1๏ธโฃ What is Basel III? โ Introduction & Background
Basel III is a comprehensive set of international banking regulations developed by the Basel Committee on Banking Supervision (BCBS), headquartered at the Bank for International Settlements (BIS) in Basel, Switzerland.
Why Was Basel III Introduced?
Basel III was introduced in December 2010 as a direct response to the 2008 Global Financial Crisis, which exposed critical weaknesses in the banking system:
- Banks held insufficient capital to absorb losses
- Excessive leverage (too much borrowing vs. capital)
- Poor liquidity management โ banks couldn’t meet withdrawal demands
- Lack of transparency in risk disclosure
- Lehman Brothers collapse triggered global panic

| Risk Coverage | Credit Risk only | Credit + Market + Operational | All + Liquidity + Leverage |
| Pillar System | โ No | โ 3 Pillars | โ 3 Pillars (enhanced) |

| Capital Buffers | โ None | โ None | โ CCB + CCyB + SIB |
| Capital Quality | Basic | Improved | Highest (CET-1 focus) |
| Trigger | Need for uniformity | Need for risk sensitivity | 2008 Financial Crisis |
4๏ธโฃ Three Pillars of Basel Framework
The Basel framework (originally introduced in Basel II, enhanced in Basel III) is built on three pillars:
Pillar 1
Minimum Capital Requirements
Defines how much capital banks must hold against credit, market & operational risks
Pillar 2
Supervisory Review
Regulators (RBI in India) review each bank’s internal risk assessment & capital planning
Pillar 3
Market Discipline
Banks must publicly disclose risk exposure, capital adequacy & risk management info
5๏ธโฃ Capital Structure โ CET1, AT1, Tier 2
| Type of Capital | Full Form | Quality | Components |
|---|---|---|---|
| CET-1 | Common Equity Tier 1 | ๐ข Highest quality | Equity shares + Retained earnings + Share premium |
| AT1 | Additional Tier 1 | ๐ก High quality | Perpetual non-cumulative preference shares + AT1 bonds (can convert to equity) |
| Tier 1 | Core Capital | ๐ข Going-concern capital | CET-1 + AT1 |
| Tier 2 | Supplementary Capital | ๐ Lower quality | Subordinated debt + Revaluation reserves + General provisions |
| Total Capital | Regulatory Capital | โ | Tier 1 (CET-1 + AT1) + Tier 2 |
โข Tier 1 = Going-concern capital โ absorbs losses while bank is still operating
โข Tier 2 = Gone-concern capital โ absorbs losses when bank is being wound up
โข CET-1 is the purest form โ equity shares are permanent, cannot be recalled
Tier 1 = CET-1 + AT1
6๏ธโฃ Capital Requirements & Ratios
| Requirement | Basel III (Global) | India (RBI) |
|---|---|---|
| Minimum CET-1 | 4.5% of RWA | 5.5% of RWA โฌ๏ธ |
| Minimum Tier 1 Capital | 6% of RWA | 7% of RWA โฌ๏ธ |
| Minimum Total Capital (CRAR) | 8% of RWA | 9% of RWA โฌ๏ธ |
| Capital Conservation Buffer | 2.5% | 2.5% |
| Countercyclical Buffer | 0โ2.5% | 0โ2.5% |
| Min Total incl. CCB | 10.5% | 11.5% โฌ๏ธ |
โข Global CRAR = 8% โ India CRAR = 9%
โข Global CET-1 = 4.5% โ India CET-1 = 5.5%
This is asked very frequently in JAIIB/CAIIB/Banking exams.
What are Risk Weighted Assets (RWA)?
Assets are assigned risk weights based on their risk level. Higher risk = higher weight = more capital required.
| Asset Type | Risk Weight | Example |
|---|---|---|
| Cash & Gold | 0% | No risk โ safest |
| Government Securities | 0% | Backed by sovereign guarantee |
| Loans to Banks (AAA rated) | 20% | Low counterparty risk |
| Home Loans (up to โน35 lakh) | 35% | Secured against property |
| Commercial Loans | 100% | Higher default risk |
