Basel Norms: Basel I, II and III

Basel Norms are international banking standards developed by the Basel Committee on Banking Supervision (BCBS). They provide a common framework for banks to maintain adequate capital, manage risks and remain financially stable.

In simple terms, these norms ensure that banks have enough financial strength to absorb losses and continue operating during difficult times.

What is the Basel Committee on Banking Supervision?

The Basel Committee on Banking Supervision (BCBS) is the main international body that develops prudential standards for banks.

• It was established in 1974 by the central bank governors of the Group of Ten countries.
• It is headquartered at the Bank for International Settlements (BIS) in Basel, Switzerland.
• It provides a platform for banking regulators and central banks to cooperate on supervisory issues.
• Its broader aim is to improve the quality of banking supervision and global financial stability.

Why are Basel Norms Needed?

Banks lend money to individuals, businesses and other entities, using deposits and other sources of funds. Since borrowers may fail to repay, banks are exposed to different types of risks.

Basel norms help address this risk by requiring banks to maintain adequate capital in relation to the risks they take.

The basic idea is simple: a bank taking greater risks should have a stronger financial cushion to absorb potential losses.

Why are They Called Basel Norms?

The norms are named after Basel, the Swiss city where the BIS is headquartered and where the Basel Committee operates.

Basel I, Basel II and Basel III

The Basel Committee has developed three major frameworks: Basel I, Basel II and Basel III.

Basel I

Introduced in 1988, Basel I mainly focused on credit risk—the risk that a borrower may fail to repay a loan.

Its major features included:

• Establishing a framework for bank capital.
• Assigning different risk weights to different assets.
• Prescribing a minimum capital requirement of 8% of Risk-Weighted Assets (RWA).
• India adopted Basel I guidelines in 1999.

Risk-Weighted Assets (RWA) reflect the different levels of risk associated with bank assets. A secured loan, for example, may carry a lower risk weight than an unsecured loan.

Basel II

Basel II was published in 2004 and expanded the approach of Basel I.

It was built around three pillars:

1 – Minimum Capital Requirements
Banks must maintain adequate capital against major risks, including credit, market and operational risks.

2 – Supervisory Review
Banking regulators assess whether banks have adequate capital and effective systems for managing risks.

3 – Market Discipline
Banks are expected to make greater disclosures about their capital, risks and financial position, allowing markets and depositors to better assess their soundness.

Basel III

Basel III was developed after the 2008 global financial crisis. The crisis showed that many banks had insufficient capital, excessive leverage and an overdependence on short-term funding.

Basel III therefore strengthened the banking framework by focusing on:

• Capital
• Leverage
• Liquidity
• Stable funding

Its overall aim is to make banks more capable of withstanding financial shocks.

Key Features of Basel III

Stronger Capital Requirements

Basel III places greater emphasis on the quality and quantity of bank capital. It also provides for capital buffers that can help banks absorb losses during periods of financial stress.

Important components include:

• Tier 1 capital
• Tier 2 capital
• Capital Conservation Buffer
• Countercyclical Capital Buffer

Leverage Ratio

The leverage ratio acts as an additional safeguard against excessive borrowing. It limits how much a bank can expand its balance sheet relative to its core capital.

Liquidity Requirements

Basel III introduced two important liquidity standards:

Liquidity Coverage Ratio (LCR):
It requires banks to maintain enough high-quality liquid assets to meet their expected net cash outflows during a 30-day stress period.

Net Stable Funding Ratio (NSFR):
It encourages banks to rely on stable sources of funding over a longer period, generally based on a one-year horizon.

In simple terms:

LCR → Short-term liquidity protection
NSFR → Longer-term funding stability

What is a Bank Run?

A bank run occurs when a large number of depositors try to withdraw their money at the same time because they fear that the bank may not be able to meet its obligations.

This can create a chain reaction: withdrawals reduce the bank’s available liquidity, which may increase fear and encourage even more withdrawals.

Basel III’s liquidity requirements help banks prepare for such periods of financial stress.

What is the Countercyclical Capital Buffer?

The Countercyclical Capital Buffer (CCCB) is designed to strengthen banks during periods of rapid credit growth.

When economic conditions are favourable and lending is expanding quickly, banks may be required to build additional capital. During a downturn, this additional buffer can help absorb losses and support continued lending.

Thus, CCCB acts as a financial cushion that can be built during good times and used during difficult times.

Tier 1 Capital vs Tier 2 Capital

Bank regulatory capital is broadly divided into Tier 1 and Tier 2 capital.

Tier 1 capital is the stronger form of capital because it provides a more reliable cushion against losses.

Tier 2 capital provides an additional layer of protection but is considered less reliable than Tier 1.

Basel Norms in India

India has progressively adopted Basel standards through regulations issued by the Reserve Bank of India (RBI).

The implementation of Basel III in India was initially scheduled for March 2019 and was later extended. The COVID-19 pandemic also affected the implementation timeline.

The adoption of Basel standards has strengthened the focus of Indian banks on capital adequacy, liquidity, risk management and financial resilience.

Why are Basel Norms Important?

Basel norms help prevent banks from taking excessive risks without maintaining sufficient financial protection.

They strengthen:

• Capital adequacy
• Risk management
• Liquidity management
• Financial stability
• Depositor confidence

Ultimately, the purpose is to ensure that banks can absorb financial shocks while continuing to provide essential banking services.

Conclusion

Basel norms provide a common international framework for making banks safer and more resilient. Basel I focused mainly on credit risk and capital requirements, Basel II broadened the framework through its three-pillar approach, and Basel III further strengthened capital, leverage and liquidity requirements after the global financial crisis.
