Brazil’s federal debt rose to 3.88 trillion Reais ($1.03 trillion) in December, up 8.9% from 3.56 trillion Reais a year earlier, and is expected to rise further this year, the Brazilian Treasury said. The Treasury predicts public debt this year will swell to somewhere between 4.1 trillion and 4.3 trillion Reais, the upper end of which would represent an increase of almost 11%, it outlined in its annual financing plan.
