Q306: Calculate the Total Risk-Weighted Assets (RWA) for Credit Risk under the Standardised Approach of Basel II, given the following exposures:
1. ₹ 100 Crore loan to a corporate entity with an external ECAI rating of AAA.
2. ₹ 50 Crore loan to an unrated corporate entity.
(Note: Assume the regulatory risk weight for AAA is 20%, and for unrated is 100%).
2. ₹ 50 Crore loan to an unrated corporate entity.
(Note: Assume the regulatory risk weight for AAA is 20%, and for unrated is 100%).
✅ Correct Answer: A
The correct answer is A (₹ 70 Crore). Under the Standardised Approach (SA) of Basel II, banks must use ratings from External Credit Assessment Institutions (ECAIs) to assign risk weights to their exposures.
Statement 1 data: A ₹ 100 Crore exposure to a AAA-rated corporate attracts a 20% risk weight.
Therefore, the RWA is 100 * 0.20 = ₹ 20 Crore.
Statement 2 data: A ₹ 50 Crore exposure to an unrated corporate attracts a 100% risk weight.
Therefore, the RWA is 50 * 1.00 = ₹ 50 Crore.
Total RWA = ₹ 20 Crore + ₹ 50 Crore = ₹ 70 Crore.
Option B incorrectly assumes 100% weight for both.
Option C applies incorrect weights.
Option D only counts the unrated exposure.
Statement 1 data: A ₹ 100 Crore exposure to a AAA-rated corporate attracts a 20% risk weight.
Therefore, the RWA is 100 * 0.20 = ₹ 20 Crore.
Statement 2 data: A ₹ 50 Crore exposure to an unrated corporate attracts a 100% risk weight.
Therefore, the RWA is 50 * 1.00 = ₹ 50 Crore.
Total RWA = ₹ 20 Crore + ₹ 50 Crore = ₹ 70 Crore.
Option B incorrectly assumes 100% weight for both.
Option C applies incorrect weights.
Option D only counts the unrated exposure.
