Shaping the Gate: ESMA’s Draft RTS on Participation Requirements under EMIR 3

Introduction & Policy Context

On 9 October 2025, ESMA published a consultation paper proposing Regulatory Technical Standards (RTS) that flesh out the revised participation requirements under EMIR 3 (Regulation (EU) 2024/2987).

EMIR 3 amends the original EMIR regime by strengthening risk management in central clearing and improving market access. One of the key amendments is to Article 37 (Participation Requirements) of EMIR, which mandates that a central counterparty (CCP) define criteria for admitting clearing members in a way that is non-discriminatory, transparent, objective, and ensures that members have sufficient financial resources and operational capacity to meet obligations.

Under Article 37(7), ESMA is required to develop RTS to further specify the elements CCPs should consider when:

1. Establishing admission criteria.
2. Assessing the ability of non-financial counterparties (NFCs) to meet margin and default fund contributions.
   

The consultation runs until 5 January 2026, after which ESMA will collect feedback, refine the proposals, and submit final draft RTS to the European Commission.

This article offers an interpretive breakdown of the proposals, highlights technical challenges, and flags areas likely to generate stakeholder debate.

The Core Architecture: Admission Criteria for Clearing Members

Transparent, Fair & Open Access (Section 4.1)

EMIR 3 reinforces that CCPs’ admission criteria must be non-discriminatory, transparent, objective.

ESMA proposes the following as essential elements:

• CCPs should tailor criteria by product type, membership type (own vs. client clearing vs sponsored), and counterparty type (financial vs. non-financial).
• CCPs must publicly disclose their criteria, rules, procedures, and updates, in accessible formats and in commonly used financial languages.
• Where access restrictions exist, they must be justified by risk control objectives.

Stakeholder challenge: how granular should CCPs go in customizing criteria without undermining comparability or fairness?

Sufficient Financial Resources (Section 4.2)

ESMA proposes that CCPs validate a clearing member’s financial resilience in a variety of scenarios:

• Timely settlement obligations, margin calls, and default fund contributions under stressed market conditions.
• The member’s access to liquidity, credit, collateral, capital buffers and external support (e.g. from a parent group).
• The capacity to absorb losses via the default waterfall or mutualised loss mechanisms.
• Creditworthiness metrics (audited financials, ratings, CDS spreads, liabilities).
  

CCPs should also consider group support, cross-guarantees, and interdependence (financial or operational) within group structures.

A key tension: NFCs typically lack access to central bank liquidity or regulatory capital buffers—how to calibrate criteria so as not to preclude their participation by default?

Operational Capacity (Section 4.3)

Operational readiness is another gate. ESMA proposes that CCPs test:

• IT / connectivity capabilities: ability to integrate, maintain system updates, and inform CCP of changes.
• Settlement & payment system access: bank accounts, CSD accounts, backup arrangements, proven testing.
• Staff expertise and training: operational understanding of CCP rules, incident management, system failovers.
• Business continuity and operational risk controls: incident response protocols and resilience.
• Capacity for physical settlement (where relevant): in commodity markets, CCPs should assess whether clearing members can deliver goods.
• Third-party dependencies: such as reliance on outsourced services (IT, custody), and evaluation of those providers.
• Alignment with DORA (Digital Operational Resilience Act) norms for ICT resilience.
  This operational threshold becomes especially significant for newer or smaller entrants.

Other Considerations and Risk Factors (Section 4.4)

Beyond pure finance or operations, ESMA calls for additional dimensions:

• The presence of practical authorisations / licences, and prudential regulation (or equivalent) in the entity’s home jurisdiction.
• Legal enforceability of CCP claims, netting and collateral arrangements, especially for non-EU or non-regulated entities.
• Track record of compliance, sanctions, legal proceedings, group integrity, historical defaults.
• Quality of risk control frameworks and systems within the candidate.
• Sovereign and insolvency law compatibility, potential conflicts of law, and enforceability of recovery/resolution tools.
  

These “other risks” ensure that CCPs have a holistic view of membership risk.

Client-Clearing Members (Section 4.5)

Clearing members that act for clients pose additional risks. ESMA suggests that CCPs:

• Require incremental capital or operational buffers for client clearing activity.
• Assess the relative scale of client clearing in relation to the member’s own business.
• Ensure client account transparency, concentration risk monitoring, and portability of client positions on default.
• Ensure legal ability (especially cross-jurisdictional) for segregation, audit access, default handling.
  

The objective: ensure that client exposure does not overwhelm the member’s resilience or the CCP’s risk posture.

