Thailand Clearing House Co Ltd (TCH) will temporarily raise trading margins or impose the so-called Super Margin for oil, silver and US dollar futures traded on the Thailand Futures Exchange (TFEX) on April 12 ahead of the Songkran holiday.
Investors are asked to prepare extra cash for the long holiday because foreign markets will operate normally.
The Super Margin is intended to cover risks from price volatility that may occur while the foreign markets remain open.
The initial margin for silver futures will be raised to 9,880 baht and its maintenance margin will be 6,916 baht per contract, while the initial margin for oil futures will be 19,380 baht and its maintenance margin will be 13,566 baht per contract. For US dollar futures, the initial margin will be increased to 684 baht and the maintenance margin will be 478.80 baht per contract.
The margin requirements will return to normal on April 17 when the local market reopens.
Investors can withdraw their excess margins on that date, said TFEX managing director Kesara Manchusree.
