Basel I: The Initial Basel Accord on Credit Risk

Basel I focuses primarily on credit risk management, establishing the first set of international banking regulations to ensure financial stability and minimize risks in the banking sector.

Basel I refers to the first Basel Accord, formulated by the Basel Committee on Banking Supervision (BCBS) in 1988. Its primary objective is to enhance the stability of the international banking system by establishing standardized regulations focused on credit risk.

Objectives of Basel I

To ensure a level playing field among international banks and reduce the risk of financial crises, Basel I introduced the concept of minimum capital requirements, strengthening the resilience of banks in the face of financial challenges.

Key Components of Basel I

Credit Risk

Credit risk is the risk of loss due to a borrower’s failure to make payments as agreed. Basel I brought a standardized approach to measuring credit risk, which banks must uphold to maintain solvency and protect depositors.

Capital Adequacy Ratio (CAR)

Basel I introduced the Capital Adequacy Ratio (CAR), calculated as follows:

$$ \text{CAR} = \frac{\text{Tier 1 Capital} + \text{Tier 2 Capital}}{\text{Risk-Weighted Assets}} $$

Where:

• Tier 1 Capital: Core capital including equity capital and disclosed reserves.
• Tier 2 Capital: Supplementary capital such as revaluation reserves and undisclosed reserves.
• Risk-Weighted Assets (RWA): The sum of assets weighted based on their risk level.

Banks were required to maintain a minimum CAR of 8%.

Risk Weighting

Basel I assigned different risk weights to various asset classes:

• 0% for risk-free assets like cash and sovereign debt from OECD countries.
• 20% for claims on banks from OECD countries.
• 50% for mortgage loans.
• 100% for commercial loans and consumer credit.

Implementation and Impact

Basel I was implemented in member countries in the early 1990s, achieving its goal of harmonizing international bank standards and making banks more resilient to financial shocks.

Historical Context

Established by the BCBS, the Basel Committee consists of central bankers and regulators from major economies. Basel I laid the foundation for subsequent accords, namely Basel II and Basel III, which progressively introduced more sophisticated frameworks addressing a broader range of risks, including market and operational risks.

Comparative Overview

Basel I vs. Basel II

While Basel I focused mainly on credit risk, Basel II expanded to include market and operational risks with a more complex framework, introducing the three-pillar approach:

1. Minimum Capital Requirements.
2. Supervisory Review Process.
3. Market Discipline.

Basel I vs. Basel III

Basel III, developed in response to the 2008 financial crisis, significantly strengthened regulatory standards with higher and more resilient capital buffers, liquidity requirements, and leverage ratios.

FAQs

What is the main focus of Basel I?

Basel I primarily focuses on credit risk by standardizing the measurement of capital adequacy, emphasizing the importance of maintaining a minimum CAR of 8%.

How does Basel I categorize asset risk?

Basel I assigns risk weights to assets, ranging from 0% for low-risk assets to 100% for high-risk assets like commercial loans.
