The route considered here uses an Irish electronic money institution (EMI), a separately authorised Irish conversion provider and euro accounts at an Irish credit institution. Irish safeguarding and insolvency provisions determine the issuer-side analysis. Moving an account, issuer or conversion provider to another EEA state requires that state's rules to be checked.
Executive Summary
- Keep customer tokens, conversion proceeds, card balances, company collateral and earned fees separately identifiable. Company money applied to issue customer e-money changes category; it cannot also remain an undrawn corporate reserve. (Irish Electronic Money Regulations 2011, reg. 29(1)–(2); Regulation (EU) 2023/1114 (MiCA), art. 70.)
- Prefer security over a company-owned bank-account claim, with effective issuer control and restricted drawings, where the issuer and scheme accept it. A title-transfer arrangement requires a separate decision on issuer credit risk. (Irish Financial Collateral Arrangements Regulations 2010, regs. 2–4.)
- Clear the Mexican treasury and customer-service roles separately. European authorisation does not answer Mexican restrictions on accounts, token services or foreign customer flows. (Ley para Regular las Instituciones de Tecnología Financiera (LRITF), arts. 22, 30 and 45–47; Banxico Circular 4/2019, provision 3.)
- Allocate conversion losses and settlement credit before enabling spend. Refund, redemption and safeguarding duties remain with the responsible regulated entity despite reimbursement disputes. (Irish Electronic Money Regulations 2011, regs. 28–29 and 52–55; European Union (Payment Services) Regulations 2018, regs. 17 and 95–98.)
The issuer needs available fiat when settlement falls due
Stablecoin receipt, sale execution, fiat receipt and card settlement are separate events. The funding documents should identify which event makes money available for settlement. A token transfer or an executable quote does not establish that the issuer has collected euros.
The issuer's scheme obligation also remains separate from its claim against the programme company. For a Visa programme, the public rules require issuer payment of valid card transactions. Prepaid rules additionally address reserves and issuer control of programme funds, subject to specified exceptions. A company-name collateral account therefore needs scheme-compatible control and issuer acceptance. The scheme rules are contractual requirements; they do not establish a statutory prefunding percentage. (Visa Core Rules and Visa Product and Service Rules, 24 October 2026, rules 1.7.6.1 and 4.13.1.2.)
The recommended product credits spendable fiat value only after conversion proceeds are final and available. If the commercial model allows earlier spending, the issuer and company must document who finances the gap, its limit and repayment source. Any credit granted by the Irish EMI must satisfy the applicable ancillary-credit conditions, including restrictions on using payment-service users' funds. A repayable corporate reserve should not be described as the issuer's regulatory capital. (Irish Electronic Money Regulations 2011, regs. 13–16 and 28(3), as amended.)
The operating schedule should distinguish an authorisation hold from a captured transaction and a settled liability. Offline transactions, late presentments and adjustments can survive a decision to stop new authorisations. The agreed reserve must address those exposures using the selected scheme's actual timelines and the programme's transaction data.
Ownership changes when the money changes purpose
The balance map should identify the account holder, the person entitled to the asset, the corresponding debtor and each permitted movement. An account label or group brand cannot answer those questions.
Customer tokens held by a custodian remain subject to the customer's recorded rights and MiCA's custody protections. The custodian must separate customer holdings from its own and protect them against its creditors in accordance with applicable law. Customer tokens cannot be treated as the programme's settlement collateral. (MiCA, arts. 70(1) and 75(2), (6)–(7).)
Conversion creates a further distinction. A completed sale to a principal converter can leave the customer with an unpaid price claim until payment occurs. Money actually received and held for the customer requires the applicable client-fund protection. For a crypto-asset service provider (CASP) that is not itself a bank, payment institution or EMI, MiCA requires client funds other than e-money tokens (EMTs) to enter an identifiable separate bank or central-bank account by the end of the following business day. For those excluded institutions, the applicable banking, payment-services or e-money regime must be assessed. (MiCA, art. 70(2)–(5).)
Where the card product creates e-money, the customer holds a claim against the Irish issuer. Funds received in exchange for that value must be safeguarded. Under the segregation method, they must not be mixed with others' money; the statutory bank-placement deadline does not grant permission to use them as working capital. If the product instead holds payment-account money, the payment safeguarding rules apply. (Directive 2009/110/EC, art. 2(2); Irish Electronic Money Regulations 2011, reg. 29(1)–(3); Irish Payment Services Regulations 2018, reg. 17, as amended by S.I. No. 169/2025, reg. 4.)
Corporate funding can also become customer backing. If the company pays the issuer to credit customer e-money, the corresponding amount enters the safeguarding analysis. The same amount cannot simultaneously count as customer backing and remain freely recoverable company collateral. Keep the reserve outside the customer's spendable balance and document any draw that changes its use.
