Bonds & Repos Intra-day margin call

Project announcement

Within the scope of its policy to strengthen the Clearing House’s safety and guarantee mechanism, LCH.Clearnet SA aims to introduce an intra-day margin call on its bonds & repos clearing segment.

This additional margin call, based on updated intra-day positions, will improve the accuracy of LCH.Clearnet SA’s risk management on this clearing segment.

It will also be an opportunity to change the margining methodology for same day repos (SDR) and forward repos in their forward period (period between the trading date and the start date).

Same day repos will be margined using the same margining methodology currently applied to end of day positions. SDR transactions will be included in the portfolio to which cross-positions credits will be applied. This will replace the monthly margin call currently in place.

Forward repos margin requirements will be calculated according to a specific algorithm during their forward period. This algorithm will specifically capture the risk of repo rate variation until the start date.

Impact on members


Members are invited to analyse what are the impacts of the introduction of an intra-day margin call on Bonds & Repos on their back-office and treasury procedures.

Members are also advised to liaise with their paying agent on this project, i.e. paying limits may need to be amended in order to cover an intra-day increase of margin requirements.


Project schedule

LCH.Clearnet SA aims to launch this intra-day margin call in Q1 2010. A full project schedule is being elaborated and will be communicated soon.

In order to allow a seamless implementation of the Intraday Margin Call project, members are kindly requested to provide us with a project contact as soon as possible.
