Bangkok - Thailand's stock market regulators enforced a circuit-cut on the market Friday after the index fell more than 10 per cent.

The Stock Exchange of Thailand (SET) index hit 449.91, down 50.08 points, or 10.02 per cent, shortly after reopening mid-day, prompting authorities to close trading for half an hour in keeping with the bourse's regulations.

The bourse was reopened after 30 minutes. (dpa)
