Bolsonaro has also said he has no plans to reinstate the taxes next year if reelected, so mills would be expected to shun ethanol and produce more sugar, which could depress global prices for the sweetener. Lula's Workers Party latest run at the helm with former President Dilma Rousseff from 2011 to 2016 brought havoc in the sugar and ethanol sector, as the government kept gasoline prices artificially low to stem inflation. Equity research teams at Citi and investment bank BTG Pactual said all those factors increased risks for the financial performance of sugar and ethanol companies.
