The bank was established as Nadar Bank Limited in the port town of Thoothukudi in southern Tamil Nadu, founded by members of the Nadar mercantile community to support trade and small business finance in the region. It was later renamed Tamilnad Mercantile Bank Limited to reflect a broader customer base beyond a single community.
While the bank's network is concentrated in Tamil Nadu, where it has a dense branch presence in commercial districts, towns and rural areas, it also operates branches across other Indian states. Its business is traditionally weighted towards retail deposits, gold loans, agricultural finance, and lending to micro, small and medium enterprises (MSMEs).
The bank's early decades were marked by steady regional growth as a community-rooted commercial bank. After being renamed Tamilnad Mercantile Bank, it gradually expanded its branch network outside Tamil Nadu and modernised its operations with core banking, ATM services, internet banking and mobile banking.
For several years, the ownership and shareholding of the bank were the subject of long-running legal disputes, which delayed plans for an initial public offering. The bank eventually launched a public issue and became listed on Indian stock exchanges, broadening its shareholder base.
