What is a stablecoin? A stablecoin is a cryptocurrency designed to maintain a stable value relative to a chosen asset – most commonly the US dollar or euro. Unlike Bitcoin, whose price can swing by double digits within a single day, USDC and EURC always correspond to exactly 1 USD or 1 EUR. Stablecoins operate on blockchain rails, which means they can be transferred instantly, 24 hours a day, 7 days a week, without intermediary banks and without being constrained by clearing-session windows – and that is precisely why Visa and Mastercard have built a new layer of their settlement infrastructure on top of them.
Stablecoins and money transfers – in brief:
- The stablecoin market exceeded USD 300 billion in market capitalisation in 2025, with annual transaction volume above USD 27 trillion according to Boston Consulting Group
- Visa launched USDC settlement for US banks on 16 Dec 2025, reaching an annualised volume of USD 3.5 billion per month; participants include Cross River Bank and Lead Bank via the Solana blockchain
- Mastercard rolled out USDC and EURC settlement for acquirers across Eastern Europe, the Middle East and Africa (EEMEA) from August 2025
- Stablecoins settle instantly, 24/7/365 – with no session windows, no weekend pauses and no correspondent banks
- A SWIFT transfer can cost between EUR 5 and EUR 70 and take 2-5 business days; a stablecoin transfer settles in seconds for a fraction of a cent in network fees
- In the EU, stablecoins are regulated by the MiCA regulation – Circle’s USDC and EURC were the first global stablecoins to achieve MiCA compliance; USDT (Tether) remains non-compliant and has been delisted from EU platforms
- The GENIUS Act, signed in the US in July 2025, created the first federal regulatory framework for stablecoins in the United States
- Key compliance risks: AML/KYC for on-chain transactions, Travel Rule for transfers above EUR 1,000, depegging risk, regulatory fragmentation across jurisdictions
What is a stablecoin and how does it differ from cryptocurrencies like Bitcoin?
Stablecoins solve the core problem that makes Bitcoin and Ethereum unsuitable as everyday means of payment: extreme price volatility. When the value of the asset you are paying with can drop 20% before the transaction reaches the recipient, no one wants to use it for settlement.
Stablecoins eliminate that volatility through a 100% reserve-backing mechanism. USDC – the most widely used regulated dollar stablecoin – is issued by Circle: every USDC token in circulation corresponds to exactly 1 USD held in high-quality assets (cash and US Treasury bills). Circle publishes monthly reserve attestations conducted by independent audit firms. As of June 2025, USDC in circulation reached USD 61.3 billion, a 90% year-over-year increase according to Circle’s data.
The three most important differences between a stablecoin and a classic cryptocurrency:
- Value stability: 1 USDC = 1 USD always, regardless of market sentiment
- Issuer and accountability: a stablecoin has a central issuer responsible for the reserves; Bitcoin has no one accountable for its value
- Purpose: stablecoins are designed for transactions and settlement, not investment speculation
The types of stablecoins that matter for payments:
- Fiat-backed (USDC, EURC, PYUSD): fully backed by reserves in fiat currency; the highest level of safety and compliance
- Algorithmic (TerraUSD, DAI): attempt to maintain the peg through algorithms and smart contracts without full reserves; risky, with a track record of spectacular collapses (TerraUSD lost USD 40 billion in value in 2022)
For institutional payments and compliance, only the first category is relevant.
How do traditional cross-border payment methods (SWIFT, SEPA) work?
To understand what stablecoins change, you need to know how the infrastructure they aim to replace – or complement – actually works.
SWIFT (Society for Worldwide Interbank Financial Telecommunication) is an inter-bank messaging network that handles global cross-border transfers. When you send a payment to the US or Japan, your bank does not transfer funds directly – it sends a SWIFT message to a network of correspondent banks that pass the money along. Each intermediary bank can charge its own fee. According to data from European banks, the cost of a SWIFT transfer ranges from a few euros to as much as EUR 70, with a settlement time of 2-5 business days – and in extreme cases, more than ten business days if the transaction passes through multiple correspondent banks. Settlement sessions only run on business days.
