CMB engages in the provision of corporate and personal banking services. It focuses on individual and corporate businesses, credit card, and small and medium enterprises. It operates through three business segments: wholesale finance, retail finance, and other businesses.

In 1987, China Merchants Bank (CMB) was founded in Shekou Industrial Zone of Shenzhen, the forefront of China's reform and opening-up. It is China's first joint-stock commercial bank wholly owned by corporate legal entities and represents the first pilot bank to promote China's banking reform driven by endeavors outside the government.

CMB has over five hundred branches in mainland China and one in Hong Kong. In November 2007, as part of a drive for international growth, it won federal approval to open a branch in New York City.

By the end of 2019, with over 80,000 employees, CMB has set up a service network that consists of more than 1,800 branches worldwide including six overseas branches, two overseas representative offices, and service outlets located in more than 130 cities of mainland China.

In the 2022 Forbes Global 2000, CMB was ranked as the 24^th largest public company in the world.
