According to the latest Research Center for Taiwan Economic Development poll, Taiwan’s Consumer Confidence Index (CCI) fell 7.07 points year on year to 67.81 points in May, a two-year low.

According to the survey report released this week, the index declined 3.96 points from April, while all six sub-indices plummeted.

The CCI is made up of six sub-indices that measure consumers’ expectations for six aspects of the economy over the next six months, including stock market investment, consumer pricing, and household economic situations.

A rating of 100 to 200 points implies optimism, whereas a reading of less than 100 indicates pessimism.

According to the research, the sub-index for stock market investment fell by 8.7 points from April to 32.9 points, followed by the sub-index for durable goods purchases, which fell by 5.1 points to 114.8 points.
