1 Introduction

Central counterparties (CCPs) are post-trade, pre-settlement market infrastructure. They clear contracts of many kinds by becoming buyer to every seller and seller to every buyer. A combination of legal techniques including novation, netting and asset-backing enables CCPs to assume market participants’ counterparty credit risk and act as a ‘shock absorber’ by mutualising losses in times of market failure. For this reason, CCPs can be thought of as ‘legal devices’, where the underlying legal techniques both explain and constrain how clearing services work.Footnote 1

This legal perspective helps to evaluate the robustness of market infrastructure like CCPs. For instance, it offers a way of exploring the interaction between different legal techniques, and how those techniques may be complicated by exogenous factors like new financial markets regulation. Building on this insight, this article offers an analysis of the interaction between two of a CCP’s key risk management tools, being selective membership and collecting margin, and the new regulatory regime for over-the-counter (OTC) derivatives.Footnote 2 The central thesis developed here is that reforms designed to address one lesson of the financial crisis (the risk that built up in the OTC derivatives markets) must now address another such lesson (namely, the risk associated with client assets).

The analysis is developed in three Sections. Section 2 discusses the regulatory context and explains the newly enhanced role for CCPs in the ‘perimeter-changing measures’Footnote 3 implemented worldwide since the financial crisis. Section 3 turns to the question of the interaction between new regulation and access to CCPs. It starts by cautioning that the introduction of compulsory clearing potentially conflicts with CCPs’ autonomy because such a rule is premised on all non-exempt market participants being able to gain access to clearing services. As the article demonstrates, this conflict is mitigated, but not solved, by the possibility of alternative routes to clearing services, through a CCP member. As the article explains, this means that one of the effects of the new regulatory regime for OTC derivatives will be to increase the importance of the legal structures behind ‘client clearing’ arrangements. With this in mind, Sect. 4 of the article explores how client clearing complicates the provision of margin to CCPs. In particular, this part of the article argues that CCP members which clear for clients are subject to a patchwork of rules, as the clearing and client assets regimes sit awkwardly together. The interaction between the European clearing regime and the UK rules on client money, recently overhauled as a direct result of the financial crisis, are considered by way of example. The article concludes that the interaction between new regulations mandating clearing and the underlying law needs to be addressed at EU level in order to safeguard the functions that attracted regulators to clearing in the first place.

2 The Regulatory Context

In the immediate aftermath of the global financial crisis, the G20 quickly turned its attention to reforming the OTC derivatives markets. This ambitious use of political capital reflected the fact that various types of these privately traded derivatives, especially credit default swaps (CDS), were implicated in disasters like the near-collapse of AIG.Footnote 4 Accordingly, the statement issued after the G20’s September 2009 Pittsburgh meeting included the declaration that all ‘standardized OTC derivatives contracts’ should be ‘traded on exchanges or electronic trading platforms, where appropriate’ and cleared through CCPs by ‘end-2012’.Footnote 5 These measures have subsequently become ‘one of the defining features of the G20’s reform programme’Footnote 6 seeking to increase financial stability by addressing the concentration of risk, to increase market resilience, and to improve the transparency of these opaque markets.Footnote 7

One of the central planks of the G20 reform agenda is that standardised OTC derivatives must be cleared through a CCP, rather than remaining as private, bilateral contracts between counterparties, where each assumed the credit risk of the other’s default. Why would the G20 seek to impose this particular reform? One reason identified in the literature is that CCPs performed effectively during the crisis, even being described as the ‘unlikely heroes’ of the collapse of the Lehman Brothers group.Footnote 8 This high-profile demonstration of the benefits of CCPs in contributing to market resilience seems to have helped influence the G20’s decision to make the clearing of eligible contracts mandatory.Footnote 9

The G20’s agenda has triggered complex legislative activity worldwide, but, despite the stated deadline of ‘end-2012’, it has not been fully implemented in any jurisdiction yet.Footnote 10 In the EU, this new regulatory regime is to be found in the European Market Infrastructure Regulation (EMIR)Footnote 11 and the 2014 MiFID II/MiFIR regime.Footnote 12 The ‘clearing obligation’ itself is found in Article 4 of EMIR, which is fleshed out in Commission Delegated Regulation 149/2013.Footnote 13 The obligation applies to ‘OTC derivatives contracts’, where the definition of derivative is that used in MiFID I,Footnote 14 and ‘OTC’ is defined as contracts which have not been executed on a ‘regulated market’.Footnote 15

Under Article 4, OTC derivatives contracts will be subject to mandatory clearing if two conditions are met. First, that type of derivative must have been declared subject to the clearing obligation and entered in a public register maintained by the European Securities and Markets Authority (ESMA).Footnote 16 EMIR provides that classes of contracts may become subject to the clearing obligation either by a ‘top down’ approach initiated by ESMA acting ‘on its own initiative’, or by a ‘bottom up’ approach, based on classes of contracts already cleared by CCPs.Footnote 17 Pursuant to the latter, on 6 August 2015, the European Commission adopted a Delegated Regulation to implement the clearing obligation as regards certain interest rate swaps.Footnote 18 This obligation will start to apply at different times, depending on the category of counterparty to the contract. These start times range from 6 months to 3 years from the entry into force of the Delegated Regulation. This is the first clearing obligation to be implemented under EMIR.

