Argentina’s inflation rate for December 2025 registered a 2.8% increase from November 2025, according to the latest release from the Sigmanomics database. This figure outpaced market expectations of 2.2% and rose from November’s 2.5%, marking a notable acceleration in monthly inflation. The 12-month average inflation rate now stands at approximately 2.1% MoM, reflecting a persistent upward trend over the past year.

Drivers This Month

• Energy prices surged by 4.1%, driven by higher global oil costs and domestic fuel taxes.
• Food and beverages inflation accelerated to 3.2%, fueled by supply chain disruptions and seasonal demand.
• Core inflation components, excluding volatile items, rose 2.4%, indicating broad-based price pressures.

Policy Pulse

The inflation reading remains well above the Central Bank of Argentina’s target band of 2.0% monthly, complicating efforts to anchor inflation expectations. The central bank has maintained a hawkish stance, with recent interest rate hikes totaling 150 basis points since October 2025. However, the December print suggests that monetary tightening has yet to fully temper inflationary momentum.

Market Lens

Following the release, the Argentine peso (ARS) weakened 0.7% against the US dollar, reflecting investor concerns about persistent inflation and potential further monetary tightening. Short-term government bond yields rose by 15 basis points, signaling increased risk premia. Equity markets showed muted reaction, with the Merval index holding steady amid mixed corporate earnings reports.

Examining Argentina’s broader macroeconomic indicators provides context for the inflation surge. GDP growth for Q4 2025 is estimated at 1.1% quarter-over-quarter, a slowdown from 1.5% in Q3, reflecting weaker domestic demand. Unemployment remains elevated at 9.8%, limiting wage-driven inflation but also constraining consumer spending power.

Monetary Policy & Financial Conditions

The Central Bank’s policy rate currently stands at 70%, up from 68.5% in November, as part of its ongoing battle against inflation. Credit growth has slowed to 1.2% MoM, indicating tighter financial conditions. Inflation expectations for 2026 remain elevated at 55% annually, according to recent surveys.

Fiscal Policy & Government Budget

The government’s fiscal deficit widened slightly to 4.2% of GDP in December 2025, driven by increased social spending and subsidies aimed at cushioning vulnerable populations from inflation’s impact. Debt servicing costs have risen amid higher inflation and interest rates, pressuring the budget further.

External Shocks & Geopolitical Risks

Global commodity price volatility, particularly in energy and agricultural products, continues to influence Argentina’s inflation trajectory. Additionally, geopolitical tensions in key trade partners have disrupted supply chains, exacerbating cost-push inflation. The recent depreciation of the ARS has also increased import costs, feeding into domestic prices.

What This Chart Tells Us

Market Lens

Immediate reaction: The ARS/USD exchange rate weakened by 0.7% within the first hour post-release, reflecting market concerns over inflation persistence. Short-term bond yields rose, while equity markets remained cautious but stable.

Looking ahead, Argentina faces a complex inflation outlook shaped by domestic and external factors. We outline three scenarios:

Bullish Scenario (20% probability)

Inflation moderates to below 2.0% MoM by Q2 2026, driven by effective monetary tightening, fiscal consolidation, and stable commodity prices. This would restore some confidence in the ARS and reduce inflation expectations.

Base Scenario (60% probability)

Inflation remains elevated around 2.5–3.0% MoM through mid-2026, reflecting ongoing supply constraints, moderate peso depreciation, and gradual policy tightening. Inflation expectations remain sticky but manageable.

Bearish Scenario (20% probability)

Inflation accelerates above 3.5% MoM due to renewed currency weakness, fiscal slippage, and external shocks such as commodity price spikes or geopolitical disruptions. This would force aggressive monetary tightening and risk recession.

Policy Implications

The Central Bank faces a delicate balancing act. Further rate hikes may be necessary to anchor inflation expectations but risk stifling growth. Fiscal authorities must also prioritize deficit reduction to ease inflationary pressures and support currency stability.

Argentina’s December 2025 inflation rate of 2.8% MoM signals persistent price pressures despite ongoing policy efforts. The acceleration from November’s 2.5% and the highest monthly reading since May 2025 highlight the challenges ahead. Monetary tightening and fiscal discipline remain critical to curbing inflation and stabilizing the economy. External risks and structural factors will continue to shape the inflation path in 2026.
