SEC Gives Wall Street a Blockchain Upgrade  

The Securities and Exchange Commission has approved a proposal from Nasdaq that allows certain stocks and exchange-traded funds to be traded in a “tokenized” form, meaning ownership is recorded on a blockchain rather than through traditional bookkeeping systems. It’s a notable moment. For the first time, blockchain technology is being formally woven into the backbone of America’s stock markets.

To understand what this means, a bit of context helps. Last December, the SEC’s staff gave the green light to a pilot program run by the Depository Trust Company, or DTC, the behind-the-scenes organization that keeps track of who owns what on Wall Street. That pilot lets certain DTC members convert their ownership stakes in securities into digital tokens stored in blockchain wallets. Nasdaq’s new rule builds directly on top of that foundation.

According to a recent analysis by global law firm Dechert, the new Nasdaq rules allow eligible market participants “to trade tokenized versions of certain highly liquid equity securities and ETFs on the same order book and with the same execution priority as their traditional counterparts.” In plain English, tokenized shares and regular shares line up in the same trading queue, treated as equals, as long as the tokenized version carries the same rights and the same ticker symbol as the original.

The securities eligible for tokenization include stocks in the Russell 1000 Index as well as ETFs tied to major benchmarks like the S&P 500 and the Nasdaq-100. Participation is optional. Traders who want their orders handled in tokenized form simply select a special flag when placing their order, and Nasdaq passes that preference along to DTC, which does the heavy lifting.

Here’s the catch, though: this isn’t the blockchain revolution some have been waiting for. Settlement still happens on the existing one-day timeline. Speeds do not improve. Crypto enthusiasts who envision instant, round-the-clock trading will find little to celebrate here, at least for now.

Dechert’s analysts noted the tension, writing that “crypto market participants will note that the new rule facilitates settlement on the existing T1 model, thereby offering no real benefit in terms of settlement speed.”

Still, even incremental movement can set important precedents. And the Nasdaq approval appears to be just the beginning. Dechert points out that the New York Stock Exchange has already signaled its intention to build a tokenization platform of its own, one that would potentially allow 24/7 trading, instant settlement, and the ability to fund purchases using stablecoins. Nasdaq itself has made clear it views its current proposal as one approach among many, and that other forms of tokenization and settlement are actively being explored.

The new Nasdaq rule will not take effect immediately. It becomes operational only after DTC finishes building the necessary infrastructure. Nasdaq will give its members at least 30 days’ notice before tokenized trading goes live.

What’s coming next, Dechert suggests, is a broader and faster evolution. Regulators and exchanges are clearly moving in the same direction. The machinery of American finance is slowly, but unmistakably, being rewired.
