Stress testing has evolved from a periodic regulatory exercise into a core decision-making tool for banks, regulators, and risk professionals. What was once treated as a standalone compliance activity is now expected to be fully integrated with IFRS 9 expected credit loss, capital adequacy, and management actions.
Yet in practice, many institutions still struggle to explain one consistent story.
The same portfolio produces different numbers for:IFRS 9 impairmentStress testing lossesCapital and risk-weighted assetsThese differences are often not wrong - but they are poorly connected, weakly governed, and difficult to explain under regulatory scrutiny.
This book addresses that gap.
Why This Book Was Written
Regulators today do not ask only what the numbers are.
They ask:Why do these numbers change under stress?How does stress flow through staging, ECL, and capital?Can the results be reproduced?Can management actions be justified?Can the logic be traced back to loan-level data?Answering these questions requires more than formulas. It requires a structured, auditable, and executable framework.
This book presents such a framework using SAS as the execution engine.
What Makes Stress Testing Different
Stress testing is not just about applying shocks.
It is about understanding:How macroeconomic deterioration affects credit risk parametersHow stage migration amplifies lossesHow forward-looking overlays change lifetime expectationsHow stressed losses translate into capital impactWhen stress testing is isolated from IFRS 9 and capital, it creates confusion rather than insight.
Integration turns stress testing into a powerful narrative tool.
Why SAS Is Central to This Framework
SAS remains the dominant platform in regulated banking environments for a reason
eterministic processingTransparent data handlingStrong governance and auditabilityProven scalabilityThis book does not treat SAS as a coding language.It treats SAS as an evidence platform - one that can support regulatory reviews, internal audits, and board-level discussions.
All examples in this book are implemented using clear, reproducible SAS logic, designed to be explained line-by-line.
Who This Book Is For
This book is written for:Risk professionals working on stress testing and IFRS 9Capital and ICAAP teamsModel validation and audit teamsRegulators and supervisory reviewersSAS practitioners supporting risk and finance functionsIt assumes familiarity with basic credit risk concepts but does not assume prior stress testing expertise.
