The familiar complaint runs like this: a cross-border payment leaves on a Thursday afternoon and the beneficiary sees it on Monday, after intermediary banks, an FX conversion at a rate nobody quoted in advance, and a cut-off that quietly moved the value date. That is the problem stablecoins are pitched against. Some of it is genuinely fixed. Some of it is moved to a different counterparty, still there, just less visible. The useful question for a treasurer is which frictions go, which stay, and which simply change owner. None of what follows is tax, legal, accounting or investment advice.
Settlement time and cut-offs
Correspondent banking runs on business days, time zones and cut-off times set by each bank in the chain. A public blockchain does not close for the weekend. Visa's announcement of 16 December 2025, launching USDC settlement in the United States, put it this way: with USDC settlement, issuers get “seven-day availability and enhanced operational resilience across weekends and holidays.” The first banks named were Cross River Bank and Lead Bank, settling with Visa in USDC over Solana, with broader US availability planned through 2026. On 3 June 2026 Mastercard expanded its own settlement support to USDC, PYUSD, USDG, USDP, RLUSD and SoFiUSD across eight blockchain networks, describing “intraday, weekend, and holiday settlement for issuers and acquirers” while, in its words, preserving existing fraud safeguards and dispute processes.
Two caveats belong next to that. Both announcements concern settlement between the card networks and the banks that issue and acquire on them, not a company paying its own suppliers, so the benefit to a corporate treasury is indirect until a bank or payments provider passes the faster cycle on. And what counts as final settlement differs from one blockchain to another; a company relying on it needs to know how finality works on the specific chain its provider uses, rather than assume it behaves like a wire.
What can reach a company's own payables and receivables directly is the absence of a weekend. Where both sides hold stablecoin balances through a provider, a payment due on a Friday need not wait for Monday because a bank is shut; it can move whenever the provider's systems are running. That is a change to working-capital timing, separate from the network settlement Visa and Mastercard describe.
FX conversion does not disappear, it moves
Each stablecoin is tied to a single currency, and the market is overwhelmingly denominated in dollars, a gap covered in our look at non-dollar stablecoins. A treasurer paying a supplier who invoices in another currency still needs a conversion somewhere in the chain. It now happens at whichever regulated entity takes fiat in or pays it out, or inside an orchestration layer on top. The spread and the counterparty change. The need for a rate does not.
That matters for reconciliation as much as for cost. A bank FX conversion arrives on a statement with a rate and a value date the treasury system already knows how to book. A conversion done inside a provider's ledger may not produce the same record unless the provider is asked for it, which is a question to settle before signing rather than at the first quarter close.
Who stands between the company and the chain
Very few corporate treasuries touch a blockchain directly. A regulated intermediary sits in between, running the customer checks, holding the licences and converting at each end. Bridge, the stablecoin infrastructure company whose acquisition Stripe completed on 4 February 2025, describes its own product in exactly those terms: customers can “receive, convert, send, and withdraw on the same platform,” with “Stripe's compliance expertise” and a “unified KYC process” behind it. That is vendor material about its own service, but it shows the usual shape of live corporate use: not a company holding a wallet itself, but a licensed provider doing so on its behalf, with the fiat conversion, the compliance checks and the banking relationships still in place underneath.
Issuer risk: who can freeze a balance
Our earlier piece on stablecoins from the institutional side covers reserves and attestations. The risk specific to payments is different: an issuer can freeze a balance, and issuers do.
Two 2026 episodes show the range. On 23 April Tether announced that it had frozen more than $344 million in USDT across two addresses, in coordination with OFAC and US law enforcement; CoinDesk later reported those funds as linked to the Central Bank of Iran. On 16 July, after OFAC added four wallets linked to the same central bank to its sanctions list, CoinDesk reported that Tether had frozen a further $131 million, taking the total blocked across both actions to roughly $475 million. The other episode involved no sanctions designation. On 23 March Circle froze 16 unrelated business hot wallets, including exchanges, online casinos, forex platforms and payment processors, in connection with a sealed civil lawsuit in a New York court, and unfroze one of them on 26 March. At a press conference in Seoul on 13 April, Circle's chief executive, Jeremy Allaire, said the company is able to freeze a wallet “at the direction of law enforcement or the courts.”
The operational point for a treasurer is that a working balance can be immobilised by a legal process the company is not party to and may not hear about in advance. That failure mode is worth reflecting in how much working capital sits in a stablecoin balance at any one time.