The second condition for the clearing obligation to apply is that the contracts involved must be between certain types of parties, as set out in Article 4 of EMIR. The starting point is that the obligation will apply to contracts concluded ‘between two financial counterparties’ (FCs).Footnote 19 FCs are defined in Article 2(8) of EMIR. The definition is broad and includes investment firms, credit institutions, UCITS, insurance and reinsurance undertakings, and alternative investment funds. Under Article 4, the clearing obligation will also apply to a contract where one or both parties is a ‘non-financial counterparty’ (NFC), as long as the NFC exceeds the clearing threshold.Footnote 20 NFCs are defined as undertakings established in the European Union other than CCPs and FCs.Footnote 21 As noted later in this article, this definition of FC and NFC catches a far greater range of parties than are currently members of UK CCPs.

Contracts involving NFCs will not have to be cleared unless the NFCs involved exceed the ‘clearing threshold’.Footnote 22 These thresholds have been set by the Commission, with the figures provided for each of five asset classes, including €1 billion gross notional value for credit derivatives and €3 billion gross notional value for interest rate derivatives.Footnote 23 An NFC over the individual threshold in any category (called an NFC +)Footnote 24 will have to clear all classes of derivatives (whether entered into for hedging or speculating) for as long as it is over any of the thresholds.

While the EMIR clearing obligation broadly tracks that found in Title VII of the Dodd–Frank Act,Footnote 25 there are significant differences between the two regimes. This is a source not only of political controversy,Footnote 26 but also of friction for entities having to comply with both sets of rules.Footnote 27 In the US, the mandatory clearing of standardised interest rate swaps and credit derivatives has been phased in since 2013, with the timing depending on the type of party involved in the trade.

Looking at the worldwide OTC markets, though the clearing obligation has not yet come into force in many jurisdictions, there is already significant, and growing, use of clearing. The Bank of England reports that 50 % of the global OTC interest rate derivatives market was centrally cleared in January 2015, compared to 31 % in April 2012.Footnote 28 Notwithstanding the delayed and piecemeal implementation of the G20’s agenda, therefore, CCP clearing has already become a vitally important part of the global financial market infrastructure.Footnote 29

3 The Clearing Obligation and Access to CCPs

3.1 Users of Derivatives

The clearing obligation in EMIR potentially applies to a broad range of market participants, including, as shown, not only FCs but also NFC+s. This is not just a moot point: OTC derivatives have always had a very broad range of uses and users.Footnote 30 A recent research study published by ISDAFootnote 31 demonstrates how trades involving diverse participants have become a more significant portion of market turnover in the last decade. Based on data published by the Bank for International Settlements (BIS), ISDA reports that in 2013, 65 % of the OTC derivatives markets by turnover were trades between reporting dealers (i.e., major banks and securities houses)Footnote 32 on the one hand, and ‘other financial institutions’ such as pension funds, or non-financial counterparties such as manufacturers, on the other. Accordingly, only 35 % of the market by turnover were trades where both parties were reporting dealers (and, as ISDA points out, some of this is necessary to support client trading).Footnote 33

As a result, we need to consider the types of entities which may need (or wish) to access clearing services for OTC derivatives under the new global regulatory regime, alongside the types of entities that are able or willing to become members of CCPs and thereby able to access clearing direct. Having established a potential mismatch between members and parties requiring access, the next part of the article explains how this problem is mitigated, though not solved, by structures allowing alternative ways of accessing clearing.

3.2 Membership

Article 2(14) of EMIR defines a ‘clearing member’ as ‘an undertaking which participates in a CCP and which is responsible for discharging the financial obligations arising from that participation’. This definition neatly captures the linked rights and responsibilities involved in CCP membership. Members may access clearing services and enjoy the security of facing a CCP rather than facing a market counterparty, whose counterparty risk they might have had to manage with collateral or guarantees or other third-party promises. In return, members must post margin to their CCP and contribute to a shared, pre-funded default fund. They also assume operational and administrative obligations towards running the CCP, as set out in a detailed membership agreement. For example, upon a fellow member’s default, non-defaulting members may be expected to participate in an auction of the defaulter’s positions.Footnote 34 This symbiosis helps to explain why a CCP must be so careful about selecting and monitoring its members.

The membership criteria for clearing services for OTC derivatives are onerous, even by the standards of other clearing services. This is because a CCP faces more risk clearing OTC derivatives, which have high values and long maturities compared to other cleared contracts (e.g., for commodities), while the operational complexities involved in clearing OTC derivatives are also far greater.Footnote 35 LCH.Clearnet’s published rules, for example, require that parties applying to be an individual clearing member of EquityClear have a minimum net capital of £5 million.Footnote 36 By way of comparison, an applicant to be a type of member called a futures commission merchant (FCM) Clearing Member of its SwapClear service for interest rates swaps must maintain an adjusted minimum net capital of $50 million.Footnote 37

