The Ledger Problem: Why Tokenisation Cannot Override the Laws of Finance

Tokenisation has become one of the most discussed ideas in modern finance, promising to make markets faster, cheaper, and more accessible by recording ownership of bonds, equities, real estate, and other assets on programmable digital ledgers. Regulators, central banks, and major financial institutions have each dedicated significant resource to exploring its potential. The enthusiasm is understandable. The conclusions being drawn from it are, in some important respects, premature.

The core argument in favour of tokenisation rests on efficiency gains: atomic settlement that eliminates counterparty exposure during the clearing window, continuous liquidity management made possible by smart contracts, and embedded compliance that automates regulatory checks at the point of transfer. These are genuine and meaningful improvements to financial market plumbing, and the technology, in controlled environments, has demonstrated it can deliver them.

What tokenisation cannot do, however, is suspend the underlying laws of finance. A tokenised bond is still a bond. The issuer can still default. The collateral posted against a tokenised lending position still needs to be valued, margined, and liquidated according to the same economic logic that governs any secured transaction. Changing the ledger on which a claim is recorded does not change the nature of the claim itself.

Legal entitlement is perhaps the most acute area of unresolved tension. Regulators and legal scholars have increasingly noted that the biggest risk in tokenisation is a confusion between technical possession and legal ownership. If the token, the custody chain, the transfer agent record, and the underlying documentation do not perfectly align, an investor may hold something that economically resembles the target asset without actually holding the rights they believe they have purchased.

The United States Securities and Exchange Commission addressed part of this ambiguity in January 2026, clarifying that the format in which a security is issued — including its representation as a token — does not alter the application of federal securities law. Tokenised securities are still securities. That clarification is helpful, but it also illustrates the point: the existing legal architecture reaches into the new format and governs it, not the reverse.

Settlement finality presents a second layer of complexity. Proponents of blockchain-based settlement argue that atomic, delivery-versus-payment transactions eliminate the gap between trade execution and final settlement. In narrow technical terms, they are right. But finality in the legal sense requires more than a confirmed on-chain transaction; it requires that the transfer be recognised as irrevocable under the relevant insolvency regime, which varies by jurisdiction and has not been harmonised across major markets.

Liquidity risk is a third area where optimism has outpaced evidence. Tokenisation can lower the barriers to trading illiquid assets by fractionalising ownership and enabling round-the-clock markets, but it does not manufacture liquidity where none structurally exists. Thin secondary markets for tokenised private credit or real estate can become disorderly under stress just as their traditional equivalents do — and the speed enabled by the technology may, in such conditions, accelerate rather than cushion the dislocation.

The International Monetary Fund has noted that absent clear policy frameworks and safe settlement assets, tokenisation risks amplifying financial instability through speed, concentration, and fragmentation. That is not an argument against the technology; it is an argument for treating it with the same analytical rigour applied to any other financial innovation.

Tax treatment remains a further unresolved question across most jurisdictions. How transfers, income distributions, and realised gains on tokenised instruments are classified and reported is still subject to guidance that is, in many markets, provisional or absent altogether. Investors and issuers building positions at scale are, to some degree, making assumptions about a framework that does not yet fully exist.

None of this forecloses a constructive future for tokenisation. The technology is real, the efficiency gains are measurable in the contexts where it has been piloted, and the regulatory infrastructure is beginning, slowly, to catch up. But the ledger is not a magic wand. Markets that proceed as though moving an asset on-chain transforms its fundamental risk profile will, eventually, be reminded by the oldest mechanism in finance — loss — that it does not.
