The Harmonised Inflation Rate YoY for Ireland (IE) climbed to 3.20% in December 2025, according to the latest release from the Sigmanomics database. This figure notably exceeds the market consensus estimate of 2.90% and the previous month’s 2.80%, signaling a marked acceleration in inflationary pressures. The current reading is the highest since September 2024, when inflation peaked at 3.40% before easing. This uptick reflects a complex interplay of domestic and external factors influencing price dynamics.

Drivers this month

• Energy prices contributed approximately 0.45 percentage points (pp) to the inflation increase, reflecting global oil price volatility.
• Housing and shelter costs added 0.38 pp, driven by rising rents and construction input prices.
• Food inflation rose modestly by 0.15 pp, influenced by supply chain disruptions.
• Transport costs edged up by 0.12 pp amid higher fuel and vehicle prices.

Policy pulse

The 3.20% inflation rate remains above the European Central Bank’s (ECB) 2% target, intensifying calls for a cautious but firm monetary policy stance. The Central Bank of Ireland, aligned with ECB policy, faces a delicate balance between curbing inflation and supporting growth.

Market lens

Immediate reaction: EUR/USD slipped 0.15% in the first hour post-release, while 2-year Irish government bond yields rose by 8 basis points, reflecting heightened inflation risk premiums. Breakeven inflation rates for Ireland edged up by 12 basis points, signaling market expectations of sustained inflationary pressures.

Examining core macroeconomic indicators alongside the inflation print provides a fuller picture of Ireland’s economic health. GDP growth for Q3 2025 was revised upward to 3.10% YoY, indicating robust economic momentum. Unemployment remains low at 4.20%, supporting consumer demand. Wage growth accelerated to 4.50% YoY, feeding into cost-push inflation.

Monetary Policy & Financial Conditions

The ECB has maintained a cautious tightening cycle, with the main refinancing rate at 3.25%. Financial conditions have tightened moderately, with credit spreads widening slightly. The Central Bank of Ireland’s liquidity measures remain supportive but are being gradually withdrawn to temper inflation.

Fiscal Policy & Government Budget

Fiscal policy remains expansionary, with the government targeting a 1.80% deficit of GDP in 2025. However, rising interest costs on public debt—now at 58% of GDP—pose medium-term risks. Recent stimulus measures focus on housing and green energy investments, which may sustain inflationary pressures in the near term.

Drivers this month

• Energy inflation surged by 0.45 pp, the largest monthly contribution since early 2024.
• Housing inflation rose by 0.38 pp, reflecting supply constraints and increased demand.
• Food and transport combined added 0.27 pp, driven by global commodity price shifts.

Policy pulse

The inflation rate’s breach of 3% intensifies ECB scrutiny. The current level is well above the 2% target and the 2.50% threshold that typically triggers more aggressive rate hikes. Market pricing now implies a 65% probability of a 25 basis point ECB hike in Q1 2026.

Market lens

Immediate reaction: EUR/USD declined 0.15%, reflecting concerns over ECB tightening. Irish 2-year yields rose 8 basis points, while inflation-linked bonds saw increased demand, pushing breakeven rates higher by 12 basis points.

Looking ahead, Ireland’s inflation trajectory will depend on multiple factors, including energy markets, wage dynamics, and policy responses. We outline three scenarios:

Bullish Scenario (20% probability)

• Energy prices stabilize or decline due to easing geopolitical tensions.
• Supply chain improvements reduce cost pressures on food and transport.
• ECB pauses rate hikes, supporting growth and moderating inflation to 2.50% by mid-2026.

Base Scenario (55% probability)

• Energy prices remain volatile but contained, sustaining inflation near 3%.
• Wage growth remains steady, keeping cost-push inflation elevated.
• ECB continues gradual tightening, with inflation easing to 2.80% by year-end 2026.

Bearish Scenario (25% probability)

• Energy prices spike due to renewed geopolitical shocks.
• Housing supply constraints worsen, pushing inflation above 4%.
• ECB accelerates rate hikes, risking recessionary pressures and financial market volatility.

Risks to the upside include persistent supply bottlenecks and wage-price spirals. Downside risks stem from potential demand shocks or faster-than-expected monetary tightening. The Sigmanomics database methodology integrates harmonised CPI data, market expectations, and macroeconomic indicators to provide a comprehensive inflation outlook.

In conclusion, Ireland’s Harmonised Inflation Rate YoY at 3.20% signals a significant inflation resurgence. This challenges policymakers to balance inflation control with growth support amid complex global and domestic dynamics. Financial markets have reacted swiftly, pricing in tighter monetary policy ahead. Fiscal policy remains supportive but must navigate rising debt costs. Structural inflation drivers, particularly in housing and energy, suggest that inflation may remain elevated for some time. Close monitoring of external shocks and geopolitical risks is essential for anticipating future inflation trends.

Investors and policymakers should prepare for a range of outcomes, with a bias toward sustained inflation above target in the near term. Strategic focus on supply-side reforms and energy diversification could mitigate inflationary pressures over the medium term.
