NextFin News - On December 11, 2025, the U.S. Securities and Exchange Commission (SEC) granted official authorization for the Depository Trust & Clearing Corporation (DTCC) to utilize blockchain technology for recording stock ownership. This authorization, announced in Washington, D.C., formalizes DTCC's pathway to integrate distributed ledger technology (DLT) into the centralized infrastructure that underpins U.S. securities settlement systems. The decision emerges amid President Donald Trump's administration efforts to modernize financial market infrastructure and boost the fintech industry's growth.
This regulatory approval empowers DTCC to transition the book-entry recordkeeping of stocks to a blockchain platform, enabling a tamper-proof, transparent, and real-time ledger of ownership and transaction history. The transition aims to replace legacy systems relying heavily on intermediated electronic databases. The SEC emphasized that this move addresses longstanding market inefficiencies, reduces counterparty risk, and aligns with global trends toward tokenization and digital asset frameworks.
The authorization was achieved through a rigorous SEC review process that evaluated custodian security, data integrity, compliance capabilities, and operational resilience of the blockchain solution. DTCC's technology leverages permissioned blockchain infrastructure, ensuring controlled participant access and regulatory oversight, while harnessing cryptographic immutability to prevent fraudulent record alterations.
From a structural perspective, DTCC processes approximately over $1.5 quadrillion worth of securities transactions annually, underlying roughly 97% of U.S. equity trades. Integrating blockchain is projected to streamline post-trade operations by enhancing record synchronization between brokers, clearinghouses, and settlement agents. This adoption reduces reconciliation needs, decreases settlement times from the current T+2 standard closer to near-instant settlement, and lowers systemic settlement risk.
The adoption also promises cost efficiencies. Historically, DTCC's legacy recordkeeping and settlement infrastructure incurred significant maintenance costs estimated at over $100 million annually. Blockchain automation is expected to cut these by up to 30%, benefiting all stakeholders, including custodians, broker-dealers, and end-investors.
Moreover, this initiative is likely to foster innovation in secondary markets, notably enabling more seamless issuance and transfer of digital securities. It strengthens the U.S. capital markets’ competitiveness by aligning regulatory frameworks with technological advances seen in crypto-assets, decentralized finance (DeFi), and tokenized asset ecosystems. DTCC's platform also prepares the infrastructure for potential future regulatory approvals of tokenized stock trading.
Reflecting on causes, this move is driven by persistent demand for operational transparency, regulatory agility, and technological modernization to address past settlement failures (such as the 2020 'market infrastructure bottlenecks') and the growing digital asset economy. It also responds to global competitive pressures as other major financial centers (e.g., London Stock Exchange, Singapore Exchange) have piloted blockchain in clearing and settlement.
The impact extends beyond operational efficiencies. Enhanced transparency can reduce fraud and enhance investor confidence. The immutable ledger characteristic of blockchain ensures a more trustworthy record, deterring tampering and simplifying audit processes for regulators. Furthermore, faster settlement cycles increase capital efficiency, freeing up liquidity for market participants and potentially reducing systemic risk during periods of market stress.
Potential risks include the technology’s early-stage nature and integration complexity with legacy systems. DTCC must ensure robust cyber-security frameworks and mitigate risks related to smart contract vulnerabilities and network outages. Regulatory coordination will be paramount to maintain market stability during this transition.
Looking ahead, this SEC authorization is expected to set a precedent for other clearing agencies globally. It may catalyze broader regulatory acceptance of blockchain-based recordkeeping in other asset classes such as fixed income, derivatives, and mutual funds. As blockchain matures, we may witness parallel evolutions in real-time settlement models and the emergence of programmable securities, where settlement and compliance are embedded in digital contract code.
In summary, the SEC’s approval for DTCC to record stocks using blockchain represents a landmark development in capital markets infrastructure modernization under U.S. President Trump’s administration. By enabling enhanced transparency, security, and efficiency, this initiative lays critical groundwork for the future of digital securities trading and settlement, positioning the U.S. markets to lead the next generation of financial innovation.
