September 2025 emerges as a defining month for blockchain adoption in traditional finance, with Nasdaq filing rule changes to enable tokenized securities trading and nine major European banks announcing plans for a joint euro-backed stablecoin, signaling that the world’s largest financial institutions are no longer experimenting with blockchain — they are building on it.
The developments, both unfolding in September 2025, represent a fundamental shift in how established financial infrastructure views distributed ledger technology. What was once dismissed as a niche technology for cryptocurrency enthusiasts is now becoming the backbone of the next generation of global financial markets.
TL;DR
- Nasdaq filed a Form 19b-4 with the SEC proposing rule changes to allow trading of tokenized equity securities and exchange-traded products
- Nine major European banks including ING, UniCredit, and SEB announced plans for a MiCAR-compliant euro stablecoin
- The tokenized real-world asset market has grown over 420% since the start of 2025
- Swift announced plans to add a blockchain-based shared ledger to its infrastructure
- Tether revealed plans for a US-regulated stablecoin (USAT) with Anchorage Digital as regulated issuer
Nasdaq’s Tokenization Gambit
On September 8, 2025, the Nasdaq Stock Market LLC filed a proposed rule change with the Securities and Exchange Commission under Form 19b-4 (SR-NASDAQ-2025-072) that could reshape how equities trade in the United States. The proposal would enable the trading of equity securities and exchange-traded products in “tokenized form” on Nasdaq’s platform, with settlement occurring through the Depository Trust & Clearing Corporation (DTCC) in token form.
This is not a pilot program or a sandbox experiment. Nasdaq is proposing to integrate blockchain-based settlement directly into one of the world’s largest stock exchanges. All existing exchange routing strategies would be available for orders in tokenized securities, and tokenized securities would participate in all market mechanisms currently available to traditional equities. The filing represents years of behind-the-scenes work and signals that Wall Street’s premier exchange operator believes tokenization is ready for prime time.
Nine European Banks Unite for Euro Stablecoin
Across the Atlantic, the institutional blockchain movement is gathering equal momentum. Nine major European banks — ING, UniCredit, SEB, CaixaBank, KBC, Danske Bank, DekaBank, Banca Sella, and Raiffeisen — announced the formation of a new entity in the Netherlands to issue a MiCAR-compliant euro stablecoin. The consortium is seeking e-money licensing and supervision from the Dutch Central Bank, with the stablecoin expected to launch in the second half of 2026.
The project aims to offer near-instant, programmable payments and settlements, supporting cross-border remittances and supply chain finance. Unlike existing stablecoins that operate largely outside traditional banking oversight, this euro stablecoin would be fully regulated under the EU’s Markets in Crypto-Assets Regulation (MiCA), providing institutional-grade compliance and reliability.
The Tokenized RWA Boom
The timing of these announcements is no coincidence. The tokenized real-world asset market has exploded, growing more than 420% since the start of 2025 on the back of regulatory clarity and institutional demand. Tokenized money market funds are gaining traction in Asia, with Ripple’s RLUSD stablecoin and Circle’s USDC and EURC products expanding their global footprint through partnerships with major exchanges like Kraken.
Tether, the world’s largest stablecoin issuer, has also entered the regulated arena. The company announced its upcoming US-regulated stablecoin (USAT), with Anchorage Digital serving as the regulated issuer and Cantor Fitzgerald as reserve manager. The product launch is anticipated before year-end, pending federal approvals — a move that would bring the largest stablecoin by market capitalization under formal US regulatory oversight for the first time.
Swift Joins the Blockchain Revolution
Perhaps the most significant signal of blockchain’s mainstream arrival came at the end of September, when Swift — the global financial messaging network connecting over 11,000 institutions in 200 countries — announced it will add a blockchain-based shared ledger to its technology infrastructure. Swift described the move as “a pivotal step for global finance” that promises to make instant, always-on cross-border transactions possible at unprecedented scale.
When the infrastructure that underpins the entire international banking system begins integrating blockchain technology directly, the debate about whether distributed ledgers have a place in mainstream finance is effectively over. The question now is not if, but how quickly tokenized assets will become the standard for global financial settlement.
Why This Matters
The convergence of Nasdaq’s tokenization filing, the European banking consortium’s stablecoin project, Swift’s blockchain integration, and the explosive growth of the tokenized RWA market represents an inflection point for blockchain technology. These are not crypto-native startups or blockchain evangelists — they are the world’s largest and most conservative financial institutions making multi-billion-dollar bets on distributed ledger technology. For anyone who has followed blockchain’s journey from Bitcoin whitepaper to Wall Street infrastructure, September 2025 marks the moment the technology graduated from disruptive experiment to institutional imperative. The infrastructure being built today will define how financial markets operate for decades to come.

tokenized_eq_ 18 months is generous. the spot bitcoin ETF took over a decade. nasdaq filing is step one of a very long staircase
420% growth in tokenized RWAs since jan 2025 is the number that matters here. everything else is noise
420% RWA growth is real but tomasz is right that swift adding a shared ledger is the sleeper story. swift handles $5T+ daily, even 1% onchain is massive
Tomasz W. swift doing 5T a day and even 1 percent going onchain would be 50 billion in daily settlement. thats bigger than every DeFi protocol combined
swift adding a shared ledger too? the tradfi rail itself is getting rebuilt and nobody seems to care
swift adding a blockchain shared ledger to its infrastructure is the quietest massive news in this article
swift_obs swift adding a blockchain shared ledger is the quietest massive news in crypto. the backbone of global payments is literally rebuilding itself on chain
Nasdaq filed 19b-4 for tokenized equities and everyone celebrates. SEC approval timeline is 18 months minimum. thats a lifetime in crypto
Swift adding a shared blockchain ledger is the quietest massive news here. they handle 5 trillion daily. even 1 percent onchain changes everything
420% growth in tokenized RWA since Jan 2025 and people still call crypto a casino. Nasdaq filing a 19b-4 is the real institutional door opening

swift adding a shared blockchain ledger got almost zero coverage compared to the nasdaq filing. swift moves $5T daily, thats the bigger story imo
Hiroshi M. swift doing 5T daily and even fraction going onchain changes everything. nasdaq 19b-4 is flashy but swift shared ledger is the actual plumbing upgrade
Hiroshi M. Swift doing 5T daily and adding a shared blockchain ledger got maybe 2 paragraphs of coverage. Nasdaq filing a form got 50 headlines. media has no perspective
nine EU banks launching a joint euro stablecoin while the US Congress cant pass a stablecoin bill is peak regulatory arbitrage. Europe is 3 laps ahead
