In 2026, regulatory scrutiny on data security will undergo a substantial escalation. On June 13th, six key regulatory bodies, including the Cyberspace Administration of China and the People's Bank of China, collaboratively unveiled the 'Guidelines for the Classification and Grading of Data in Financial Information Services.' These guidelines are designed to steer financial institutions in systematically categorizing and grading their data, as well as pinpointing critical data assets. As the financial sector continues its profound digital transformation, data has emerged as a pivotal element underpinning the banking industry's growth trajectory. Effective data classification and grading serve as the cornerstone for fortifying data security measures. An expert from the data management division of a city commercial bank emphasized that, to harness the full potential of data, ensuring robust data security is paramount and cannot be sidelined.
