New Rails: Stablecoin Redefining Cross-Border Payments for Corporate Treasury

A tokenised settlement infrastructure represents the most significant shift in cross-border payments since the introduction of Swift. Mark Sutton, Senior Manager, Zanders, and Thomas Otendal, CFO, Ubyx Inc., examine the new landscape.

Cross-border payments remain one of the last great friction points in global finance. Despite decades of incremental improvement, corporate treasurers at the world's largest companies still contend with settlement delays measured in days, opaque fee structures, and an architecture that separates messaging from settlement in ways that create cost, risk, and operational complexity.

This is not a new observation. The G20 made enhancing cross-border payments a priority in 2020^[1], and every major industry body has published recommendations since. What is new is that a credible alternative infrastructure now exists; not in theory, but in production. Stablecoin-based settlement rails, underpinned by DLT and institutional-grade custody, are moving from proof of concept to live deployment.

With the current correspondent banking model creating persistent friction, how can a stablecoin settlement infrastructure address each pain point, and what does this means for corporate treasury teams preparing for the next generation of payment rails?   

Persistent friction at scale

The architecture of cross-border payments has remained fundamentally unchanged for decades. When a corporate treasurer in London needs to pay a supplier in Singapore, the payment traverses a chain of correspondent banks, each maintaining bilateral relationships, each potentially applying fees, each adding processing time.

This model creates four categories of friction that corporate treasury teams manage daily:

1. Cost accumulation: Each bank in the cross-border chain can apply fees, including intermediary and beneficiary banks. For multinationals managing thousands of payments monthly, these costs compound into millions annually.
2. Settlement latency: Swift GPI^[2] improved visibility through payment tracking, but tracking a slow payment does not make it faster. Cross-border payments routinely take 24 to 48 hours to reach the beneficiary.
3. Principal integrity: Intermediary banks frequently deduct fees from the payment itself. The supplier receives less than invoiced, triggering reconciliation queries and damaged supplier relationships.
4. Settlement risk: CLS^[3] Bank covers only 18 currencies, leaving large swathes of global trade exposed to overnight and multiday settlement risk in the correspondent banking model.

These are not edge cases. They are structural features of the correspondent banking model, experienced daily by every corporate treasury function operating internationally.

It is worth emphasising that this is not a criticism of the banks and institutions that operate within the correspondent banking framework. These institutions have invested heavily in modernisation; the Swift MT to MX migration^[4], GPI tracking, pre-validation services. These investments have delivered genuine improvements. The point is structural. The separation of messaging from settlement, the reliance on chains of bilateral banking relationships, and the batch-processing cadence of traditional payment systems create inherent limitations that no amount of incremental optimisation can fully resolve.

A new architecture

Stablecoin-based payment infrastructure does not incrementally improve the correspondent banking model. It replaces the underlying architecture with one designed for the requirements of modern treasury operations.

Atomic settlement: The transfer of value and its confirmation occur in a single, indivisible operation. Settlement finality is measured in seconds, not days. Settlement risk is eliminated entirely.

Continuous operations: 24 hours a day, 365 days a year. No cut-off times, no batch-processing windows, no weekend closures. Genuine real-time liquidity management across every time zone.

Transparent costs: Visible, predictable fee structures with no hidden intermediary charges. The sender knows the cost upfront; the beneficiary receives the full amount.

Programmability: Smart contracts enable conditional payments, automated sweeps, threshold-triggered distributions and rules-based treasury operations as native capabilities. Programmability transforms payment operations from a sequence of manual instructions into an automated, rules-based system. The implications for cash management, working capital optimisation, and SCF are substantial.

Institutional infrastructure ready

A common objection, particularly from risk-conscious treasury functions, has been that stablecoin infrastructure lacks the institutional controls required for corporate use. This objection was valid two years ago. It is no longer accurate.

Regulated instruments: MiCA^[5] in Europe and emerging frameworks in the US, Singapore and the UAE have created regulatory clarity for stablecoin issuance, reserve management and redemption. Corporate treasurers can now evaluate stablecoins within established regulatory frameworks rather than operating in a legal grey area.

Institutional custody: Qualified custodians now offer segregated custody, insurance coverage, and the maker-checker controls that corporate treasury functions require. The custody infrastructure for digital assets has converged with the operational standards of traditional securities custody.

Settlement venues: Institutional-grade settlement venues provide the compliance, onboarding, and operational frameworks that connect regulated financial institutions with stablecoin infrastructure. These are not experimental platforms, they are production environments designed for institutional throughput.

Network diversity: Corporate treasurers are not limited to a single blockchain network or a single type of digital money. The toolkit now spans regulated stablecoins, tokenised bank deposits, and tokenised MMFs. These provide the diversification across risk, yield, and liquidity dimensions that prudent treasury management requires.

Benefits across the board

The practical implications for corporate treasury teams are significant and near-term:

• Working capital release
  Reducing settlement times from days to seconds releases trapped liquidity across the payment cycle. For a multinational with billions in transit, even a one-day reduction can release hundreds of millions in working capital.
• Operational simplification
  Programmable payments reduce manual intervention for conditional payments, multicurrency sweeps and intercompany settlements. They are more automated, more auditable, and less error-prone.
• Risk reduction
  Atomic settlement eliminates counterparty exposure inherent in multiday settlement windows. Capital currently reserved against settlement risk can be redeployed.
• Cost reduction
  Fewer intermediaries, transparent fee structures and automated processing reduce the total cost of cross-border payment operations.
• New capabilities
  These include automated liquidity rebalancing, conditional supply chain payments, and real-time cash concentration across entities and jurisdictions. These strategies are simply not possible on current rails.

Transition has begun

Global cross-border payment flows are projected to grow from $190tr. in 2023 to $290tr. by 2030^[6]. The infrastructure that processes these flows will determine the cost, speed, and risk profile of international commerce for the next decade.

The correspondent banking model served global trade well for half a century. But the structural separation of messaging from settlement, the reliance on chains of bilateral relationships, and the batch-processing architecture of legacy systems create friction that incremental improvement cannot fully resolve.

Stablecoin settlement infrastructure offers a genuine architectural alternative; one that delivers atomic settlement, continuous operations, cost transparency, and programmability. The regulatory frameworks are in place. The institutional infrastructure is ready. The instruments exist.

For corporate treasury teams, the question is no longer whether stablecoin-based settlement will play a role in cross-border payments. It is how quickly to develop the internal capabilities, governance frameworks, and banking relationships needed to access these new rails.

The transition has begun. The treasurers and institutions that engage now will shape the standards. Those that wait will adopt them.

The way ahead

The first step for treasurers is to identify use cases based on high-friction corridors (for example, cross-border payments to emerging markets or intercompany funding) where traditional payment rails struggle. This process will highlight both the business need and potential urgency around experimentation.

The next step is to engage in more detailed conversations with possible partners and vendors to determine any key dependencies, critical actions, and potential timelines. This detailed analysis will help treasury take the transformational step from being a passive observer to an active participant in the new, real-time digital financial landscape.
