The Prudential Regulation Authority is the United Kingdom's prudential regulator and a part of the Bank of England since the 2013 regulatory reorganisation that succeeded the Financial Services Authority. PRA supervises the prudential side of UK-authorised banks, building societies, credit unions, insurers, and major investment firms, applying capital, liquidity, and risk-management rules derived from Basel and PRA-specific UK rulebooks. For tokenisation, PRA is the binding prudential constraint on any UK bank's tokenisation programme: it applies the Basel SCO60 cryptoasset standard to UK bank exposures, supervises tokenisation programmes at UK GSIBs (HSBC, Barclays, Standard Chartered, NatWest, Lloyds), and jointly runs the UK Digital Securities Sandbox with the Bank of England and FCA. For an operator with any UK bank-issued tokenised deposit or tokenisation programme involving balance-sheet exposure, PRA sits on the supervisory map.
What they do
PRA is the microprudential supervisor for UK banks, building societies, credit unions, insurers, and major investment firms. It sits inside the Bank of England's governance structure but has its own statutory objectives focused on safety and soundness of regulated firms and policyholder protection for insurers. It is the prudential counterpart to FCA's conduct supervision: dual-regulated firms (banks, insurers, major investment firms) deal with both, while smaller investment firms and most non-bank financial services firms deal with FCA only.
Tokenisation footprint
- Joint operator of the UK Digital Securities Sandbox under FSMA 2023, with the Bank of England and FCA. PRA leads on prudential supervision where the participant is PRA-authorised or where the activity carries balance-sheet implications.
- Implementer of the Basel SCO60 cryptoasset prudential standard for UK bank exposures to crypto-assets. SCO60 distinguishes Group 1 assets (tokenised traditional assets meeting classification conditions, treated under existing prudential rules) from Group 2 assets (other crypto-assets, attracting the punitive risk weight); PRA's transposition determines which UK bank tokenisation programmes sit on a tractable capital footing and which do not.
- Prudential supervisor for the UK's largest banks running tokenisation programmes, including HSBC, Barclays, Standard Chartered, NatWest, and Lloyds. Tokenised deposits issued by PRA-authorised banks remain under conventional deposit-liability prudential treatment and sit outside the DSS perimeter, although they can serve as the cash leg for DvP against DSS-issued securities.
- Supervisor of insurers including those holding or potentially allocating to tokenised assets. The Solvency II UK regime applies to any insurer's tokenised-asset exposure, and PRA capital treatment is the binding constraint on insurer allocator demand for tokenised products.
Regulatory positioning
PRA's statutory perimeter sits inside the UK regulatory architecture established by the Financial Services Act 2012, which split the former FSA into a conduct regulator (FCA) and a prudential regulator (PRA, embedded inside the Bank of England). PRA's primary objective is the safety and soundness of the firms it regulates, with a secondary competition objective. Its rulebook combines onshored Basel and Solvency II provisions with PRA-specific UK overlays, and its supervisory approach is forward-looking, judgement-based, and firm-specific rather than rule-by-rule mechanical.
On tokenisation, PRA has been more permissive than its rule-making would suggest. It has invited tokenised-deposit pilots from authorised banks under existing prudential treatment rather than waiting for a bespoke regime, and it has signalled willingness to work through DSS conditions case by case rather than publishing a uniform tokenisation supervisory expectation. The binding constraint is SCO60: any programme that survives the Group 1 classification test operates under existing capital rules, while anything classified as Group 2 attracts a risk weight that effectively makes the activity uneconomic at scale.
PRA does not legislate the perimeter; HM Treasury sets the legislative envelope through FSMA 2023 secondary legislation and PRA fills it out with rules. A UK bank issuing a tokenised investment product to retail will engage both PRA (capital) and FCA (conduct), with the DSS on the venue side if the issuance touches sandbox infrastructure.
Open questions
- Whether PRA will publish a standalone tokenised-deposit supervisory statement, or continue to handle pilots through existing prudential channels.
- Final UK transposition of the Basel SCO60 cryptoasset standard and any PRA-specific overlay on Group 1 classification conditions.
- Capital treatment for UK insurers holding tokenised investment products under Solvency II UK, particularly for tokenised money market funds and tokenised private credit.
- How PRA treats UK GSIB participation in cross-border tokenised-deposit consortia (e.g. Partior, Kinexys cross-bank rails) for the purposes of large-exposure and operational-resilience supervision.
