Casey describes the crucial policy errors in Brazil with over spending and lack of transparency in the years leading to the crisis in 2014-2015. Brazil raised interest rates half a percentage point in May 2015 to 13.25%. Inflation was at 8.13% in Brazil in March 2015. Brazilian companies have large dollar denominated debt accumulated during the boom years which needs to be refinanced as its currency the real declines. With current policies economic growth is likely to continue at 0-1%. Russia made policy errors with the departure of Kudrin as finance minister for Putin's second term as president. Policies to attract foreign investment, controlling military expenditures, and continuing growth were reversed as Russia took positions on Ukraine that led to western sanctions, capital outflows, and a sharp decline in the ruble. By May 2015 the ruble and oil prices had recovered from lows, but the ruble was still 35% below the level in June 2014, and the oil prices were still only two thirds of the peak in 2014.

India's central bank chief, Rajan, favors a lower inflation target of 4%, with fluctuations of 2% up or down. Lower inflation is critical for India to achieve higher growth rates. The World Bank lowered the rate of growth in the global economy but kept the rate of growth of 6.4% for India unchanged. Rajan also favors creating a more formal system for setting rates, with a committee like the Open Market Committee in the U.S. deliberating over the different factors for such a decision. Rajan was a professor at the University of Chicago, and chief economist at the IMF, before joining the central bank. Central bank policies have helped stabilize India's currency, the rupee. The lower cost of oil for India with an oil import bill of $100 billion is a big boost for economic growth. For the global economy this comes at a time when China's growth rate is slowing to below 7%.
