Largest Banks, Exchanges and Financial Institutions in India

The Indian banking architecture is divided into scheduled commercial banks—categorized into public sector banks (PSBs), private sector banks, and foreign entities—under the statutory regulation of the Reserve Bank of India (RBI) via the Banking Regulation Act, 1949.

Domestic Systemically Important Banks (D-SIBs)

The RBI classifies specific banking institutions as Domestic Systemically Important Banks (D-SIBs), colloquially referred to as “Too Big to Fail.” This framework requires these banks to maintain higher Tiers of Common Equity Tier 1 (CET1) capital as a percentage of Risk-Weighted Assets (RWAs). The current designated D-SIBs are:

• State Bank of India (SBI) – Positioned in Bucket 4, requiring an additional CET1 requirement of 0.80%.
• HDFC Bank – Positioned in Bucket 3, requiring an additional CET1 requirement of 0.40%.
• ICICI Bank – Positioned in Bucket 1, requiring an additional CET1 requirement of 0.20%.

• Market Footprint: Accounts for approximately 23% of the total domestic credit market share and manages a network of over 22,500 branches.

HDFC Bank (Private Sector Leader)

Incorporated in 1994 and headquartered in Mumbai, HDFC Bank stands as India’s largest private sector bank by total assets and market capitalization.
