By Brazil Stock Guide — Brazil’s government has extended a 12% tax on crude oil exports through December 31, maintaining a measure designed to support domestic energy security and generate federal revenue even as international oil prices retreat sharply following the U.S. midterm elections.
The extension was approved by the executive committee of Brazil’s Foreign Trade Chamber on Thursday, November 5, and published in the Federal Official Gazette on Friday. Resolution takes effect on November 7 and extends the levy introduced in July.
The tax has become a significant source of government revenue. According to Federal Revenue Service figures, Brazil collected R$12.87 billion (approximately $2.4 billion) from the levy between January and September 2026, including R$2.94 billion (about $550 million) in September alone.
The government introduced the measure amid disruptions to global oil supplies caused by the conflict involving Iran and the United States. Officials have argued that taxing crude exports can help maintain adequate conditions for domestic refining and reduce the risk of fuel shortages, while providing additional revenue to offset energy-related subsidies and tax relief.
The extension comes as global oil markets undergo a sharp correction. Brent crude fell 8.7% on Wednesday to $94.62 a barrel after Democrats won control of both chambers of the U.S. Congress, raising expectations that political pressure on President Donald Trump could encourage negotiations to de-escalate the conflict with Iran.
By Friday, Brent was on track for a weekly decline of approximately 16%, its steepest percentage fall since the onset of the Covid-19 pandemic in 2020. Despite the decline, continued attacks on oil tankers in the Persian Gulf and the Strait of Hormuz have sustained concerns about supply disruptions.
Revenue Benefits and Industry Costs
For the Brazilian government, the export tax serves both fiscal and regulatory objectives. Revenue from the levy has helped finance measures intended to cushion domestic consumers from higher energy costs, while the tax also seeks to encourage domestic processing of crude oil.
Oil producers, however, face additional costs on international sales. Companies with substantial exposure to crude exports, may see their export revenues affected depending on production volumes, international prices and commercial arrangements.
Industry representatives have questioned the policy, arguing that the levy reduces the competitiveness of Brazilian crude and may discourage investment in exploration and production. They also contend that Brazil’s refining capacity limits the extent to which crude otherwise destined for export can be absorbed by domestic facilities.
The recent decline in international oil prices adds another consideration for producers. Lower benchmark prices reduce the value of exported barrels, while the 12% tax continues to apply to their export value, adding pressure to margins.
For the government, the challenge is to balance energy security and fiscal needs against the competitiveness of Brazil’s oil industry, one of the country’s most important sources of export earnings.
The new resolution does not change the tax rate or introduce additional conditions. It extends the existing measure through the end of 2026, leaving any decision on its continuation in 2027 to a subsequent government assessment.
