BlackRock CEO Larry Fink has proposed a shift in investment strategy, suggesting that the traditional 60/40 portfolio may no longer provide adequate diversification. In his annual letter to investors, Fink recommends a new model comprising 50% stocks, 30% bonds, and 20% private assets such as real estate and infrastructure. Concurrently, the Depository Trust & Clearing Corporation (DTCC) has launched a new platform for tokenized collateral management, leveraging its AppChain technology built on the Hyperledger Besu blockchain. This platform aims to enhance the efficiency and mobility of collateral in institutional decentralized finance (DeFi) applications. The DTCC, which handles approximately $2.5 quadrillion annually, is positioning itself at the forefront of the tokenization trend, which Fink believes will make markets faster and more accessible. The recent approval of BlackRock as a crypto asset firm by the UK's Financial Conduct Authority further underscores the company's commitment to integrating blockchain technology into its operations.
