SET launches rules on market disruption and amends circuit breaker rule 
effective April 15

BANGKOK, April 13, 2020 - The Stock Exchange of Thailand (SET) announced 
regulations on actions to cope with market disruption, through the board of
governors' authority to temporarily introduce necessary and urgent measures to
remedy the impact of such disruption.  In addition, SET has also permanently
revised the circuit breaker (CB) rule by increasing trigger levels of the CB to
three from two.  These regulations have been reviewed by participating
stakeholders and approved by the Securities and Exchange Commission (SEC) and
they will be effective starting from April 15, 2020.

SET President, Pakorn Peetathawatchai, said that given the current COVID-19 
pandemic which has caused high volatility and unusualness of trading, it is
necessary to impose measures in order to effectively react to any incidents that
may affect the SET's operations.  Rules on market disruption will reduce the
adverse impact and the new CB trigger levels will enable investors to better
analyze information for investment decision.

The summary of these regulations are as follows:
1.    Regulations on actions to cope with market disruption
SET's board of governors can make a decision to temporarily implement any 
measures to remedy impact caused by market disruption events, and can specify
effective duration as deemed appropriate for the situation. (Details as shown in

2.    Permanent Revision of circuit breaker rule by increasing trigger levels to

The recent revised circuit breaker rule since March 18, 2020 to three level will
be implemented permanently to give more opportunity for investors to analyze
information for investment decision, and in line with international practices.

Current
Level 1    Trigger value -10%    Halt action 30 mins
Level 2    Trigger value -20%    Halt action 60 mins

Level 2    Trigger value  -15%  Halt action    30 mins
