What should be the duration of assets for the bank’s balance sheet to be immunized against the interest rate risk?
For the bank to be immunized against the interest rate risk, the duration gap should be zero.
Therefore, the duration of assets should match the duration of the liabilities on the bank's balance sheet.
duration gap = DA– DL*k
k = Total Liabilities/Total Assets
DA = DL x k
