Brazil's Bovespa slipped 2.48 percent to 49,321.68 points, taking the index to its lowest level since August. The Bovespa, which was one of the world's worst-performing indexes in 2013, is already down more than 4 percent this year.
China's annual consumer inflation slowed more sharply than expected and hit a seven-month low of 2.5 percent in December, data released on Thursday showed. Brazil is China's main source of iron ore.

Across the region, investors showed caution ahead of the release of monthly U.S payroll data on Friday. Any positive news could lead to declines in regional markets as it would raise the chances of the U.S. Federal Reserve further cutting its massive bond-buying scheme.
