Margining Requirements for Futures(except for STF)
Determination of Margin Requirements
Clearing margin for index futures =
Closing price of the underlying spot index × Value per index point × Risk coefficient
Clearing margin for 10-Year Government Bond futures =
Face value × Price quoted per NTD 100 face value × Risk coefficient ÷ 100
Clearing margin for Commodity futures =
Commodity futures price × Contract size × Risk coefficient
Clearing margin for FX futures =
FX futures price × Contract size × Risk coefficient
The calculation of the risk coefficient of margins for futures contracts is based on the price movements of the underlying spot within a certain period, anti-procyclicality and other possible factors with at least a 99 percent confidence interval to cover two-day premium price variation.
