The Bank of Madras merged into the other two "presidency banks" in British India, the Bank of Calcutta and the Bank of Bombay, to form the Imperial Bank of India, which in turn became the State Bank of India in 1955. The Government of India took control of the Imperial Bank of India in 1955, with Reserve Bank of India (India's central bank) taking a 60 % stake, renaming it the State Bank of India. In 2008, the government took over the stake held by the Reserve Bank of India.
