State Bank of India (SBI) is the largest and one of the oldest public sector banks in India, with a rich history that dates back to the early 19th century. It was established as the Bank of Calcutta in 1806, which later became the Imperial Bank of India before being renamed as the State Bank of India in 1955. Headquartered in Mumbai, SBI operates an extensive network of branches and ATMs across India and has a significant international presence with branches and subsidiaries in numerous countries.

SBI plays a crucial role in the Indian banking sector, providing a wide range of financial products and services, including personal banking, corporate banking, investment banking, and wealth management. It is also a major player in the agricultural and rural banking sector, offering various schemes and loans tailored to the needs of farmers and rural businesses. As a government-owned entity, SBI is often involved in implementing various government financial initiatives and policies aimed at promoting economic development.

SBI's influence extends beyond traditional banking, as it has also ventured into digital banking and fintech, with services like YONO (You Only Need One), a comprehensive digital banking platform. The bank has consistently been a key player in shaping India's financial landscape, contributing to its economic growth and stability.
