Most **CASP**s in the EEA are supervised by their home **national competent authority** — Bank of **Lithuania**, **CySEC**, **BaFin**, **MFSA**, or whichever NCA granted the authorisation. A small subset cross thresholds that pull them into a different regime: **ESMA direct supervision** under [MiCA Article 84](https://eur-lex.europa.eu/eli/reg/2023/1114/oj) and **Article 85**. The threshold matters strategically because everything that scales — clients, volume, cross\-border footprint — pushes a successful **CASP** toward it, and the supervisory model changes materially when you cross.²[^1] The shift is not simply 'a different regulator'. Under **direct supervision**, **ESMA** leads a **joint supervisory team** that includes the home NCA but applies pan\-EU convergence and enforcement standards. Annual **supervisory fee**s are paid to **ESMA** on a tiered basis, on\-site inspections come from a Frankfurt\-coordinated team, and enforcement decisions are taken in Paris rather than the member\-state capital. Most **CASP**s do not want to be supervised this way; a handful of large operators are already either inside the regime or planning around its imminent application. This guide explains the significant\-**CASP** test, the criteria **ESMA** uses \(clients, value of crypto\-assets in custody, transaction volume, cross\-border footprint\), what changes when a **CASP** becomes significant, the **annual fee** structure paid to **ESMA**, who is likely already inside the regime, and how a growing **CASP** should plan for the threshold rather than be surprised by it. ## The Legal Basis — **MiCA Article 84** [Markets in Crypto\-Assets Regulation](https://eur-lex.europa.eu/eli/reg/2023/1114/oj) **Article 84** introduces the concept of a '**significant CASP**'. The article empowers the European Securities and Markets Authority to take a direct supervisory role over **CASP**s whose size, complexity, or cross\-border footprint reaches thresholds the regulator considers material to EU\-wide financial stability and investor protection.¹[^2] [MiCA Article 85](https://eur-lex.europa.eu/eli/reg/2023/1114/oj) then defines the powers **ESMA** exercises over **significant CASP**s — investigations, on\-site inspections, requests for information, and the ability to impose periodic penalty payments. The home NCA does not disappear; it remains part of a **joint supervisory team**, but **ESMA** chairs and leads. [MiCA Article 109](https://eur-lex.europa.eu/eli/reg/2023/1114/oj) maintains the **ESMA** register of authorised **CASP**s as the public list of who is authorised, who is significant, and where they are supervised.³[^3]⁴[^4] > **Warning:** Significant\-CASP designation is not a credential — it is a supervisory consequence. Operating under ESMA direct supervision means heavier reporting cadences, higher annual supervisory fees, and convergence\-driven interpretation of MiCA that may diverge from your home NCA's positions. Most CASPs work to delay crossing the threshold by structuring growth across separate regulated entities. ## The Significant\-**CASP** Criteria **MiCA Article 84** instructs **ESMA**, in cooperation with the **EBA** and the home NCA, to develop technical standards specifying the thresholds. The criteria mix quantitative metrics \(clients, value, transactions\) with qualitative factors \(cross\-border footprint, market share, systemic importance\). The published draft technical standards and the live regulatory practice converge on the following test: *Table: Significant\-CASP designation criteria — indicative thresholds and weighting \(based on MiCA Article 84 and ESMA technical standards work\).* | Criterion | Indicative threshold | Weight | Notes | | --- | --- | --- | --- | | Number of EU\-resident clients | ≥ 15 million clients | High | Coinbase, Binance EU above; smaller exchanges below | | Value of crypto\-assets in custody for EU clients | ≥ €5 billion | High | Custody\-and\-exchange combined CASPs cross first | | Aggregate transaction volume per year | ≥ €20 billion | High | Trading platforms only — pure custody firms below | | Number of EEA member states served | ≥ 5 member states with material activity | Medium | Material activity = \>5% of revenue from each | | Share of EU crypto\-asset market | ≥ 5% of EU CASP market | Medium | Recalculated annually by ESMA | | Systemic importance / interconnectedness | Qualitative | Variable | Direct ART/EMT issuer \+ CASP combination weights heavily | | Authorised since | Continuous activity for ≥ 12 