The partial implementation represents a 0.5-percent adjustment rate, substantially below the accumulated inflation-based increases mandated by law. Remaining tax increments corresponding to 2024 and 2025 indexation are deferred until June 1, 2026, continuing the government’s strategy of staggered implementation to limit inflationary impact. Consultancy Economía y Energía estimates that fuel tax postponements during 2025 resulted in foregone fiscal revenues totaling $2.326 billion.
March 2026 fuel sales reached 1,394,360 cubic meters across gasoline and diesel categories, declining 1.8 percent compared to March 2025. Budget gasoline fell 4.1 percent while standard diesel dropped 5.8 percent. Premium segments showed opposite trends, with high-octane gasoline rising 2.7 percent and premium diesel advancing 6.4 percent year-over-year, though insufficient to offset overall volume contraction.
The tax adjustment coincides with international crude oil price escalation. Brent crude reached intraday highs of $126.41 per barrel in late April 2026, the highest level since March 2022, driven by the ongoing blockade of the Strait of Hormuz following conflict between the United States and Israel against Iran. West Texas Intermediate rose to $108.41 per barrel. President Trump indicated the naval blockade of Iranian ports could extend several months pending nuclear negotiations, sustaining upward pressure on global energy markets that Argentina must navigate through controlled domestic pricing adjustments.
