LEI-Backed Open Finance Prototype Shows How SMEs Can Cut Cross-Border KYC Delays and Compliance Costs

Cross-border business account opening and trade finance for small and medium-sized enterprises just got a credible technical blueprint. Project Aperta, led by the Bank for International Settlements (BIS) Innovation Hub Hong Kong Centre and the Global Legal Entity Identifier Foundation (GLEIF), has produced and tested a working prototype that links domestic open finance networks across the United Kingdom, the United Arab Emirates, Brazil, Hong Kong, and India through a single interoperability layer. When a company presents its Legal Entity Identifier (LEI), that credential can trigger automatic, real-time Know Your Business (KYB) and Anti-Money Laundering (AML) checks simultaneously across jurisdictions, eliminating the manual paperwork loops that currently add weeks to cross-border onboarding.

What Does the Project Aperta Prototype Actually Do?

The prototype builds a "network of networks": a neutral connectivity layer that sits above and connects existing domestic open finance frameworks without requiring each country to abandon its own standards. An end-user business authenticates itself with its LEI, a 20-character alphanumeric code maintained in the Global LEI System and verified by GLEIF-accredited issuers. That single credential then travels with payment messages and account-opening requests across borders, allowing receiving institutions to resolve the entity's identity instantly and automatically, rather than requesting fresh documentation from scratch.

The technical outcome matters because domestic open finance regimes across these five markets currently operate on incompatible data formats, trust frameworks, and API standards. Without an interoperability layer, a Brazilian SME seeking to open a trade finance account in Hong Kong must typically submit duplicated documentation to each intermediary, wait for manual review, and repeat the process every time it enters a new market. Research from Fenergo published in late 2025 found that average annual AML and KYC operational spend now reaches $72.9 million per institution globally, with UK corporate banks reporting onboarding timelines exceeding six weeks for new business clients. Project Aperta directly targets that friction.

Why Are SMEs the Focal Point?

Large multinationals absorb cross-border compliance costs more easily than smaller firms, which often operate without dedicated compliance teams or established correspondent banking relationships. According to the FSB's 2025 progress report on the G20 Cross-Border Payments Roadmap, average global remittance costs remain above 6% and broad improvements at the end-user level have been marginal since monitoring began in 2023. For SMEs, those costs are compounded by limited access to trade credit, letters of credit, and supply chain financing precisely because identity verification across borders remains labour-intensive and costly for correspondent banks to perform.

Project Aperta's prototype demonstrated two specific use cases: enabling a business to port its account and identity data to a foreign bank to open an account materially faster, and enabling the exchange of trade finance data such as shipping documents and payment histories to accelerate the processing of letters of credit and electronic bills of lading.

How Does the LEI Connect to Existing Compliance Frameworks?

The LEI is not new. Introduced after the 2008 financial crisis at the direction of the Financial Stability Board, it has been mandatory for entities participating in derivatives and securities markets in most major jurisdictions for over a decade. What Project Aperta advances is the LEI's role as a portable identity attribute in open finance API flows, rather than a field on a static regulatory report.

That positioning builds on a chain of prior endorsements. The Financial Action Task Force (FATF), the BIS Committee on Payments and Market Infrastructures (CPMI), the Wolfsberg Group, and the Swift Payment Market Practice Group (PMPG) have all previously signalled support for LEI inclusion in cross-border payment messages. Project Aperta converts that policy appetite into a functioning technical prototype, demonstrating the mechanics rather than merely recommending them.

The project was conducted with the regulatory endorsement of the Hong Kong Monetary Authority, the Central Bank of Brazil, the Central Bank of the UAE, and the UK Financial Conduct Authority, alongside the International Chamber of Commerce Digital Standards Initiative and the HKU Standard Chartered Foundation FinTech Academy. Commercial banks and fintechs participated in testing.

What Are the Implications for Digital Assets and Tokenised Finance?

GLEIF and BIS identify a secondary implication beyond traditional open finance: the prototype architecture points toward how the LEI could support regulatory oversight in digital asset ecosystems. As tokenised versions of real-world assets begin to cross jurisdictions, financial institutions, digital asset platforms, and regulators each need a common method to verify the legal entity standing behind a transaction. An LEI embedded in a cross-border digital asset transfer would function as a direct link to auditable, verified entity data, supporting transparency and risk management without requiring bespoke identity infrastructure for each platform. That application is still prospective, but Project Aperta provides the technical proof of concept.

Where Does This Fit Against the G20 Roadmap Timeline?

The G20 Cross-Border Payments Roadmap sets 2027 as the deadline for achieving cheaper, faster, and more transparent international payment flows, including a target that 75% of cross-border payments reach beneficiaries within one hour. The FSB's own 2025 monitoring report acknowledged that improvements have not yet reached end-users at scale. Project Aperta directly addresses two of the roadmap's identified pain points: reducing KYB friction for businesses and cutting the compliance burden on cross-border payment messages. The five-jurisdiction scope and central bank participation suggest this is being positioned as a template, not just an experiment.

Why This Matters to FinanceX Readers

For finance professionals and investors, Project Aperta sits at the intersection of regulatory infrastructure and commercial opportunity. Compliance technology vendors, correspondent banks, and open finance platforms that integrate LEI-based identity flows early gain a structural cost advantage as jurisdictions move toward mandating cross-border interoperability. Fenergo's data showing $72.9 million average annual KYC spend per institution underscores the scale of the addressable efficiency gain. Investors tracking the regtech and open banking segments should note that regulatory proof-of-concept work backed by four central banks and the BIS carries a different weight than vendor pilots: it indicates where standards are forming, not just where technology is available.