The recommended reserve is a separate company-owned claim against the account bank, subject to agreed security. It issues no customer spending entitlement. Earned fees belong in operating accounts only after the contractual entitlement arises and the allocation is reconciled. Refunds and unsettled conversion proceeds must not be relabelled as fees.
Use Mexican law and the actual Mexican bank terms for the source treasury account. For the selected Irish route, specify Irish law, the account bank's Irish office and separate mandates for the CASP's client-fiat account, issuer safeguarding account, settlement account and corporate collateral account. Record the governing law of the token and custody contracts separately. A governing-law clause does not by itself settle proprietary priority or foreign insolvency effects. (Ley General de Títulos y Operaciones de Crédito, arts. 267–268; Irish Financial Collateral Arrangements Regulations 2010, regs. 2–3.)
Each entity needs permission for its actual role
The Mexican treasury role must remain distinct from customer services
The Mexican company should buy euros through an authorised provider and post its own corporate resources within its objects and approved powers. That act alone does not make it an operator of customer payment accounts or a money transmitter receiving funds for a remitter. Receiving customer money, promising redemption or controlling conversion requires a separate perimeter decision. (Ley General de Sociedades Mercantiles, arts. 4 and 10; Ley General de Organizaciones y Actividades Auxiliares del Crédito, arts. 81 and 81-A Bis; LRITF, art. 22.)
An institution of electronic payment funds (IFPE) has additional restrictions. Its client resources require segregation, and foreign-account customer flows depend on the statutory CNBV authorisation arrangements. Banxico's virtual-asset regime permits authorised internal operations while excluding direct customer exchange, transmission and custody from that authorisation. Outsourcing cannot expand the Mexican institution's permitted activities. (LRITF, arts. 45–47; Banxico Circular 4/2019, provisions 2–3 and 11.)
Classify the selected stablecoin under Mexican law before enabling Mexican distribution. LRITF's virtual-asset definition excludes assets denominated in legal tender or foreign currency. A value reference alone does not establish legal denomination. The authorities have also warned that fiat-funded, fiat-denominated issuer claims can involve reserved deposit-taking. A MiCA classification cannot resolve that Mexican question. (LRITF, art. 30; Banxico, SHCP and CNBV joint statement, 28 June 2021, pp. 2–3.)
Where the Mexican virtual-asset AML regime applies, operating a conversion platform can trigger duties without custody. The statute expressly includes qualifying operations with Mexican citizens from another jurisdiction. Registration does not authorise reserved financial services. The parties must identify the responsible local and foreign providers before onboarding; implementation must also account for the rules generally commencing on 30 November 2026. (Ley Federal para la Prevención e Identificación de Operaciones con Recursos de Procedencia Ilícita (LFPIORPI), arts. 17(XVI) and 18; SHCP Acuerdo 115/2026, First Transitory.)
The Irish issuer and converter need separate service assessments
The issuer needs authority for the proposed e-money and card-payment functions. A converter providing custody, exchange or transfers needs the corresponding MiCA permission. An EMI's notification route for custody and transfers of its own EMTs does not confer general permission to exchange another issuer's token. Check each legal entity's authorisation and cross-border scope. (Irish Electronic Money Regulations 2011, regs. 6 and 28; MiCA, arts. 59–60 and 65.)
A single-currency stablecoin meeting MiCA's definition is an e-money token. Its lawful EU offering must satisfy the relevant issuer and white-paper requirements. For new EU customer activity, select a compliant token: ESMA's 8 October 2026 opinion expects CASPs to stop services involving non-compliant stablecoins, including custody and transfers. Its limited arrangements for existing holdings concern supervised wind-down, not launching new business. (MiCA, arts. 3(1)(7) and 48; ESMA Opinion ESMA75-113276571-1742, paras. 7, 12–14 and 21–27, supervisory opinion.)
Payment permission needs a separate check. The EBA distinguishes exchange itself from relevant EMT transfer and wallet services. Its February 2026 opinion also addresses first-party transfers and restricted continuation for pending applicants. That continuation does not provide a route to onboard this new programme's customers. Require the relevant payment authorisation or a legally constituted arrangement with an authorised payment provider. The provider must actually perform the regulated service within that arrangement. (MiCA, art. 70(4); EBA/Op/2025/08, paras. 21, 23 and 27–28; EBA/OP/2026/01, paras. 8–15, supervisory opinions.)
As at 29 October 2026, the original MiCA service-provider transition has ended. The EBA's supervisory treatment of EMT safeguarding also does not relax ordinary fiat safeguarding. The issuer must make the applicable notifications for changes to its business or safeguarding arrangements. Businesses considering their own institution can assess the required scope through payment and e-money licensing. (MiCA, art. 143(3); EBA/Op/2025/08, paras. 21 and 48; Irish Electronic Money Regulations 2011, regs. 18 and 31.)
