Issuing an Asset-Referenced Token (ART) Under MiCA Title III: Authorisation, Reserve, and Own Funds

The EMT is the easy stablecoin. A single fiat currency, a one-to-one reserve, and an authorisation regime that leans on the existing e-money framework. The asset-referenced token — an ART — is the opposite. It references a basket of currencies, one or more commodities, or one or more crypto-assets, and for that it sits under the heaviest authorisation regime in the Markets in Crypto-Assets Regulation.¹^[1]

Issuing an ART means prior authorisation from a national competent authority, a ring-fenced reserve of assets, a standing own-funds requirement, an approved crypto-asset white paper, and — above defined thresholds — a significant-ART escalation that transfers supervision directly to the EBA. None of these layers is optional.

This guide maps the full ART Authorisation Stack — five layers, in the order a real issuance project encounters them — and sets it against the lighter EMT regime so you can see exactly where the extra cost, capital, and supervisory weight lands.

MiCA splits crypto-assets into three buckets: asset-referenced tokens, e-money tokens, and all other crypto-assets. The ART carries the most onerous obligations because it can reference anything other than a single official currency — and that exposes holders to market, currency, and concentration risk that a single-currency EMT does not.

The consequence is structural. An ART issuer must be authorised before it issues — there is no notification-only route. It must hold a reserve of assets that is legally segregated, custodied by third parties, and reconciled daily. It must carry own funds on top of the reserve. And it must publish an approved white paper — not merely a notified one.

The verdict up front: an ART is roughly twice the regulatory project of an EMT, and the moment it scales past the significance thresholds in Article 43, the EBA takes over as direct supervisor and the own-funds floor steps up.

The dividing line is the reference asset. An EMT references the value of one official currency — a euro stablecoin, a dollar stablecoin. An ART references anything else that gives it a stable value: a basket of currencies, gold or another commodity, one or more crypto-assets, or a mix of those.

That single classification choice drives everything downstream. EMT issuance leans on the EMD2 e-money framework and a notified white paper. ART issuance requires a standalone Title III authorisation, a more demanding reserve regime, and a white paper the NCA must positively approve.

Treat an ART issuance as a five-layer stack. Each layer has its own legal basis, its own deliverables, and its own failure modes. Skip one and the authorisation does not complete.

1. 1

   Authorisation Application — the Article 18 application pack and the credit-institution exemption decision.

2. 2

   Reserve of Assets — the Article 36–38 segregation, custody, investment, and reconciliation regime.

3. 3

   Own Funds — the Article 35 capital requirement sitting on top of the reserve.

4. 4

   Crypto-Asset White Paper — the Annex II content set, subject to NCA approval, not just notification.

5. 5

   Significant-ART Escalation — the Article 43–45 thresholds, EBA direct supervision, and enhanced own funds.

Under Article 16, an ART may only be offered to the public or admitted to trading in the EU by a legal person authorised by its NCA or by an authorised credit institution. The application itself is governed by Article 18, and the technical standards set the form and content of the pack.²^[2]

There is a key fork. A credit institution already authorised under EU banking law does not need a fresh ART authorisation — but it must still notify its NCA, draw up an approved white paper, and comply with the reserve and own-funds regime. Everyone else needs the full Article 18 authorisation.

The application pack must include, among other items:

• A programme of operations and the proposed governance arrangements.

• The crypto-asset white paper and the legal opinion that the token is not an EMT or a MiFID II financial instrument.

• The reserve-of-assets policy, custody arrangements, and the redemption policy.

• Proof of own funds, a fit-and-proper assessment of management, and the identity of qualifying shareholders.

The NCA assesses completeness, then has a defined review window to grant or refuse. In parallel it consults the EBA and ESMA, and where the issuer touches monetary policy, the ECB or the relevant central bank. A negative ECB opinion on monetary-policy grounds can be decisive.

The reserve of assets is the prudential heart of the regime. Under Article 36, the issuer must constitute and maintain a reserve of assets that fully backs the ART, is legally and operationally segregated from the issuer's own estate, and is insulated from the issuer's creditors in insolvency.

Segregation is not a bookkeeping convention. The reserve must be ring-fenced so that, on issuer failure, holders have a priority claim over reserve assets ahead of general creditors. That requires the right legal structure, the right custody contracts, and a daily proof that the reserve equals the value of tokens in circulation.

Custody is governed by Article 37. Reserve assets must be held by qualified third-party custodians — a credit institution for cash, an authorised crypto custodian for any crypto component, and an appropriate custodian for commodities. Custody must be segregated, and the issuer remains liable to holders for any loss attributable to a custodian.

Investment of the reserve is constrained by Article 38. Where the reserve is invested, it may only go into highly liquid financial instruments with minimal market, credit, and concentration risk, per the EBA's investment and liquidity RTS. Investments must be capable of liquidation at minimal price impact, and any gains or losses sit with the issuer, not the holders.³^[3]

Daily reconciliation is the operating discipline that holds the regime together. The issuer must prove, every business day, that the market value of reserve assets at least equals the value of the ART in circulation, and top up any shortfall from own funds. A reserve that drifts below par is a supervisory event.

Own funds sit on top of the reserve, never inside it. Under Article 35, an ART issuer must hold own funds equal to the highest of three measures.

• A fixed floor of €350,000.

• 2% of the average amount of the reserve of assets.

