Application of Intraday Additional Margin Call

(August 11, 2005)


Tokyo Financial Exchange (TFX) applied the Intraday Additional Margin Call of Interest-rate etc. Financial Futures today as the Three-month Euroyen futures market soared, for first time since April 17, 2000..

・What is the Intraday Additional Margin Call?

TFX usually calculates margin requirements based on the SPAN® margin system, which applies only to a certain range of price fluctuations of futures contracts traded under a normal circumstance.
However, when the market moves out of this set range, TFX determines the provisional settlement price for the futures contracts at the end of its morning session (11:30 am Tokyo Time), and calculates intraday additional margin requirements based on positions carried by a member at the time. TFX then requests additional deposits from a member whose margin deposits are less than the amount required by the Intraday Additional Margin Call.

・When is the Intraday Additional Margin Call triggered?

The Intraday Additional Margin Call is triggered when changes in price of the leading contract month (currently June 2006 contract) traded at TFX exceed a range of price fluctuations set by TFX (currently 4.5 ticks, or 0.045%) at 11:25 am Tokyo Time, 5 minutes before the end of its morning session.