Security and set-off must preserve the correct claims
Irish safeguarding protects the prescribed customer-fund category against issuer creditors and insolvency officeholders until holders' proper claims are satisfied. It does not give an unrelated corporate reserve that priority. Safeguarding accounts should carry explicit restrictions on unrelated liens, account combination, set-off and sweeping, supported by the bank's signed acknowledgment. (Irish Electronic Money Regulations 2011, reg. 29(4); Irish Payment Services Regulations 2018, reg. 17(3), as amended.)
For corporate collateral, negotiate a closed set of secured programme obligations. The preferred agreement preserves the company's bank-account entitlement, prohibits reuse and permits drawings only against evidenced liabilities. The bank should acknowledge the issuer's control and exclude competing rights for unrelated debts. Effective control, eligible parties and written evidence must satisfy the financial-collateral rules before their enforcement protections can be relied upon. (Irish Financial Collateral Arrangements Regulations 2010, regs. 2–4 and 6–7, as amended.)
If the issuer requires title transfer, price that alternative explicitly. The company transfers entitlement and depends on contractual rights to equivalent collateral or surplus. A separate ledger in the issuer's name does not recreate the company's original bank claim. Obtain a credit limit, reporting rights and defined return terms before accepting that exposure. (Irish Financial Collateral Arrangements Regulations 2010, regs. 2 and 11.)
Private contracts cannot promise release despite a statutory freeze. The Central Bank can direct restrictions on EMI account payments, and financial-collateral protections preserve applicable resolution restrictions. The documents need procedures for legally blocked accounts and replacement liquidity. (Irish Electronic Money Regulations 2011, reg. 60(4); Irish Financial Collateral Arrangements Regulations 2010, reg. 3(8), as substituted by S.I. No. 547/2022, reg. 14.)
Issuer failure should trigger reconciliation, customer redemption or transfer arrangements, and a separate calculation of corporate surplus. Programme failure should stop new uncovered exposure while preserving funding for existing obligations. Mexican insolvency rules can affect stays, netting and avoidance, including increased security not contemplated when the original obligation arose. Agree the security and margin formula at inception, then obtain Mexican and Irish advice on the actual enforcement route. (Ley de Concursos Mercantiles, arts. 65, 90, 105 and 112–115.)
Conversion failure requires a different response. Decline new spending unless an approved party funds the shortfall. After a valid fiat obligation has arisen, a depeg or converter default must be allocated under the funding agreement without taking unrelated customers' assets. Bank failure needs its own contingency: separation from the issuer's estate does not eliminate exposure to the deposit bank.
The funding agreement must make every draw and release testable
The programme company, issuer, converter and banks should settle these terms before the first customer funding:
- Define the euro reserve from unsettled card obligations, evidenced refund and chargeback exposure, and a justified liquidity buffer. Exclude unavailable conversion proceeds and avoid counting the same exposure twice.
- Specify valuation times, price sources, permitted token and currency conversions, fees, slippage limits and banking cut-offs. Allocate losses between quote acceptance and final euro receipt.
- Set margin triggers, notice channels, payment deadlines, dispute handling and the point at which new authorisations stop. Derive amounts and deadlines from the actual settlement timetable and exposure data.
- Restrict drawings to defined liabilities, require supporting records and prevent double recovery. Maintain separate customer, scheme, conversion and collateral reconciliations.
- Allocate refunds, chargebacks and redemption separately. A merchant refund or scheme chargeback is not the same as a statutory unauthorised-payment refund. Where the latter rule applies, refund is due immediately and at latest by the business day following awareness or notification, subject to the specified fraud exception and liability rules. Programme reimbursement disputes must not delay those duties. (Irish Payment Services Regulations 2018, regs. 95–101 and 112.)
- Preserve the customer's applicable fiat e-money redemption right. The EMT holder's separate redemption claim is against the token issuer; it does not promise immediate euro proceeds from a third-party converter. Specify the refund currency and any new conversion instruction. (Irish Electronic Money Regulations 2011, regs. 52–56; MiCA, art. 49.)
- Set the remaining reserve by identified liabilities on termination, with review dates, reductions and final release criteria. Provide ledger exports and replacement-provider cooperation, subject to required permissions and legal restrictions.
The company should transfer the reserve only after corporate authority, source of funds, bank acceptance and the security documents are confirmed. Customer activity should begin only after the issuer and converter have the necessary permissions, the Mexican distribution route is cleared, and reconciliation and failure procedures operate as agreed. These are separate conditions: funding an account does not authorise the product.
