Basel III Capital Adequacy, CET1, CCB Shortfall & Dividend Distribution Constraints

5 Linked Numerical Questions
Official IIBF Case Scenario & Financial Data:

Pragati Commercial Bank Ltd. (a scheduled commercial bank in India, non-D-SIB) reports the following capital components and Risk-Weighted Assets (RWA) as on 31st March 2026:

Capital / RWA ComponentAmount (₹ Crore)
Paid-up Equity Share Capital & Free Reserves (CET1 before deductions)₹7,200 Crore
Intangible Assets (Goodwill & Deferred Tax Assets deducted from CET1)₹400 Crore
Perpetual Debt Instruments (Additional Tier 1 — AT1 Eligible)₹1,400 Crore
Subordinated Debt & General Provisions (Tier 2 Eligible)₹2,000 Crore
Credit Risk RWA₹76,000 Crore
Market Risk RWA₹14,000 Crore
Operational Risk RWA₹10,000 Crore
Question 1.1 • 2 Marks

What is the Net Common Equity Tier 1 (CET1) Capital and the CET1 Ratio (%) of Pragati Commercial Bank?

A ₹7,200 Cr (7.20%)
B ₹6,800 Cr (6.80%)
C ₹8,200 Cr (8.20%)
D ₹6,800 Cr (7.55%)
Correct Answer: Option B — ₹6,800 Cr (6.80%) Net CET1 = Gross CET1 - Regulatory Deductions (Goodwill/Intangibles/DTA); CET1 % = Net CET1 / Total RWA
  • Step 1: Net CET1 Capital = ₹7,200 Cr - ₹400 Cr (Intangibles/DTA) = ₹6,800 Crore.
  • Step 2: Total RWA = Credit RWA (₹76,000 Cr) + Market RWA (₹14,000 Cr) + Operational RWA (₹10,000 Cr) = ₹1,00,000 Crore.
  • Step 3: CET1 Ratio = (₹6,800 / ₹1,00,000) × 100 = 6.80%.
IIBF Examiner Tip: Goodwill, intangible assets, and DTA dependent on future profitability are always deducted 100% from CET1.
Question 1.2 • 2 Marks

What is the Total Tier 1 Capital Ratio and Total CRAR (%) of the bank?

A Tier 1 = 8.20%; Total CRAR = 10.20%
B Tier 1 = 8.60%; Total CRAR = 10.60%
C Tier 1 = 6.80%; Total CRAR = 8.80%
D Tier 1 = 8.20%; Total CRAR = 11.50%
Correct Answer: Option A — Tier 1 = 8.20%; Total CRAR = 10.20% Tier 1 = Net CET1 + AT1; Total Capital = Tier 1 + Tier 2; Total CRAR = Total Capital / Total RWA
  • Step 1: Total Tier 1 Capital = Net CET1 (₹6,800 Cr) + AT1 (₹1,400 Cr) = ₹8,200 Crore -> Tier 1 Ratio = 8.20%.
  • Step 2: Total Capital = Tier 1 (₹8,200 Cr) + Tier 2 (₹2,000 Cr) = ₹10,200 Crore.
  • Step 3: Total CRAR = (₹10,200 / ₹1,00,000) × 100 = 10.20%.
IIBF Examiner Tip: Always verify that Tier 2 admitted for minimum CRAR does not exceed 2.0% of RWA (here ₹2,000 Cr is exactly 2.0% of ₹1,00,000 Cr).
Question 1.3 • 2 Marks

As per RBI Basel III norms, the bank must maintain 5.5% Minimum CET1 + 2.5% Capital Conservation Buffer (CCB) = 8.0% CET1, and 11.5% Total CRAR (including CCB). What is the bank’s CET1 shortfall to fully meet the 2.5% CCB?

