Swift’s $1.5 Quadrillion Network Confronts Blockchain Challenge

Swift connects more than 11,500 financial institutions across over 200 markets, underpinning a network estimated to carry about $1.5 quadrillion in transactions annually. Its new Ethereum-compatible ledger is designed as an orchestration layer linking tokenized deposits issued on banks’ own systems. Final interbank settlement will continue through existing infrastructure, allowing lenders to retain compliance, credit and risk controls rather than replacing Swift or the banking system.

Swift said on July 9, 2026, that the ledger was ready for initial use, about nine months after unveiling the project on Sept. 29, 2025. Seventeen banks from six continents—including Citi, HSBC, Standard Chartered, UBS and Wells Fargo—are preparing to pilot live transactions. The trial will test whether tokenized deposits can move between institutions around the clock, including overnight and on weekends, while meeting the resilience, scalability and regulatory standards required for global payments.

Swift is a cross-border financial messaging network connecting more than 11,500 financial institutions across over 200 countries and territories. Its shared ledger uses a unified coordination layer to link tokenized bank deposits and could eventually extend to CBDCs and regulated digital assets, reducing platform fragmentation and supporting round-the-clock cross-border payments.

Swift announced on March 30, 2026, that it had completed the design and moved into the minimum viable product stage, using Hyperledger Besu to build an EVM-compatible architecture. On July 9, it said the ledger was ready for initial use, with 17 banks across six continents—including Citi, HSBC and UBS—set to pilot live transactions. Final settlement will continue through existing systems, and no investment amount has been disclosed.
