OpenGamma And SIMM Provide Value To Market Participants
By Marc Henrard
At the start of September, the mandatory bilateral margin rules for derivatives came into force in the US, Canada and Japan. Even if some jurisdictions decided to postpone their go-live, daily initial margins calls are now a reality for the main derivatives dealers.
If all financial institutions were using their own internal methodology for margin calculation, it would rapidly become a major problem as each firm would need to replicate all of their counterparties’ methodologies to validate margin calls. To reduce potential dispute issues arising from this situation, ISDA proposed SIMM™ (Standard Initial Margin Methodology) that could be used by all financial institutions impacted by the regulation. The methodology itself was developed by the ISDA WGMR and based on the standard Sensitivity Based Approach of the BCBS “Standards: Minimum capital requirements for market risk” (previously known as FRTB) .
Over the past few years, OpenGamma has been working with market participants on the calculation of Initial Margin requirements. Extending our offering to the bilateral space by implementing SIMM made a lot of sense. Since the publication of the first documents by ISDA, we have been keeping up-to-date with the changes to the methodology as it was being refined by the industry and have performed analysis on the impact for financial institutions .
In this blog, I would like to describe some of the SIMM-related initiatives OpenGamma have been involved in recently.
The library we have developed to implement SIMM is very lightweight (code is less than 300KB). It was designed to be integrated in other systems and with other libraries. For the projects below, we associated it with our open-source risk management library, Strata, for the computation of sensitivities.
We pride ourselves in our technology and derivatives expertise, and have been using both our open-source analytics (for the calculation of sensitivities) and SIMM implementation to deliver value to a variety of market participants:
I will be speaking about these initiatives and SIMM at the ISDA Annual Conference on September, 20th. Please come by and say hello during the lunch break.