Sponsored Models (Section 4.6)

A growing access innovation is the sponsored membership model, where a “sponsor” (often a full clearing member) enables others (e.g. buy-side firms) to access the CCP through delegated infrastructure. ESMA proposes:

• Clear delineation of responsibilities between sponsor and sponsored entity, with the sponsored entity remaining financially responsible.
• Explicit prohibition of netting across sponsor and sponsored positions.
• Contingency measures (backup sponsors, fallback modes) must be vetted.
• Sponsor criteria akin to those for full clearing members.
  

This is a delicate balance: open access, but not diluting risk oversight.

Special Focus: Non-Financial Counterparties (NFCs) (Section 4.7)

EMIR 3 introduces Article 37(1a), which explicitly allows NFCs to become clearing members—but only if they can demonstrate ability to meet margin and default fund contributions, even in stressed conditions.

Further constraints: an NFC may only offer client-clearing to other NFCs within its own corporate group; and may only hold accounts or positions for itself or its group NFC clients.

ESMA’s draft RTS suggests:

• Where typical criteria (capital, licence, regulation) may not apply to NFCs, CCPs should adopt alternative safeguards (e.g. stricter collateral rules, volume limits, stress tests).
• Examples include higher overcollateralisation, product/volume caps, incremental margins, or bespoke models.
• Some NFCs may lack banking or central bank liquidity access; CCPs may require liquidity buffers or stricter collateral rules.
• CCPs must not automatically exclude NFCs purely for lacking regulatory licence, but should consider whether equivalent oversight or registration exists in their domicile.

One operational question arises: how comfortable will CCPs be accepting NFCs whose risk models or liquidity pathways are less transparent?

Implementation & Enforcement Considerations

Ongoing Assessment (Article 37(2))

Once admitted, members must continue meeting criteria; CCPs should:

• Perform annual reviews of all members’ compliance.
• Monitor significant negative developments in member risk profiles.
• Inform national competent authorities (NCAs) of material adverse developments.
  

Suspension & Exit (Article 37(4))

CCPs must include objective, transparent procedures for orderly suspension or exit of members that fall below criteria.

Denial of Access (Article 37(5))

CCPs may only deny admission to an applicant who meets criteria if justified in writing and based on a comprehensive risk analysis.

Additional Obligations (Article 37(6))

CCPs may impose extra obligations (e.g. participation in auctions of a defaulter’s positions) but only to the extent proportional to the risk posed by the member. These cannot restrict access to only certain categories.

Peer Review & NCA Reporting (Article 37(1a), etc.)

Where a CCP admits NFCs, its NCA must:

• Review arrangements periodically to ensure compliance.
• Report annually to the supervisory college on products cleared by NFCs, exposure, and risks.
• ESMA may issue opinions / recommendations following peer review.
  

Key Tensions & Stakeholder Flashpoints

1. Balancing access vs risk control
   The more robust the admission criteria, the more market participants might be excluded—particularly smaller or non-prudent actors.
2. NFC inclusion vs prudential asymmetries
   NFCs generally lack regulatory backing, banking access, capital cushions, or liquidity overtures. ESRAs will need to calibrate criteria sensibly to avoid built-in exclusion.
3. Sponsored models’ complexity
   Delegating responsibilities requires clarity: misallocation of liabilities or unclear fallback rules could create operational fragility.
4. Inter-jurisdictional enforceability
   When clearing members are non-EU entities, enforceability of CCP claims and collateral rights across legal regimes becomes a live legal risk.
5. Data burden & auditability
   CCPs must collect and verify extensive financial, operational, and structural data. The sufficiency, consistency, and comparability of that data will be critical.
6. Regulatory arbitrage and equivalence
   Should CCPs rely on host-jurisdiction equivalence or external legal opinions, the reliability of those judgments may be contested.

Practical Takeaways for CCPs, Clearing Members & Supervisors

• CCPs should begin gap analyses of their current admission frameworks against ESMA’s draft elements and identify where policies or systems must be enhanced.
• Prospective clearing members (especially NFCs or client-clearing entities) should test their financial, operational, and legal readiness against the draft criteria.
• Legal teams should evaluate enforceability of contracts, collateral arrangements, netting across jurisdictions, and insolvency implications.
• Supervisory authorities and NCAs should prepare to monitor not only access but continued compliance, and possibly assess peer-review outcomes and transparency.
• Firms and trade associations should consider responding during the consultation period (until 5 January 2026) with feedback, particularly on how the proposals interact with local market structures.
