FINRA approval unlocks custody for security tokens

TLDR

FINRA has approved Securitize Markets to custody security tokens inside its broker dealer, creating the first fully regulated US stack for tokenized securities.

1. FINRAs expanded approval lets Securitize custody, settle, underwrite, and distribute tokenized securities within a single regulated broker dealer.
2. This closes a critical infrastructure gap for security tokens, enabling on chain IPOs, atomic settlement against stablecoins, and more institutional grade tokenization of real world assets.
3. Next steps to watch include copycat applications by other broker dealers and DTCCs tokenization pilot, which together could pull more traditional assets onto blockchains.

Deep Dive

1. What FINRA Actually Approved

FINRA granted Securitize Markets, a US broker dealer, expanded permission to custody, settle, underwrite, and distribute tokenized securities after a Continuing Membership Application review. Reports describe Securitize as the first broker dealer explicitly allowed to hold tokenized securities directly for clients inside a standard broker dealer entity, not a separate special purpose custodian. This approval also lets Securitize underwrite and participate in tokenized IPOs and secondary offerings, effectively giving it investment bank like capabilities for blockchain based securities.

Securitize itself calls custody inside the broker dealer a foundational unlock for atomic settlement and on chain clearing between tokenized securities and stablecoins within its ATS, replacing multiple intermediaries with a single regulated stack. These capabilities are detailed in coverage of FINRAs decision and Securitizes own comments in recent approval reports.

2. Why Custody Is A Big Unlock

Before this decision, US broker dealers generally could not directly custody security tokens, which forced issuers and investors to rely on fragmented setups with separate custodians and off chain books. The new approval allows Securitize to keep tokenized securities, investor records, and on chain settlement together, enabling features like atomic swaps between tokenized stocks and stablecoins and one transaction settlement flows, as highlighted in custody focused coverage.

For issuers, this means they can run tokenized equity or debt offerings while staying entirely inside a familiar broker dealer framework, with KYC, AML and securities law compliance built in. For investors, it increases comfort that security tokens are held by a regulated entity, with standard protections and clearer recourse than many earlier tokenization experiments.

3. What To Watch Next

This approval does not change rules for the entire market, but it creates a blueprint other broker dealers can now try to follow through the same FINRA process. In parallel, the Depository Trust & Clearing Corporation is preparing a tokenized securities pilot, with limited live trades planned before a broader launch that will cover assets already held in DTC custody, including major equities, ETFs and Treasuries, as described in DTCCs tokenization service plans.

If more broker dealers secure similar approvals and DTCCs platform goes live at scale, tokenized securities could move from niche projects to a standard option for traditional issuers. Key open questions are how quickly other firms apply, which blockchains they support, and whether regulators remain comfortable as volumes grow.

Conclusion

FINRAs approval for Securitize to custody and underwrite security tokens inside a regulated broker dealer removes one of the biggest practical blockers for institutional grade tokenization. Combined with infrastructure moves from core market utilities like DTCC, it points toward a future where stocks, bonds, and other real world assets can live natively on blockchains while still fitting inside existing securities law and custody frameworks.
