For many years, it seemed that the old guard (SWIFT) and the new wave (blockchain) were destined to coexist. However, the results of tests completed in January 2026 and the subsequent announcement on March 31st changed everything dramatically. SWIFT is not simply testing distributed ledger technology (DLT) - it has officially begun building a production infrastructure for tokenized assets.
Blockchain assets (tokenized bonds, stocks, stablecoins) exist in their own ecosystem, while banks operate on legacy systems and the ISO 20022 standard. Transferring assets from blockchain to traditional clearing is time-consuming, expensive, and error-prone.
This is precisely the problem that the previous phase of SWIFT testing addressed.
Key test results (which will now form the core):
Straight-through processing - Tokenized bond transactions (coupon payments, redemptions, and DVP transactions) were successfully completed.
Unified standard - Blockchain data is packaged in an ISO 20022 envelope, easily understood by any bank. No core banking system changes are required a critical requirement for implementation.
The role of AI - At the Sibos 2025 conference, AI was demonstrated extracting data from financial statements. Network participants validate it, creating a "golden record." This completely eliminates the need for manual data reconciliation between banks.
March 31, 2026, was a historic day. SWIFT announced the start of development of a blockchain-based shared ledger.
Practical implications:
24/7/365 operation: Cross-border payments will no longer have to wait for US banks to open on Monday morning. The network will operate around the clock.
The system is built on the Hyperledger Besu framework, which is fully compatible with the Ethereum Virtual Machine (EVM). This is a strategic decision: in the future, banks will be able to interact with public blockchains (Ethereum and L2 networks) as easily as with internal databases.
Let's look at the benefits:
1. Benefits for banks and depositories:
Reduced operating costs. The need for dozens of correspondent accounts (nostro/loro) disappears. A single common ledger replaces a complex web of bilateral relationships.
2. Benefits for corporate clients:
Speed. Transferring dollars from New York to Jakarta will take minutes, not days.
Transparency. Transaction status is visible to all participants in real time.
3. Benefits for the tokenized asset market:
Liquidity. Tokenized bonds issued on a private blockchain will be able to access the global market via a SWIFT gateway.
And now for the obstacles, which are already well known. Successful integration depends not on the technology (it's already proven), but on the "human factor":
1. Global harmonization of rules is needed. The European MiCA (Markets in Crypto-Assets) standard has been taken as a model. But without uniform global rules on a global scale, the SWIFT bridge could hit a legal dead end.
2. In public blockchains, the loss of a private key equals the loss of assets. Institutional transactions require multi-signature systems with strict access control at the corporate security level. 3. Conglomerates (JP Morgan, BNP, HSBC, etc.) are participating in tests, but the "network effect" will only kick in when thousands of smaller banks join the system.
Conclusion
SWIFT isn't just catching up with the crypto industry. It's seizing the initiative, offering a regulated, secure, and, most importantly, interoperable path to the tokenization of finance.
We're on the verge of a situation where, in 5-7 years, the very concept of a "correspondent account" may become a thing of the past. Its place will be taken by a smart contract that automatically executes a bond payment at 3 AM on Sunday, because that's what the program code says.
