Fitch Ratings downgrades Brazil's bonds to double-B-plus in Dec. 2015, a junk rating from an investment grade rating. The yield on Brazil's 10 year benchmark dollar denominated bond increased to 6.97% from 6.7%. Other emerging markets such as Turkey and South Africa now expect ratings downgrades in 2016 as the U.S. Fed raises interest rates. Standard & Poors downgraded Brazil's sovereign debt to junk status in September 2015. GDP in Brazil declined 4.5% in the third quarter of 2015 from a year earlier. Brazil's currency, the real, declined by 32% in 2015, making it harder for companies that borrowed in dollars to pay off debts. President Dilma Rousseff is facing impeachment proceedings following a corruption scandal at Petrobras.
