Asset and liability management (ALM) in banks is concerned with several key activities:
* Maintaining the desired liquidity structure of the bank (I): Ensuring that the bank has enough liquid assets to meet its short-term obligations.
* Managing the factors affecting the structure and composition of a bank's balance sheet (II): This includes managing the mix of assets and liabilities to optimize returns and minimize risks.
* Focusing on the circumstances impacting the stability of income the bank generates over time (IV): Ensuring that the bank's income is stable and sustainable by managing interest rate risk, credit risk, and other factors that could affect profitability.
