Overview
- For the week of Aug. 1–7 the Secretaría de Hacienda published DOF quotas that raise the diesel subsidy to about 75.9–76%, leaving a final diesel IEPS near 1.77 pesos per liter while slightly reducing supports for Magna and Premium gasoline.
- Hacienda says the fiscal cost of the fuel supports reached 42,000 million pesos in the first half of 2026, with a reported net revenue renunciation of 13,000 million pesos as of June 30.
- Officials state the net fiscal effect has been largely neutral so far because higher Pemex export transfers and a roughly 13% year‑over‑year rise in domestic gasoline and diesel volumes have offset part of the subsidy bill.
- The government is updating IEPS quotas weekly in the Diario Oficial de la Federación to smooth pump prices and has signaled that further changes could be required if international oil prices move higher.
- Broader revenue shifts are visible at midyear: total IEPS receipts hit 353.2 billion pesos, soft‑drink IEPS jumped about 59% thanks to tax changes and World Cup consumption, and weaker income tax receipts are creating tradeoffs for fiscal space.
