European Central Bank Concludes Tokenization Testing Phase

The European Central Bank (ECB) has recently concluded a series of exploratory tests on the tokenization of financial assets. These initiatives, conducted in collaboration with major financial institutions, aimed to assess the feasibility and limitations of integrating distributed ledger technologies (DLT) into the settlement of financial transactions.

The ECB played a central role in these tests by providing a settlement asset within the tokenized ecosystem: the wholesale central bank digital currency (wCBDC).

The successful implementation of tokenized asset settlement could lead to more efficient, transparent, and secure financial markets while reducing costs and improving accessibility to capital markets.

In response to the growing interest in DLT for settling wholesale transactions, the ECB launched exploratory work to assess various interoperability solutions between TARGET Services and DLT platforms. The primary objective was to ensure that central bank money remains a reliable settlement asset within evolving financial infrastructures.

Between May and November 2024, the Eurosystem exploratory tests processed more than 200 transactions totaling €1.59 billion, involving 64 participants, including central banks, financial market players, and DLT operators.

The Eurosystem reviewed three different interoperability approaches: Trigger Bridge with Deutsche BundesBank, TIPS Hash Link with Banca d’Italia, and Full DLT Interoperability with Banque de France.

Some solutions enabled external DLT platforms to connect with the ECB's TARGET services, including the T2 real-time gross settlement system, to settle transactions in central bank money.

A concrete example of these tests was the primary issuance of bonds by financial institutions, corporations, and a sovereign state, settled via wholesale central bank money during delivery versus payment (DvP). One notable outcome was the recent issuance of Caisse des Dépôts: France First Tokenized Bond in Digital Euro, which highlights one the DL3S soltuion developed and operated by the Banque de France.

The tests conducted by the ECB are now complete, paving the way for a crucial conclusion phase. This phase will involve an in-depth analysis of the test results to draw lessons for the future integration of DLT into financial market and settlement infrastructures. Several scenarios are possible:

• A new testing phase could be initiated to explore more specific aspects of tokenization or to trial new solutions.
• The ECB could issue guidelines for the implementation of tokenization in the coming years.

The ECB is committed to supporting the adoption of tokenization in a safe and efficient manner while ensuring the preservation of financial stability. The final decision on how to proceed will be made after a thorough analysis of the test results.

National central banks are now gathering evidence from these tests to assess their solutions and present conclusions about the functional features of tokenized financial systems.
