Background of the Study
Risk quantification methods are vital for evaluating potential losses and guiding strategic decisions in investment banking. Guaranty Trust Bank (GTBank) has implemented various quantitative techniques—such as Value at Risk (VaR), stress testing, and scenario analysis—to measure and manage financial risk (Ifeanyi, 2023). These methods allow the bank to assess exposures under different market conditions and allocate capital more efficiently. The evolution of risk quantification practices has been driven by advancements in computational technologies and the increasing complexity of financial markets. GTBank’s approach integrates traditional statistical models with modern machine learning techniques to enhance the precision of risk assessments. However, accurately quantifying risk remains a challenge due to market volatility, data limitations, and model uncertainties. The study investigates how GTBank employs risk quantification methods to support investment decisions and mitigate potential losses. By analyzing historical risk data, model performance, and case studies of market disruptions, the research aims to identify both the strengths and limitations of current methods and propose improvements that can lead to more reliable risk assessments.
Statement of the Problem
Despite the use of advanced risk quantification methods, GTBank faces significant challenges in accurately predicting risk exposures in volatile market conditions. A major problem is the reliance on historical data that may not adequately represent future market behavior, leading to potential underestimation of risk (Olu, 2023). Additionally, discrepancies in model calibration and data quality can result in significant variations in risk estimates, undermining confidence in the quantification process. The rapid evolution of financial instruments further complicates the modeling process, as traditional methods may not capture the complexities of modern portfolios. These issues create uncertainty in capital allocation and risk management, ultimately impacting strategic decision-making. This study seeks to examine the limitations of current risk quantification methods at GTBank and to explore enhancements that can improve predictive accuracy and risk management outcomes.
