Project Pontes cash tokens lack settlement finality until 2027 ECB upgrade
Key points
- Project Pontes launches in September with two settlement options: a wCBDC-like cash token on the Eurosystem's DLT and a trigger solution linked to TARGET2.
- Settlement finality for Pontes cash tokens is governed by the TARGET Guideline and is only achieved upon a defunding event back to the T2 account, not during intraday on-chain transfers.
- At launch, automatic defunding to T2 occurs only at end of day, meaning intraday token transfers between institutions do not carry final settlement under the current legal framework.
- The ECB has signalled a framework upgrade targeting mid-2027 to address the settlement finality shortcoming of the cash token option.
- Pontes cash tokens are a TARGET2-linked proxy for central bank money, not a true wholesale CBDC, which is why the trigger solution may prove more operationally attractive in the near term.
Project Pontes, the Eurosystem’s dual-settlement mechanism for distributed ledger technology (DLT) transactions, is scheduled to launch in September offering two cash-leg options: a wholesale central bank digital currency (wCBDC)-like cash token on the Eurosystem’s own DLT, and a trigger solution connecting DLT activity to the TARGET2 (T2) payment system. Despite the apparent appeal of the on-chain token option, the trigger solution may attract more institutional uptake in the early period, primarily because of how settlement finality is handled under the current legal framework.
The distinction turns on a structural limitation of the Pontes cash tokens. Although they are minted against balances held in a dedicated T2 account and can circulate freely on-chain through multiple intraday transfers between institutions, none of those transfers constitutes final settlement. Finality under the Pontes framework is governed by the TARGET Guideline and is only achieved when a defunding event returns value to the T2 account, which burns the tokens. At launch, that defunding occurs automatically only at end of day, meaning intraday on-chain transfers carry counterparty exposure that a true wCBDC transfer would not.
The ECB has signalled an intent to address the finality gap with an upgrade expected around mid-2027. Until then, the trigger solution, which achieves finality when the corresponding T2 transaction completes, offers a cleaner legal position for institutions where irrevocability of the cash leg is a prerequisite. The Pontes cash token is, in the ECB’s own framing, a TARGET2-linked proxy for central bank money rather than central bank money itself, and that distinction carries real operational weight.
