Overview of Financial Risks and Regulatory Frameworks › Overview of Financial Risks and Regulatory Frameworks

Risk is the defining feature of financial markets. Every position, every trade, every strategic decision carries the potential for outcomes that deviate from expectations, sometimes favorably, often not. Throughout this book, you have built models to price assets, construct portfolios, and value derivatives. But models are only as useful as our ability to understand when they might fail, and portfolios are only as useful as our capacity to survive adverse market conditions. Risk management turns theoretical knowledge into practical survival.

The financial crisis of 2008 demonstrated with painful clarity what happens when risk management fails. Institutions that had accumulated vast exposures to mortgage-backed securities and their derivatives discovered that their models had vastly underestimated the probability of correlated defaults. Liquidity that had seemed abundant evaporated overnight. Counterparties that had appeared solvent became insolvent. The cascade of failures threatened the entire global financial system.

This chapter provides a systematic framework for understanding financial risks. We begin by categorizing the major risk types that institutions face: market risk, credit risk, liquidity risk, operational risk, and model risk. We then examine what effective risk management seeks to achieve and how regulatory frameworks, particularly the Basel Accords, shape institutional behavior. Finally, we explore how firms organize their risk management functions to identify, measure, monitor, and control these risks. This foundation prepares you for the detailed quantitative tools covered in subsequent chapters.
