Overview
- Argentina’s Energy Secretariat published resolutions 605/2025 and 604/2025, lifting wholesale gas (PIST) with an average 0.53% impact on January gas bills and raising the electricity generation reference about 3.88%.
- ENARGAS and ENRE were instructed to reflect the new values on consumer invoices, with detailed tariff tables due shortly to define final household impacts.
- The government is shifting in 2026 to a simplified subsidy scheme with only two user categories, automatic RASE migration, and seasonal or consumption-block bonifications that concentrate aid on lower-income households.
- Mexico’s updated IEPS rates take effect January 1 for fuels, sugary and diet beverages, sueros with sweeteners, and tobacco, pushing up prices for drinks and cigarettes, while premium gasoline is outside the current pact.
- President Claudia Sheinbaum reaffirmed that regular gasoline will not rise in January under a voluntary cap below 24 pesos per liter, with specialists suggesting Pemex or terminals may absorb the tax increase as Banxico flags near-term inflation pressure.
