EU DLT Pilot Regime: The Experiment That Showed What Tokenized Securities Need

In March 2023, the EU’s DLT Pilot Regime went live — a regulatory sandbox designed to allow DLT-based market infrastructures to operate under modified securities law, free from rules that assumed traditional centralized architecture. The European Commission’s theory was sound: existing EU securities law — the Central Securities Depositories Regulation, MiFID II, and the Settlement Finality Directive — had been written for conventional settlement systems. Applying those rules to blockchain-based settlement would impose compliance costs disproportionate to the technology’s developmental stage and might prevent useful innovation from emerging at all.

The Pilot Regime offered a temporary exemption. Companies that built DLT-based trading and settlement infrastructure could apply for authorization and operate within a sandbox with modified rules for up to six years. The experiment would generate evidence. ESMA would evaluate. The Commission would decide whether to make modifications permanent or let the regime expire.

Three years in, the results are instructive — but not in the way optimists hoped. Only three infrastructures received authorization. Volume was limited. The technical challenges proved significant. And yet ESMA’s June 2025 report recommended making the regime permanent and removing the volume caps that had constrained it — because the lessons learned were considered worth building on, even if the initial uptake was modest.

What the DLT Pilot Regime Waived

To understand why the DLT Pilot Regime was novel, it helps to understand what it waived.

EU securities law under the Central Securities Depositories Regulation (CSDR) requires that securities settlement occur through an authorized central securities depository (CSD). A CSD is a specialized financial market infrastructure — a regulated institution that holds securities in dematerialized form, processes settlement, and maintains the authoritative record of ownership. The rules governing CSDs are detailed, capital-intensive, and designed for centralized systems.

On a blockchain-based platform, the settlement record is maintained on the ledger — distributed across nodes, rather than held in a central database by a licensed CSD. An automated clearing mechanism handles settlement in code. The traditional CSD model is, at minimum, redundant and at maximum incompatible with the blockchain architecture.

The DLT Pilot Regime created a new category of authorized market infrastructure: the DLT multilateral trading facility (DLT MTF), the DLT settlement system (DLT SS), and the DLT trading and settlement system (DLT TSS) that combined both functions. These entities could operate under modified rules, including exemptions from CSDR requirements, subject to volume caps — each platform capped at €6 billion in market capitalization of outstanding instruments.

The regime also allowed “atomic settlement” — simultaneous, final delivery versus payment where the token representing the security and the token representing the cash change hands in a single on-chain transaction, eliminating the settlement lag and counterparty risk inherent in conventional T+2 settlement.

Who Applied and Who Was Authorized

The DLT Pilot Regime accepted applications from March 2023. Authorization requires home member state competent authority approval, coordinated with ESMA.

By June 2025, three infrastructures had been authorized. The limited number was a source of discussion in the industry and among policymakers. The authorization process proved time-consuming — competent authorities were navigating novel applications under regulatory guidance that was itself being developed in parallel with the first applications. Legal uncertainty, particularly around the interaction between the DLT Pilot Regime’s exemptions and other EU financial law, deterred some applicants.

Euroclear, the world’s largest securities settlement system, operated a DLT pilot platform for certain bond instruments. Deutsche Börse Group developed infrastructure under the pilot for tokenized securities trading. Bankex, a smaller fintech, received authorization in Luxembourg for a tokenized bond platform.

The participation of large incumbents like Euroclear and Deutsche Börse was read in two ways. Optimistically, it demonstrated that major market infrastructure operators were willing to invest in DLT-based systems — a signal that the technology was taken seriously. Pessimistically, it demonstrated that the compliance and technical requirements of the Pilot Regime favored well-resourced incumbents over innovative challengers — replicating in the DLT space the same concentration dynamics that characterized traditional securities infrastructure.

Why Uptake Was Limited

The Pilot Regime’s limited uptake reflected several structural constraints.

The volume caps were the most commonly cited obstacle. A €6 billion cap per platform meant that no single Pilot Regime platform could serve the full market for any significant asset class. For an institutional client considering which platform to use for settling tokenized bonds, the knowledge that the platform was subject to an artificial volume limit — and might need to either refuse new instruments or migrate to a different framework when the cap was approached — created real practical uncertainty.

The operational costs were a second constraint. Operating a DLT settlement system under the Pilot Regime required satisfying most of the same governance, cybersecurity, operational continuity, and capital requirements as a conventional CSD. The regulatory burden was reduced relative to full CSDR compliance, but not eliminated. For a startup DLT settlement provider without a CSD’s existing infrastructure and staff, the overhead was significant.

The liability regime created a third obstacle. EU securities law imposes strict liability on CSDs for settlement fails. The Pilot Regime’s modified rules did not fully resolve how liability would be allocated when DLT-based settlement failed — whether due to network congestion, oracle failures, or smart contract bugs. Institutional clients unwilling to accept novel liability risk were cautious about committing volume to Pilot Regime platforms.

ESMA’s June 2025 Recommendations

ESMA’s June 2025 report to the European Commission evaluated the Pilot Regime’s results and made several significant recommendations.

First, ESMA recommended that the Pilot Regime be made permanent rather than being allowed to expire. The evidence base, ESMA argued, was insufficient for a final assessment but sufficient to justify continuation. Pulling the regime after six years would require operators to either wind down their DLT platforms or convert to full conventional compliance — an outcome that would destroy the infrastructure investments already made and set back the development of tokenized securities markets in the EU by years.

Second, ESMA recommended removing the €6 billion volume cap or substantially raising it. The cap had been designed to limit systemic risk from a novel infrastructure type. ESMA concluded that the cap was now more hindrance than protection — that the Pilot Regime’s safeguards were sufficient to manage risk without an artificial volume ceiling.

Third, ESMA recommended expanding the range of instruments eligible for the Pilot Regime to include additional bond types and, potentially, equities — subject to further consultation. The original regime focused primarily on government and corporate bonds. Expanding to equities would be a significant step given the higher volumes and more complex settlement dynamics of equity markets.

Fourth, ESMA recommended additional guidance on the liability regime — addressing the uncertainty that had deterred institutional participation. Clearer rules about responsibility for settlement failures would reduce the legal risk premium that institutional clients were implicitly pricing into their Pilot Regime participation decisions.

What the DLT Pilot Regime Taught

The DLT Pilot Regime taught the EU — and, through ESMA’s public reports, the global regulatory community — several important lessons about what tokenized securities markets actually need.

Regulatory exemptions are necessary but insufficient. Removing CSDR requirements did not, by itself, generate a vibrant tokenized securities market. The structural obstacles — volume caps, liability uncertainty, operational costs, incumbent concentration — required specific attention.

Settlement finality matters more than settlement speed. The most valuable feature of DLT-based settlement is not speed per se but the combination of atomic delivery versus payment and programmable finality. The EU’s Settlement Finality Directive’s extension to DLT systems was a precondition for institutional adoption, because institutional clients require legal certainty that settled transactions cannot be reversed.

The public sector is a crucial customer. DLT-based bond issuances by the EU itself — EU green bonds settled on DLT platforms — and by member state debt agencies would provide the volume and institutional credibility that purely private sector activity has not yet generated. ESMA’s recommendations noted that public sector participation would be an accelerant for Pilot Regime platforms.

The regime’s modest uptake does not undermine its value. Three authorized platforms, limited volume, and a list of lessons learned is not failure — it is the expected output of a deliberately cautious experiment. The question is whether the EU has the political will to act on those lessons by making the framework permanent and removing the constraints that limited the experiment’s reach.
