The Securities and Exchange Commission is preparing a plan for trading tokenized stocks as soon as this week, a move that could reshape how shares change hands. The proposal would allow stocks to be represented on a blockchain, opening the door to round-the-clock markets and near-instant settlements. But the SEC is also weighing risks — market fragmentation and custody challenges among them — that could slow adoption.
What tokenized stocks would change
Tokenized stocks are digital representations of traditional shares, recorded on a distributed ledger. If the SEC gives the green light, investors could trade these tokens at any hour, not just during standard exchange hours. Settlements — the time between trade and final transfer — could shrink from two days to seconds. That's a big shift for a system that still relies on T+2 in most markets.
The SEC hasn't detailed the exact framework yet. But the plan reportedly covers how tokenized stocks would be issued, traded, and cleared. The agency is said to be coordinating with market infrastructure firms and potential issuers to ensure the system doesn't create new points of failure.
Benefits on the table
Supporters point to efficiency gains. A 24/7 market means investors can react to news at any hour without waiting for the next opening bell. Faster settlement reduces counterparty risk — the chance that one side fails to deliver cash or shares. For retail traders, that could mean quicker access to funds after a sale.
Lower costs are another potential upside. Blockchain-based settlement can cut out middlemen like clearinghouses, though the SEC would still require some form of central oversight. The agency hasn't said whether it would mandate a single settlement system or allow multiple providers.
Risks the SEC is watching
The biggest concern is market fragmentation. If tokenized stocks trade on multiple blockchains or venues, liquidity could split, making it harder to get good prices. Regulators worry that investors — especially retail ones — might end up with worse execution if orders don't find the best available price across all platforms.
Custody is another headache. Traditional shares sit in a broker's account at a clearinghouse. Tokenized shares exist on a blockchain, meaning a lost private key could wipe out an investor's position. The SEC is reviewing how to apply custody rules — which require client assets to be segregated and properly safeguarded — to digital tokens. Firms that hold these assets would need to meet capital and insurance requirements, but the details are still being worked out.
The SEC is also looking at whether existing anti-fraud and market manipulation rules cover trading on decentralized networks. Blockchains are public, but bad actors can still spoof orders or pump tokens. The agency hasn't proposed new rules for that yet, but the plan may include guidance on surveillance and enforcement.
What comes next
The SEC is expected to release the plan later this week. It will then enter a public comment period — likely 30 to 60 days — before any final rulemaking. Market participants are already weighing in: exchanges are offering to host tokenized listings, custodians are positioning to hold the keys, and blockchain firms are building the rails.
One unresolved question is whether the SEC will require tokenized stocks to trade only on registered exchanges or allow peer-to-peer transfers. The answer will determine how much the market changes — and who profits from the shift. For now, the clock is ticking until the agency puts its vision in writing.
