Basel I Capital Norms

The Basel I Capital Norms represent the first internationally coordinated attempt to standardise bank capital adequacy requirements with the objective of strengthening the stability of the global banking system. Introduced by the Basel Committee on Banking Supervision under the aegis of the Bank for International Settlements, Basel I laid the foundation for risk-based regulation of banks. Its adoption had significant implications for banking systems worldwide, including those in emerging economies such as India, where it influenced regulatory reforms, financial stability, and credit expansion.

Background and Evolution of Basel I

Basel I was finalised in 1988 in response to concerns about the declining capital levels of major international banks and the resulting risks to the global financial system. Before its introduction, capital standards varied widely across countries, creating regulatory arbitrage and competitive imbalances. Basel I sought to establish a common minimum capital framework to ensure that banks maintained adequate buffers against credit risk.
The framework primarily focused on credit risk arising from on-balance-sheet assets such as loans and investments. It prescribed a uniform approach that was relatively simple and easy to implement, making it particularly suitable for countries with developing regulatory infrastructures. Although it did not address market risk or operational risk in depth, Basel I was a crucial starting point for international banking regulation.

Core Features of Basel I Capital Norms

The central requirement under Basel I was the maintenance of a minimum Capital Adequacy Ratio (CAR) of 8 per cent of risk-weighted assets (RWAs). Capital was categorised into two broad tiers:

• Tier I Capital (Core Capital): This included paid-up equity capital and disclosed reserves, representing the most reliable and permanent form of capital.
• Tier II Capital (Supplementary Capital): This comprised items such as revaluation reserves, general provisions, hybrid instruments, and subordinated debt.

Risk-weighted assets were calculated by assigning different risk weights to various categories of assets based on their perceived credit risk. For example:

• Cash and government securities typically carried a 0 per cent risk weight.
• Loans to banks and public sector entities attracted lower risk weights.
• Commercial loans to the private sector generally carried a 100 per cent risk weight.

This risk-weighting mechanism linked capital requirements directly to the risk profile of banks’ asset portfolios.

Basel I and the Global Banking System

At the global level, Basel I improved transparency and comparability of bank capital across jurisdictions. It encouraged banks to strengthen their balance sheets and promoted confidence among depositors and investors. The framework also facilitated cross-border banking operations by reducing disparities in regulatory standards.
However, Basel I was criticised for its simplicity. The broad risk categories did not adequately differentiate between borrowers of varying credit quality, leading to potential mispricing of risk. Banks were incentivised to shift towards higher-risk assets within the same risk-weight category, a phenomenon known as regulatory capital arbitrage. Despite these limitations, Basel I was widely adopted and served as the basis for subsequent reforms.

Adoption of Basel I in the Indian Banking System

In India, Basel I was implemented by the Reserve Bank of India (RBI) as part of a broader programme of financial sector reforms initiated in the early 1990s. These reforms followed the recommendations of the Narasimham Committee and were aimed at enhancing efficiency, competition, and stability in the banking system.
The RBI adopted Basel I norms in a phased manner, making them applicable to all scheduled commercial banks, including public sector banks, private sector banks, and foreign banks operating in India. Indian banks were required to achieve the minimum CAR of 8 per cent, although the RBI eventually mandated a higher ratio of 9 per cent to provide an additional safety margin.

Impact on Indian Banks and Financial Discipline

The introduction of Basel I norms marked a significant shift in the regulatory environment of Indian banking. Prior to this, banks operated under administered interest rates and directed credit programmes, with limited emphasis on capital efficiency. Basel I compelled banks to align their growth strategies with capital availability.
Key impacts included:

• Strengthening of Capital Base: Public sector banks received capital infusions from the government to meet the new norms, while private banks raised capital from the market.
• Improved Risk Awareness: Banks began to assess credit exposure more systematically, leading to better credit appraisal and monitoring practices.
• Balance Sheet Restructuring: There was a gradual shift towards lower-risk assets, particularly government securities, to optimise capital usage.

These changes contributed to improved financial discipline and greater resilience of Indian banks.

Implications for Credit Growth and the Indian Economy

Basel I norms had both positive and constraining effects on credit expansion in India. On the positive side, stronger capital adequacy enhanced depositor confidence and reduced the likelihood of bank failures, supporting overall financial stability. A sound banking system was essential for mobilising savings and channelling them into productive investment, thereby supporting economic growth.
On the other hand, the capital requirements imposed constraints on rapid credit expansion, particularly for sectors perceived as high-risk. Small and medium enterprises and infrastructure projects, which often required large exposures, faced tighter credit conditions. This highlighted the trade-off between prudential regulation and developmental objectives in a developing economy like India.

Limitations and Criticism in the Indian Context

While Basel I was a milestone, its limitations were evident in the Indian context. The standardised risk weights did not adequately reflect the actual credit risk of borrowers in diverse sectors of the economy. The heavy reliance on government securities with zero risk weight also encouraged banks to invest excessively in sovereign debt, potentially crowding out private investment.
Moreover, Basel I did not address non-performing assets comprehensively, a major issue for Indian banks during the 1990s. The framework’s narrow focus on credit risk meant that other emerging risks were insufficiently captured.

Transition to Advanced Basel Frameworks

Despite its shortcomings, Basel I played a crucial role in preparing Indian banks for more sophisticated regulatory regimes. It laid the groundwork for the subsequent adoption of Basel II and Basel III, which introduced more risk-sensitive approaches, capital conservation buffers, and liquidity standards.
The experience gained under Basel I helped Indian regulators and banks develop the institutional capacity, data systems, and risk management practices necessary for these advanced frameworks. As a result, the Indian banking system entered the global financial crisis of 2008 with relatively strong capital positions.
