Introduction Slide – Model Risk Management in Credit Risk: Governance and Monitoring

Model Risk Management in Credit Risk: An Essential Practice.

Overview

Model Risk Management (MRM) in credit risk is essential for ensuring that models used for risk assessment, pricing, and decision-making are accurate, reliable, and compliant.
Strong governance and ongoing monitoring are critical to mitigate risks from flawed or misused models, especially as regulatory scrutiny increases.
This presentation covers governance frameworks, monitoring practices, and practical tools for effective MRM in credit risk.
Key insights include the importance of clear roles, robust policies, and continuous oversight to safeguard credit risk models.

Key Discussion Points – Model Risk Management in Credit Risk: Governance and Monitoring

Supporting Context for Model Risk Management in Credit Risk: Governance and Monitoring.

Main Points

Model risk governance establishes clear roles, responsibilities, and policies for model development, validation, and use, ensuring transparency and accountability.
Effective governance aligns with regulatory standards such as SR 11-7, requiring board and senior management oversight, defined policies, and resource allocation.
Ongoing monitoring is crucial to verify model performance, detect issues early, and ensure compliance with evolving regulations and market conditions.
Weak governance or monitoring can lead to significant financial and reputational losses, as seen in high-profile cases like the 2012 Value-at-Risk model failure.

Code Example: Model Risk Management in Credit Risk: Governance and Monitoring

Code Description

This Python code demonstrates a simple framework for monitoring model performance in credit risk, including data quality checks and performance metrics.

import pandas as pd
import numpy as np

# Simulate credit risk model output
np.random.seed(42)
data = pd.DataFrame({
    'predicted_default': np.random.rand(1000),
    'actual_default': np.random.binomial(1, 0.1, 1000)
})

# Data quality check
missing_values = data.isnull().sum()
print("Missing values:", missing_values)

# Performance metric: Accuracy
accuracy = (data['predicted_default'].round() == data['actual_default']).mean()
print("Model accuracy:", accuracy)

# Alert if accuracy drops below threshold
if accuracy < 0.8:
    print("Alert: Model performance below threshold")
else:
    print("Model performance within acceptable range")