Article 37 of EMIR, which deals with a CCP’s ‘participation requirements’ sets out, in very broad terms, the objectives which should guide CCPs when setting their membership criteria. CCPs ‘shall ensure that clearing members have sufficient financial resources and operational capacity to meet the obligations arising from participation in a CCP’.Footnote 38 Further, members must comply with entry criteria on an ‘ongoing basis’ for the duration of their membership.Footnote 39 A CCP may also impose ‘specific additional burdens’Footnote 40 on members. In practice, the resulting membership criteria are demanding financially and operationally, both at the time of applying and thereafter. Potential members must demonstrate high levels of technical capacity and satisfy numerous corporate governance requirements.Footnote 41 As discussed by Murphy, members of CCPs may also be required to participate in ‘fire drills’ where the CCP runs through its procedures for an emergency.Footnote 42 Representatives of members must take part in a CCP’s risk committee.Footnote 43 This is not to forget that membership is also expensive, not only because of the requirements to post margin and a default fund contribution, and fees, but also, as Lane, Dion and Slive point out, because of indirect costs through capital requirements. Clearing members which are banks will face increased costs under new regulatory capital rules. Specifically, they will ‘incur higher costs on their credit exposures to a CCP, on pre-funded default fund contributions and on exposures to clients who clear indirectly through them’.Footnote 44

While there is concern amongst international regulators that clearing services and other parts of the financial market infrastructure are accessible, it is notable that the new regulatory framework continues to reserve discretion over membership criteria to CCPs, as long as such measures may be related back to managing risk. Principle 18 of IOSCO’s 2012 Principles for Financial Market Infrastructures (PFMIs)Footnote 45 states: ‘An FMI should have objective, risk-based and publicly disclosed criteria for participation, which permit fair and open access.’ This is implemented in EMIR, which requires membership criteria to be ‘non-discriminatory’ and to ‘ensure fair and open access’.Footnote 46 However, EMIR is also clear in several places that this duty is subject to a CCP’s right to control its own risks by selecting members according to its own choice of criteria. For example, Article 37(1) of EMIR states that ‘[c]riteria that restrict access’ are only allowed ‘to the extent that their objective is to control risk for the CCP’.Footnote 47 Ultimately, both the PFMIs and EMIR reflect the fact that while openness is important, the safety of the CCP remains the paramount concern.

This all helps to explain the actual number and nature of clearing service members. The Bank of England, which supervises the four UK CCPs, is in the second year of publishing annual reports on financial markets infrastructures.Footnote 48 The latest shows that the four UK CCPs have memberships of 18 (CME Clearing Europe), 43 (LME Clear), 81 (ICE Clear Europe) and 98 (LCH.Clearnet’s SwapClear service).Footnote 49 A review conducted by the author of the membership lists published on each UK CCP’s websiteFootnote 50 found that there are almost no members of CCPs which are not banks and other types of financial services companies.Footnote 51 This type of membership may make for robust CCPs, but it clearly poses a challenge in a world of mandatory clearing.Footnote 52 In other words, to the extent that (1) membership of CCPs is small and still primarily made up of banks and specialist financial services companies, (2) the definition of FC in EMIR catches a broader range of market participants, such as insurers and asset managers, and (3) NFCs, such as manufacturers or energy companies, fall outside the clearing exemption and are therefore also obliged to clear, it must follow that EMIR will impose the obligation to clear on entities that are not currently members of CCPs.

Thanks to the mutual rights and responsibilities flagged up at the start of this part of the article, addressing this mismatch is not as simple as throwing open membership to any entity required to clear. In fact, mandatory clearing creates a ‘membership dilemma’, where, on the one hand, regulators require all non-exempt parties to be able to gain access to clearing, while on the other hand, CCPs must continue to be selective about their members in order to function safely, and in the way that made them so attractive to regulators in the first place. This tension between CCP autonomy and inclusiveness is the direct result of regulators having framed compulsory legislation around a private sector legal device designed to mutualise losses for selected participants. As discussed next, this membership dilemma is mitigated, though not solved, by the availability of two further options for accessing clearing.

3.3 Client Clearing

EMIR defines a client as ‘an undertaking with a contractual relationship with a clearing member of a CCP which enables that undertaking to clear its transactions with that CCP’.Footnote 53 ‘Client clearing’ therefore involves a client accessing clearing by contracting with an eligible member of a CCP.

In Europe, members of CCPs are either ‘individual members’, which may clear solely on their own behalf, or ‘general clearing members’, which may also clear for their clients. In the US, members are either clearing members, which may clear proprietary trades and trades on behalf of non-US domiciled clients, or futures commission merchants (FCMs). FCMs are required to be registered with the Commodity Futures Trade Commission and, in addition to the activities open to clearing members, they may also clear on behalf of US-domiciled clients.Footnote 54 In this article, as the focus is on the EU clearing regime, the term ‘members’, unless otherwise defined, refers to general clearing members, and the term ‘clients’ refers to entities defined as such in EMIR.

