This book introduces Asset and Liability Management (ALM) in the context of banks and insurance companies, offering a comprehensive guide to this critical strategy. Although ALM relies on fundamental frameworks, models can differ significantly between financial institutions due to varying risks and objectives. The authors, Marine Corlosquet-Habart, compare and contrast methodologies used by these two sectors to highlight both their commonalities and divergences, providing readers with a deeper understanding of ALM principles and practices across the board.
