State Bank of India is the largest banking and financial services company in India by revenue, assets and market capitalisation. It is a state-owned corporation with its headquarters in Mumbai, Maharashtra. As of March 2011, it had assets of US$370 billion with over 13,577 outlets including 157 overseas branches and agents globally. The bank traces its ancestry to British India, through the Imperial Bank of India, to the founding in 1806 of the Bank of Calcutta, making it the oldest commercial bank in the Indian Subcontinent. Bank of Madras merged into the other two presidency banks—Bank of Calcutta and Bank of Bombay—to form the Imperial Bank of India, which in turn became the State Bank of India. The Government of India nationalised the Imperial Bank of India in 1955, with the Reserve Bank of India taking a 60% stake, and renamed it the State Bank of India. In 2008, the government took over the stake held by the Reserve Bank of India. SBI is ranked No. 292 globally in Fortune Global 500 list in 2011.
