This document summarizes the transformation of State Bank of India (SBI) from a state-owned bank to a modernized banking leader. It discusses how SBI was nationalized in 1969 and grew to over 60,000 branches by the 1990s. However, financial reforms in the early 1990s led to losses for the first time. SBI underwent restructuring in the 1970s and 1980s and established subsidiaries. In the 2000s, Chairman O.P. Bhatt led the 'Parivartan' initiative to make SBI customer-oriented, technology-focused, and improve employee attitude through communication. This helped SBI improve its market position, customer satisfaction, and win numerous awards.
