Correct Answer: C

Explanation:

Under Basel II.5, the market risk capital requirement is calculated using both VaR and stressed VaR at the 99.0% confidence level with multiplication factors applied. The formula is:

Market Risk Capital = max(VaR_t-1, m_c × VaR_{60-day Avg}) + max(sVaR_t-1, m_s × sVaR_{60-day Avg})

Where:

• VaR_t-1 = Latest available 10-day VaR at 99.0% confidence level = 451 million
• VaR_{60-day Avg} = Average 10-day VaR of previous 60 days at 99.0% confidence level = 413 million
• sVaR_t-1 = Latest available 10-day stressed VaR at 99.0% confidence level = 995 million
• sVaR_{60-day Avg} = Average 10-day stressed VaR of previous 60 days at 99.0% confidence level = 1,106 million
• m_c = multiplication factor for VaR = 3
• m_s = multiplication factor for stressed VaR = 3

Calculation:

• VaR component = max(451, 3 × 413) = max(451, 1,239) = 1,239 million
• Stressed VaR component = max(995, 3 × 1,106) = max(995, 3,318) = 3,318 million
• Total capital requirement = 1,239 + 3,318 = 4,557 million

Therefore, the correct capital requirement is USD 4,557 million.

Key Points:

• Basel II.5 introduced stressed VaR to address limitations of traditional VaR during periods of market stress
• The capital charge uses the higher of current VaR or scaled average VaR
• The multiplication factor of 3 is applied to the average values
• Only the 99.0% confidence level values are used for regulatory capital calculation
