Brasília's Federal Court granted an injunction on August 27 suspending the 12% tax on crude oilOilAssetEnergy commodity whose price reflects supply, demand, inventories, logistics and geopolitical risk.Open in the Market Map ↗ exports for companies affiliated with Abep, in a ruling by Judge Diego Câmara of the 17th Court, according to Agência Brasil, Brazil Journal, g1 and Poder360. The request to refund amounts paid since July was denied.
The same day, the Executive Management Committee of the Foreign Trade Chamber (Gecex-Camex) extended the levy for another 60 days starting September 8, running through November, according to Agência Brasil and Brazil Journal. The tax was created by provisional measure in March 2026 to offset diesel tax relief during the Middle East escalation.
In the ruling, the judge wrote that the government could not use Camex to renew the effects of a provisional measure never voted by Congress, calling it a circumvention of due legislative process, according to Brazil Journal. From January through July the tax collected R$ 7.98 billion, according to Poder360 and Correio Braziliense.

Market read-through
For Abep-affiliated oilOilAssetEnergy commodity whose price reflects supply, demand, inventories, logistics and geopolitical risk.Open in the Market Map ↗ exporters, the injunction removes a 12% cost on shipments in the short run — immediate margin relief while it stands; Camex's extension, however, keeps the levy alive for the rest of the sector and signals the government will contest every step.
For the fiscal picture, the tax has become a relevant revenue source (R$ 7.98 billion through July) just as the central government returned to a monthly surplus; a definitive strike-down would force revenue recomposition or more pressure on the target.
Portfolio impact
02Suspending the 12% tax for Abep members improves export margins; Camex's extension limits the relief's reach and keeps legal risk alive.
Relief is immediate only for the injunction's beneficiaries; the positive direction reflects the cost reduction while the ruling stands.
What would change the view: The effect depends on the injunction surviving an AGU appeal and possibly extending to non-members; a merits reversal restores the cost.
Suspending the charge for part of the exporters cuts a revenue stream worth R$ 7.98 billion through July, squeezing the primary result's margin.
The negative direction concerns fiscal revenue, not a traded asset — the channel is the primary result and the fiscal risk premium.
What would change the view: The impact grows if the ruling extends to the whole sector or is upheld on the merits; a judicial reversal eliminates it.
Direction is an explanatory hypothesis, not a forecast or recommendation.
