Basel III Framework: What Risk Managers Need to Know

The Basel III framework, developed by the Basel Committee on Banking Supervision (BCBS), is the cornerstone of bank regulation. Understanding Basel is essential for both the FRM exam and risk management practice.

Basel III Overview

Basel III was developed in response to the 2008 financial crisis, significantly strengthening bank regulation in three key areas:

Higher capital requirements — more and better quality capital
New liquidity standards — LCR and NSFR
Leverage ratio — a non-risk-based backstop

Capital Requirements

Three Pillars

Pillar 1: Minimum capital requirements for credit, market, and operational risk
Pillar 2: Supervisory review (ICAAP, SREP, additional buffers)
Pillar 3: Market discipline through disclosure

Capital Quality

Common Equity Tier 1 (CET1): Minimum 4.5% of RWA
Tier 1 Capital: Minimum 6% of RWA
Total Capital: Minimum 8% of RWA

Capital Buffers

Capital Conservation Buffer: 2.5% CET1
Countercyclical Buffer: 0-2.5% CET1
G-SIB Buffer: 1-3.5% CET1
D-SIB Buffer: Varies by jurisdiction

Basel III.1 (Endgame)

The final Basel III reforms include:

Output floor: Internal model capital cannot fall below 72.5% of standardized capital
Revised standardized approaches for credit, market, and operational risk
New operational risk framework replacing all previous approaches
FRTB for market risk

Risk-Weighted Assets

Credit Risk

Standardized Approach: External ratings drive risk weights
IRB Approaches: Internal models for PD, LGD, EAD

Market Risk

Standardized Approach (SA-TB): Sensitivity-based calculation
Internal Models Approach (IMA): Desk-level approval, ES-based

Operational Risk

New Standardized Approach: Business Indicator + Internal Loss Multiplier

Leverage Ratio

A non-risk-based backstop: Tier 1 Capital / Total Exposure ≥ 3%, preventing excessive balance sheet leverage regardless of risk weights.

Importance for FRM Candidates

Basel concepts appear across multiple FRM topics. Understanding the framework holistically — not just individual components — is essential for exam success.

Frequently Asked Questions

What are the three pillars of Basel III?▼

Pillar 1: Minimum capital requirements for credit, market, and operational risk. Pillar 2: Supervisory review process (ICAAP/SREP). Pillar 3: Market discipline through public disclosure requirements.

What is the minimum CET1 ratio under Basel III?▼

The minimum CET1 is 4.5% of risk-weighted assets, but with the capital conservation buffer (2.5%) and potentially countercyclical and G-SIB buffers, effective requirements are typically 10-13% or higher.

What is Basel III.1 (Endgame)?▼

Basel III.1 includes the final reforms: an output floor (internal model capital ≥ 72.5% of standardized), revised standardized approaches for all risk types, a new operational risk framework, and FRTB for market risk.

What is the leverage ratio under Basel III?▼

The leverage ratio is Tier 1 Capital / Total Exposure ≥ 3%. It is a non-risk-based backstop to prevent excessive balance sheet leverage regardless of how risk weights are calculated.
