BRASILIA, Aug 18 (Reuters) - Brazil’s Special Treasury and Budget Secretary Bruno Funchal said on Wednesday that, with the economy growing, the debt to GDP ratio is projected to stabilize around 81.2%. Speaking to the congressional budget committee, Funchal said 2021 was a tough year, but Brazil’s fiscal situation is evolving positively now. The challenge he said, will be to keep public debt stable as inflation pushes up interest payments.
