SWIFT, stablecoins, and cross-border settlement

SWIFT payments connect over 11,500 financial institutions across more than 200 countries and territories. Plus, they're fast and reliable, with 89% reaching recipient banks within an hour. It's no wonder they've become the global standard for cross-border payments.

They're not flawless, however. The main point of friction shows up in the settlement layer, as global payments hop between correspondent banks. Business hours and cutoff times, foreign exchange (FX) spreads, and transaction costs can compound time and expense at every step.

Stablecoin rails offer a complementary solution to this problem. Rather than replacing SWIFT's proven instruction layer, these financial networks supplement it with a new type of programmable settlement that runs 24/7.

This guide explores the benefits of using stablecoin payment rails alongside the SWIFT network to speed up and simplify cross-border settlement.

SWIFT's role in cross-border settlement

In traditional banking, SWIFT acts as a communication system between financial institutions. Rather than transferring money, it coordinates cross-border settlement by guiding payments as they travel through intermediary banks.

What important banking functions does SWIFT support?

• Rich ISO 20022 message formatting. SWIFT messages use standard ISO 20022 to encode payment data such as remittance information and counterparty details. SWIFT has largely moved away from its older message type (MT) format, though the network still converts some legacy messages for financial institutions that haven't completed the migration to the ISO 20022 format. The richer and more structured ISO 20022 format reduces errors, improves sanctions and anti-money laundering (AML) compliance screening, and simplifies reconciliation.
• Real-time payment and fee visibility. SWIFT's global payments innovation (GPI) service tracks each payment via unique end-to-end transaction references (UETRs) embedded in every transaction. This enables users to follow payments from initiation to the moment they reach the recipient's account. GPI also itemizes the fees that correspondent banks deduct along the way for maximum transparency.
• Payment certainty. SWIFT requires receiving banks to submit confirmation updates to its GPI service every time an incoming cross-border customer payment has been credited to its beneficiary, giving senders end-to-end confirmation that the payment arrived.

24/7 tokenized-deposit payments

In recent years, SWIFT has begun to evolve past its traditional role in supporting messaging and tracking between correspondent banks. In July 2026, the network launched a pilot program for a blockchain with 17 participating financial institutions, aiming to enable 24/7 cross-border payment availability and improve liquidity efficiency.

The idea is for banks to issue tokenized deposits on their own ledgers, then use SWIFT's blockchain as an orchestration layer. This way, they don't sacrifice the compliance and control standards embedded in their current payment solutions.

How stablecoins complement SWIFT for cross-border settlement

SWIFT and stablecoin rails handle different parts of the payment flow, meaning they aren't mutually exclusive technologies. Rather, SWIFT's role is to pass payment instructions between banks, either directly if there's a correspondent banking relationship, or by routing them through intermediary financial institutions if not. Traditionally, settlement happens through the correspondent banks themselves, with each one applying debits and credits to its own ledger.

Stablecoin rails preserve SWIFT messaging by linking each payment to its ISO 20022 data as the connective tissue, while offering an alternative to settling through correspondent accounts. Importantly, banks can still use traditional payment rails, with stablecoin rails providing an additional settlement route, not a replacement.

SWIFT's blockchain takes a related but distinct approach. With stablecoin rails, the transfer itself is the settlement. SWIFT's blockchain instead orchestrates bank-issued tokenized deposits, with final settlement taking place later through established systems. Both models support always-on payments because banks don't have to wait for counterparties to open for business.

This real-world example illustrates the power of stablecoin infrastructure. Coastal Bank is a regulated sponsor bank whose fintech clients wanted a faster, cheaper option for international payments. To facilitate this, Coastal is working with Tempo to build a cross-border payment corridor underpinned by a stablecoin settlement layer. The existing know your customer (KYC)/AML framework, messaging, and banking confirmations stay the same, and the corridor is designed to give clients an efficient settlement option alongside traditional payment rails.

How can stablecoin rails improve liquidity management?

On traditional rails, financial institutions must prefund correspondent accounts outside their home jurisdiction. This is to ensure enough money is available in the right currency to cover outgoing payments. Multiply that across all the different countries and currencies they support, and a significant amount of liquidity is tied up in correspondent accounts at any given time. What's more, those parked funds are exposed to fluctuating currency exchange rates that can erode their value.

Stablecoin settlement allows financial institutions to hold more of their liquidity in a single dollar-denominated stablecoin balance and draw on it for payments in the markets their payout partners cover. Currency conversion happens at the point of payment instead of in advance, so less capital is locked up in foreign accounts, although local payout partners still need liquidity in each currency they pay out.

What programmable payment features do stablecoin rails add?

Stablecoin rails build payment logic into the transaction itself, allowing for programmable settlement. This typically includes:

• Batching: Wrapping multiple payments in a single transaction to make high-volume payouts more efficient.
• Scheduled transfers: Configuring payments to trigger at a later time, such as setting up recurring payments to suppliers.
• Conditional logic: Sending money only when a predefined condition is satisfied.
• Fee sponsorship: Covering transaction fees for another user so they can transact without having to hold a separate fee token.

These are all common features across modern stablecoin rails. The real differentiator is whether the system supports predictable, programmable execution at scale. That means stable fees and execution even at peak volume and network activity, as well as structured metadata so receiving systems can reconcile transfers more efficiently.

How Tempo slots into cross-border settlement infrastructure

Tempo is stablecoin settlement infrastructure purpose-built for payments. It sits right alongside the proven rails you already trust, including SWIFT, and acts as a complementary global payment solution, not a replacement.

Money transfers on Tempo can carry memo fields with a payment reference that links each transfer to its ISO 20022 payment data. Banks and fintechs can match incoming stablecoin transfers to the appropriate SWIFT instructions with ease, and businesses can reconcile payments against their existing enterprise resource planning (ERP), treasury, and accounting systems.

On the settlement side, dedicated payment lanes reserve blockspace at the protocol level to keep payments flowing, even when other network activity surges. Teams no longer have to plan around activity they can't control, like sudden trading spikes. Stablecoin payments on Tempo also come with predictable sub-cent transaction fees.

Companies in a range of industries are already building on Tempo, including:

• Coastal: Developing a cross-border payment system running stablecoin and traditional rails in parallel.
• Deel: Facilitating private contractor payouts to keep balances and payout history confidential.
• DoorDash: Building stablecoin-powered payment infrastructure for its global marketplace.
• ARQ: Shifting cross-border payment infrastructure to Tempo for faster settlement and lower costs.

FAQ

How do tokenized deposits and stablecoin settlement differ?

They're two different payment models. Tokenized deposits are bank deposits represented as tokens. Banks move them on blockchains, such as Tempo or SWIFT's blockchain, to allow for 24/7 payments that aren't subject to individual banks' business hours. Final settlement may happen onchain or later using traditional rails.

Stablecoin settlement uses stablecoins rather than tokenized deposits as the settlement asset. Value settles onchain at the point of transfer.

Can payment data stay private on a public settlement rail?

Yes, enterprises and financial institutions can keep certain types of payment data (such as balances and transfer amounts) hidden from public view. They can do this through a private execution environment like a Tempo Zone.

These environments connect to a public blockchain, but activities like payroll distributions that happen inside them stay private. Operators can still see all activity inside the zone, which supports their compliance and audit requirements.

Does stablecoin settlement work with ISO 20022 and existing bank messaging standards?

Yes, payments on stablecoin rails can carry references that link each transfer to ISO 20022 payment data, the same messaging standard that SWIFT and most banks already use. This means stablecoin settlement can live side-by-side with traditional banking rails. It also simplifies reconciliation by giving receiving banks clear references for matching transfers to payment records.
