply constraints.
- Wage growth moderates, and fiscal policy tightens, reducing demand-side pressures.
- Geopolitical risks subside, stabilizing input costs.
Base scenario (60% probability)
- Core inflation remains around 2.30–2.50% through 2026, reflecting sticky price dynamics.
- Monetary policy continues gradual tightening with limited impact on entrenched inflation.
- Fiscal policy remains moderately supportive, balancing growth and inflation risks.
Bearish scenario (20% probability)
- Core inflation rises above 2.60% due to renewed supply shocks or wage-price spirals.
- ECB faces pressure to accelerate rate hikes, risking growth slowdown.
- Fiscal stimulus increases amid political pressures, fueling demand-pull inflation.
Policy pulse
The ECB’s forward guidance will be critical in shaping inflation expectations. Persistent core inflation above target may prompt further rate hikes, while signs of easing could allow a pause. Market participants will closely monitor wage data and service sector prices for clues.
The EU’s core inflation rate at 2.40% in December 2025 highlights the ongoing challenge of taming inflation amid complex economic forces. While headline inflation may fluctuate with energy prices, core inflation’s persistence signals structural price pressures. Policymakers face a delicate balancing act between containing inflation and supporting growth. Financial markets have reacted cautiously, pricing in moderate further tightening. External risks and fiscal policy choices will remain key variables in the inflation outlook.
Key Markets Likely to React to Core Inflation Rate YoY

Indicator vs. EURUSD Since 2020
Since 2020, the EU core inflation rate and EURUSD have shown a moderate inverse correlation. Rising core inflation often coincides with EURUSD appreciation due to expectations of ECB tightening. For example, the 2021 inflation surge saw EURUSD climb from 1.17 to 1.22. However, geopolitical shocks and divergent fiscal policies have occasionally disrupted this pattern.

Insight: EU Core Inflation vs. EURUSD Since 2020
Tracking EU core inflation against EURUSD since 2020 reveals a moderate inverse correlation. Periods of rising core inflation often coincide with EURUSD appreciation, driven by expectations of ECB tightening. For instance, the inflation surge in 2021 saw EURUSD rise from 1.17 to 1.22. However, geopolitical events and divergent fiscal policies have occasionally disrupted this trend, underscoring the complex interplay between inflation and currency markets.
The December 2025 core inflation rate of 2.40% remains unchanged from November and is slightly above the 12-month average of 2.35%. This stability follows a period of mild fluctuations between 2.30% and 2.40% since mid-2025. The persistence of core inflation at this elevated level suggests that underlying price pressures are not abating despite monetary tightening.
Comparing to historical data, the current core inflation rate is higher than the 1.80% average seen in 2023 and 2024, reflecting a structural shift in inflation dynamics post-pandemic and amid ongoing supply constraints.