months | Threshold filter | Excludes newly\-authorised firms | > **Note:** ESMA looks at the totality of criteria. A CASP that hits any single quantitative threshold is reviewed; a CASP that hits two or more is presumptively significant. The first formal designations are expected in the second half of 2025 with effect from 1 January 2027. Operators already above thresholds should be planning supervisory engagement now, not reacting to a notice in 2026. ## What Actually Changes Under Direct Supervision Direct supervision shifts the operating model in five tangible ways. The first is structural: **ESMA** leads, the home NCA participates. The next four are operational: reporting cadence, inspections, enforcement, and fees. *Table: Operating\-model changes when a CASP becomes significant.* | Dimension | Under home NCA | Under ESMA direct supervision | | --- | --- | --- | | Lead supervisor | Home NCA \(e.g. Bank of Lithuania, CySEC\) | ESMA Paris, with home NCA on the joint supervisory team | | Reporting frequency | Quarterly \+ ad\-hoc | Monthly \+ standing data feeds \+ ad\-hoc | | On\-site inspections | 1–2 per year, NCA\-led | 2–4 per year, ESMA\-led with NCA participation | | AML supervisor | Home NCA \+ national FIU | ESMA \+ home NCA \+ AMLA \(post\-2027\) | | Enforcement decisions | NCA, in member\-state language | ESMA, in English; appeals via EU courts | | Annual supervisory fees | NCA scale \(typically €10k–€60k\) | ESMA tiered — see fee schedule below | | Convergence pressure | Member\-state interpretive variations possible | Single ESMA interpretation applies | | Public visibility | ESMA register lists authorisation | ESMA register flags significant\-CASP status; supervisory letters published when issued | ## **ESMA** Supervisory Fees for Significant **CASP**s **ESMA** recovers the cost of **direct supervision** through annual **supervisory fee**s levied on each **significant CASP**. The fee structure has two layers: a **fixed fee** covering general supervisory overhead, and a **variable fee** proportional to revenue. The combination is materially higher than the **supervisory fee**s a **CASP** pays to its home NCA — a direct cost of crossing the threshold. - Fixed fee: €100,000–€350,000 per year depending on size band, covering general supervision, **joint**\-team coordination and pan\-EU coordination work. - Variable fee: approximately 0.5% of **CASP** revenue subject to **ESMA**\-issued caps, recalibrated annually. - Special\-supervision fee: charged at cost recovery for specific inspections or investigations beyond standard supervision. - Application / re\-designation fee: one\-off €25,000–€75,000 on first significant designation and on material change of activity. ## Who Is Likely Already Inside the Regime **ESMA**'s first significant\-**CASP** designations are expected to apply to **CASP**s that already exceed thresholds at the date of their **MiCA** authorisation. Public information and reasonable inference suggest the following operators are above one or more thresholds and are likely candidates. - **Coinbase** Europe — multi\-million EU clients, Class 3 custody \+ trading, authorised in **Ireland**. - **Kraken** — large EU client base, multi\-jurisdiction **Ireland**/**Malta** footprint, custody and trading. - **Binance** entities \(BAM Trading Services, **Binance** Europe\) — depending on final structure, plausibly significant on multiple criteria. - **Bitstamp** \(Robinhood subsidiary\) — large EU footprint with Luxembourg / Slovenia base. - Tier\-1 EU\-native exchanges \(Bitpanda, BitcoinSuisse equivalents\) — plausibly above the 15\-million\-client and 5\-member\-state tests within 12–24 months of **MiCA** authorisation. - Significant **ART** issuers \(Circle EURC, **MiCA**\-authorised Tether euro counterpart\) — separate **Article 84** regime applies to **ART**/**EMT** issuers, often overlapping with significant\-**CASP** analysis where the issuer also operates a trading venue. ## Planning for the Threshold If your **CASP** is growing toward but below thresholds, three planning moves are common. - Activity segmentation. Hold custody, trading, and advisory in separate authorised entities so no single legal person crosses the value\-of\-assets\-in\-custody or transaction\-volume threshold prematurely. - Geographic segmentation. Limit material activity to fewer than **five member states** until the operating model is mature, then expand. - Engagement strategy. Open a confidential dialogue with **ESMA**'s [Crypto\-Assets Standing Committee](https://www.esma.europa.eu/) 12\+ months before crossing — significant\-**CASP** designation handled cooperatively is materially better than designation imposed.