• A quarter of the prior year's fixed overheads.

The mechanics of the 2% reserve measure mean own funds scale with the token. A reserve of €500 million implies own funds of €10 million — far above the fixed floor. The EBA's own-funds RTS sets out exactly which instruments qualify and how the average is computed.⁴^[4]

An NCA can also require own funds up to 20% higher where its risk assessment warrants it, or lower by up to 20% for lower-risk tokens. Plan for the higher end of the band when modelling capital.

The ART white paper is not a marketing document. Its mandatory content is fixed by Annex II, and — unlike most crypto-assets, which are merely notified — the ART white paper must be approved by the NCA as part of authorisation.⁵^[5]

Annex II demands, among other things:

• A full description of the reference assets and the stabilisation mechanism.

• The reserve-of-assets and custody arrangements, and the rights of holders.

• The redemption rights and procedure, including conditions and fees.

• A prominent risk-warning set covering market, currency, custody, and concentration risk.

The white paper also carries civil liability. If it is incomplete, unfair, or misleading, holders who suffer loss can claim against the issuer — so the document is drafted by counsel, not by marketing, and every reserve and redemption representation must match the operating reality.

Once an ART scales, Article 43 can reclassify it as a significant ART. The EBA's significance framework measures holder base, transaction value and number, reserve size, interconnectedness with the financial system, and activity across borders.⁶^[6]

Indicative thresholds include a holder base above 10 million, a reserve value above €5 billion, or daily transactions above 2.5 million / €500 million. Meeting at least three of the criteria is the trigger the EBA weighs.

The consequences are material. On a significant-ART designation, supervision transfers from the NCA to the EBA directly. Own funds step up from 2% to 3% of the reserve under Article 45, and the issuer faces enhanced liquidity, interoperability, and remuneration-policy obligations.

The fastest way to see where the extra weight lands is to set the two token types side by side across the dimensions that drive cost and time.

The second comparison shows what changes when an ART crosses the Article 43 significance line.

On paper the reserve is one pool. In practice it is a custody split across asset classes, each with its own custodian type, its own reconciliation feed, and its own liquidation playbook.

• Cash and deposits — held at one or more credit institutions, spread to manage concentration and counterparty risk.

• High-quality liquid instruments — the Art. 38 eligible book, sized to the redemption-liquidity profile, capable of same-day liquidation.

• Commodity or crypto components — where the peg includes them, held by an appropriately authorised custodian and marked daily.

The bank-side architecture is where ART issuance most often stalls. You need segregated reserve accounts, a custodian willing to provide the insolvency-remote structure MiCA requires, and operational rails that let you mint and redeem at par without commingling. Securing that architecture is a banking and structuring problem before it is a regulatory one.

The reserve-banking layer mirrors the EMT case in shape, so the stablecoin issuer banking architecture framework transfers directly — with the difference that an ART reserve must accommodate multiple asset classes, not a single currency.

Two contingency documents are mandatory. Under Article 46, every ART issuer must maintain a recovery plan setting out the measures it would take to restore compliance where the reserve or own funds fall short, per the EBA's recovery-plan guidelines.⁷^[7]

Under Article 47, the issuer must also hold a redemption plan — an orderly wind-down that returns the reserve to holders at par if the issuer ceases to operate. The plan must be capable of execution without contagion, and it is reviewed by the NCA or, for significant ARTs, the EBA.

The redemption right itself, under Article 39, is permanent: holders can demand redemption at any time, at market value of the referenced assets, and the issuer must honour it. That redemption promise is what the entire reserve, own-funds, and recovery stack exists to protect.

An asset-referenced token (ART) is a crypto-asset that aims to keep a stable value by referencing any value or right other than a single official currency — typically a basket of currencies, one or more commodities such as gold, one or more crypto-assets, or a combination. Under MiCA Title III, it can only be issued by an authorised issuer holding a backing reserve.

An EMT references one single official currency and leans on the e-money framework, with a notified white paper. An ART references anything else and requires a standalone NCA authorisation, a more demanding reserve regime, and an approved white paper. The ART is the heavier of the two regimes.

Own funds must equal the highest of three figures: a fixed €350,000 floor, 2% of the average reserve of assets, or a quarter of fixed overheads — and the NCA can require up to 20% more. At scale the 2% measure dominates, so a large reserve implies own funds in the millions, separate from and on top of the reserve itself.

An ART becomes a significant ART when it meets at least three of the Article 43 criteria — broadly a holder base above 10 million, a reserve above €5 billion, high transaction volume, cross-border activity, or financial-system interconnectedness. On designation, the EBA supervises directly and own funds rise to 3% of the reserve.

• Stablecoin Issuer Banking Architecture: how to structure segregated, insolvency-remote reserve accounts on the bank side.

• MiCA Compliance Guide for CASPs: the full authorisation walkthrough for EEA crypto-asset service providers.

• EBA Significance Designation Pipeline: how Articles 43 and 56 reclassify tokens into direct EBA supervision.

The ART is the most demanding token MiCA contemplates, and that is by design — a token that references a basket, a commodity, or a crypto-asset carries risks a single-currency stablecoin does not. The issuers who succeed will be the ones who treat the reserve, own funds, and white paper as one engineered system from day one, and who build the significant-ART uplift into the plan before the EBA ever has to ask. Build the stack to survive scale, and authorisation becomes a milestone rather than a ceiling.
