In recent years, the rapid advancement of emerging technologies such as big data, blockchain, and artificial intelligence has accelerated the transformation of currencies, shifting from materialization towards digitization and electronization. The e-CNY stands out as a prime example of China’s pioneering digital financial innovation globally. Governed by the central bank, it embodies the national agenda. As the e-CNY’s application field and reach expand, its relationship with the financial market grows increasingly intimate. As a significant participant in China’s financial landscape and a proactive responder to national policies, the securities industry is profoundly influenced by the e-CNY across various domains. Therefore, this paper undertakes a theoretical analysis of the e-CNY’s implementation within securities institutions, concluding that it will usher in a new paradigm for the entire financial system.
