Thailand’s stock gauge tumbled the most in six years as escalating tensions in the Middle East dampened sentiment.

The Stock Exchange of Thailand SET Index closed 5.6% lower on Wednesday, the most since March 2020. Trading in shares was halted for 30 minutes earlier in the day after the gauge fell by the 8% threshold.