SEPA (Single Euro Payments Area) is the European alternative, limited to the eurozone and selected European countries. It is faster (D+1 – next business day) and cheaper (often free or just a few euros) than SWIFT, but it operates exclusively in euro and exclusively within the SEPA area.
Common limitations of both systems:
- They only operate during business hours and business days – no settlement on weekends or public holidays
- They require intermediary banks, which extends the timeline and increases costs
- Settlement time differs from authorisation time – funds can be locked before final settlement
- For corporates: liquidity management is hampered by the unpredictability of when final settlement actually occurs
| Feature | SWIFT | SEPA | Stablecoin (USDC) |
|---|---|---|---|
| Reach | Global | Eurozone + selected countries | Global (anywhere with blockchain access) |
| Settlement time | 2-5 business days | D+1 business day | Seconds (final, 24/7) |
| Availability | Business days | Business days | 24/7/365, no breaks |
| Transfer costs | EUR 5-70 + correspondent banks | EUR 0-7 | Fractions of a cent (network fee) |
| Intermediary banks | Yes (1-5+) | No | No |
| Final settlement | T+2 to T+5 | D+1 | Instant after block confirmation |
| Currency | Multi-currency | EUR only | USD-peg (USDC), EUR-peg (EURC) |
| Transparency | Limited | Limited | Full (blockchain explorer) |
Why are Visa and Mastercard rolling out USD-denominated stablecoins for settlement?
This is the question every CFO and CISO at a financial or fintech firm should care about. The answer has nothing to do with crypto speculation – it is about settlement infrastructure.
Visa’s current settlement model works like this: when you pay with a Visa card, the transaction is authorised instantly, but the actual settlement between the card-issuing bank (issuer) and the acquirer’s bank happens with a delay, in settlement windows that operate only on business days. Banks have to maintain liquidity buffers for weekends and public holidays. Visa does not settle on Friday evening the same way it does on Wednesday morning – mismatches in schedules generate liquidity-management costs.
Stablecoin settlement changes this model. On 16 Dec 2025, Visa launched USDC settlement for US banks, offering:
- 7-day-a-week settlement – eliminating weekend windows and holiday breaks
- Instant transfer of funds on the Solana blockchain – no waiting for SWIFT sessions
- Automated treasury operations – banks can program liquidity flows via API
- Interoperability – a bridge between traditional payment rails and blockchain infrastructure
Visa reached an annualised stablecoin settlement volume of USD 3.5 billion per month by November 2025 – and that was before launching its US programme. The network runs more than 130 stablecoin-linked card programmes across more than 40 countries.
Mastercard chose a different but complementary path. In August 2025, it announced an expanded partnership with Circle, allowing acquirers in the EEMEA region (Eastern Europe, Middle East, Africa) to settle in USDC and EURC. According to the World Bank, the average cost of remittances to Sub-Saharan Africa was 8.45% of the transaction value in Q3 2024, reaching as high as 20% in some countries. Stablecoin settlement is designed to attack that cost head-on.
The strategic goal of both networks is identical: retain a central role in payments infrastructure as more financial flows migrate to blockchain – without losing the relationships with banks and regulators they have built over decades.
What benefits do stablecoin money transfers deliver?
The benefits are concrete and measurable – not marketing generalities.
For corporates and financial institutions:
- 24/7 liquidity: no more weekend or holiday “dead zones” in cash management; funds are available immediately after settlement
- Reduced cross-border costs: elimination of correspondent banks and their fees; instead of EUR 5-70 per SWIFT transfer – a network fee measured in cents
- Programmability: stablecoins can be programmed via smart contracts – conditional payment (escrow), automated distribution, splitting funds among multiple recipients in a single transaction
- Full transparency: every transaction is recorded on a public blockchain and verifiable through a blockchain explorer – real-time audit becomes feasible
- Reduced counterparty risk: in a peer-to-peer stablecoin model, payment and settlement happen simultaneously – there is no risk of funds going missing at an intermediary
For remittances:
A migrant worker sending money to family in the Philippines or Ghana today pays an average of 5-8% of the transfer value in intermediary fees. A stablecoin transfer over-the-counter or through a USDC wallet app makes it possible to send USD 500 at a cost of a few cents, with settlement in minutes – to anywhere in the world reachable by smartphone.
