Argentina’s Consumer Price Index (CPI) for December 2025 increased by 2.80%, according to the latest release from the Sigmanomics database on January 13, 2026. This figure exceeded market expectations of 2.50% and edged above November’s 2.50% reading. The month-over-month rise signals a slight acceleration in inflation after a period of relative moderation in October and November. However, the inflation rate remains far below the extreme spikes seen in mid-2025, such as August’s 37.60% and September’s 33.60%, reflecting ongoing volatility in price dynamics.
Drivers this month
- Shelter and utilities costs contributed approximately 0.90 percentage points to the monthly increase.
- Food and beverage prices rose by 0.70 percentage points, reflecting supply chain pressures and currency depreciation.
- Transport and fuel costs added 0.50 percentage points, influenced by global oil price fluctuations.
Policy pulse
The 2.80% monthly inflation rate remains well above the Central Bank of Argentina’s implicit target range of 1.50%–2.00%, indicating persistent inflationary pressures. This complicates the monetary authority’s efforts to anchor inflation expectations amid a fragile economic recovery.
Market lens
Immediate reaction: The Argentine peso (ARS) depreciated by 0.40% against the US dollar within the first hour post-release, while short-term government bond yields rose by 15 basis points, reflecting heightened inflation risk premiums.
Examining core macroeconomic indicators alongside the CPI reveals a complex inflationary environment. The 12-month average inflation rate remains elevated at approximately 14.10%, driven by volatile food and energy prices. Compared to December 2024, when inflation was 31.80%, the current pace suggests some moderation but still signals entrenched inflation.
Monetary Policy & Financial Conditions
The Central Bank of Argentina has maintained a tight monetary stance, with benchmark interest rates hovering near 70% nominal annual rates to combat inflation. However, real rates remain negative due to high inflation, limiting the effectiveness of monetary tightening. Financial conditions are tight, with credit growth subdued and risk premiums elevated.
Fiscal Policy & Government Budget
Fiscal policy remains constrained by high debt servicing costs and limited revenue growth. The government’s budget deficit is projected at 4.50% of GDP for 2025, with limited room for expansionary measures. Subsidy reforms and targeted social spending aim to balance fiscal discipline with social stability.
External Shocks & Geopolitical Risks
Argentina faces external headwinds including commodity price volatility and geopolitical tensions affecting trade routes. The recent global energy price surge has pressured domestic fuel prices, feeding into inflation. Additionally, currency volatility driven by capital outflows adds to inflationary risks.
This chart highlights a persistent inflationary trend with intermittent spikes, reflecting structural vulnerabilities in Argentina’s economy. The recent uptick signals that inflationary pressures are not abating, necessitating vigilant policy responses to avoid a resurgence of hyperinflationary episodes.
Market lens
Immediate reaction: The ARS/USD exchange rate weakened by 0.40%, while two-year government bond yields rose by 15 basis points, indicating increased inflation risk perception among investors. Inflation-linked bonds saw a modest rally, reflecting expectations of continued high inflation.
Looking ahead, Argentina’s inflation trajectory hinges on several key factors. The baseline scenario projects monthly inflation stabilizing around 2.50%–3.00% in early 2026, supported by tight monetary policy and moderate fiscal discipline. However, upside risks include renewed currency depreciation, external commodity shocks, and wage-price spirals.
Scenario Analysis
- Bullish (20% probability): Inflation moderates to below 2% monthly by mid-2026, driven by successful fiscal reforms and stable currency conditions.
- Base (60% probability): Inflation remains elevated around 2.50%–3.00% monthly, with persistent but manageable inflationary pressures.
- Bearish (20% probability): Inflation accelerates above 3.50% monthly due to external shocks and policy slippages, risking a return to hyperinflationary dynamics.
Structural & Long-Run Trends
Argentina’s inflation challenges are deeply rooted in structural factors such as fiscal imbalances, currency volatility, and indexation mechanisms. Long-run inflation expectations remain elevated, complicating efforts to achieve price stability. Sustainable progress requires comprehensive reforms addressing fiscal discipline, monetary credibility, and external vulnerabilities.
December 2025’s CPI reading of 2.80% underscores the persistent inflation challenge facing Argentina. While the rate is far below the extreme spikes seen earlier in 2025, it remains above the Central Bank’s comfort zone. Policymakers must balance tight monetary conditions with fiscal realities and external risks to avoid inflation entrenchment. Financial markets remain cautious, pricing in continued volatility. Structural reforms will be critical to anchoring inflation expectations and fostering macroeconomic stability in 2026 and beyond.
