Architecture

ICE Risk Model 2

ICE Risk Model 2 (IRM 2) is ICE's portfolio-based margin model, designed to calculate margin requirements at the portfolio level. By capturing the hedging and diversification benefits that exist across positions, IRM 2 delivers more capital-efficient, risk-appropriate margin for participants across energy contracts and ICE Clear U.S. interest rate futures, with ICE Clear Europe interest rates subject to regulatory approval.

Benefits of IRM 2


IRM 2 is a portfolio-based margin model which offers full diversification benefit based on accurate estimate of the portfolio risk. The model is based on filtered historical simulation and is responsive to changing market conditions. IRM 2 includes model features which provide stability through different volatility regimes and avoids big step margin changes through its anti-procyclical add-on. The model is resilient against stress events, correlation breakdown and adjusts for seasonality where appropriate.

From the operational standpoint, IRM 2 offers a wider range of tools providing full transparency of margin. Enhanced analytics supported by the latest technology will be made available as part of the IRM 2 implementation project. The model architecture that underpins IRM 2 offers both scalability and fully automated margin update process.
