美国最大证券存管与清算机构DTCC近期推进基于真实证券资产的代币化试验，意味着区块链技术正在从加密市场的实验场，逐步进入传统金融核心基础设施。DTCC作为美国证券市场的重要清算机构，其探索方向并非发行新的数字资产，而是研究如何让现有证券资产具备链上流转能力。 过去市场讨论的RWA更多集中于小规模资产映射，而金融机构真正关注的是股票、ETF、美债等高流动性资产能否通过数字化方式提升交易效率和抵押效率。 对宏观交易员而言，代币化最大的价值在于降低结算摩擦和释放抵押品效率。如果美债、ETF等高流动性资产未来能够在合规链上流转，金融机构的质押、划转和回购效率有望大幅提升，进一步提高全球金融体系的资金使用效率。
