SET revises rules to accommodate DWs with foreign stocks as underlying assets

BANGKOK, December 13, 2021 - The Stock Exchange of Thailand (SET) has extended 
the types of underlying assets for derivative warrants (DWs) to cover foreign
stocks and adjusted its ceiling & floor limits criteria for Foreign Underlying
linked DWs. The revised regulations go into effect from Dec 13, 2021 onwards.

SET President Pakorn Peetathawatchai said that SET has amended DW regulations by
adding foreign stocks to the underlying assets on top of local stocks and
indices, as well as foreign indices. To keep pace with the move and to be more
appropriate, the ceiling & floor limits for DWs on foreign underlying assets
have been set at not over 20 times the DW closing prices on the previous day. In
addition, SET has stepped up regulatory oversight of DWs with irregular trading
in the similar practice to SET's supervision on stock trading in order to
mitigate risks for investors. SET will announce the DWs that are subject to
Market Surveillance Measure List via this website: In addition,
SET has also adjusted the criteria on information disclosure to make underlying
asset information accessible to investors to help them make investment

From January to November 2021,190 new series of DWs with foreign underlying 
assets were traded on SET, up 13 percent from a year earlier. The daily trading
value of DWs averaged THB 472 million (approx. USD 14.12 million), rising 16
percent year-on-year. The trading of DWs that use foreign indices as underlying
assets makes up 5.5 percent of SET's overall DW trading value at THB 8.58
billion per day on average.

Information on DWs and those with foreign underlying assets is available at
