The Bank of England’s latest test with stablecoins and a digital pound isn’t just a sandbox experiment. It’s laying the legal and technical blueprint for a monetary system where central bank liabilities and private commercial bank money become fully interoperable code.
The central bank has now entered Phase 2 of its digital pound exploration, focusing intensely on cross-border trade finance. According to an announcement reported by CoinDesk, its Digital Pound Lab is specifically testing whether public stablecoin infrastructure and central bank digital currency (CBDC) can coexist in a single, automated payment flow.
The targeted beneficiary is clear: smaller businesses choked by slow, manual trade finance. Otto Jacobsson, U.K. chapter lead at the Digital Assets Association, noted that delays in the current system make it harder for these firms to prove creditworthiness. “If these processes can become faster and more efficient, U.K. businesses could unlock working capital sooner and make it easier to finance international trade,” he told CoinDesk.
This work follows the broader pattern of central banks scrambling to define their place in a world of digital assets, a topic we touched on in our analysis of Banks Revolt Against Regulator's Crypto 'Live Surveillance'.
Here’s what the BOE has built so far and what it’s setting out to solve.
How did the Bank of England's test even work?
The experiment is a specific use case known as invoice factoring. Here’s a step-by-step breakdown of the proposed new architecture:
The Setup: The BOE’s Digital Pound Lab is working with partners NOBO Finance, Dun & Bradstreet, and Polygon Labs. It’s a “no real customers or money” simulation running on the Hyperledger Besu enterprise blockchain. The goal is to prove automation and interoperability concepts, not move real funds.
The Problem: Today, an exporter might wait days or weeks for payment after shipping goods. That’s "frozen capital" for a small business.
The New Flow:
- The Digital Handshake: The partnership builds a “bankable profile” for an SME by combining wallet transaction data, open-finance info, and Dun & Bradstreet’s business intelligence. This creates a reusable, portable credit identity.
- The Instant Advance: Once goods ship (proven by an electronic bill of lading), a smart contract automatically triggers. The exporter receives an advance payment immediately. This payment is not in pounds. Notably, the exporter receives it via stablecoin technology.
- The Final Settlement: The U.K.-based importer makes the final payment. This settlement, however, happens not in stablecoins but in the central bank's own experimental money: a potential digital pound.
“For digital money to actually move the world’s trade, its different forms have to work together, public and private, central bank money and stablecoins,” said Marc Boiron, CEO of Polygon Labs. “This experiment tests exactly that.”
This two-step settlement, stablecoin for the exporter abroad, digital pound for the importer at home, is the core innovation. It’s a practical stress test of a hybrid system. This aligns with a growing industry focus on payment rails, as seen in efforts like Thredd Backs Stablecoin Card Spans Hong Kong, Mexico.
Why is getting stablecoins and digital pounds to work together so difficult?
It’s not a technology demo. The real challenge is interoperability between two fundamentally different forms of money with distinct issuers, legal frameworks, and risk profiles.
Technical Bridging: A stablecoin and a CBDC are likely to exist on different ledgers or platforms with different technical protocols. The BOE lab is testing how to make an atomic swap or conditional payment that seamlessly links these systems. Polygon Labs is providing what it calls an "Open Money Stack" to handle the stablecoin side, including fiat-to-stablecoin conversion, wallets, and smart contracts. The other side is the central bank's CBDC ledger. Getting them to communicate with perfect finality is a non-trivial engineering problem.
Legal & Regulatory Bridging: More complex than the code is the governance. If a payment fails in this hybrid chain, who is liable? The stablecoin issuer? The central bank? The smart contract developer? Defining this is part of the experiment's mission. The BOE is simultaneously building a regulatory framework for this future. Sources indicate the BOE’s separate policy statement on systemic stablecoins, released in June 2026, lays out explicit rules, including a 70/30 backing ratio (70% in government debt, 30% in BOE deposits) and, critically, interoperability requirements mandating that sterling stablecoins be built to connect with a future digital pound.
What changes for a small business if this becomes real?
The promise is dramatic, but the implications are layered.
The Direct Benefits:
- Speed: Settlement could shift from days to minutes, tied to verifiable events like a digital bill of lading.
- Working Capital: Exporters get paid upon shipping, not upon complex bank clearance. This unlocks frozen capital.
- Access: A portable, verifiable digital credit identity could make it easier for SMEs to prove their creditworthiness to financiers anywhere.
The New Risks & Uncertainties:
- Liability in Code: The allure of a "self-executing" smart contract is also a risk. If goods are disputed but the code has already released payment, which legal system untangles it?
- Credit Redefinition: If transaction history on a digital ledger becomes the primary source for credit scoring, it could advantage digitally-native firms while penalizing cash-based businesses.
- Systemic Complexity: Linking multiple private stablecoin systems to a central bank’s core infrastructure increases the digital attack surface and potential points of failure. The stability of the system depends on its weakest technical or regulatory link.
What questions must be answered before this hybrid system goes live?
The Digital Pound Lab’s design phase runs through mid-2026. Before any real-world launch, the BOE and U.K. Treasury must confront unresolved questions that this test only begins to surface.
Privacy vs. Transparency: A central bank ledger for a wholesale CBDC would have unprecedented visibility into inter-company payment flows. What data does the BOE see, and under what authority? How is commercial confidentiality protected? This is a live debate in finance, as legacy banks also chafe under new surveillance proposals.
The Role of Traditional Banks: In this test flow, if importers settle directly with the central bank using a digital pound and exporters get paid via a non-bank stablecoin, where does that leave commercial banks? Are they reduced to credit providers and identity verifiers, or do they retain a core role in payment orchestration? The lab’s partnership with data firm Dun & Bradstreet suggests identity and data may become the new battleground for financial relevance.
Scalability and Global Adoption: The test is a controlled, bilateral scenario. Could this architecture handle the volume and complexity of global trade? Furthermore, it requires other jurisdictions to adopt compatible digital money systems for the exporter’s stablecoin receipt to be useful. True transformation requires global standard-setting, an effort far beyond a single lab.
The findings from this Phase 2 experiment will feed into the BOE and Treasury’s joint assessment of the digital pound ahead of their next decision later this year. The watch item isn't just whether the technology works, but whether the Bank of England can design a system where control is shared, interoperability is mandated by law, and private innovation is channeled rather than stifled. They aren't just testing a payment flow. They are testing a new philosophy of money.
