Petrobras lowers its domestic diesel prices starting June 1, aligning with a government subsidy plan in Brazil. Bloomberg reports the reduction begins Monday as part of an effort to shield consumers from the impacts of the war in the Middle East. The Rio Times details the size and timing of the change: Petrobras cuts refinery diesel price by R$0.3515 per litre, a 9.59% decrease, taking the price from R$3.65 to R$3.30. The Rio Times attributes the move to the start of a federal fuel support measure. A provisional measure issued May 30 authorizes an economic subsidy of R$1.12 per litre for road-diesel producers and importers. The outlet says the discount is designed to offset the cost effect of the subsidy as it flows through the supply chain. Both sources characterize the price adjustment as a response to a broader policy aimed at reducing the final burden on consumers, with Petrobras implementing the change at the refinery level.
