Bank of England lab tests digital pound and stablecoin in one trade flow

A Bank of England pilot puts sterling at the final settlement leg of a cross-border trade flow dominated by dollar stablecoins.

A long corridor in a data center is lined with dark server racks displaying glowing blue and green indicator lights, leading to a glass-partitioned office space with desks and computers, brightly lit by overhead ceiling panels.

The Bank of England has selected a three-party consortium, comprising UK fintech NOBO Finance, data intelligence firm Dun & Bradstreet, and blockchain infrastructure company Polygon Labs, to advance into Phase 2 of its Digital Pound Lab. The experiment places sterling at the settlement layer of a live-format cross-border trade flow, with an exporter receiving payment via a stablecoin rail while the UK importer settles in digital pounds. The test uses no real money or customers, but its architecture carries real strategic weight.

The context is acute. Last week the IMF warned that local-currency stablecoins in emerging markets risk accelerating dollarisation rather than resisting it, because liquidity and user behaviour already gravitate towards dollar-denominated tokens. The same structural logic applies to any non-dollar currency. With almost every stablecoin in circulation pegged to the dollar, payment systems migrating onto blockchain rails risk marginalising sterling as a settlement currency by default, not by design.

Sterling in the stack

The Digital Pound Lab is the Bank of England's controlled environment for testing whether central bank digital currency and private stablecoins can interoperate rather than compete. Phase 2 extends NOBO's Phase 1 work on conditional B2B escrow payments into a fuller stack. Two workstreams are being developed in parallel.

The first is an SME Bankable Profile: a reusable, consent-driven credit identity that combines wallet transaction signals with Dun & Bradstreet's commercial risk data and Polygon's smart contract infrastructure. The objective is a portable financial identity that small businesses own and can present to any lender, replacing the manual verification rounds that currently freeze capital between shipment and payment.

The second is an electronic bill of lading-backed invoice factoring flow with multi-rail settlement. Polygon's Open Money Stack, which the company says has processed trillions in stablecoin volume across dollar, Singapore dollar, and Brazilian real denominations, handles the stablecoin leg. The digital pound completes final settlement. "An exporter paid instantly in stablecoins while the importer settles in a digital pound, in a single flow," said Marc Boiron, CEO of Polygon Labs. "Interoperability is what gets value moving."

The convergence read-across

The experiment sits at the intersection of three forces reshaping global capital flows. First, the tokenisation of trade finance: institutions from JPMorgan to HSBC are already piloting blockchain settlement for corporate treasury, and the SME market, historically under-served because manual credit assessment is too expensive at that scale, is the logical next frontier. A reusable, machine-readable credit identity changes the unit economics of SME lending across every jurisdiction that adopts the standard.

Second, the geopolitics of digital currency rails. The IMF warning about dollarisation was directed at emerging markets, but it names a structural risk that the Bank of England is now testing responses to. If stablecoin-denominated trade finance becomes the default infrastructure, the currency that anchors final settlement acquires outsized systemic influence. The Digital Pound Lab is, in part, a sovereignty experiment: can sterling remain a meaningful settlement asset in a tokenised payments world, or does it get routed around?

Third, the regulatory legitimacy signal. Central bank sandboxes carry a different weight from private pilots. Polygon Labs gaining a seat inside the Bank of England's experimental programme normalises Layer 2 blockchain infrastructure as a component of regulated financial architecture, not a peripheral asset-speculation venue. For cross-sector investors watching both the digital-assets and fintech spaces, this kind of regulatory adjacency is now a due-diligence input, not a footnote.

The wider question is whether a successful Phase 2 outcome accelerates the Bank of England's timeline on a retail or wholesale digital pound. The Lab is explicitly exploratory, and no commercial launch is implied. But the design logic, two forms of money, one flow, with smart-contract-governed identity underneath, sketches a plausible architecture for the next generation of trade finance infrastructure, and positions sterling to remain inside it.