A ₹1,200 Crore (1.20% of RWA)
B ₹1,300 Crore (1.30% of RWA)
C ₹500 Crore (0.50% of RWA)
D Zero shortfall (6.80% > 5.50%)
Correct Answer: Option A — ₹1,200 Crore (1.20% of RWA) CET1 Shortfall (including CCB) = (8.0% Required CET1 - Actual CET1 %) × Total RWA
  • Step 1: Required CET1 including CCB = 5.5% (Min CET1) + 2.5% (CCB) = 8.0% of RWA = ₹8,000 Crore.
  • Step 2: Actual Net CET1 = ₹6,800 Crore (6.80%).
  • Step 3: CET1 Shortfall = ₹8,000 Cr - ₹6,800 Cr = ₹1,200 Crore (1.20% of RWA; available CCB is only 6.80% - 5.50% = 1.30%).
IIBF Examiner Tip: Because actual CET1 is 6.80% (above 5.5% min CET1, providing 1.30% towards CCB), the bank falls in the third quartile of CCB and faces capital conservation restrictions on dividends/bonuses.
Question 1.4 • 2 Marks

In addition to raising ₹1,200 Crore of CET1, how much additional Total Capital is required so that Total CRAR reaches the full 11.50% (9% + 2.5% CCB) regulatory requirement?

A ₹100 Crore additional (Total shortfall ₹1,300 Crore)
B ₹1,200 Crore additional
C ₹1,500 Crore additional
D No additional capital beyond the ₹1,200 Cr CET1
Correct Answer: Option A — ₹100 Crore additional (Total shortfall ₹1,300 Crore) Total CRAR Shortfall = (11.50% - Actual CRAR %) × Total RWA
  • Step 1: Required Total Capital @ 11.50% of ₹1,00,000 Cr RWA = ₹11,500 Crore.
  • Step 2: Existing Total Capital = ₹10,200 Crore (10.20%). Total Shortfall = ₹11,500 - ₹10,200 = ₹1,300 Crore.
  • Step 3: Once ₹1,200 Crore of CET1 is raised, ₹100 Crore more (CET1 or AT1 up to 1.5% cap) is needed to reach ₹11,500 Crore.
IIBF Examiner Tip: Notice AT1 is currently ₹1,400 Cr (1.40% of RWA), so ₹100 Cr (0.10%) of AT1 or CET1 can fill the remaining gap.
Question 1.5 • 2 Marks

If Pragati Commercial Bank has a Total Exposure Measure (On-Balance Sheet + Off-Balance Sheet Credit Equivalent) of ₹2,05,000 Crore, what is its Basel III Leverage Ratio, and does it comply with RBI norms for a non-D-SIB bank?

A 4.00% — Complies (≥ 3.5% norm)
B 4.98% — Complies (≥ 3.5% norm)
C 3.32% — Fails (< 3.5% norm)
D 3.51% — Complies
Correct Answer: Option A — 4.00% — Complies (≥ 3.5% norm) Basel III Leverage Ratio = Tier 1 Capital / Total Exposure Measure
  • Step 1: Tier 1 Capital = ₹8,200 Crore.
  • Step 2: Total Exposure Measure = ₹2,05,000 Crore.
  • Step 3: Leverage Ratio = (₹8,200 / ₹2,05,000) × 100 = 4.00%. Since 4.00% ≥ 3.50% (and even ≥ 4.00% D-SIB norm), it fully complies.
IIBF Examiner Tip: Remember RBI Leverage Ratio thresholds: 4.0% for D-SIBs (SBI, HDFC Bank, ICICI Bank) and 3.5% for all other scheduled commercial banks.

What is the Credit Risk-Weighted Assets (RWA) for the Sovereign (Central + State Govt) and Regulatory Retail portfolios combined?

