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.

420% growth in tokenized RWA since jan 2025 is insane. nasdaq filing the 19b-4 is the real signal though, this is wall street building onchain not just talking about it
swift adding a blockchain shared ledger is the quietest big news here. they process trillions daily, even a fraction onchain changes everything
Nine European banks including ING and UniCredit launching a joint euro stablecoin under MiCAR is huge for EU markets. Finally some competition for USDC in the eurozone.
