The head of Brazil’s oil giant Petrobras, Pedro Parente, has resigned, following a nationwide strike by lorry drivers that caused huge disruption.
The strike against diesel prices, which ended this week, caused major shortages in the country.
Many of the protesters blamed Mr Parente for rising costs, after the company stopped subsidising fuel prices for its domestic consumers.
However, Petrobras gave no specific reason for the resignation.
In his resignation letter to President Michel Temer, Mr Parente said the strike challenged the pricing policy he had implemented.
Mr Parente said his role “as CEO had stopped being positive” and the government needed to consider “alternatives” to its pricing policy going forward, according to Reuters news agency.
Two years ago, former energy minister Mr Parente pegged the price of fuel in Brazil to international oil prices, which have since almost doubled.
In January, the company agreed to pay almost $3bn (£2.18bn) to settle a class action suit in the United States, after investors said their holdings were damaged by a corruption scandal facing the firm.
Brazil’s government had said it will not use Petrobras to subsidise fuel.
But the departure of Mr Parente has led to some speculation that Brazil may go back to its old fuel pricing policy of subsidies for those from low-income backgrounds.
Shares fell by more than 20% following his resignation on Friday.
Petrobras’ paradox
What can a country do against rising global oil prices? That’s a question Brazil has been grappling with for about a decade.
From 2011 to 2016, Petrobras offered great subsidies to consumers, which helped keep Brazil’s inflation down and secured job creation.
But it suffered huge losses that threatened the company’s long-term prospects.
Then in 2016 came Pedro Parente and the company took a U-turn. All subsidies were lifted and fuel costs began to oscillate according to global prices.
Its financial credibility was restored but diesel consumers – particularly lorry drivers – felt a shock when global oil prices shot up.
Mr Parente’s resignation suggests some form of government intervention in prices will come.
But few investors will be pleased with the idea of purchasing shares in a company that is focused on tackling inflation and unemployment, rather than just producing oil.
