问题如下:
According to incremental risk charge calculation, banks are required to:
选项:
A.estimate a liquidity horizon for each instrument in the portfolio and rebalance their portfolios at the end of the liquidity horizon.
B.build up a buffer of Tier 1 equity capital equal to 2.5% of risk- weighted assets in normal times.
C.focuses on its ability to whether a 30-day period of reduced/disrupted liquidity.
D.calculate the VaR using a 250-day period of stressed market conditions.
解释:
A is correct.
考点:the incremental risk charge
解析:
计算IRC (the incremental risk charge)时,银行需要估计组合中每种工具的liquidity horizon。例如,假设组合中一个AA+级的债券的liquidity horizon为3个月,如果3个月之后债券违约或者信用评级下降,银行将会使用另一个AA+级的债券来替代该债券。组合调整的频率取决于liquidity horizon,在进行这样的调整时,银行可能因为债券信用评级下调而遭受一定的损失,但通常情况下可以规避债券的default risk。选项A正确
选项B、C、D分别是capital conservation buffer, liquidity coverage ratio 和 the stressed VaR的计算方式。
老师A选项的解析前半句还能理解就是一个投资工具到期了需要补到组合中另一个相同期限的投资工具,评级下调属于CR,为什么说通常情况下可以规避default risk
