The inflation index for Brazil went up by 5.99% in January 2011, compared to the prior year. Prices went up by 0.83% in January, compared to December 2010. Brazil's central bank surveys show rising expectations for inflation in the country. This creates pressures for the central bank to raise interest rates above the existing 11.25% overnight interest rate, which is already one of the highest worldwide. Higer rates would worsen the impact on the currency as it accelerates volatile money flows into Brazil. The soaring Braziling curency is widely considered to be highly overvalued and a volatile currency hurts Brazil's growth prospects. Brazil's government spending under the Luis Da Silva presidency was increasing rapidly and cuts in spending are expected, though there is skepticism that the incoming President Rousseff will control spending.
