This dissertation aims to illustrate the poor risk management practices by financial institutions that contributed to the global financial meltdown. It delves into the complex realities of practical risk management, encompassing factors like regulations, innovations, and the interconnectedness of various issues.
Chapter 1 introduces the concept of risk management in relation to profit generation and the emergence of the subprime crisis as a catalyst for the global financial turmoil. Chapter 2 outlines established risk management theories and discusses various types of risks faced by financial institutions. Chapter 3 examines the limitations of two commonly used risk management models, Value at Risk (VaR) and the KMV portfolio model.
Chapter 4 provides an overview of the subprime crisis and its causes, highlighting the role of financial innovations like collateralized debt obligations, structured investment vehicles, and credit default swaps. Chapter 5 delves into the inadequate risk evaluation practices of financial institutions, analyzing the shortcomings of credit rating agencies, hedge funds, and other critical factors that amplified the crisis.
Chapter 6 focuses on the case study of Lehman Brothers, examining its financial structure, reliance on short-term debt financing, and its failure to anticipate and mitigate the impact of the crisis. Chapter 7 investigates the case study of AIG, highlighting its exposure to credit default swaps and the weaknesses in its risk management models that contributed to its near-collapse.
Key terms and concepts explored in the dissertation include risk management, global financial meltdown, subprime crisis, financial innovations, systemic risk, Value at Risk (VaR), KMV portfolio model, credit rating agencies, hedge funds, liquidity risk, capital adequacy, transparency, Lehman Brothers, and AIG.
The meltdown was primarily caused by poor risk management, excessive financial innovation (like subprime mortgages), and systemic risks that interconnected global financial institutions.
The study critiques VaR for its inability to predict extreme market movements ("black swans") and its failure to account for liquidity risks during a crisis.
Lehman Brothers failed due to reliance on short-term debt, while AIG faced near-collapse due to massive exposure to Credit Default Swaps (CDS) and inadequate risk models.
These include Collateralized Debt Obligations (CDOs), Structured Investment Vehicles (SIVs), and Credit Default Swaps (CDS) that amplified systemic risk.
The agencies are criticized for inadequate risk evaluation and for giving high ratings to complex financial products that were actually high-risk.
