The Eurasia Group publishes a composite index, Global Political Risk Index (GPRI), that assesses political risk in 24 investable emerging markets by examining 20 indicators grouped into four categories - government, society, security and economy. All indicators are scored on a scale of zero to 100 and higher numbers indicate greater political stability, meaning a greater capacity to respond to shocks and crises. Here is the latest GPRI index as on September 2009
Here is the list of the Group's top ten risks for 2010. Its list of ten countries with fat tail (the tail ends of the distribution curves that measure country-level political risks and vulnerabilities are thickening) risks (on their national-level politics) are Pakistan, Ukraine, Russia, Mexico, Nigeria, Turkey, Argentina, UAE, Japan, Poland.
