International issues took on larger significance for the U.S. Federal Reserve in September 2015 as it looked at a small increase in interest rates. Schwartz points to the memories of the 1997 emerging market crisis and how fragile economies like Mexico were adversely impacted by rising rates in the U.S.. Mexico needed a large bank bailout and contagion spread to other countries. Kenneth Rogoff says the risks are real with declining commodity prices and falling currencies of emerging markets such as Brazil, Indonesia and Russia. Ripple effects would carry over to India and other countries. The sharp slowdown in the Chinese economy in the second half of 2015 was too recent for the Fed to take any sort of risk in September 2015.