A ₹3,000 Crore
B ₹3,400 Crore
C ₹4,400 Crore
D ₹5,000 Crore
Correct Answer: Option B — ₹3,400 Crore Credit RWA = ∑ (Exposure × Risk Weight %)
  • Step 1: Central Govt G-Secs & RBI Cash = ₹5,000 Cr × 0% = ₹0 Crore.
  • Step 2: State Govt Guaranteed Advances = ₹2,000 Cr × 20% = ₹400 Crore.
  • Step 3: Qualifying Regulatory Retail Portfolio = ₹4,000 Cr × 75% = ₹3,000 Crore.
  • Step 4: Combined RWA = ₹0 + ₹400 + ₹3,000 = ₹3,400 Crore.
IIBF Examiner Tip: Central Government exposures carry 0% credit risk weight (though they carry 2.5% Market Risk Specific Risk weight if held in HFT/AFS).
Question 2.2 • 2 Marks

What is the Total Credit Risk-Weighted Assets (RWA) across all 5 asset classes listed in the table?

A ₹6,450 Crore
B ₹7,450 Crore
C ₹8,250 Crore
D ₹9,050 Crore
Correct Answer: Option B — ₹7,450 Crore Total Credit RWA = Sovereign/Retail RWA + Housing RWA (35%) + Unrated Corporate RWA (150%)
  • Step 1: Sovereign + Regulatory Retail RWA = ₹3,400 Crore.
  • Step 2: Residential Housing Loans (≤ ₹30L, LTV ≤ 80%) = ₹3,000 Cr × 35% = ₹1,050 Crore.
  • Step 3: Unrated Corporate Exposures (> ₹200 Cr aggregate banking exposure) = ₹2,000 Cr × 150% = ₹3,000 Crore.
  • Step 4: Total Credit RWA = ₹3,400 + ₹1,050 + ₹3,000 = ₹7,450 Crore.
IIBF Examiner Tip: Remember RBI’s enhanced 150% risk weight on unrated corporate exposures where total banking system exposure exceeds ₹200 Crore.
Question 2.3 • 2 Marks

Calculate the Operational Risk Capital Charge under the Basic Indicator Approach (BIA) from the 3-year Gross Income data (FY24: +₹1,400 Cr, FY25: -₹300 Cr, FY26: +₹1,800 Cr).

A ₹240 Crore
B ₹145 Crore
C ₹160 Crore
D ₹217.50 Crore
Correct Answer: Option A — ₹240 Crore KBIA = 15% × Average of POSITIVE Annual Gross Income over last 3 years
  • Step 1: Exclude FY25 (-₹300 Cr negative Gross Income) from both numerator and denominator.
  • Step 2: Average Positive Gross Income (FY24 & FY26) = (₹1,400 Cr + ₹1,800 Cr) / 2 = ₹1,600 Crore.
  • Step 3: Operational Risk Capital Charge (KBIA) = 15% of ₹1,600 Crore = ₹240 Crore.
IIBF Examiner Tip: The #1 IIBF BFM trap: dividing by 3 instead of 2 when one year has negative Gross Income!
Question 2.4 • 2 Marks

Convert the Operational Risk Capital Charge of ₹240 Crore into Equivalent Operational Risk RWA (using standard 12.5 multiplier).

A ₹2,400 Crore
B ₹3,000 Crore
C ₹2,666.67 Crore
D ₹1,920 Crore
Correct Answer: Option B — ₹3,000 Crore Operational Risk RWA = Operational Risk Capital Charge × 12.5
  • Step 1: Operational Risk Capital Charge = ₹240 Crore.
  • Step 2: Equivalent Operational Risk RWA = ₹240 Crore × 12.5 = ₹3,000 Crore.
IIBF Examiner Tip: If an exam question specifically asks to use RBI 9% minimum CRAR reciprocal (100/9 = 11.11), ₹240 × (100/9) = ₹2,666.67 Crore.
Question 2.5 • 2 Marks

If Market Risk Capital Charge is ₹160 Crore (Equivalent Market RWA = ₹160 × 12.5 = ₹2,000 Crore), what is the bank’s Total RWA (Credit + Market + Operational) and Minimum Required Capital @ 11.5% (including CCB)?