For emerging markets:
Access to the dollar or euro in a stable, digital form without needing an account at a Western bank. Entrepreneurs in countries with high local-currency inflation (Argentina, Nigeria, Turkey) use USDC as a store of value and a foreign-trade instrument – bypassing both inflation and capital controls.
What threats and compliance risks does stablecoin payment model carry?
This is where the work begins for CISOs, compliance directors and lawyers. Stablecoins are not free of risk – they simply carry different risks than the traditional banking system.
1. Depegging risk
The “algorithmic” stablecoin TerraUSD lost its entire value in May 2022 within 72 hours – USD 40 billion in market value wiped out. Even USDC briefly lost its peg to the dollar in March 2023 (to USD 0.87) when it emerged that Circle was holding part of its reserves at the failing Silicon Valley Bank. If a company holds operating funds in a stablecoin, depegging is a direct financial risk.
The protective mechanism: a regulated stablecoin classified as an EMT (Electronic Money Token) under MiCA must maintain 1:1 reserves in highly liquid assets. USDC undergoes monthly reserve attestations by independent auditors – that is the standard for institutional use.
2. AML and Travel Rule – new compliance obligations
Stablecoins are not anonymous – every on-chain transaction is permanently recorded and publicly accessible. But linking wallet addresses to specific individuals requires separate KYC/KYB mechanisms. The Travel Rule applies in the EU for transfers above EUR 1,000: a VASP (Virtual Asset Service Provider) must pass sender and recipient data to the next intermediary in the chain – analogous to the requirements for SWIFT transfers.
Firms accepting or sending stablecoins must address:
- Mandatory registration as a VASP or CASP (Crypto-Asset Service Provider) under MiCA
- Implementation of blockchain transaction monitoring (tools: Chainalysis, TRM Labs, Elliptic)
- KYC/KYB policies for counterparty wallets
- Suspicious transaction reporting (STR/SAR) to the FIU on the same basis as traditional payments
3. Regulatory fragmentation
The EU operates under MiCA – Circle’s USDC and EURC are compliant; USDT (Tether) has been delisted from regulated EU platforms by the end of Q1 2025 by exchanges such as Binance and Coinbase. In the US, the GENIUS Act of July 2025 established a federal framework, although detailed implementation is still in progress. In the UK, the FCA published consultations in June 2025, with final rules expected in 2026.
A firm operating globally must apply different rules in each jurisdiction. Using USDT in EU-facing operations is a MiCA breach. Using stablecoins not authorised by the FCA in the UK may become unlawful once final rules take effect.
4. Operational risk: cryptographic keys and loss of access
In a traditional bank, a forgotten password is recovered through customer service. In a crypto wallet, losing the private key = permanent loss of funds – with no recovery path. For companies holding funds in stablecoins, enterprise-grade custody is required (HSM, multisig, cold storage) along with key management policies on a level analogous to the protection of critical data.
5. USD dominance and geopolitical risk
USDC, USDT, PYUSD – the largest stablecoins are denominated in dollars. Payment infrastructure built on USD stablecoins is, in effect, an extension of dollar dominance into blockchain. For European firms: Circle can freeze USDC tokens (and does so on OFAC orders) – a central control point that does not exist in cash or in SEPA. In 2024, Circle froze thousands of wallet addresses on the request of US law enforcement.
| Risk | Category | Regulation | Required action |
|---|---|---|---|
| Stablecoin depegging | Financial risk | MiCA (EMT reserves) | Use only regulated EMTs with reserve attestations |
| Money laundering / terrorist financing | AML/CFT | AMLD6, Travel Rule, MiCA | Deploy on-chain monitoring, wallet KYC policies |
| Lack of CASP authorisation | Legal risk | MiCA, GENIUS Act | Verify whether the firm requires VASP/CASP registration |
| Loss of private keys | Operational risk | Internal policy | Enterprise custody, multisig, recovery procedures |
| Token freeze by issuer | Counterparty risk | OFAC, sanctions | Diversify; assess issuer’s freeze policy |
| MiCA non-compliance (USDT) | Compliance risk | MiCA Title IV | Immediate exit from USDT in EU-facing operations |
| Transaction taxes | Tax risk | National regulations | Consult a tax adviser; track cost basis |
How does a stablecoin differ from a traditional bank transfer and what does it mean in practice?