| Venture Capital / Equity | 150%+ | Highest risk category |
7๏ธโฃ Capital Buffers โ CCB, CCyB, SIB Surcharge
| Buffer Type | Rate | Purpose | When Used |
|---|---|---|---|
| Capital Conservation Buffer (CCB) | 2.5% | Extra cushion to absorb losses during stress | Always maintained |
| Countercyclical Buffer (CCyB) | 0โ2.5% | Protect against excessive credit growth | Activated during economic boom |
| D-SIB Surcharge | 0.2%โ0.8% | Extra buffer for “Too Big to Fail” banks | For D-SIBs like SBI, ICICI, HDFC Bank |
โข CCB = Always ON (permanent extra cushion) โ like wearing a seatbelt always
โข CCyB = Switched ON/OFF by regulator โ like activating airbags only during crash risk
โข If CCB is breached โ Dividend/bonus restrictions on the bank
8๏ธโฃ Liquidity Standards โ LCR & NSFR
Basel III introduced two liquidity standards โ these were completely new and did not exist in Basel I or II.
| Standard | Full Form | Measures | Minimum | Time Horizon |
|---|---|---|---|---|
| LCR | Liquidity Coverage Ratio | Short-term liquidity resilience | โฅ 100% | 30 days |
| NSFR | Net Stable Funding Ratio | Long-term funding stability | โฅ 100% | 1 year |
HQLA Classification (for LCR)
| Level | Assets Included | Haircut |
|---|---|---|
| Level 1 HQLA | Cash, Government Securities, Central Bank Reserves | 0% (no haircut) |
| Level 2A HQLA | Corporate bonds (AA- & above), Covered bonds | 15% |
| Level 2B HQLA | Corporate bonds (A+ to BBB-), Equity shares (major index) | 25โ50% |
9๏ธโฃ Leverage Ratio
The leverage ratio is a non-risk-based measure that limits excessive borrowing. It acts as a backstop to the risk-based capital ratios.
| Parameter | Global (BCBS) | India (RBI) |
|---|---|---|
| Minimum Leverage Ratio | 3% | 3.5% โ 4% (higher for D-SIBs) |
| Numerator | Tier 1 Capital | |
| Denominator | Total Exposure (on-balance + off-balance sheet items) | |
๐ Risk Categories & Measurement Approaches
| Risk Type | What It Covers | Approaches |
|---|---|---|
| Credit Risk | Risk of borrower defaulting on loan | Standardised Approach (SA) / Internal Ratings-Based (IRB) |
| Market Risk | Risk from changes in market prices (interest rates, forex, equity) | Standardised / Internal Models Approach (IMA) |
| Operational Risk | Risk from internal failures (fraud, IT failures, process errors) | Basic Indicator / Standardised / Advanced Measurement |
1๏ธโฃ1๏ธโฃ India-Specific Requirements (RBI)
| Parameter | Global Basel III | India (RBI) | Difference |
|---|---|---|---|
| CRAR / CAR | 8% | 9% | +1% |
| CET-1 | 4.5% | 5.5% | +1% |
| Tier 1 | 6% | 7% | +1% |
| Total incl. CCB | 10.5% | 11.5% | +1% |
| Leverage Ratio | 3% | 3.5โ4% | +0.5โ1% |
| LCR | โฅ 100% | โฅ 100% | Same |
| NSFR | โฅ 100% | โฅ 100% | Same |

| Bucket 3 | 0.6% | SBI |
| Bucket 2 | 0.4% | โ |
| Bucket 1 | 0.2% | ICICI Bank, HDFC Bank |
1๏ธโฃ3๏ธโฃ PCA Framework & AT1 Bonds
Prompt Corrective Action (PCA) Framework
RBI’s PCA framework is a warning system triggered when banks breach Basel III thresholds on capital, asset quality, or profitability.
| PCA Trigger | Threshold | Risk |
|---|---|---|
| CRAR | Falls below 9% | Capital Risk |
| Net NPA | Exceeds 6% | Asset Quality Risk |
| CET-1 | Falls below 5.5% | Capital Risk |
| Leverage Ratio | Falls below 3.5% | Leverage Risk |

| Loss Absorption | Can be written down or converted to equity during stress |
| Trigger | When CET-1 falls below threshold (Point of Non-Viability) |
| SEBI Min Investment | โน1 crore (to protect retail investors after Yes Bank case) |
| Listed on | Stock exchanges (NSE/BSE) |