A Total RWA = ₹12,450 Cr; Required Capital = ₹1,431.75 Cr
B Total RWA = ₹10,450 Cr; Required Capital = ₹1,201.75 Cr
C Total RWA = ₹12,450 Cr; Required Capital = ₹1,120.50 Cr
D Total RWA = ₹11,850 Cr; Required Capital = ₹1,362.75 Cr
Correct Answer: Option A — Total RWA = ₹12,450 Cr; Required Capital = ₹1,431.75 Cr Total RWA = Credit RWA + Market RWA + Operational RWA; Required Capital = Total RWA × 11.5%
  • Step 1: Total RWA = ₹7,450 Cr (Credit) + ₹2,000 Cr (Market) + ₹3,000 Cr (Operational) = ₹12,450 Crore.
  • Step 2: Required Capital @ 11.5% (9% CRAR + 2.5% CCB) = ₹12,450 × 0.115 = ₹1,431.75 Crore.
IIBF Examiner Tip: Always check whether the question asks for 9% Minimum Capital (₹1,120.50 Cr) or 11.5% Capital including CCB (₹1,431.75 Cr).

Facility / Collateral DetailAmount / Parameter
Financial Guarantee (Bank Guarantee substituting financial obligation)₹200 Crore (CCF = 100%)
Performance Bank Guarantee (Bid Bond / Supply Performance)₹300 Crore (CCF = 50%)
Self-Liquidating Documentary Letter of Credit (LC for Merchandise)₹250 Crore (CCF = 20%)
Unconditionally Cancellable Undrawn Cash Credit Commitment₹400 Crore (CCF = 0%)
Cash Margin / Fixed Deposit Collateral (0% Haircut) against Financial BG₹40 Crore
Question 3.1 • 2 Marks

What is the Credit Equivalent Amount (CEA) before collateral deduction for the Financial Bank Guarantee (₹200 Cr) and Performance Bank Guarantee (₹300 Cr) combined?

A ₹250 Crore
B ₹350 Crore
C ₹400 Crore
D ₹500 Crore
Correct Answer: Option B — ₹350 Crore CEA = Notional Off-Balance Sheet Principal × Credit Conversion Factor (CCF %)
  • Step 1: Financial Guarantee CEA = ₹200 Cr × 100% CCF = ₹200 Crore.
  • Step 2: Performance Guarantee CEA = ₹300 Cr × 50% CCF = ₹150 Crore.
  • Step 3: Combined CEA = ₹200 Cr + ₹150 Cr = ₹350 Crore.
IIBF Examiner Tip: Financial Guarantees are direct credit substitutes (100% CCF), whereas Performance Guarantees carry 50% CCF.
Question 3.2 • 2 Marks

What is the Credit Equivalent Amount (CEA) for the Documentary Merchandise LC (₹250 Cr) and Unconditionally Cancellable Undrawn CC Limit (₹400 Cr)?

A ₹50 Crore and ₹0 Crore
B ₹125 Crore and ₹80 Crore
C ₹50 Crore and ₹80 Crore
D ₹250 Crore and ₹0 Crore
Correct Answer: Option A — ₹50 Crore and ₹0 Crore Short-term Self-Liquidating Trade LC CCF = 20%; Unconditionally Cancellable Commitment CCF = 0%
  • Step 1: Self-liquidating Trade LC CEA = ₹250 Cr × 20% CCF = ₹50 Crore.
  • Step 2: Unconditionally cancellable undrawn working capital commitment CEA = ₹400 Cr × 0% CCF = ₹0 Crore.
IIBF Examiner Tip: Commitments with original maturity ≤ 1 year get 20% CCF, > 1 year get 50% CCF, and unconditionally cancellable at any time get 0% CCF.
Question 3.3 • 2 Marks

What is the Total Net Credit Exposure (E*) across all facilities after deducting the ₹40 Crore Cash Margin (0% haircut, same currency)?

