The Imperial Bank of India was a major commercial bank that operated in British India and the early years of independent India. It was established in 1921 through the amalgamation of the three Presidency Banks—the Bank of Bengal, the Bank of Bombay, and the Bank of Madras—and functioned as the largest commercial bank of its time. In 1955 it was nationalised and reconstituted as the State Bank of India under the State Bank of India Act, 1955.

For much of the nineteenth century, modern banking in British India was conducted primarily through the three Presidency Banks, each chartered to operate in one of the presidencies of Bengal, Bombay and Madras. These banks combined commercial banking activities with limited central banking functions on behalf of the colonial government, including the management of public debt and the holding of government balances.
By the early twentieth century, the need for a single, larger institution capable of supporting a more integrated banking system across India was widely recognised. The Imperial Bank of India Act was passed in 1920 to provide the legislative basis for such an amalgamation.
The Imperial Bank of India came into existence on 27 January 1921, bringing together the assets, branches and staff of the three Presidency Banks. It was set up as a joint-stock bank, privately owned by shareholders, and operated under statutory provisions that gave it a special relationship with the Government of India.
Until the establishment of the Reserve Bank of India in 1935, the Imperial Bank performed several quasi-central banking functions. It acted as the banker to the Government of India in places where the government did not maintain its own treasuries, managed the public debt, and held cash balances on behalf of the state. It was, however, also expected to expand commercial banking and to develop branches across the country.
The bank's primary activities included:
Following the establishment of the Reserve Bank of India in April 1935, the central banking functions previously discharged by the Imperial Bank were transferred to the new institution. The Imperial Bank continued thereafter as the country's largest commercial bank and acted as the sole agent of the Reserve Bank at places where the Reserve Bank did not have its own offices.
After independence, policy thinking on banking shifted towards public ownership of major financial institutions, particularly to extend banking to rural and semi-urban areas. The All-India Rural Credit Survey, conducted by the Reserve Bank of India in the early 1950s, recommended the creation of a state-sponsored, state-partnered commercial bank with an extensive branch network.
Acting on these recommendations, Parliament enacted the State Bank of India Act, 1955. Under this Act, the Imperial Bank of India was taken over by the Reserve Bank of India and reconstituted as the State Bank of India, which began operations on 1 July 1955. The branches, staff and business of the Imperial Bank were transferred to the new institution.
The Imperial Bank of India occupies an important place in Indian banking history. It represented the consolidation of nineteenth-century Presidency banking into a single nation-wide institution, served as a transitional central bank in the years before the Reserve Bank, and provided the institutional foundation upon which the State Bank of India—India's largest commercial bank—was subsequently built. Its archives and branch network form a direct line of continuity between colonial-era banking and the modern Indian banking system.
