The Thailand Industry Sentiment Index (TISI) in April fell to 86.2 points from 89.2 in March due mainly to the global oil price surge, driven by the prolonged Russia-Ukraine war, and higher inflation.
The drop in the TISI came following its hike in March, the highest rise in 25 months, according to the Federation of Thai Industries (FTI).
"Factors that directly impacted industrial confidence are increasing production costs resulting from higher energy and raw material prices as well as expensive logistics costs," said Kriengkrai Thiennukul, chairman of the FTI.
