The Depository Trust & Clearing Corporation (DTCC) is set to tokenize 1.4 million securities in its custody, marking a significant step towards digital transformation in U.S. capital markets. DTCC's tokenization platform, developed after acquiring Securrency in 2023, aims to enable digital access to all DTC-eligible securities, including equities, mutual funds, and fixed income products. This initiative will allow investors to convert securities into tokenized formats and back within 15 minutes, facilitating decentralized finance strategies and 24/7 settlement.DTCC's approach includes supporting tokenized cash through stablecoins or deposits and focuses initially on collateral optimization to enhance financing strategies. The company emphasizes interoperability and security, opting to burn and reissue tokens when moving between chains rather than using blockchain bridges. This move is part of DTCC's broader strategy to digitize existing market structures without altering fundamental market dynamics.
