In February 2015 the Central Bank of Ireland introduced binding loan-to-value and loan-to-income mortgage caps under SI 47/2015 (Housing Loan Requirements Regulations), capping LTI at 3.5x income and applying tiered LTV limits with defined "allowance" portions for banks. The framework, refined in subsequent annual reviews, reshaped Irish mortgage-credit conditions and is regarded as a textbook macroprudential intervention against credit-driven house-price cycles.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
