The curbs are meant to mitigate potential volatility and provide investors with an opportunity to assess their response to the US tariff barrage that triggered a global market downturn, the exchange said. Thailand was hit by a tariff of 36%, among the highest rates in the region. The Southeast Asian country’s trade surplus with the US totalled US$45 billion ($60.64 billion) last year.
Even before the Trump administration’s levy announcement, Thailand’s stock market was among the world’s worst performers this year as investors headed for the exit amid dwindling corporate profits and a dim outlook for the economy. The benchmark SET index lost 4.3% last week, extending losses this year to almost 20% and hitting a five-year low.
The bourse will conduct continuous market surveillance and recalibrate these measures based on prevailing market conditions, it said in the statement. The temporary measures also cover SET’s other platforms — Market for Alternative Investment and Thailand Futures Exchange Pcl.
