Credit Risk Assessment: Default Probability Model and VaR Calculation

Introduction

Credit risk assessment is a cornerstone of financial stability, enabling institutions to quantify the likelihood of borrower default and manage exposure to potential losses. In modern finance, the integration of advanced statistical models has become essential for evaluating creditworthiness and risk mitigation. This article explores the development and application of a default probability model, which quantifies the likelihood of default, and the Value at Risk (VaR) calculation, a critical tool for assessing portfolio risk. By examining these models in tandem, the article highlights their interdependence and the role they play in comprehensive risk management frameworks.
