ECB study finds tokenised bonds lowered borrowing costs but not operational costs

What happened

The ECB's Macroprudential Bulletin of 13 April 2026 carried "Tokenised bonds: assessing efficiency and liquidity in a nascent market" by Alexandra Born, Johanne Evrard, Claudia Lambert, Wagner Eduardo Schuster and Anna Tskhakaya. The authors built a dataset of European corporate bonds and used matching procedures to compare tokenised issues against conventional issues with similar characteristics. The finding was mixed. Tokenised bonds were associated with lower borrowing costs and better market liquidity than their conventional matches, but the authors found no visible reduction in operational costs, which is the efficiency claim most often made for the technology. They stressed the market remains small and that larger benefits may only appear at scale, and identified central bank support for distributed ledger settlement infrastructure as a condition for growth. A companion article in the same issue, "Towards an efficient and integrated digital capital market in Europe: the role of tokenisation and the Eurosystem's policy response", addressed the fragmentation of European market infrastructure and the Eurosystem's policy options.

Why it matters

The result inverts the usual argument. Tokenisation has been sold primarily on back-office savings, and the ECB's matched comparison finds those savings absent while the measurable gains sit in pricing and liquidity, which points to a wider investor base or a novelty premium rather than to cheaper plumbing. Issuers building a business case on operational cost reduction have to reconcile that with this evidence. The policy conclusion is the more consequential part. By naming central bank settlement infrastructure as a condition for the market to scale, the ECB ties the future of tokenised European debt to the Eurosystem's own decisions on settling tokenised transactions against central bank money, rather than to private-sector adoption alone.

What is not settled

The study covers European corporate bonds only; the sample size, matching criteria and whether the borrowing-cost advantage reflects investor demand or issue selection are set out only in the primary article.
