Indian banking sector has undergone a thorough change and remarkable transformation during the last two decades. The banking reforms implemented on the basis of the blue print provided by Narasimham Committee and other wide ranging supportive measures initiated and implemented by Government of India and RBI have contributed significantly to the enhancement of financial strength, intrinsic soundness, resilience and operational efficiency of banks. Banks in India have been showing stronger balance sheet footing with better asset quality in post reform period. The post-reform period has also witnessed advent of new players, product innovations and introduction of new instruments and new approaches to aggressive marketing of such new products. Banks presently operate in an increasingly deregulated and market driven competition of operational flexibility. State Bank of India leads the public sector pack, emerging as third in the overall banking and finance. State Bank of India is the largest bank in the country and has witnessed a great transformation in recent years. It has given private sector banks the run for their banks. Thanks to the adoption of state-of-the art banking technologies and introduction of best banking services on the technology front, State Bank of India is working on the linking of branch operations in under way as well as on new solutions for treasury business and risk management. In this paper, an attempt has been made to study the financial performance of State Bank of India. In view of this, the study is focused on deposit and advance; credit deployment; Gross NPAs and Net NPAs; Profitability; and Productivity of SBI during the period from 2007-08 to 2012-13.
