Tokenised Securities Get Bank Capital Parity by Letter, on a Legal Test the Rulebooks Leave Open
UK and EU supervisors say banks may hold tokenised securities at the capital cost of the paper equivalent, as an interim position pending the Basel review. The condition, identical legal rights, is undefined in law. Banks, custodians and collateral desks are exposed.

The consensus in October 2026 is that tokenisation has won the policy argument: supervisors say a tokenised bond should cost the same capital as a paper one. On our reading, the weak signal sits underneath: parity has arrived by supervisory letter, not by rule. The Prudential Regulation Authority treats its position as interim and expects to consult in 2028 at the earliest (Bank of England, 18/05/2026), the Basel Committee promises only an update by the end of 2026 (Bank for International Settlements, 01/10/2026), and the European Banking Authority says the missing EU definition of a financial instrument “can only be remedied by legislative action” (European Banking Authority, 24/09/2026). A bank pricing tokenised exposures today relies on a legal test nobody has defined.
Signal Identification
A regulatory pivot: capital parity for tokenised securities is granted conditionally and provisionally. The condition, rights identical to the underlying security, depends on legal classification the EU has not harmonised, and five jurisdictions apply the Basel crypto standard five ways.
What's Changing
The Basel Committee “advanced its review and expects to provide an update by the end of the year” (Bank for International Settlements, 01/10/2026). Its implementation date was 1 January 2026, yet Hong Kong has implemented it, the EU partially, Canada with targeted changes, Singapore has delayed and the US will not implement it in current form (Ashurst, 06/10/2026).
Parity rests on letters. The PRA says tokenised traditional assets “would, in general, receive the same prudential treatment as their non-tokenised equivalents”, where “the legal rights conferred are identical and the underlying risks are comparable” (Bank of England, 18/05/2026). The EBA says EU banks treat a tokenised traditional asset as the asset it represents (Article 501d), but if tokenised instruments stopped being financial instruments, “it is unclear how those exposures should be treated”, including for hedging and netting (European Banking Authority, 24/09/2026).
The market is small. The IMF says tokenized markets “are growing rapidly but remain very small and fragmented”: repo averages around $300 billion to $350 billion daily against about $13 trillion in the US repo market (International Monetary Fund, 08/10/2026), roughly 2% to 3% on our arithmetic. The Bank of England adds that “a tokenised security needs a legally authoritative record” (Bank of England, 01/10/2026).
Five jurisdictions, five treatments of the Basel crypto standard, with the answers due from 2026
Left: jurisdictional treatment (Ashurst, 06/10/2026). Right: Basel Committee (BIS, 01/10/2026), OCC final rule (OCC, 23/10/2026) and PRA letter (Bank of England, 18/05/2026).
Disruption Pathway
On the available evidence the path has three stages. First, the Basel Committee publishes its update by the end of 2026, and the Bank of England says “later this year, we will publish a full Roadmap” (Bank of England, 01/10/2026). Second, in 2027 jurisdictions decide whether to follow; the US has finished a capital rule for stablecoin issuers, effective 18 January 2027, not for tokenised securities (Office of the Comptroller of the Currency, 23/10/2026). Third, from 2028 the PRA consults, and any rule must say what makes rights “identical”; until then each bank sets its own reading.
Stress concentrates in netting and hedging, where the EBA finds treatment unclear if a token loses financial-instrument status, and in cross-border booking, where the same token meets different standards in Hong Kong, the EU and the US. Two adaptations follow. Operationally, banks should file a legal opinion per tokenised asset class on why its rights match the paper security. Financially, collateral desks should price capital at the stricter of the booking jurisdictions until a rule fixes the test.
Why This Matters Now
This lands on chief risk officers, heads of treasury and collateral, custody heads and the boards that approve tokenisation pilots. The assumption to revise is that technology neutrality settles the cost of a tokenised position. It does so only where legal rights are identical, and no rule-maker has said how a bank proves that. A token classed as an unbacked cryptoasset would face a 100% capital requirement under the PRA’s interim position (Bank of England, 18/05/2026), and a trading-book hedge could lose netting if classification shifts. Test tokenised repo and collateral business cases at parity and at a stricter treatment, committing after the Basel update and PRA consultation.
Decision-action posture for this signal: Prepare: model tokenised exposures at parity and at a stricter treatment now, and commit capital once the Basel update and the PRA consultation fix the legal-rights test.
Counter-Argument
The strongest objection is that parity already works and the volumes are too small to bind. The EBA says EU banks already apply it under Article 501d (European Banking Authority, 24/09/2026), and the PRA reaches the same result in the UK (Bank of England, 18/05/2026). The IMF calls tokenized markets “very small and fragmented” (International Monetary Fund, 08/10/2026), so a definitional gap touches few balance sheets, and the Basel update may simply confirm parity (Bank for International Settlements, 01/10/2026).
The objection is right that parity is the working rule. It does not answer the conditions attached: the PRA’s treatment holds only where rights are identical, and the EBA says harmonising the definition needs legislation. Tokenised volume is concentrated in repo, where netting decides the cost, so small size understates the exposure. Our reading is that parity holds for plain tokens and is untested for structured ones.
Implications
The shift is durable if tokenised securities scale, because capital will then follow each token’s legal classification, not the technology. The inflection window runs from the Basel update at the end of 2026 to the PRA consultation in 2028. On our reading, banks with documented legal sign-off on token rights and custodians whose records the law treats as authoritative position to gain; banks that booked tokenised exposures assuming technology neutrality lose most. The Bank of England letter (Bank of England, 18/05/2026) is the canonical statement of conditional parity.
Early Indicators to Monitor
- The Basel Committee update, due by the end of 2026, states a test for when a tokenised security is treated as its traditional equivalent.If this happens: The legal-rights test is being set globally; move capital plans from Prepare toward Decide.
- The Bank of England roadmap, due before 31 December 2026, names the date of the PRA consultation.If this happens: Capital timing becomes plannable; align pilot approvals with that date.
- The European Commission tables a legislative change to the definition of ‘financial instrument’ before the end of 2027.If this happens: The EU legal basis for parity is being fixed; expect netting treatment to settle in 2028.
- A bank discloses a capital cost for tokenised securities that differs from the paper equivalent in its Pillar 3 report.If this happens: Parity is not holding in practice; re-price comparable positions there.
- A US banking agency proposes capital for banks’ digital-asset holdings, beyond issuers, before the end of 2027.If this happens: The US is moving toward its own rule; map booking location against it.
Disconfirming Signals
- The Basel update gives tokenised traditional assets the non-tokenised capital treatment with no legal-rights condition.
- The EU adopts a harmonised definition of financial instrument that covers tokenised forms before the end of 2027.
- The PRA opens its consultation before the end of 2027, not in 2028.
- A supervisor publishes a list of token structures it treats as meeting the identical-rights condition.
- Tokenised repo volume falls below $300 billion a day in the IMF’s next estimate.
Strategic Questions
- Should 2027 tokenisation business cases assume capital parity, or the stricter treatment until the PRA consults?
- Who signs the legal opinion that a tokenised security’s rights match the paper one, and by when?
- Which of our current activities looks least wise if this signal lands?