EMIR provides that clearing members may only clear for clients if they have ‘the necessary additional financial resources and operational capacity to perform this activity’.Footnote 55 In practice, client clearing is often one of a bundle of services provided by a prime broker to its client, along with secured lending and custody arrangements. As regards clearing, the prime broker/clearing member may offer related services such as collateral transformation, whereby lower-quality assets are swapped at a discount or ‘haircut’ for higher-quality ones, which are accepted by a CCP as margin. In return for these services, the member will charge fees which may be calculated in a variety of ways,Footnote 56 and may also benefit from a right of use over excess margin posted by the client but not due to the CCP, for instance, because of the effects of position netting.

In legal terms, there are two main ways that a client may structure relations with its clearing member.Footnote 57 In Europe, the ‘principal to principal’ model is the norm. In this case, the client is principal in its dealings with the member and the member is principal in its dealings with the CCP. The client and CCP have no contractual relationship, and there are separate, bilateral contracts between the member and client, and the member and CCP. The principal-to-principal model is reflected, for example, in the CCP’s fee arrangements. SwapClear’s published information for members, for example, makes it clear that all fees for clearing services will be charged to members, not clients, and then it is up to members to make individual pricing arrangements with their clients.Footnote 58

The drafting of the documentation between client and member will be complex. It must attempt to replicate the relevant membership obligations of the CCP, and, in particular, provide for the provision of margin up this intermediated chain to the CCP. The clearing member will be concerned to match up their two sets of rights and obligations, to ensure that the client is bound by the relevant membership rules of the CCP. Thus, the CCP’s requirements for clearing will have an indirect effect on the client, despite the fact that there is no privity of contract between them. To the extent that any of these obligations are not successfully matched up, the member assumes ‘asymmetry costs’,Footnote 59 for example, if a CCP demands that the member posts margin more frequently than the client has to post it to the member.

The structure used for client clearing in the US is agency-based. This means that the member deals with the CCP as agent for the client, with the result that, unlike in Europe, the client and CCP have a contract with one another. The clients’ obligations to the CCP are guaranteed by the clearing member. Given the focus on the EU, this article will proceed on the basis that the principal-to-principal model is in place.

3.4 Indirect Clearing

A third way of accessing clearing involves a market participant becoming an ‘indirect client’, defined in the EU rules as ‘the client of a client of a clearing member’.Footnote 60 Compared to client clearing, an indirect client is one step further removed from the CCP. It follows that the arguments developed about client clearing also apply to the longer contractual chain involved in indirect clearing, and many of the legal concerns will be the same in both contexts.

Indirect clearing is largely overlooked in EMIR itself, but, having been ‘introduced [into ESMA’s brief] at the last minute’,Footnote 61 it has since been addressed in Commission Delegated Legislation.Footnote 62 The Consultation Paper circulated by ESMA prior to the publication of the Commission Delegated Regulation noted respondents’ views that indirect clearing is ‘a relatively new concept and that market practices continue to evolve’.Footnote 63 This Commission Delegated Regulation, now in force, seeks to ensure that ‘any type of indirect clearing arrangements comply with minimum conditions for ensuring their safety’Footnote 64 and that indirect clients have ‘equivalent protection … as granted to clients under Regulation (EU) No 648/2012’Footnote 65 including ‘in a default scenario’.Footnote 66 For example, the Delegated Regulation extends the protections afforded by EMIR to clients, such as porting, to indirect clients.Footnote 67 It is also notable for setting out standards for each of the parties in the indirect clearing chain (apart from the end-user itself), being the CCP (Article 3), the clearing member (Article 4) and the clients (Article 5). As regards members, they are required to facilitate indirect clearing by their clients on ‘reasonable commercial terms’.Footnote 68 At the same time, the rules recognise the possibility of the membership-like burdens being imposed by members in such circumstances. Thus, the Delegated Regulation provides that terms which members impose on any clients offering indirect clearing services ‘may include minimum operational requirements’.Footnote 69

Finally, as Gregory explains, indirect clearing may also be necessary where a European bank has clients who wish to clear in the US. Under US rules, CCP members must be registered FCMs, so a European bank would have to become a client of an FCM for its own clients to access clearing.Footnote 70

3.5 Limitations of Access Arrangements

Membership of CCPs clearing OTC derivatives therefore remains onerous, but there are other ways to gain access to clearing. Given the sweeping effects of the EMIR clearing obligation, these routes are of increasing importance. There remain, however, significant concerns about how these means of accessing clearing will work in practice.

First, client and indirect access arrangements exacerbate the type of market interconnectedness that regulators intended to reduce by introducing compulsory CCP clearing. As we have seen, client clearing and indirect clearing are both based upon networks of contracts which converge on a relatively small number of financial institutions in their capacity as CCP members.

The second drawback of client and indirect clearing arrangements is that they mitigate rather than solve the membership dilemma. In other words, it remains possible that a non-exempt market participant wishing to trade a product subject to the clearing obligation may not be able to secure access to a CCP. Even though EMIR acknowledges the importance of openness, CCPs (rightly) cannot be required to take an entity on as a member.Footnote 71 Nor are members obliged to clear for any given client. Indeed, there may be good reason to refuse to clear for a particular entity. Thus, de facto exclusion from clearing is possible, though the EU regime is silent on this scenario.

