The Oriental Bank of Commerce (OBC) held a significant position in India's banking sector until its merger with Punjab National Bank (PNB) in 2020. Founded in Lahore in 1943 by Rai Bahadur Lala Sohan Lal, OBC displayed remarkable growth despite facing numerous challenges like the partition of India. Post-partition, its operations were moved to Amritsar, establishing itself as a fundamental part of India's banking system following independence.

Over the years, OBC became notable for its extensive range of financial services, covering asset management, commercial banking, and investment banking. Under the leadership of Mukesh Kumar Jain, as MD & CEO, OBC achieved substantial revenues and built a widespread network of branches and ATMs across India. The bank was recognized for initiating innovative banking programs such as the 'Comprehensive Village Development Programme' launched on Baisakhi in 1997, which aimed at comprehensive rural development.

The 2020 merger marked a major milestone, integrating OBC with PNB and United Bank of India, thereby establishing PNB as India's second-largest public sector bank. This strategic merger was designed to strengthen the banking sector's resilience and efficiency, aligning with the government's broader objectives to enhance banking institutions for an improved customer experience.

OBC's legacy is characterized by its unwavering commitment to serving the needs of the underserved and its significant contributions to India's financial and economic sectors. This history not only showcases the success of a banking institution but also reflects the dynamic changes within India's banking industry over time.
