# Credit Portfolio Monitoring

## Overview

Portfolio monitoring looks beyond single obligors to the shape of the entire credit book: concentrations, migrations, emerging loss trends, and compliance with risk appetite limits.

## When to Use

- Portfolio risk reporting for credit committees and boards
- Risk appetite and concentration limit oversight
- Comparing retail vs corporate book health
- Stress and ICAAP / capital discussions supported by portfolio data

## Core Practices

- Track exposure by segment, product, industry, geography, and rating band
- Monitor concentration (single-name, sector, collateral type)
- Analyze rating migration matrices and watchlist trends
- Measure NPA / delinquency formation, coverage, and write-offs
- Compare utilization vs sanctioned limits at aggregate levels
- Align portfolio metrics to stated risk appetite thresholds
- Investigate outliers and sudden migrations with root-cause analysis

## Key Portfolio Views

- Exposure mix (retail vs corporate; secured vs unsecured)
- Vintage / cohort loss curves
- Migration and flow into higher risk grades
- Concentration heat maps
- Expected vs realized losses and provisioning coverage

## Principles

- Diversification is a control — measure it deliberately
- Portfolio limits only work if breaches escalate
- Aggregate calm can hide pockets of severe stress
- Retail and corporate books need different lenses but one consolidated appetite story
- Data quality (ratings completeness, segment tags) determines signal quality

## Verification

- [ ] Concentration and appetite limits are defined and reported
- [ ] Migration and delinquency trends are reviewed on a fixed cadence
- [ ] Segment and product breakdowns are available, not only totals
- [ ] Limit breaches have escalation and remediation paths
