The Securities and Exchange Commission has shelved a draft rule that would have allowed stock trading through blockchain tokens, following objections from market participants. The proposal, which aimed to permit tokenized versions of traditional equities to trade on alternative platforms, is now on hold indefinitely.
Why the proposal stalled
The SEC’s decision to delay followed a comment period in which exchanges, clearinghouses, and investor groups raised concerns about investor protections and market structure. Tokenized stocks — digital representations of shares issued on a blockchain — would have moved settlement from the standard two-day cycle to near-instantaneous finality. Critics argued that the shift could introduce new risks around custody, fraud, and systemic stability without adequate safeguards.
Regulators had been weighing the change for months as part of a broader push to modernize equity markets. The draft would have allowed so-called “security tokens” to trade on registered exchanges under a streamlined framework, bypassing some legacy requirements. But after industry feedback flagged gaps in the proposal, the SEC pulled it from its formal agenda.
What tokenized stocks would change
Under current rules, stock trades settle through the Depository Trust & Clearing Corporation’s central system, a process that takes two business days. Tokenized shares would instead live on a blockchain, with ownership recorded on a distributed ledger. Proponents say that cuts settlement time and lowers costs. Skeptics warn that the technology is not mature enough for the scale of U.S. equity markets, which handle trillions of dollars in daily volume.
The proposal did not specify which blockchain platforms would qualify, leaving the industry to guess at technical requirements. Several large financial firms had already piloted tokenized stock programs overseas, but the SEC’s green light would have brought them into the domestic regulatory fold.
No new timeline
The SEC has not said when, or if, it will release a revised version of the rule. Agency staff are still reviewing the comments, according to people familiar with the matter. Until the commission reopens the process, tokenized stock trading remains in a legal gray area — allowed in private pilot programs but not for public, exchange-based trading.