The final drawback of client clearing, and the issue that is examined in detail for the remainder of this article, arises from its impact on the ‘asset-backing’ of cleared contracts. Client clearing requires assets such a securities and cash to move up and down a contractual chain, along which the assets comingle, pass through different accounts, and are likely to be rehypothecated (or lent out again) to third parties. Each step potentially creates risk for the client. This particular type of risk should be of acute concern for clients given, first, that many clients will be non-dealers new to clearing, with conservative risk profiles, and secondly, because recent events in the financial markets have demonstrated how even carefully segregated client assets may be vulnerable in times of market stress.

Client assets did not have a good crisis. Client asset rules and market-standard contracts were both found to be wanting in the case of brokers’ insolvencies, so that client assets were not returned promptly, or even subjected to an unexpected shortfall. The collapse of Lehman Brothers International (Europe) Ltd (LBIE), the London-based broker and derivatives dealer, triggered long-running and controversial litigation about paying out client money, including that which was meant to be held on a statutory trust. This culminated with the Supreme Court’s controversial decision interpreting the Financial Services Authority’s (FSA) client money rules (found in the Client Assets Sourcebook, or CASS).Footnote 72 In brief, the court held that the pool of segregated client money was to be shared even by clients whose assets had not been segregated by LBIE. Understandably, this outcome was met with great concern by the markets.

The collapse of LBIE also demonstrated the shortcomings of private arrangements for holding client assets. In an LBIE case considering a standard-form prime brokerage agreement, Briggs J (as he then was) considered the parties’ terms in detail, finding them silent on the matters in hand. After considering various possibilities in law and equity, this decision rescued the clients’ proprietary rights over cash generated from their securities by taking the unusual step of implying a contractual term in the relevant agreement.Footnote 73 The October 2011 collapse of the broker-dealer MF Global UK Ltd triggered further litigation about client assets, which once again demonstrated the uncertainties of the UK legal regime.Footnote 74 For regulators, these events helped to spark a wholesale review of CASS, which started with a consultation paper in September 2012. For market participants, this spike of litigation continues to serve as a stark warning about the potential vulnerability of client assets.

In conclusion, this part of the article has shown how the clearing obligation in EMIR (along with similar rules in other jurisdictions) creates tension between CCP autonomy and inclusiveness. A CCP’s autonomy to choose its members remains central to its risk management, while, at the same time, inclusiveness is assumed by regulatory reforms. This is one of the implications of embedding privately owned entities into mandatory public sector reforms. There are, of course, links here with debates about fair access to other financial market infrastructures, such as payment and securities settlement systems, but what this part of the article has shown is that the case of CCPs is uniquely pressing, because regulators have chosen to make clearing compulsory and because CCPs mutualise losses between their members. In this sense, the response to one lesson of the crisis (namely, the risks associated with OTC derivatives) may well be underestimating another (the risks associated with client assets). The problems which may result are considered in the final Section of the article, which examines in detail the interaction between client clearing and the posting of margin to CCPs.

4 Client Clearing and CCP Margin Arrangements

Margin is fundamental to clearing, as is reflected in EMIR’s definition of clearing as

‘… the process of establishing positions, including the calculation of net obligations, and ensuring that financial instruments, cash or both, are available to secure the exposures arising from those positions.’Footnote 75 [this author’s emphasis]

Margin provides the means by which a CCP is able to assume the risk of standing in the middle of each trade that it clears, acting as a ‘shock absorber’ for the market should a participant fail. A clearing member is required to post two types of margin to the CCP: initial margin (IM) and variation margin (VM). VM is margin collected or paid out as determined by changes to the mark-to-market value of a contract.Footnote 76 It is calculated by the CCP on a regular basis which, in the case of OTC derivatives, might be daily or even intra-day. IM is collected on the basis of a CCP’s estimation of the losses it might face due to the event of a default of a member, during the period from when the last VM has been received and the time when the contract can be liquidated.Footnote 77 A member must also contribute to the CCP’s default or ‘guaranty’ fund. The role of this fund is to mutualise losses not covered by a defaulting member’s margin. EMIR requires a default fund to be able to withstand scenarios based on ‘extreme but plausible market conditions’.Footnote 78

In the case of a default, a member’s VM and IM provide the first two lines of defence which a CCP will use to cover any losses. It is noteworthy that this has been sufficient of a buffer in many defaults in the past: Gregory reports that in the seven defaults experienced by LCH. Clearnet to date, all losses have been managed with recourse to the defaulter’s margin alone.Footnote 79 However, should further assets be needed, a CCP will work through what is referred to as the ‘default waterfall’ of resources. This is partly prescribed by Article 45 of EMIR.Footnote 80

The subject of this Section is how the collection and use of margin works in the context of client clearing. When client clearing takes place, the basic principle of a party having to back up its cleared positions with assets remains the same as described above. Accordingly, under the principal-to-principal model, the objective is that margin should be posted by the client to the member, and then by the member on to the CCP. If the client defaults, its margin should be available for the CCP to use to cover losses from positions cleared on its behalf by the member. If the member defaults, the aim under EMIR is that the client’s positions and assets should be ‘ported’, or transferred, to a new, solvent member to allow continuity for the client.

