Annual manufacturing output in September likely declined at a slower pace than in the previous month, a Reuters poll showed on Monday.
The median forecast from eight economists polled was for the manufacturing production index to decline 2.05% in September from a year earlier. In August, output dropped 4.4%, dragged down by lower production of cars, electronics and rubber products.
Industrial goods account for about 80% of Thailand's total exports, a key economic driver, which declined 1.39% in September from a year earlier.
Exports have been affected by global trade tensions and the strength of the baht, Asia's best performing currency this year.