⁵[^5] These are tactical, not strategic. The right strategic posture for a serious **CASP** is to assume that scaling to a meaningful EU presence eventually pulls you into **ESMA direct supervision**, and to design the regulatory and operational stack to be inspection\-ready under **ESMA** convergence standards from day one. ## Common Pitfalls Around the Threshold - Underestimating the reporting burden. Monthly data feeds \+ standing supervisory dashboards demand engineering investment that does not exist for most NCA\-supervised **CASP**s. - Treating the home NCA as the only relationship. Even pre\-significance, **ESMA**'s **Crypto\-Assets Standing Committee** influences NCA positions; not having that channel matters when designation arrives. - Misreading the criteria. Number of clients includes inactive accounts under most readings; client value is gross AUC not net; transaction volume is principal\-amount notional, not net. - Failing to budget for the fee. €100,000–€350,000 fixed plus **0.5% of revenue** is a material P&L hit for a mid\-margin **CASP**. - Missing the [AMLR](https://eur-lex.europa.eu/eli/reg/2024/1624/oj) / **AMLA** overlay. From **10 July 2027**, **AMLA** also directly supervises \~40 **highest**\-risk obliged entities; **significant CASP**s are likely candidates for both **ESMA** and **AMLA** dual oversight.⁷[^6] ## Frequently Asked Questions ### When does **ESMA direct supervision** actually start? First designations are expected in the second half of 2025 with effective application from **1 January 2027**. Designation is not retrospective — operators above the thresholds today operate under home\-NCA supervision until **ESMA** formally designates them. The technical standards underpinning the threshold are at advanced consultation stage and finalisation is expected during 2026. ### If I run two regulated entities, do they aggregate for the test? **ESMA** looks at group activity, not legal\-entity activity. A holding structure with two operating **CASP** subsidiaries does not avoid the threshold — group\-level metrics \(consolidated EU clients, aggregate AUC, aggregate transaction volume\) drive the assessment. Activity segmentation can delay designation if used genuinely \(separate businesses, separate management\); it does not avoid it permanently for a single coherent operator. ### Can I appeal a significant\-**CASP** designation? Yes — the designation is an **ESMA** decision subject to administrative appeal to the **ESMA** Board of Appeal and onward to the EU Court of Justice. Appeals are rare in practice; most operators that cross the threshold prefer to engage cooperatively with **ESMA** early rather than litigate the designation. The cost\-benefit on appeal is generally negative — fee differential vs litigation cost. ### Does **direct supervision** give me a better passport? No — every authorised **CASP** already passports across all 30 EEA member states regardless of supervisor. **ESMA direct supervision** is operationally heavier, not commercially better. The benefit of a **Coinbase** or **Kraken** presence in Europe is brand and regulatory credibility for institutional counterparties, not enhanced **passporting** rights. ### How is supervision split between the home NCA and **ESMA** in practice? **ESMA** chairs the **joint supervisory team**, sets the supervisory plan, and leads on\-site inspections. The home NCA retains operational knowledge of the supervised entity, contributes day\-to\-day monitoring, and handles language\-specific items. Disagreements between the NCA and **ESMA** are resolved by **ESMA** in last instance, with appeal rights if material. The relationship is functional rather than adversarial in practice. ### Will my **AML** supervisor change if I become significant? Possibly. **AML** supervision under [EBA Guidelines](https://www.eba.europa.eu/) and **AMLR** is partly distinct from **MiCA** prudential supervision. Significant **CASP**s that also meet **AMLA**'s selection criteria \(cross\-border **AML** risk, scale of obliged\-entity activity\) will fall under **AMLA** **direct supervision** in addition to **ESMA** — **AMLA** operational from 2026, **direct supervision** from 2028. Plan for the dual\-supervisor scenario rather than assuming one supervisor covers both.⁶[^7] > **Call to action:** Approaching significant\-CASP thresholds?
