Strategic perspective · September 2026 · By Julien Achard

Towards multi-rail finance

Sovereign stablecoin replication, tokenised deposits, CBDCs: why no single instrument will win everywhere, and what it means for Europe and for banks. A strategic perspective built on Arthur D. Little's “The Sovereign Stablecoin Era” and L'Agefi.

01Two dynamics, one trajectory

Tokenisation is entering its institutional phase. The point is no longer to prove that a blockchain can represent a bond, a fund share or a deposit, but to make these representations work within regulated finance: property rights, authoritative ledger, custody, compliance, settlement, liquidity, investor protection.

Stablecoins are becoming a sovereignty issue. USD stablecoins dominate internationally, but states and banks are developing local responses (national-currency stablecoins, tokenised deposits, CBDCs, instant payments) so that local payments and tokenised markets do not settle permanently in digital dollars.

02The dollar redeploys; stablecoins and tokenised deposits complement each other

Tokenised deposit volumes processed by J.P. Morgan.

Two questions are often confused. The settlement currency is decided by demand: the dollar anchors international settlement, local currencies dominate domestic use. The instrument is decided by where value flows: stablecoins win on small amounts and open networks, tokenised deposits on wholesale settlement.

Two different bets, but not two incompatible futures.After J. Roussel, L'Agefi, 2026

What technology does not solve on its own

  • Tokenisation does not create liquidity by design: the same security on several networks fragments order books.
  • Instant settlement is not always optimal: it increases intraday liquidity needs and removes netting benefits.
  • Blockchain does not replace institutional custody: banks, custodians, CSDs and transfer agents remain essential.
  • Technical interoperability is not enough: moving a token between two chains guarantees neither legal recognition nor agreement on the authoritative ledger.
  • The competitive edge is in orchestration: conversion between tokenised monies, compliance, liquidity, clearing, final settlement.

03Three postures for banks, a four-level target architecture

  1. The regional architectEngages early as issuance and custody partner for an instrument backed by a sovereign currency (FAB / DDSC).
  2. The corridor specialistTargets flows where stablecoin rails beat correspondent banking on cost (Standard Chartered / Zodia, Banking Circle, Lloyds, BTG Pactual).
  3. The infrastructure providerCaptures the institutional wholesale settlement layer (J.P. Morgan Kinexys, Citi Token Services).

DomesticLocal-currency stablecoins, tokenised deposits, possible CBDCPayments, treasury, local commerce, cash management
Capital marketsTokenised assets and tokenised settlement moneyCollateral, repo, funds, bonds, delivery versus payment

For Europe, the challenge is to build enough liquidity, acceptance and infrastructure around the tokenised euro so that European assets and payments do not structurally rely on the digital dollar. For banks, it is to stay at the heart of the system by combining tokenised deposits, regulated stablecoins, custody, compliance, liquidity and settlement.

Every posture is defensible. Waiting for regulatory clarity is not.Julien Achard, OpenbanQ
