Brazil’s fiscal council Confaz will raise diesel ICMS by 11.1% from February 2027, according to Valor Economico.

According to Valor Economico, Brazil’s fiscal council Confaz approved raising diesel ICMS from R$ 1.17 to R$ 1.30 per litre from February 1, 2027; the 11.1% increase applies to the tax, not the final price. In Mexico, finance secretary Amador Zamora ruled out P-Caps support for state oil company Pemex in 2027, according to El Economista, which reported losses for a third consecutive year. For creditors and suppliers, replacement financing remains unresolved. Valor Economico also reported that the dollar closed the week at R$ 5.44 in Brazil, up 9.04% from the last week before the electoral period, while fiscal adjustment remains under debate. A weaker real raises the local-currency cost of dollar-denominated obligations and equipment for energy projects.
