Mexico's Finance and Public Credit Ministry (SHCP) set the diesel fuel tax stimulus at 65 percent for the week of August 8 to 14, published Friday in the Diario Oficial de la Federación. The benefit amounts to a discount of 4.78 pesos per liter for freight carriers, down from 75.9 percent and 5.58 pesos the prior week.

The adjustment is part of the mechanism through which the Finance Ministry recalibrates the Special Tax on Production and Services (IEPS) on fuels each week based on the movement of international crude oil prices. For the same week, the Magna gasoline discount fell from 2.45 to 1.40 pesos per liter and the Premium discount to 0.33 pesos, with an IEPS rate of 5.33 pesos, according to Expansión. Diesel powers Mexico's freight fleet and agricultural sector, so any change in its stimulus translates immediately into pump prices and transportation costs across the country.

In international markets, the West Texas Intermediate benchmark crude moved from 81.30 to 78.18 dollars per barrel over the week, with a high of 82.24 dollars, while Brent moved from 84.45 to 83.55 dollars, according to Energía a Debate. At the pump, Magna gasoline closed the week at an average of 23.69 pesos per liter, Premium at 28.52 pesos, and diesel at 27.03 pesos, in line with the voluntary agreement that keeps regular gasoline below 24 pesos. The diesel IEPS rate stood at 2.58 pesos per liter, the largest discount among the three fuels, and the ministry publishes the agreement each Friday in the Diario Oficial de la Federación to govern the following week.

The new stimulus applies from Saturday, August 8 and remains in effect through August 14. The next agreement will be published on Friday, August 14, when the Finance Ministry recalibrates the discount based on crude oil movements.
