2. How the leading bank faced issues with its credit risk management system and what were the consequences?

Credit risk management is the process of assessing and mitigating the potential losses that may arise from lending money to borrowers who may default on their loans. It is a crucial aspect of banking, as it affects the profitability, liquidity, and solvency of the institution. However, credit risk management is not a simple task, as it involves complex models, data, and regulations that need to be constantly updated and monitored. In this section, we will explore how a leading bank faced challenges with its credit risk management system and what were the consequences of its inefficiencies.

Some of the main challenges that the bank faced with its credit risk management system were:

1. Lack of data quality and integration: The bank had multiple sources of data for its credit risk analysis, such as customer information, loan applications, credit scores, collateral values, market conditions, etc. However, these data sources were not well integrated and often contained errors, inconsistencies, and missing values. This made it difficult for the bank to have a comprehensive and accurate view of its credit portfolio and its risk exposure.

2. Outdated and rigid models: The bank relied on traditional statistical models to estimate the probability of default (PD), loss given default (LGD), and exposure at default (EAD) for each loan. These models were based on historical data and assumptions that did not reflect the current and dynamic nature of the credit market. Moreover, these models were not flexible enough to accommodate different types of loans, such as mortgages, personal loans, business loans, etc. As a result, the bank often underestimated or overestimated the credit risk of its loans, leading to suboptimal decisions and outcomes.

3. Inefficient and manual processes: The bank's credit risk management system required a lot of manual intervention and human judgment, which increased the operational costs and risks of errors and biases. For example, the bank had to manually review and approve each loan application, which was time-consuming and prone to mistakes. The bank also had to manually update and validate its credit risk models and parameters, which was tedious and inefficient. Furthermore, the bank had to manually generate and report its credit risk metrics and indicators, such as risk-weighted assets (RWA), capital adequacy ratio (CAR), expected credit loss (ECL), etc., which was cumbersome and delayed.

4. Non-compliance with regulations: The bank's credit risk management system did not comply with the latest regulatory standards and requirements, such as basel III and ifrs 9. These standards aimed to improve the resilience and transparency of the banking sector by imposing stricter rules and guidelines on credit risk measurement and management. However, the bank's system was not able to meet these rules and guidelines, as it lacked the data quality, model accuracy, process efficiency, and reporting capability that were required. This exposed the bank to the risk of penalties, fines, and reputational damage.

The consequences of these challenges were severe and detrimental for the bank, as they affected its performance, profitability, and sustainability. Some of the negative impacts that the bank experienced were:

- Higher credit losses and provisions: The bank suffered from higher credit losses and provisions, as it had a higher proportion of non-performing loans (NPLs) and write-offs in its portfolio. This reduced its net income and return on equity (ROE).

- Lower credit growth and market share: The bank experienced lower credit growth and market share, as it had a lower capacity and appetite to lend to new and existing customers. This limited its revenue and competitive advantage.

- Higher capital requirements and costs: The bank faced higher capital requirements and costs, as it had to maintain a higher level of capital to cover its credit risk exposure. This increased its cost of capital and reduced its return on assets (ROA).

- Lower customer satisfaction and loyalty: The bank had lower customer satisfaction and loyalty, as it had a slower and less responsive credit approval process, a higher and less transparent interest rate, and a lower and less flexible credit limit. This eroded its customer relationship and retention.
