Prudential Norms and Basel Framework for Banks

Prudential norms are safeguards that help banks remain viable, absorb losses and manage risk. The Basel Framework provides internationally agreed standards for capital, liquidity and supervision, while national regulators adapt these standards to their banking systems.

Prudential Norms in Indian Banking

The Reserve Bank of India (RBI) issues prudential guidelines under the Banking Regulation Act, 1949, and the Reserve Bank of India Act, 1934. They support depositor protection, financial stability and orderly credit growth by requiring banks to maintain adequate capital and liquidity and control their exposures. Key elements include:

• Capital adequacy: Banks must hold capital in proportion to the risks they undertake, enabling them to absorb losses and continue operating.
• Asset classification: Loans and advances are classified as Standard, Sub-standard, Doubtful or Loss assets according to their performance.
• Provisioning: Banks set aside funds against expected losses on assets. Requirements vary by classification, from provisions on standard assets to 100% for loss assets.
• Income recognition: Income from non-performing assets (NPAs) is recognised when received, rather than on an accrual basis.
• Exposure limits: Limits on lending to a single borrower or group help prevent excessive concentration of credit risk.

Together, these requirements influence banks’ lending decisions and loss-absorption capacity. Their effectiveness depends on accurate asset classification, timely provisioning and sound internal risk controls.

The Basel Framework

The Basel Framework is developed by the Basel Committee on Banking Supervision (BCBS), which operates under the Bank for International Settlements (BIS) in Basel, Switzerland. Established in 1974, the BCBS seeks to improve the stability of individual banks and the resilience of the global financial system. The BCBS has no formal supranational authority and does not issue legally binding rules. Its standards are nevertheless widely adopted by member jurisdictions and more than 100 countries. National regulators implement them through domestic laws and rules, adapting requirements to local conditions. The framework’s regulatory approach combines:

• Regulation: Minimum requirements, including capital and liquidity standards.
• Supervisory discretion: Review of banks’ capital adequacy and risk-management processes in light of their overall risk profiles.
• Market discipline: Disclosure requirements that help market participants assess banks’ capital positions and risk exposures.

Basel Accords

The Basel standards have developed in response to gaps in risk measurement and lessons from financial stress. The main stages are:

• Basel I (1988): The first international capital adequacy agreement focused mainly on credit risk. It set a minimum capital-to-risk-weighted-assets ratio (CRAR) of 8%. Capital was divided into Tier 1, including equity and retained earnings, and Tier 2, including supplementary capital such as subordinated debt and revaluation reserves.
• Basel II (published in 2004; implemented in 2007): It made capital requirements more risk-sensitive and introduced three pillars. Pillar 1 covers minimum capital for credit, market and operational risks. Pillar 2 provides for supervisory review of a bank’s overall risk profile and capital adequacy. Pillar 3 uses public disclosures to strengthen market discipline.
• Basel III (developed from 2010): Developed after the 2008 global financial crisis, it strengthened capital quality and quantity, improved liquidity standards and introduced a leverage ratio as a non-risk-based backstop.
• Common Equity Tier 1 (CET1): Basel III places greater emphasis on this highest-quality form of regulatory capital, which is intended to absorb losses while a bank remains a going concern.
• Capital Conservation Buffer (CCB): A 2.5% of risk-weighted assets (RWA) buffer, met with CET1, builds capital in good times for use during stress. Breaching it can restrict dividends, share buybacks and discretionary bonuses.
• Counter-Cyclical Capital Buffer (CCyB): A buffer of up to 2.5% of RWA that national authorities may apply during periods of excessive credit growth to address system-wide risks.
• Liquidity standards: The Liquidity Coverage Ratio (LCR) requires high-quality liquid assets to cover net cash outflows over a 30-day stress period, with a minimum of 100%. The Net Stable Funding Ratio (NSFR) requires stable funding over a one-year horizon and must also be at least 100%.

Implementation in India

The RBI has adopted and adapted Basel standards for Indian banks. Under Basel III, the minimum CRAR is 9%, compared with the global minimum of 8%. The stated minimum CET1 requirement is 5.5%, alongside a CCB of 2.5%. Including the CCB, the effective well-capitalised minimum CRAR is 11.5%. The Prompt Corrective Action (PCA) framework enables supervisory action when a bank falls below specified thresholds, including capital thresholds. It complements minimum capital rules by providing a mechanism to address weaknesses. These requirements are relevant to capital adequacy, risk management and banking resilience: banks need sufficient loss-absorbing capacity without undermining sustainable credit provision.

Key Prelims Takeaways

• RBI prudential norms cover capital, asset classification, provisioning, income recognition and exposure limits.
• The BCBS operates under the BIS and sets standards that countries implement through domestic regulation.
• Basel I set an 8% minimum CRAR and focused mainly on credit risk.
• Basel II established three pillars: minimum capital requirements, supervisory review and market discipline.
• Basel III strengthened capital and liquidity requirements and introduced a leverage ratio.
• India’s Basel III minimum CRAR is 9%; the effective minimum including the CCB is 11.5%.

Recent Context

Constituted on October 30, 2026, following an announcement in the Union Budget 2026–27, the six-month committee is chaired by former Central Vigilance Commissioner Suresh N. Patel. It will recommend reforms covering prudential and legal frameworks, bank capital, digital risks and credit, aiming for a globally competitive, inclusive and resilient banking system by 2047.
