# Mexico fuel price cap negotiations and compliance > Live situation record from CLSTR: https://clstr.news/situations/mexico-diesel-price-cap > Updated: 2026-08-19T21:09:54.000Z. Sources: 74. Developments: 11. Throughout mid-2026, the Mexican government utilized a voluntary agreement to stabilize fuel prices, setting caps of 27 MXN per litre for diesel and 24 MXN for regular gasoline. Compliance fluctuated between 77% in June and approximately 84% by late July. To maintain these levels against international oil price volatility, the Treasury implemented significant IEPS tax subsidies, covering 71.58% of diesel and 38.18% of gasoline taxes. Enforcement and monitoring included an interactive map from Pemex and the Secretaría de Energía to flag non-compliant stations, with notable clusters in Chihuahua, Baja California, and Tamaulipas. In July, Pemex blacklisted 13 stations in Aguascalientes for refusing the diesel cap. While the policy helped contain inflation and kept the basic consumer basket under 910 pesos, some retailers reported squeezed profit margins. As of August 2026, the signing of a new six-month renewal of the voluntary pact has been postponed. While the government intends to finalize the agreement by month-end, fuel distributors have requested shorter terms and a review of profit margins to address rising operational costs and inflation. The proposed renewal aims to maintain the 27 MXN diesel cap and existing reductions in electronic payment commissions. ## Claims - 84 % of diesel stations (8,603) have joined the voluntary price‑stabilization agreement.
