⁹ International standards for the regulation of CCPs exist but fall short of generating uniformity among national regimes and facilitating international trade flows. The recognition of third countries’ regimes is key to attaining market access to foreign jurisditions.

¹⁶ EMIR, Art. 25 (2) (b).

¹⁷ EMIR, Art. 25 (2) (a). Additionally, the actual wording is of significance, see EMIR Art. 25(6): The Commission may adopt an implementing act under Article 5 Regulation (EU) No. 182/2011, determining that the legal and supervisory arrangements of a third country ensure that CCPs authorized in that third country comply with legally binding requirements which are equivalent to the requirements laid down in Title IV of this Regulation, that those CCPs are subject to effective supervision and enforcement in that third country on an ongoing basis and that the legal framework of that third country provides for an effective equivalent system for the recognition of CCPs authorized under third-country legal regimes. It is deduced from that provision that the Commission's assessment of third-countries’ regulatory frameworks is threefold.

⁴⁸ On several occasions the parties to derivatives contracts are not members of clearinghouses. Thus, these parties need to acquire the services of other institutions, which are members, to ensure access to the clearinghouse's services. This scenario perplexes our theory and it is intentionally disregarded. See Turing, D., Clearing and Settlement (London: Bloomsbury, 2016), pp. 44–49Google Scholar.

⁵¹ GATS Article XXVIII(m)(i) lays out that ‘juridical persons of another Member’ shall be constituted or organized according to the law of that other Member.

⁵² For the EU Schedule, see www.wto.org/english/tratop_e/serv_e/serv_commitments_e.htm. However, it should be mentioned that the EU consists of 28 Members, for the time being, and not all Members’ commitments are reflected in the EU schedule, notified to the WTO. Some EU Members schedules are still in force independently. For the sake of completeness, it shall be mentioned that Estonia and Latvia have undertaken Mode 1 commitments for clearing services in their schedules GATS/SC/127 and GATS/SC/126, respectively. The analysis, however, does not delve into particular market access and national treatment commitments on clearing services undertaken by EU Members, but rather captures the greater picture in light of the adoption of the Understanding.

⁵³ The Understanding is not of binding nature and therefore it is up to WTO Members to undertake their financial services commitments in accordance with the principles promulgated by it. The Members that have voluntarily adhered to it are the following: Australia, Bulgaria, Canada, Czech Republic, European Communities (EC15), Hungary, Iceland, Japan, Lichtenstein, New Zealand, Nigeria, Norway, Slovak Republic, Sri Lanka (excluding insurance), Switzerland, Turkey, and the United States.

⁵⁴ See WTO, supra note 50, p. 10.

⁵⁵ In respect of Mode 1, the Understanding mandates that a Member shall allow non-resident suppliers of financial services to provide, ‘as a principal, through an intermediary or as an intermediary, and under terms and conditions that accord national treatment’, a specific number of services: (a) insurance of risks relating to maritime shipping and commercial aviation and space launching and freight, (b) reinsurance and retrocession and the services auxiliary to insurance, (c) provision and transfer of financial information and financial data processing as referred to in subparagraph 5(a)(xv) of the Annex and advisory and other auxiliary services, excluding intermediation, relating to banking and other financial services as referred to in subparagraph 5(a)(xvi) of the Annex. When it comes to what appears to be Mode 2, the commitments have quite a broader scope; Members ‘shall permit its residents to purchase in the territory of any other Member the financial services indicated’ in the previous paragraph, and additionally all banking and other financial services listed in subparagraphs 5(a)(v) to (xvi) of the Annex. Consequently, the obligations emanating from the coverage of Mode 1 are narrower than of Mode 2.

⁷⁸ ESMA's technical advice are objective-based analyses which examine the non-European countries’ regimes on a line-by-line basis, resulting in a thorough but cumbersome process, that can be verified by the fact that the Dodd-Frank framework got the green light from the Commission only in 2016. See, for example, the ESMA technical advise issued for the US: www.esma.europa.eu/sites/default/files/library/2015/11/2013-1157_technical_advice_on_third_country_regulatory_equivalence_under_emir_us.pdf.

⁸⁰ From GATT jurisprudence, the panel in China–Raw Materials noted that the lack of definition, guidelines, or standards in how the export quotas were allocated by local departments constituted non-uniform administration inconsistent with Article X:3(a). Panel Report, China – Measures Related to the Exportation of Various Raw Materials, WT/DS394, paras. 7.751–7.752.

⁸¹ The watering-down of the excessive regulatory scrutiny in equivalence determinations and the focus solely on the regulatory provisions that matter can facilitate the international integration of clearing services. This approach is consonant with efficiency considerations of increasing liquidity and reducing transaction costs in the derivatives clearing business. The International Swaps and Derivatives Association (ISDA) put forward five principles according to which equivalence/subsituted compliance frameworks should operate in order to avoid the current troublesome state-of-play, see ISDA, ‘White Paper: Cross-Border Harmonization of Derivatives Regulatory Regimes’ (September 2017).

⁸² See GATS Article VI:4.Article VI:5 has been defined as ‘an effort to operationalize the objectives stated in VI:4, the most important of which was the necessity test’, according to the WTO Secretariat in WTO, WPDR, ‘Report on the Meeting Held on 11 May 2001’, S/WPDR/M/11, 7 June 2001, para. 29.

⁸³ The GATS entered into force in 1995 and this category captures the measures in place before then.

⁸⁴ Panel Report, Mexico–Telecoms, para. 5.30.

⁸⁵ The Implementing Acts are based on Article 5 of Regulation No. 182/2011 and are highly dependent upon the technical advice on third countries regimes that ESMA produces. The Commission Delegated Regulation (EU) No 153/2013 of 19 December 2012 supplementing EMIR with regard to regulatory technical standards on requirements for central counterparties, on the basis of art. 2 sets out particular conditions in respect of CCP's target member states, types of instruments cleared, its shareholders, margin and collateral, stress tests, compliance, record, outsourcing arrangements, segregation arrangements, membership criteria, and interoperability arrangements. Although numerous criteria are put forward, it is maintained that there is no transparency on the methodology that these criteria are assessed by the EU institutions.

⁸⁶ This presumption is based on Article 3:8 of the Dispute Settlement Understanding (DSU) which has been confirmed by the WTO judiciary.

The concept of nullification or impairment also accommodates non-violation complaints in services, GATS Article XXIII:3.
