How smarter IM calculation can minimize capital allocation

A common challenge for our customers is the substantial amount of capital consumed by the clearing process. A particular frustration is the funding costs associated with posting Initial Margin to the clearing houses for the entire life of the trades.

Technology for our Time

One of the benefits of being a relatively new vendor in the fintech space is that customers and prospects can be refreshingly open with their views about the status quo. They frequently tell us that traditional vendors are still not meeting the industry’s needs, which is perplexing as it has always seemed pretty clear to us how our sector needs to adapt – in fact, we’ve built our whole business around it.

  • Forward IM for CCP's

    The objective of Forward Initial Margin calculations is to provide clearing members with an indication of the risk and funding costs associated with cleared trades. The requirement for Forward IM is driven by the realisation that Initial Margin needs to be funded for the entire life of the trade and that, by nature, the Initial Margin calculations account for risk offsets with trades of different maturities that will roll off the portfolio. In this paper, we describe how forward IM for CCP's can be estimated and give examples with different approaches to the forward, and different CCPs.

  • Smile Interpolation and Extrapolation

    In this paper, we review techniques for smile interpolation and extrapolation, and compare numerical results across the different methodologies. Examples of smile interpolation include spline interpolations, mixed lognormal model and SABR model together with various volatility approximation formulas. For smile extrapolation, we introduce two methods: shifted lognormal model and elementary-function-based approach.
