SEC unveils tokenized securities modernization plans

TLDR

The US Securities and Exchange Commission is rolling out a modernization agenda that explicitly includes tokenized securities and updated market plumbing for onchain assets.

1. The SECs Trading and Markets division outlined initiatives around tokenized securities, custody, and 24/7 markets, building on pilots like the DTCC tokenization program.
2. These plans could lower legal and operational risk for tokenized Treasuries, ETFs, and stocks, making it easier for brokers, custodians, and even DeFi projects to handle regulated onchain securities.
3. The next signals will come from specific SEC rulemakings, DTCC and ETF tokenization approvals, and a joint SECCFTC harmonization event that may clarify how tokenized assets are supervised.

Deep Dive

1. What The SEC Just Signaled

At the STAC Conference on 22 Jan, Jamie Selway, head of the SECs Division of Trading and Markets, outlined new initiatives focused on tokenized securities and market modernization, aimed at primary issuance, secondary trading, and custody of tokenized instruments on regulated infrastructure. His remarks framed the approach as innovation without arbitrage, meaning the SEC wants new technology but not regulatory loopholes that let tokenized products sidestep existing protections.

Selway highlighted structural work such as a Depository Trust Company (DTC) pilot for custody solutions that could reshape trading frameworks and give broker?dealers more confidence around tokenized securities. This sits on top of the SECs prior no?action relief for DTCC to run a tokenization program covering US Treasuries, ETFs and large?cap equities, where tokenized positions keep the same legal rights and investor protections as traditional shares.

2. Why Tokenized Securities Matter For Crypto Users

Regulated tokenization is already moving: DTCC has a tokenization program scheduled to launch on approved blockchains in late 2026, and asset manager F/m Investments has asked the SEC to let it tokenize shares of its 3?month US Treasury ETF so ownership can be recorded on a permissioned chain while remaining a standard 1940 Act fund.

These efforts, combined with exchange plans like the New York Stock Exchange exploring 24/7 trading and onchain settlement of tokenized stocks and ETFs, point to tokenization of Treasuries, funds and equities as a core bridge between traditional finance and public chains. For crypto users, that increases the likelihood that things like tokenized T?bills or stock baskets become widely available, potentially usable as collateral in DeFi, but with full securities?law constraints attached.

3. What To Watch Next

First, watch for concrete SEC outputs: proposed rules or guidance on broker?dealer custody of tokenized securities, alternative trading systems (ATS) rules that explicitly mention onchain settlement, and any public expansion of the DTC or DTCC pilots beyond limited asset sets.

Second, the SEC and CFTC have scheduled a joint event on harmonization and US financial leadership in the crypto era, where tokenized assets are expected to feature among topics. That session, alongside market structure bills in Congress, could clarify which agency oversees which parts of tokenized markets.

Third, approvals for specific products, such as F/ms tokenized Treasury ETF or future tokenized equity funds, will show whether the SEC is willing to let fully onchain recordkeeping coexist with mainstream distribution via brokers and exchanges.

Conclusion

The SECs modernization push treats tokenization as an upgrade to securities infrastructure rather than a separate crypto wild west. If pilots and rule changes move forward, regulated tokenized Treasuries, ETFs and equities could become standard building blocks on and across public chains. For crypto participants, the edge will come from tracking where regulated onchain assets gain real depth and utility, while respecting that they remain firmly inside the securities perimeter.