In practice, however, matters are complicated by adding the ‘client-member’ tier (and a further ‘indirect client-client’ tier, if applicable) because these arrangements raise a large number of technical legal issues. This article does not attempt to work through all of these technical legal issues, but by way of example of the complexities which may be caused by overlapping legal rules in this sector, it considers the interaction of the EMIR regime and UK national rules on client assets.Footnote 81

4.1 The Legal Regime for Client Clearing: EMIR

Given the complexity of the issues presented by client clearing, there are surprisingly few details about it in EMIR, and there is no directly related Commission delegated regulation.Footnote 82 Articles 39 (Segregation and portability) and 48 (Default procedures) are the main source of relevant rules in EMIR,Footnote 83 and, perhaps unsurprisingly given the preceding discussion, they are almost exclusively concerned with margin and the arrangements for holding it.

The central requirement of Article 39 is that CCPs make two types of accounts available to members clearing for clients, as a minimum. Under Article 39(5), a clearing member has to pass on the same choice to its clients. The first type of arrangement that CCPs are required to offer is described as ‘omnibus client segregation’ (Article 39(2)), and the second is ‘individual client segregation’ (Article 39(3)). EMIR prescribes the basic features of these accounts but gives little detail: for example, it does not specify whether the positions of clients participating in an omnibus client account should be margined on a net or gross basis.Footnote 84

In the ‘omnibus client segregation’ arrangement, EMIR requires CCPs to keep separate records and accounts to enable each clearing member to ‘distinguish in accounts with the CCP the assets and positions of that clearing member from those held for the account of its clients’. In other words, the member’s house account will be kept separate to its single, ‘omnibus’ client account. Article 39(9) goes on to explain that to ‘distinguish in accounts’ means that assets and positions are recorded in separate accounts (i.e., here a member will have a house account and a client account); that netting between different accounts is prevented; and that assets in one account may not be used to cover losses relating to positions recorded in another account.

This omnibus model has several advantages. First, the member may post net VM and IM on its net client portfolio (though, as noted above, EMIR is silent on exactly how to work this out). Because some clients’ positions are likely to cancel each other out, the member is therefore likely to hold more client margin than it is required to post to the CCP. This is an advantageous arrangement for the member, which will be able to keep this excess margin, and, if applicable, exercise its right of use powers (i.e., it may use the excess margin as collateral for its own activities). On the other hand, it is potentially problematic for clients, who may have an exposure to the clearing member for part of its margin in the event of its default.

A further disadvantage of this omnibus arrangement for clients is that there are no assets at the clearing house level which are identifiable as the individual client’s own. This means that the omnibus model represents the weaker position for the client in terms of, first, portability and, second, vulnerability to the default of other parties.

Portability refers to the option of a client moving its portfolio from one member to another member, typically in the event of a default by the original member.Footnote 85 Article 48(5) of EMIR deals with porting under the omnibus segregation model. It provides that the CCP shall

‘at least, contractually commit itself to trigger the procedures for the transfer of the assets and positions held by the defaulting clearing member for the account of its clients to another clearing member designated by all of those clients, on their request and without the consent of the defaulting clearing member.’

It is notable that under the omnibus model, all clients’ assets and positions have to move as one to a new member. Moreover, as this Article is silent on the decision-making practicalities involved in ‘all … clients’ designating a new member, or making a ‘request’ to port, this detail will be something for clients to check carefully for themselves. The second part of Article 48(5) includes the important qualification that the new member is only obliged to accept these porting clients where it has previously made a contractual commitment to do so. This is unsurprising, as it would not want to accept this burden in the heat of the moment without proper due diligence.Footnote 86 In practice, porting may be impossible anyway if the unsegregated margin has been used up because of the mutualisation of the losses of other defaulting parties. This may be the case, as Murphy shows, if the CCP closes out against the whole client portfolio, when it will have available the comingled client margin as a whole. In these circumstances, a non-defaulting client has a ‘fellow client risk’.Footnote 87

The alternative model set out in Article 39(3) of EMIR is the individual client segregation model. In this case, CCPs must offer arrangements so that members can ‘distinguish in accounts’ each client’s assets and positions from those of other clients. In practice, under this model, each client’s margin will be kept in a separate account by the CCP. This is the preferred EMIR model in terms of portability and client protection. Article 48(6) reflects this, stating that the client may, on its own, request porting, designate a new member and have its assets and positions moved. In the ordinary course of events, however, individual client segregation is less operationally convenient for the member, not least because it requires the member to post all of the margin it receives from the client. For these reasons, it will be more costly for the client.

Finally, it should be remembered that the EMIR framework sets out the minimum choice that a CCP has to offer. In practice, CCPs are marketing an array of offerings above and beyond this minimum. For example, CME Clearing Europe offers what it describes as a ‘fully segregated Client account’.Footnote 88 The clearing house states that this ‘unique form of Client account offers more collateral protection than any other account available’. The central aim behind this option seems to be that the entity posting securities as initial margin may do so while keeping them at an account with a custodian in the clearing house’s name, in other words, it avoids having to move them through a clearing member.Footnote 89 Rather than a binary choice with stark trade-offs between price and protection, therefore, CCPs’ offerings go beyond the minimum in EMIR and allow parties a choice to suit their budget and appetite for risk.Footnote 90

4.2 UK Rules: CASS

In the UK, perhaps the most significant regulatory implication of client (and indirect) clearing is that it imports a further set of legal rules into the clearing process. These are the recently reformedFootnote 91 CASS rules in the FCA’s Handbook,Footnote 92 and the interaction with EMIR is far from straightforward.

