Asset liability management (ALM) aims to ensure liquidity and profitability by managing risks related to changes in interest rates, exchange rates, and credit. It involves balancing maturities of assets and liabilities to minimize liquidity risk. The asset liability management committee (ALCO) oversees the bank's ALM strategy, including product pricing, desired maturity profiles, and monitoring liquidity risk levels using ratios under the stock approach and gap analysis under the flow approach.
