Citable research brief

Core conclusion · Tlines extraction

Citi argues that interoperability, not platform capability, is the binding constraint on institutional digital finance. Banks have invested over $100B in blockchain since 2020, producing parallel networks, fragmented liquidity and assets that do not move with the fluidity of the value they represent. The report expects a hybrid, non-linear transition in which legacy systems, private ledgers and public blockchains coexist. Programmability — self-executing payments, automated servicing, embedded compliance — is presented as complementary to interoperability; together they may deliver efficiency gains gradually rather than immediately.

Key arguments

Interoperability across data, technology and liquidity is the structural prerequisite for institutional scale, not a later-stage refinement.
Programmability lets on-chain securities and funds carry their own rules, obligations and servicing logic as they move between platforms and jurisdictions.
The near-term path to tokenized markets is unlikely to be linear; a hybrid environment of legacy systems, private ledgers and public blockchains should persist and benefits should accrue gradually.
Client demand for these foundations is present and growing now, so build-out is a response to current need rather than anticipation of a future state.

Key numbers

Bank blockchain investment since 2020: more than $100B
Blockchain deals analyzed in cited study: over 10,000
Global finance leaders surveyed: over 1,800
Banks set to pioneer tokenized cross-border payments on Swift ledger: 17

Main risks

Fragmentation persists: parallel networks and liquidity pools spread across intermediaries keep digital assets from moving as fluidly as the value they represent.
Interoperability requires coordination among rival institutions and jurisdictions; competing settlement money dynamics could delay a shared routing layer.
Timing risk: benefits from tokenization and programmability may accrue gradually, so near-term returns on the $100B-plus invested may disappoint.