As at 2013, the FCA’s client assets regime covered 1500 firms, £10 trillion of custody assets, and £100 billion of client money.Footnote 93 It is important to note at the outset that the FCA’s CASS rules do not apply to CCPs,Footnote 94 but as the FSA explains in a December 2012 Policy Statement, they become relevant when client clearing is used because

‘[c]learing members of CCPs will often be “firms” as defined in the FSA Handbook, who hold client money for the purposes of the CASS rules. Margin transferred by a firm to a client account at a CCP may be client money from the perspective of the clearing member.’Footnote 95

These rules are designed to regulate a huge range of business activitiesFootnote 96 and they do not always sit easily with the technical and CCP-tailored EMIR regime. The fragmentary application of these rules in the clearing context is exacerbated by two further factors.

First, CASS is ‘broadly speaking, only applicable to UK firms and their EEA branches’.Footnote 97 This means that some clearing members of a UK CCP will not be subject to CASS. For instance, as the FMLC observes in its recent report, CASS will not apply ‘where a clearing member is an incoming EEA firm subject to Home State regulation of its operational arrangements under client money’.Footnote 98 Nor will CASS apply to protect UK clients using members based outside the EU, e.g., to provide UK clients with access to a third-country CCP.Footnote 99

Secondly, even if all members of a CCP were UK firms, CASS would still not apply to all of their transactions. This is because CASS only applies to transactions involving ‘client money’. So, for example, the FMLC points out that CASS does not apply to those members accepting deposits as a bank.Footnote 100 Furthermore, it does not apply to any margin provided by clients to members by way of a title transfer collateral arrangement (TTCA).

A TTCA is a popular type of financial collateral arrangementFootnote 101which a provider of collateral may choose to use as an alternative to a security financial collateral arrangement.Footnote 102 There are important legal differences between these two types of arrangements. When providing security, the client retains a property interest in the assets, though the member will usually enjoy a contractual ‘right of use’ over the assets.Footnote 103 By contrast, under a TTCA, the client retains no property rights in the assets and only has a contractual right to the return of equivalent assets. This means that whenever a TTCA is used, ‘money cannot be said to be held on behalf of that client’.Footnote 104 Therefore the protections afforded to client money and client assets in CASS will not apply if a TTCA is used.Footnote 105 This is reflected in the fact that the amended CASS rules require TTCAs to be evidenced in writing.Footnote 106

Notwithstanding this only partial overlap, EMIR significantly complicated the reform of CASS, as the latter rules had to be specially adapted to accommodate the particular legal arrangements used in client clearing. In some cases, special rules had to be written, so that CASS now includes CCP-specific provisions. The most prominent example was added to allow for clearing practices that would otherwise clash with the overarching principle in CASS 7 and 7A, namely that upon the failure of a firm, client assets should form a ‘single notional pool of client money for the beneficiaries of the general pool’.Footnote 107 Instead, clearing members are specially permitted to create separate sub-pools of client money for clients clearing through a net margined omnibus client account. The use of a sub-pool means that assets belonging to defined beneficiaries will not form part of a general pool of client assets on the insolvency of the clearing members, and that any shortfall should be confined to a particular pool and not borne by all clients.Footnote 108 Most importantly, a sub-pool should facilitate portingFootnote 109 in the event of the failure of the clearing member, by making sure enough margin is available on a client-by-client basis.Footnote 110 Indeed, the FCA states that this was the underlying objective of this change to the rules.Footnote 111 The use of sub-pools may be reassuring for clients, but, as the FCA concedes, it involves ‘operational complexities’Footnote 112 and may open the member up to litigation from clients attempting to share in sub-pools in a default.Footnote 113

In addition to these clearing-specific rules, other parts of CASS have been waived solely for clearing members. For example, there is an exemption provided for CCP members from the new rule about the ‘immediate segregation’ of client and house money. Ordinarily, the ‘immediate segregation’ rule requires firms to receive client money directly into the client bank account, rather than through the firm’s own account. This requirement would, however, be a problem for CCP members involved in client clearing, because of the interaction of EMIR with this rule. Specifically,

‘clearing members are likely to be required by CCPs to make and receive single payments that relate to both proprietary accounts and client segregated accounts at the CCP from/into a single bank account.’Footnote 114

The requirement to segregate client money immediately would therefore not work in this context. The conclusion reached by the FCA was that the final rules had to ‘make specific allowance for this scenario’.Footnote 115 As at 1 June 2015, therefore, CASS provides that firms clearing for clients will not be subject to the ‘immediate segregation’ rule if they have used ‘reasonable endeavours’Footnote 116 to arrange for the CCP to pay client and house margin separately and this is still not available. Instead, they have to meet a set of conditions, including using a house account for mixed payments, segregating client assets promptly, and maintaining in the client accounts a ‘prudent’ sum of money which will act as a buffer if something goes wrong with this substitute process and there is a shortfall.Footnote 117 Thus, EMIR has resulted in special accommodation in CASS for firms, and a lot of discretion being left to the CCP in this context. Seen alongside the other carve-outs made for CCPs and clearing members,Footnote 118 a pattern emerges which suggests that CASS not only applies in a piecemeal way, but that it is an awkward fit when it does so.

