Basel I, II, and III are agreements that established regulatory standards for bank capital adequacy. Basel I, established in 1988, focused on credit risk and set minimum capital requirements of 8% of risk-weighted assets. Basel II, released in 2004, included three pillars: Pillar I established a revised minimum capital framework; Pillar II covered supervisory review; and Pillar III addressed market discipline through disclosure. It recommended a minimum ratio of total capital to risk-weighted assets of 8% and prescribed the minimum capital adequacy ratio of 9% for India. Basel III, finalized in 2017, strengthened bank capital requirements in response to the 2008 financial crisis.
