Industrial production is expected to expand by 11.3 percent this year and by 5 percent in 2011 The faster-than-expected growth has become a concern for the government and analysts because it could lead to imbalances of the economy. Brazilian authorities have already started considering measures in case of economic overheating. The survey also expects a surplus of 15 billion U.S. dollars this year in the country's foreign trade, and an inflow of 36.5 billion dollars of foreign direct investments. The country's current account deficit is now projected to reach 48.5 billion dollars in 2010 and 57.9 billion dollars in 2011.
