· The increase of R$ 0,10 in the liter of gasoline in 2026 came exclusively from the decision to raise ICMS, approved by the National Council of Fiscal Policy (Confaz), which is composed of the finance secretaries of the states.
· ICMS revenue from fuels is vital for states, reaching over 25% of total revenue from this tax in some states. Reductions impact state services such as health and security.
