Market Ledger Interpretability Index — Pilot
The Market Ledger Interpretability Index is an attempt to describe the current readability of mortgage advisory markets.
This index does not measure performance, outcomes, or quality of advice.
It does not rank firms, score providers, or evaluate suitability.
Its sole focus is interpretability:
the extent to which client-facing communication allows a non-expert to form a stable and repeatable understanding of risk, responsibility, and decision structure.
Why interpretability matters
Mortgage advisory operates at the intersection of institutional process and individual decision-making.
While disclosure requirements are broadly satisfied across the market, interpretation remains highly individualized.
Different clients can read the same materials and arrive at materially different understandings of risk.
Interpretability addresses this gap.
A market is interpretable when:
- risk is structured rather than scattered
- variables are operationalized rather than abstract
- responsibility is framed explicitly rather than transferred implicitly
- similar disclosures produce similar understanding across readers
When these conditions are absent, transparency exists without clarity.
What this index measures
The Interpretability Index evaluates recurring structural patterns observed in client-facing mortgage advisory materials, including:
- how risk is introduced and sequenced
- whether variables are linked to explicit triggers
- how responsibility is distributed through language
- whether hierarchy exists between central and peripheral risks
- whether disclosures function as decision interfaces or as compliance artifacts
The index is derived from pattern-level assessments published by Market Ledger, including Assessment 002.
What this index does not measure
This index explicitly does not assess:
- individual firms or advisors
- pricing, competitiveness, or product suitability
- regulatory compliance
- consumer outcomes
Interpretability is not a proxy for quality.
It is a prerequisite for meaningful comparison and informed decision-making.
How to read the index
The Interpretability Index uses qualitative status tiers rather than numerical scores.
These tiers are designed to describe structural conditions, not to produce rankings.
The purpose of the index is comparative over time, not competitive between actors.
Pilot scope and limitations
This is a pilot index.
Its scope is intentionally limited:
- no named entities
- no numeric scoring
- no historical trend claims
The index establishes a baseline.
Future iterations may refine categories, expand scope, or introduce longitudinal comparison.
Relationship to Market Ledger assessments
The Interpretability Index aggregates structural signals identified in Market Ledger assessments.
Assessments examine patterns in depth.
The index summarizes their implications at the market level.
Together, they form a shared interpretive layer rather than a judgment mechanism.
