Tokenization is changing the game: the SEC opens the door for digital securities settlement

Settlement of securities is entering a new era. Depository Trust Company has received conditional approval from the SEC to implement a tokenization system for assets already held within its infrastructure. The decision from December 11th signifies a shift in regulatory boundaries—and potentially the end of the traditional three-day settlement period.

The SEC staff's position does not constitute formal approval but rather confirms that the agency will not initiate enforcement actions against DTC within specified parameters. This distinction is crucial for investors observing the digitization of financial markets.

How this changes the existing settlement model

The three-day T+3 cycle (transaction plus three days) has been the foundation of modern capital markets for decades. Tokenization opens the possibility of settlement directly between blockchain wallets, bypassing conventional intermediary pathways.

As part of the pilot, DTC will represent securities rights as tokens stored in registered participant wallets. When a participant opts for tokenization, DTC will debit their entitlement in the accounting system and issue a token directly to the blockchain wallet. Transfers between wallets will become instantaneous.

Key point: securities will remain registered in the name of Cede & Co., the depository institution. DTC will maintain full oversight and visibility—this is not a transfer of ownership in the traditional sense but a change in how rights are represented.

Preliminary phase: restrictions and risk controls

The SEC has approved very conservative start parameters. DTC will begin with shares belonging to the Russell 1000, additionally including bonds, treasury bills, and selected index ETFs. Participation is voluntary—about 89% of DTC participants may join, excluding those awaiting resolution of tax and TIC reporting issues.

Tokens can only move between wallets on the whitelist associated with DTC participants. Transfers to wallets outside the ecosystem are prohibited. DTC will perform OFAC checks and enforce compliance with control standards (e.g., ERC 3643).

A significant restriction: tokenized rights will not have collateral or settlement value for DTC’s internal calculations (Net Debit Cap, Collateral Monitor). Delivery-versus-payment settlement will occur outside the DTC system. This safeguard ensures that the experiment does not threaten the stability of the central market infrastructure.

Implementation timeline: from theory to practice

The journey from concept to full operation spans several phases:

Fall 2025 – proof-of-concept using synthetic assets, testing LedgerScan (off-chain tracking system) and Factory (token issuance system).

Early 2026 – limited live pilots with selected participants, assessing actual transfer flows and detokenization processes.

Second half of 2026 – broad deployment, during which DTC begins offering DTCC Tokenization Services commercially.

Post-launch – the SEC’s position is valid for three years, after which it expires without automatic renewal. DTC will report quarterly on participating firms, number of tokenized shares, blockchain usage, and any failures.

What this means for the future of financial markets

DTCC CEO Frank La Salla described the potential: 24/7 collateral mobility, programmable assets, new trading models. The DTC letter reveals ambitions to extend beyond the initial phase—considering stablecoins, tokenized deposits, and even corporate dividend distributions.

Each extension requires additional consultation with the SEC before crossing current boundaries. It’s not uncharted territory without a map—regulators want quarterly data, blockchain monitoring, and the ability to withdraw.

Market estimates suggest around $68 trillion in potential value in a full tokenization scenario. The SEC’s decision places DTC at the forefront of this transformation, offering the first officially approved bridge between traditional infrastructure and the digital future.

For investors, this means: the day when settlement could take three days is gradually becoming history. The future—at least in American finance—will be instant.
