Real Fuel Costs in Argentina Decline to Nine-Year Low Amid Price Liberalization and Regional Disparities

Current data from the Instituto de Economía of Universidad Argentina de la Empresa (Ineco-UADE) reveal that filling a 55-liter tank with regular gasoline nationwide costs approximately 99,407 pesos in December 2025, representing around 5% of the average gross registered private sector salary. This expenditure marks a decrease compared to previous administrations when evaluated in real terms. The adjusted cost was 102,026 pesos during Mauricio Macri’s government and peaked at 122,521 pesos under Alberto Fernández, reaching an all-time real high of 204,168 pesos in January 2024. Under President Javier Milei’s administration, the real average cost of a full tank has been 112,974 pesos, about 7.8% lower than the preceding term, highlighting a normalization following initial price adjustments linked to the dismantling of discretionary price controls.

Fuel price variation across provinces remains significant, with a 36% gap between the lowest and highest prices. Patagonia provinces such as Tierra del Fuego, Santa Cruz, and Neuquén consistently post lower prices, influenced by reduced logistical costs and lighter tax burdens. Conversely, northern and central provinces including Salta, Formosa, and La Rioja record the highest prices due to greater transportation expenses and elevated local taxes. Even within Buenos Aires Province, diesel and gasoline prices vary widely between localities, driven by similar factors.

In terms of fuel type efficiency and costs, gas natural compressed (GNC) offers the lowest cost per kilometer at 58 pesos, representing a 59% savings compared to regular gasoline. Gasoline premium fuels are priced higher on a per-liter basis but offer marginally better fuel economy, although not all vehicles benefit technically from this difference.

Fuel price increases during 2025 have been moderate despite tax hikes, aided by government decisions to defer specific fuel taxes multiple times to contain inflationary pressures. The Confederation of Petroleum Commerce Entities (CECHA) reported a small fuel price rise of 1.75% effective January 2026, below inflation rates, reflecting continued efforts to balance cost recovery and economic stability. The sector faces uncertainties from international crude price fluctuations and pending tax policy adjustments linked to the national budget.

Technological infrastructure within service stations is prepared to handle prices exceeding 2,000 pesos per liter for premium fuels and diesel, anticipated due to fiscal adjustments. This technological readiness facilitates price transparency and rapid updates without significant operational upgrades needed at fueling points.

Overall, Argentina’s fuel market demonstrates a shift towards realistic pricing aligned with international benchmarks, improved affordability in real terms, and marked regional price variability shaped by structural taxation and logistics, all under a framework of cautious fiscal policy management.
