The sugar and ethanol sector is once again facing an old scenario, marked by tight margins and high debts. After years of prosperity, part of the mills enters the new cycle with high indebtedness and little capacity to react to the drop in sugar and ethanol prices. According to finance professor Thiago Gil, the current scenario combines cheaper gasoline, increased corn ethanol production, and still high interest rates, a combination that pressures profitability and threatens to repeat the debt renegotiations seen in 2015 and 2016.
