# Brazil energy sector regulatory and pricing volatility > Live situation record from CLSTR: https://clstr.news/situations/brazil-energy-sector-regulatory-and-pricing-volatility > Updated: 2026-09-10T21:24:34.000Z. Sources: 15. Developments: 2. The Brazilian energy sector has faced increased regulatory and operational uncertainty following recent government and corporate actions. In early September, the federal government reinstated a 12% export tax on crude oil for a 60-day period. This decision, made by Camex, is expected to impact the profitability of major producers such as Petrobras and PRIO. Industry representatives have expressed concerns that such taxation changes may hinder long-term investment due to a lack of regulatory predictability. Petrobras has also faced scrutiny regarding its pricing policies. Following a communication error, the company announced and then quickly rescinded a planned gasoline price hike for distributors. While the company maintained the average sale price at R$ 3.05 per liter, analysts have described the incident as a “governance scratch,” raising concerns about potential government intervention and the company’s independence. Amidst this volatility, Petrobras has moved to expand its natural gas operations, signing a contract with Voqen Energia valued at approximately R$ 1.85 billion to support various transport systems through 2029. ## Timeline ### 2026-09-10: Fuel markets see volatility in Portugal and Brazil Fuel prices in Portugal are set to see diesel rises and gasoline drops amid tax criticisms, while Petrobras in Brazil faces governance concerns following a retracted gasoline price adjustment. 13 sources. https://clstr.news/cluster/petrobras-reverses-gasoline-price-hike-following-market-concerns ### 2026-09-03: Brazil reinstates crude oil export tax affecting Petrobras and PRIO Brazil is reinstating a 12% export tax on crude oil for 60 days starting September 8, impacting companies like Petrobras and PRIO and raising concerns over regulatory stability. 2 sources. https://clstr.news/cluster/brazil-reinstates-crude-oil-export-tax-affecting-petrobras-and-prio --- Cite as: Brazil energy sector regulatory and pricing volatility.