A ₹400 Crore
B ₹360 Crore
C ₹310 Crore
D ₹440 Crore
Correct Answer: Option B — ₹360 Crore Net Exposure (E*) = Total CEA - Eligible Financial Collateral after Haircut
  • Step 1: Total Gross CEA = ₹200 Cr (Fin BG) + ₹150 Cr (Perf BG) + ₹50 Cr (Trade LC) + ₹0 Cr = ₹400 Crore.
  • Step 2: Less Cash/FD Margin in same currency (0% Haircut) = ₹40 Crore.
  • Step 3: Net Credit Equivalent Exposure (E*) = ₹400 Cr - ₹40 Cr = ₹360 Crore.
IIBF Examiner Tip: Cash/Bank own FD in the same currency has 0% volatility haircut under the Comprehensive Approach.
Question 3.4 • 2 Marks

Given the corporate borrower is externally rated "A" (50% Risk Weight), what is the Risk-Weighted Assets (RWA) and Minimum Capital Required @ 9% CRAR?

A RWA = ₹180 Crore; Capital = ₹16.20 Crore
B RWA = ₹200 Crore; Capital = ₹18.00 Crore
C RWA = ₹360 Crore; Capital = ₹32.40 Crore
D RWA = ₹180 Crore; Capital = ₹20.70 Crore
Correct Answer: Option A — RWA = ₹180 Crore; Capital = ₹16.20 Crore RWA = Net Exposure (E*) × Counterparty Risk Weight %; Min Capital = RWA × 9%
  • Step 1: RWA = ₹360 Crore × 50% Risk Weight = ₹180 Crore.
  • Step 2: Minimum Capital @ 9% CRAR = ₹180 Crore × 9% = ₹16.20 Crore (or ₹20.70 Cr @ 11.5% with CCB).
IIBF Examiner Tip: Remember Corporate External Rating Risk Weights in India: AAA = 20%, AA = 30%, A = 50%, BBB = 100%, BB & below = 150%.
Question 3.5 • 2 Marks

If instead of Cash Margin, the borrower pledged ₹100 Crore of AAA Corporate Debt (Haircut Hc = 4%) in a mismatched currency (FX Haircut Hfx = 8%) against a ₹100 Crore exposure (He = 0%), what is the Adjusted Collateral Value?

A ₹88.00 Crore
B ₹88.32 Crore
C ₹96.00 Crore
D ₹92.00 Crore
Correct Answer: Option B — ₹88.32 Crore Adjusted Collateral Value = C × (1 - Hc - Hfx)
  • Step 1: Under Basel III Comprehensive Approach formula: E* = max{0, [E × (1 + He) - C × (1 - Hc - Hfx)]}.
  • Step 2: Adjusted Collateral Value = ₹100 Cr × (1 - 0.04 - 0.08) = ₹100 Cr × 0.88 = ₹88.00 Crore (or ₹88.32 Cr if multiplicative; Basel formula is additive: 1 - Hc - Hfx = 0.88 -> ₹88.00 Cr).
IIBF Examiner Tip: In the Basel formula E* = max{0, E(1+He) - C(1-Hc-Hfx)}, Hc and Hfx are subtracted additively: (1 - 0.04 - 0.08) = 0.88.

Frequently Asked IIBF Exam Questions (BFM Paper 2)

What are the domestic corporate external rating risk weights under RBI Basel III Standardized Approach?

AAA = 20%, AA = 30%, A = 50%, BBB = 100%, BB & below = 150%, Unrated = 100% (or 150% if aggregate exposure from the banking system exceeds ₹200 Crore).

How does the Countercyclical Capital Buffer (CCCyB) work under Basel III?

CCCyB ranges from 0% to 2.5% of RWA (to be met with CET1) and is activated by RBI only when credit-to-GDP gap and supplementary indicators signal excessive systemic credit growth. Currently in India, CCCyB is maintained at 0%.
