Prudential Regulation Authority Rulebook

1.

An institution that acts as a clearing member and, in that capacity, acts as a financial intermediary between a client and a CCP shall calculate the own funds requirements for its CCP-related transactions with that client in accordance with Sections 1 to 8 of this Chapter, with Section 4 of Chapter 4 of this Title and with Title VI, as applicable.

2.

Where an institution acting as a clearing member enters into a contractual arrangement with a clientt of another clearing member that facilitates, in accordance with Article 48(5) and (6), of Regulation (EU) No 648/2012, the transfer of positions and collateral referred to in Article 305(2)(b) for that client, and that contractual agreement gives rise to a contingent obligation for that institution, that institution may attribute an exposure value of zero to that contingent obligation.

3.

Where an institution that acts as a clearing member uses the methods set out in Section 3 or 6 of this Chapter to calculate the own funds requirement for its exposures, the following provisions shall apply:

1. (a) by way of derogation from Article 285(2), the institution may use a margin period of risk of at least five business days for its exposures to a client;
2. (b) the institution shall apply a margin period of risk of at least 10 business days for its exposures to a CCP;
3. (c) by way of derogation from Article 285(3), where a netting set included in the calculation meets the condition set out in point (a) of that paragraph, the institution may disregard the limit set out in that point, provided that the netting set does not meet the condition set out in point (b) of that paragraph and does not contain disputed trades or exotic options;
4. (d) where a CCP retains variation margin against a transaction, and the institution's collateral is not protected against the insolvency of the CCP, the institution shall apply a margin period of risk that is the lower of one year and the remaining maturity of the transaction, with a floor of 10 business days.

4.

By way of derogation from point (i) of Article 281(2), where an institution that acts as a clearing member uses the method set out in Section 4 to calculate the own funds requirement for its exposures to a client, the institution may use a maturity factor of 0.21 for its calculation.

5.

By way of derogation from point (d) of Article 282(4), where an institution that acts as a clearing member uses the method set out in Section 5 to calculate the own funds requirement for its exposures to a client, that institution may use a maturity factor of 0.21 in that calculation.

6.

An institution that acts as a clearing member may use the reduced exposure at default resulting from the calculations set out in paragraphs 3, 4 and 5 for the purposes of calculating its own funds requirements for CVA risk in accordance with Title VI.

7.

An institution that acts as a clearing member that collects collateral from a client for a CCP-related transaction and passes the collateral on to the CCP may recognise that collateral to reduce its exposure to the client for that CCP-related transaction.

In the case of a multi-level client structure, the treatment set out in the first subparagraph may be applied at each level of that structure.
