Overview
- Hacienda published in the Official Gazette the 2026 IEPS quotas effective January 1: 6.7001 pesos per liter for Magna, 5.6579 for Premium, and 7.3634 for diesel.
- Officials underscored that the increase is an automatic, inflation‑linked update required by law rather than a discretionary policy change.
- The consumer impact is not automatic because Hacienda can grant weekly IEPS stimuli and prices also reflect exchange rates and international oil benchmarks.
- In 2025 the government stopped fuel stimuli from early April, yet retail prices stayed contained by a voluntary cap of 23.99 pesos for Magna and lower WTI; latest averages were 23.38 (Magna), 25.88 (Premium) and 26.42 (diesel) pesos per liter.
- The decree also updates IEPS components for other fossil fuels and the share for states, setting 59.13, 72.16 and 49.08 centavos per liter for Magna, Premium and diesel respectively.
