The consumer confidence index in September declined for the sixth months in a row, according to the University of Thai Chamber of Commerce.
At 77.9, the index was the lowest in 11 months, since November 2012.
Thanavath Phonvichai, director of the university's economic study centre, attributed the fall to low confidence in economic condition particularly the export slump, persistently high cost of living, flood, and global volatility as well as political situation.
He expected the confidence to remain low until the middle of the fourth quarter, as there is no sign of economic recoveries. He noted that if the political chaos can be neutralised soon and if the government can spend more, confidence should pick up in the fourth quarter.
