Limitations of gap analysis:

Gap analysis assumes that the maturity time or repricing time of all positions in the same time period is the same, so it ignores the difference of maturity time or interest rate repricing time of different positions in the same time period;

Gap analysis only considers the interest rate risk caused by different repricing cycles, that is, repricing risk, but does not consider the interest rate risk caused by different adjustment ranges of benchmark interest rates of various financial products when the interest rate level changes, that is, benchmark risk;

Gap analysis also does not consider the change of payment time caused by the change of interest rate environment, such as ignoring the change of income of positions with option risk;

Non-interest income is increasingly becoming an important source of current income for banks, but most gap analysis fails to reflect the impact of interest rate changes on non-interest income;

Gap analysis mainly measures the impact of interest rate changes on the current earnings of banks, without considering the impact of interest rate changes on the overall economic value of banks, so it can only reflect the short-term impact of interest rate changes.