The most important difference is not technical – it is structural. In the traditional model, payment and settlement are two separate processes: first the bank authorises the transaction, then funds actually reach the recipient through a network of intermediaries. In the stablecoin model, payment and final settlement are one and the same action – the moment the blockchain transaction is confirmed, the funds are with the recipient. Unconditionally. Instantly.
For corporate liquidity management this means: no more reserving buffers for weekend settlement delays. No more uncertainty about when a counterparty will actually receive a transfer sent on Friday after 3 pm. No more expensive express SWIFT transfers for urgent transactions.
For the risk model this means: new categories of risk that traditional banking does not encounter – smart contract risk, blockchain risk (network outages), private key risk. These risks are real and require a different control architecture than traditional payment systems.
FAQ
Is the USDC stablecoin safe for storing corporate funds?
USDC issued by Circle is a regulated EMT (Electronic Money Token) compliant with MiCA in the EU and subject to state oversight and the upcoming federal requirements of the GENIUS Act in the US. Reserves are attested monthly by independent auditors and consist of cash and US Treasury bills. Risks remain – primarily counterparty risk to Circle as the issuer and blockchain infrastructure risk. For storing material corporate funds, enterprise-grade custody with multisig is required. USDC is not covered by deposit guarantee schemes (such as the FDIC in the US or the BFG in Poland).
How does USDC differ from USDT (Tether)?
Both are dollar-pegged stablecoins, but they differ fundamentally in regulatory status and reserve transparency. Circle’s USDC is fully MiCA-compliant in the EU, has reserves attested monthly by independent auditors and was the first global stablecoin to receive MiCA authorisation. USDT (Tether) did not obtain MiCA authorisation and was delisted from regulated EU platforms by Q1 2025 (Binance, Coinbase, Crypto.com). For firms operating in the EU: using USDT in payment operations is a compliance risk that EU-licensed banks and PSPs will not take on.
Can a company in the EU legally accept payments in USDC?
Yes, but with compliance requirements. A firm accepting or sending stablecoins may need to register as a VASP (Virtual Asset Service Provider) or CASP (Crypto-Asset Service Provider) under MiCA – depending on the scale and nature of its activity. Implemented AML/KYC policies, on-chain transaction monitoring and adherence to the Travel Rule for transfers above EUR 1,000 are mandatory. The firm should consult a compliance adviser to determine whether its business model requires a CASP licence.
How are Visa and Mastercard deploying stablecoins – do consumers pay with stablecoins?
No. Both Visa and Mastercard use stablecoins exclusively in the settlement layer between financial institutions – card-issuing banks (issuers) and acquirers. Consumers continue to pay with their cards as before. No change is required on the cardholder or merchant side. Stablecoins replace SWIFT or ACH transfers between banks during the final settlement of network obligations.
What is the risk to my business if the blockchain stops working?
Blockchain networks on which stablecoins operate (Solana, Ethereum) occasionally experience outages or congestion. Solana has had several significant outages in its history. In an institutional setting this means: stablecoin settlement should not be the sole settlement method for critical transactions. Visa maintains traditional payment rails in parallel – stablecoins are an additional option, not a replacement of existing infrastructure. Firms planning to base treasury operations on stablecoins should have fallback procedures to traditional transfers.
What is the Travel Rule and why does it apply to stablecoins?
The Travel Rule is a FATF (Financial Action Task Force) standard requiring that, for asset transfers above a threshold (EUR 1,000 in the EU), the sending institution must pass identifying data on sender and recipient to the receiving institution – analogous to the requirements for SWIFT bank transfers. In the stablecoin context: any firm classified as a VASP or CASP must implement Travel Rule mechanisms for transfers above the threshold. Technical tools (Notabene, Sygna Bridge, VerifyVASP) automate the exchange of this data between VASPs. Without Travel Rule implementation, a firm exposes itself to regulatory sanctions identical to those faced by a bank breaching AML requirements.
