Monument Bank Partners with Midnight to Tokenize £250M in UK Retail Deposits
UK FCA-regulated Monument Bank has announced a partnership with Midnight Network to tokenize up to £250M in retail customer deposits using Midnight's ZK selective disclosure model. The partnership satisfies AML and KYC regulatory requirements cryptographically, without requiring public data exposure.
Monument Bank, a UK-regulated digital bank authorized by the Financial Conduct Authority, has announced a formal partnership with Midnight Network to tokenize up to £250 million in retail customer deposits on Midnight's privacy-preserving blockchain infrastructure. The partnership represents one of the largest tokenized deposit programs announced by a regulated UK bank and the first major institutional deployment of Midnight's ZK selective disclosure model for retail financial services.
What Deposit Tokenization Actually Means
Tokenized deposits are on-chain representations of bank deposits denominated in a sovereign currency — in this case, British pounds. Unlike stablecoins issued by non-bank entities, tokenized deposits issued by a regulated bank carry the same legal claim against the issuer as a conventional deposit, including access to the UK's Financial Services Compensation Scheme up to the £85,000 protection limit. The token form enables programmable settlement, 24-hour transfer capability, and DeFi interoperability.
Monument Bank's deployment will allow retail customers to hold tokenized pound deposits in Midnight-compatible wallets. The ZK selective disclosure mechanism means that a customer can prove to a counterparty that they hold sufficient funds, or have passed KYC verification, without revealing their full account balance, transaction history, or identity details beyond what the specific transaction requires.
The FCA Regulatory Dimension
Monument Bank's FCA authorization is a critical element of this announcement. Regulated institutions operating tokenized deposit programs must demonstrate compliance with safeguarding requirements, customer data protection standards under UK GDPR, and anti-money-laundering obligations. Monument Bank's selection of Midnight's ZK model is in part a compliance architecture decision: selective disclosure allows the bank to satisfy regulatory data-sharing obligations with authorities while preserving customer privacy in commercial transactions.
The £250 million ceiling represents the retail deposit book being made available for the program, not a guaranteed deployment volume. Initial rollout will be to a segment of tech-forward retail customers in a structured pilot. The FCA has been briefed on the technical architecture, and Monument Bank has indicated the program operates within existing authorized activities rather than requiring new permissions.
Broader Implications for Midnight's Institutional Trajectory
The Monument Bank partnership answers a fundamental question institutional observers had been asking about Midnight: would regulated financial institutions actually adopt ZK privacy infrastructure in a jurisdiction with strong data protection law? The answer, from one FCA-regulated institution, is affirmative. This is the kind of reference implementation that unlocks follow-on conversations with other regulated banks in the UK, EU, and Commonwealth markets where FCA precedents carry weight.
