SECTION 4 Initial margin models

Article 14 General requirements

  1. (1)

    Where a counterparty uses an initial margin model, that model may be developed by any of, or both, counterparties or by a third-party agent.

    Where a counterparty uses an initial margin model developed by a third-party agent, the counterparty shall remain responsible for ensuring that that model complies with the requirements referred to in this Section.

  2. (2)

    Initial margin models shall be developed in a way that captures all the significant risks arising from entering into the non-centrally cleared OTC derivative contracts included in the netting set, including the nature, scale, and complexity of those risks and shall meet the following requirements:

    1. (a)

      the model incorporates risk factors corresponding to the individual currencies in which those contracts in the netting set are denominated;

    2. (b)

      the model incorporates interest rate risk factors corresponding to the individual currencies in which those contracts are denominated;

    3. (c)

      the yield curve is divided into a minimum of six maturity buckets for exposures to interest-rate risk in the major currencies and markets;

    4. (d)

      the model captures the risk of movements between different yield curves and between different maturity buckets;

    5. (e)

      the model incorporates separate risk factors at least for each equity, equity index, commodity or commodity index which is significant for those contracts;

    6. (f)

      the model captures the risk arising from less liquid positions and positions with limited price transparency within realistic market scenarios;

    7. (g)

      the model captures the risk, otherwise not captured by other features of the model, arising from derivative contracts where the underlying asset class is credit;

    8. (h)

      the model captures the risk of movements between similar, but not identical, underlying risk factors and the exposure to changes in values arising from maturity mismatches;

    9. (i)

      the model captures main non-linear dependencies;

    10. (j)

      the model incorporates methodologies used for back-testing which include statistical tests of the model's performance;

    11. (k)

      the model determines which events trigger a model change, calibration or other remedial action.

  3. (3)

    The risk management procedures referred to in Article 2(1) shall ensure that the performance of the model is monitored on a continuous basis including by back-testing the model at least every 3 months.

    For the purposes of the first subparagraph, back testing shall include a comparison between the values produced by the model and the realised market values of the non-centrally cleared OTC derivative contracts in the netting set.

  4. (4)

    The risk management procedures referred to in Article 2(1) shall outline the methodologies used for undertaking back-testing, including statistical tests of performance.

  5. (5)

    The risk management procedures referred to in Article 2(1) shall describe what results of the back-testing would lead to a model change, recalibration or other remediation action.

  6. (6)

    The risk management procedures referred to in Article 2(1) shall ensure that counterparties retain records of the results of the back-testing referred to in paragraph 3 of this Article.

  7. (7)

    Counterparties shall provide all the information necessary to explain the calculation of a given value of the initial margin model to the other counterparty in a way that a knowledgeable third party would be able to verify that calculation.

  8. (8)

    The initial margin model shall reflect parameter uncertainty, correlation, basis risk and data quality in a prudent manner.