Accounting: a proposal, not a rule
US accounting for stablecoins as cash equivalents is not settled. On 15 April 2026 the FASB tentatively decided to add illustrative examples on when a digital asset can be a cash equivalent, stressing that the threshold remains high. On 18 August 2026 it issued a proposed Accounting Standards Update, with comments due by 19 November 2026. As Deloitte summarises the proposal, a stablecoin would need three things: a right for the holder to redeem it for cash from the issuer on demand without significant fees; that right held directly with the issuer, not through an intermediary; and issuer reserves that are sufficient, high-quality, liquid and segregated, covering at least the value of every token in circulation. Holding a stablecoin through an exchange, however easy to sell, would not meet the direct-redemption test. It is a proposal, not a finished standard, and until it is final a company's auditors decide how a stablecoin balance is presented, not a vendor's marketing page.
Sanctions screening and the travel rule
The freezes above happen after a transfer. The preventive layer is screening by the providers involved and the travel rule, which requires originator and beneficiary information to pass between the sending and receiving providers. Its implementation still differs by jurisdiction, as set out in our piece on travel rule compliance in practice. A company paying counterparties in several countries through a stablecoin provider will find that what each provider asks for depends on where that provider, and the one on the other side, is regulated.
Where the rules stand
- United States: the GENIUS Act is law, but its core licensing requirement has not yet begun to apply. According to the US Treasury, from 18 January 2027, the Act's expected effective date, a person generally may not issue a payment stablecoin in the United States without a federal or state licence, and from 18 July 2028 digital asset service providers generally may not offer or sell payment stablecoins to persons in the United States unless a licensed issuer issued them. On 17 August 2026 Treasury issued a proposed rule implementing section 3 of the Act, open for comment for 60 days from its publication in the Federal Register.
- European Union: MiCA's rules for e-money tokens have applied since 30 June 2024. Only credit institutions and e-money institutions may issue them, and holders have a claim to redeem at par value at any time. Some of the European Banking Authority's technical standards on issuers' reserves and liquidity have been adopted; its page still lists the standard specifying highly liquid financial instruments in the reserve as a final draft.
- Global standards: the Financial Stability Board published its high-level recommendations for global stablecoin arrangements on 17 July 2023. Its review of 16 October 2025 found implementation “incomplete, uneven and inconsistent,” and said few jurisdictions had finalised their frameworks for global stablecoins.
Outside the EU, then, a treasurer paying in stablecoins today is largely working ahead of finished rules.
What is evidenced, and what is only claimed
A corporate announcement is not an operating reality, and neither is an industry estimate.
The Visa and Mastercard announcements are dated corporate actions, and both concern network settlement rather than direct corporate payments. Western Union announced USDPT, a dollar stablecoin issued by Anchorage Digital Bank on Solana, on 28 October 2025, saying it expected to launch in the first half of 2026. Anchorage announced the launch on 4 May 2026, naming three uses: Western Union's internal treasury settlement across corridors, liquidity for partners on its Digital Asset Network, and a consumer product, Stable by Western Union, due in June 2026 in Mexico, Argentina, Colombia and the Philippines. Of the three, the treasury use is the one a corporate reader should watch, because it is a large payments company moving its own money this way.
Volume claims deserve more caution. The Defiant reports that a report by the analytics firm Artemis and Stablecon found business-to-business stablecoin payments grew more than 730% year on year in 2025, and estimated total annual stablecoin payments at $390 billion. That is an estimate derived from on-chain data by private firms, not an audited or officially reported figure, and the methodology is not set out in the article. Read it as a claimed order of magnitude, not a reconciled number.
What the programme covered
Two sessions on the June 2026 programme in Paris addressed this question. “Stablecoins and the New Economics of Global Payments” was a side event hosted by Morph on 2 June; the agenda named no individual speakers for it. “The Current State of Global Stablecoin Rails: Payments, Settlement and Compliance” was a panel on 3 June, moderated by Eddie Chong, with Christian Niedermüller, Josiah Senu and Suzanne Morsfield on the panel. Where software-initiated payments enter the picture, the authorisation and liability questions set out in our piece on agentic commerce remain separate and unresolved.
The decision a treasurer faces is a trade-off: settlement that does not stop for weekends, against an issuer that can freeze a balance, an accounting answer that is still a proposal, and compliance requirements that change with each counterparty's jurisdiction.