4.3 Implications

It was only to be expected that UK regime for client assets would be thoroughly overhauled after the stark problems revealed during times of market stress, including those problems which came to light in the LBIE and MF Global litigation. However, this process has been complicated by the fact that, because of client clearing, these rules apply in the CCP context, which was, simultaneously, being reformed in radical ways. The interaction between client asset rules and EMIR has impacted upon the FCA’s reforms, and resulted in multiple carve-outs and special rules solely for clearing, though significant practical and conceptual difficulties still remain. As a result, the UK client asset regime has become more fragmented and more sector-specific, for example, as regards the rules about ‘sub-pools’. In turn, carve-outs and special rules serve to exacerbate the piecemeal regime governing assets deployed for client clearing. They increase the complexity for firms required to comply with CASS, for clients and for CCPs, and, as regulators have speculated, they may intensify legal risk in the clearing sector.

How might this complexity be addressed? The particular clashes and complexities described above would, of course, be immediately addressed if firms that are clearing members of CCPs were exempted from the CASS regime for their client clearing activities. This would drastically simplify the current piecemeal rules affecting margin in the CCP context. This move would, however, remove a swathe of protections for certain clients using this UK financial market infrastructure. Given recent high-profile client asset failures, and the very recent reforms to CASS which made bespoke arrangements for firms involved in clearing, a wholesale carve-out seems very unlikely to happen in practice.

Accordingly, the best option is to look to the EU. As part of the ongoing EMIR review,Footnote 119 regulators should seek to improve the legal regime governing clearing, including by addressing the inconsistent application of, and interaction with, client asset rules. Given the heightened significance of client clearing under a mandatory clearing regime, as outlined above, this would be a highly appropriate use of the review process outlined in Article 85 of EMIR.Footnote 120 One possibility is to consider requiring CCPs to use their membership agreements to apply those client asset rules specially designed for clearing members (e.g., CASS 7.19 on clearing member client sub-pools) to all members clearing for clients, regardless of whether they are authorised firms. In this way, CCPs would be using contracts to replicate protections which are currently imposed by public sector regulation on only a portion of members and transactions. This article has identified several other issues which could usefully be addressed in the course of this review. First would be to rectify the unjustified separate treatment of client clearing (dealt with in EMIR) and indirect clearing (dealt with in Commission Delegated Legislation). Given the fundamental legal structures shared by these two types of access arrangement, they should be addressed together in the same, more comprehensive, set of rules. In any event, the EMIR review should also seek to resolve other, basic uncertainties around access to client clearing, including the uncertainties around de facto exclusion from membership and around the transparency of client and indirect clearing arrangements. But this article has argued that the overriding objective of any review of client clearing under EMIR should be to protect clients’ assets or margin in a consistent and legally certain way. This is just as important a lesson of the recent financial crisis as the risks of the OTC derivatives markets. These issues are legally complex, but now framework legislation for regulatory reform is in place in major jurisdictions, the aim should be to tackle those important questions of law which are currently unresolved or governed by piecemeal rules, while leveraging, rather than reducing, CCPs’ autonomy to govern their members and ensure safe and robust clearing services.

5 Conclusion

While the new regulatory regime for OTC derivatives depends on safely functioning CCPs, CCPs depend on selecting their own members and requiring them to post margin. As CCPs start to assume their greatly enhanced role in the OTC derivatives markets, there are many implications for lawyers to consider. This article has focused on some of them, by exploring the dilemma between CCP inclusivity and autonomy, and considering how the partial solution of client clearing generates various legal risks. It has focused on explaining certain of those risks in detail. In particular, it has analysed how the vitally important process of posting of assets for clearing purposes is complicated by arrangements allowing access in the first place.

Ultimately, the importance of the specific legal issues highlighted in this article is inversely proportionate to how inclusive CCPs are towards new members. If CCPs were to drastically lower entry and monitoring criteria, if membership became cheaper and less onerous, and if more parties were willing and able to sign up, client clearing would become less important an aspect of the clearing regime. However, such changes would be nothing short of a revolution for the CCP industry, and there are, as yet, no signs that this will happen on a significant scale. The PFMI and EMIR fall far short of calling for such changes, ultimately upholding the principle of CCP autonomy in their respective provisions about membership criteria. Assuming, therefore, that client clearing is here to stay, lawyers must do more to join economists and bankers in debating its impact and effects. Client clearing is rich in legal issues. It involves assets moving around networks of contracts between clients, indirect clients, CCPs and a small number of members. For this reason, it disrupts the neat ‘hub and spoke’ picture of CCPs preferred by many commentators, but recognising this more legally complex reality is a necessary part of implementing the G20’s objectives, and it is essential if CCPs are to safely fulfil the systemically important role which regulators have chosen to assign to them.
