A newly hired risk analyst at a mid-size bank is assisting in backtesting the bank's VaR model. Currently, the 1-day VaR is estimated at the 95% confidence level but the bank is considering a change to estimating 1-day VaR at the 99% confidence level, as recommended in the Basel framework. Which of the following statements concerning this change is correct?
A
The decision to accept or reject a VaR model based on the results of a backtest that uses a two-tailed 95% confidence level is less reliable when applied to a 99% VaR model than when applied to a 95% VaR model.
B
The 95% VaR model is less likely to be rejected by a backtest than the 99% VaR model.
C
When using a two-tailed 90% confidence level test in a backtest, there is a smaller probability of incorrectly rejecting a 95% VaR model than a 99% VaR model.
D
Using a 99% VaR model will lower the probability of committing both Type I error and Type II error.
