Should central banks prioritize creating standardized, interoperable systems for all international digital payments?
Bank of Greece Deputy Governor Christina Papaconstantinou urged central banks on October 2, 2026, to prioritize interoperability in cross-border payment networks. The address highlights efforts to ensure global systems remain integrated rather than fragmented.
Why it matters
Interoperability serves as a vital strategic safeguard against the fragmentation of international payment systems. This approach aligns with the broader G20 roadmap, which seeks to make global transfers faster, cheaper, and more inclusive.
The Eurosystem plans to release an Appia blueprint for a tokenized wholesale financial ecosystem in 2028. This follows the 2026 activation of the TIPS cross-currency service, which now supports settlement between euros, Danish kroner, and Swedish kronor.
The players
Christina Papaconstantinou
She serves as the Deputy Governor of the Bank of Greece and oversees central banking policy.
Eurosystem
This entity comprises the European Central Bank and the national central banks of the member states that have adopted the euro.
The details
The Eurosystem is currently developing the Appia project to integrate tokenization and distributed ledger technology into the financial ecosystem. The TIPS service already enables instant settlement using central bank money, including features for non-euro area interactions.
Timeline
June 2025: TIPS enabled interactions with non-euro fast-payment systems.
October 2025: A cross-currency technical solution was implemented in TIPS.
June 2026: The TIPS cross-currency service was formally activated.
October 2, 2026: Christina Papaconstantinou delivered her remarks in Roda de Berà.
2028: The Eurosystem expects to deliver the final Appia blueprint.
Market Dynamics
These initiatives follow the strategic goals set by the G20 cross-border payments roadmap to improve global transfer efficiency. The ongoing push for interoperability marks a departure from fragmented legacy systems toward a unified digital future.
Enhanced interoperability aims to reduce the costs and processing times associated with international financial transactions. These upgrades facilitate more efficient capital flows for both institutional and individual cross-border market participants.
The takeaway
The move toward a unified tokenized ecosystem suggests a future where international transfers function as seamlessly as domestic payments. Market participants should monitor the 2028 Appia blueprint release to understand how tokenization will reshape wholesale financial market infrastructure.
What happens next
The Eurosystem is scheduled to deliver the Appia blueprint for a tokenized wholesale financial ecosystem in 2028.
