Reference material for flagship ECL topics, implementation notes, and reviewer support.
Explore core methodology, judgement-heavy topics, implementation notes, and trust material without losing the thread of the wider ECL programme.
Move through ECL by methodology, judgement, or implementation focus.
Six flagship modules across blueprint, data, staging, modelling, overlays, and controls.
Practical notes on scope, stage allocation, forward-looking estimation, and disclosure-ready evidence.
Readable implementation articles on recurring problem areas, review questions, and reporting themes.
How to Choose the Right ECL Measurement Approach
A practical guide to deciding when the general approach fits, when lifetime treatment is stronger, and when separate treatment is more defensible than forced pooling.
Designing Stage Transfer Rules That Management Can Defend
A practical approach to SICR design covering quantitative triggers, qualitative indicators, rebuttable presumptions, cure logic, and governance choices that keep stage movement credible.
Building Forward-Looking ECL Estimates With Practical Scenarios
How to introduce macroeconomic information into ECL using practical scenario design, transparent weighting, and a clear boundary between structured modelling and overlays.
Explaining Management Overlays Clearly
How to justify, quantify, approve, and communicate overlays so they read as disciplined responses to defined issues rather than vague management adjustments.
ECL Square combines technical ECL guidance with governed workflow. The methodology explains the judgement, and the platform layer operationalises data intake, stage transfer workflow, scenarios, overlays, approvals, and reporting.
