- Isabel Schnabel called for central bank reserves to be issued on blockchain infrastructure.
- The ECB warned that dollar stablecoins could become Europe’s default settlement layer.
- Project Pontes opens its pilot ecosystem on September 21, 2026.
- MiCA’s transitional grandfathering period ended on July 1, 2026.
ECB Executive Board member Isabel Schnabel used her 28 August appearance at the Jackson Hole Economic Policy Symposium to deliver a speech titled “Central banks on-chain”, in which she argued that central bank money has to move onto distributed ledgers or forfeit its role as the anchor of the financial system. Her reasoning rests on a mismatch that is already visible: securities, funds and other real-world assets are migrating to tokenized formats, while the cash leg that settles them stays locked inside legacy plumbing. The cash leg is simply the payment side of a trade, the euros that have to move when the asset moves. Fill that gap with private USD-denominated stablecoins, Schnabel warned, and European monetary sovereignty erodes by default rather than by decision.

Stablecoins can settle a trade but cannot print liquidity at 3am
Wholesale settlement in the euro area runs on claims against the central bank, an asset with no credit risk and no liquidity ceiling. That property is what makes it the anchor. A tokenized bond that settles against a private stablecoin swaps a risk-free leg for an issuer’s promise, backed by reserves that MiCA forces to be fully segregated but that still cannot be expanded on demand during a stress event. Schnabel’s argument turns on exactly that limitation. Stablecoins can carry retail and niche institutional flow, yet no amount of collateral quality lets them act as lender of last resort.
Atomic settlement is the practical prize. When cash and asset live on the same programmable ledger, delivery and payment execute in a single indivisible operation, which removes the window in which one side has performed and the other has not. For cross-border repo and securities financing, where that window currently costs collateral buffers and intraday credit lines, the saving is measurable rather than theoretical.
Schnabel offered three designs and endorsed none of them
The first route issues tokenized reserves natively on a programmable ledger, public or permissioned. The second keeps reserves where they are and builds synchronization triggers or bridges into external blockchain platforms, which is precisely what Pontes tests. The third delegates tokenization to private intermediaries operating dedicated omnibus accounts at the central bank.
Each option answers a question the ECB has not settled: how much of the settlement stack should the Eurosystem operate itself. Bridges preserve the existing TARGET architecture and keep the central bank out of ledger governance, at the cost of leaving the token layer in private hands. Native issuance does the opposite. Appia exists because that choice needs several years of legal groundwork before anyone commits to it.
September 21 is a stress test of the T2 trigger, not a launch
Pontes puts registered platform operators through DLT-based transactions whose cash leg is triggered against T2, while the ECB watches whether the synchronization mechanism holds under realistic volumes and failure conditions. Clearstream brings post-trade scale, SWIAT and Cashlink bring issuance platforms already used for German digital securities, and Axiology covers the smaller-market end.
The results feed the case for or against a permanent wholesale facility. Banks reading this correctly will treat September as the point at which tokenized issuance in euros stops being a pilot-desk curiosity and starts competing for balance sheet. The design being tested is not speculative. Between May and November 2024 the Eurosystem ran exploratory work with 64 participants and more than 50 trials and experiments, and Pontes carries those components forward.
The ECB needed a licensed perimeter before it could talk settlement rails
Schnabel is building on a regulatory base that only finished settling weeks ago. With the grandfathering window closed since July 1, any crypto-asset service provider still operating in the EU without a full MiCA licence is legally exposed, and the population of counterparties eligible to touch tokenized euro infrastructure is now a known, licensed set. That is what makes a wholesale conversation possible at all. A central bank does not connect settlement rails to an undefined perimeter.
The tokenized real-world asset segment sits in the harder spot. A tokenized bond is a security under MiFID II and a token under MiCA, and the two regimes were not drafted with each other in mind. Firms structuring these products currently absorb the cost of proving compliance twice, which is one reason issuers have been slow to move beyond pilot-scale deals.
Custodians that skipped Pontes now decide how far behind to fall
Banks with euro settlement operations have a dated event to plan against rather than a consultation paper. Custodians and CSDs that did not register as Pontes operators face a choice between joining the second wave and watching competitors accumulate operational experience with T2-linked DLT settlement. Stablecoin issuers targeting euro-denominated institutional flow lose their strongest argument, which was the absence of any public alternative on-chain.
The legislative track is where the timeline could slip. Pontes runs on existing Eurosystem authority as an experiment, but a permanent wholesale facility with programmable reserves requires legal instruments that do not yet exist, and Appia’s 2028 blueprint date reflects that. Whether the retail digital euro regulation clears the European Parliament before that pilot begins will also shape how much political capital remains for the wholesale side.
