In South Korea, The Economic Sentiment Index (ESI) is a composite of the BSI (Business Survey Index) and the CSI (Consumer Survey Index). The index is compiled to comprehensively grasp the private sector perception of economic conditions, including the sentiments of both businesses and consumers. An ESI reading above 100 is interpreted as meaning that economic sentiment in the private sector, including that of both businesses and consumers, is on a level better than past averages (and vice versa when the reading is below 100), since the ESI is constructed so that it is distributed around a long-term mean of 100 and a standard deviation of 10.
