Swift’s blockchain-based ledger is live and already being used by some large global financial institutions, CEO Javier Pérez-Tasso said at Sibos 2026. At least 19 banks are expected to adopt it by the end of this year, using tokenized deposits (bank deposits represented digitally on blockchain networks) across five major currencies to support 24/7 payments. Swift announced development of the ledger at last year’s Sibos conference.
