Businesses are asking for more economic stimulus measures from the government to help support the economy in the second half and move the country towards a recovery trend, says the Federation of Thai Industries (FTI).
Chairman Chen Namchaisiri said the most pressing issue is weak purchasing power.
"We are worried about rising household debt that will prevent consumers from spending and that would affect investment and also confidence as the whole," Mr Chen said.
His comment echoed the findings of Kasikorn Research Centre, which said that more than half of Thai households were worried about their cost of living, rising debts, and income levels, with those making 15,000 baht or less a month more stressed over debt than income.
K-Research's survey of the economy found that 53% of respondents said they were worried their household income, which they say has remained the same or is even lower than it was a year or so ago, is not enough to cover their costs and debts.
Mr Chen said the FTI demanded the government issue some economic stimulus measure to keep the recovering momentum to push Thai economy to move forward on the rising trend in the second half.
He said the stimulus package could come in the form of tax deductions, tourism support or other measures to boost people's spending power.
Previously, the cabinet rejected a proposal of the Tourism Authority of Thailand (TAT) to allow more tax breaks from tourism-related activities.
According to the TAT's initial proposal, tourists who spend during the final quarter of this year would be allowed to claim a personal income tax deduction of 10,000-50,000 baht, depending on the area visited.
The FTI reported that the Thai Industries Sentiment Index fell for the fourth consecutive month in July to 83.9 from 84.7 in June due to the domestic economic slowdown, with excessive rains and floods dampening spending sentiment.
Mr Chen said the recent flood that hit the northeastern and southern regions was a key factor hindering transport, logistics and export of major commodities.
