Under the Babangida-era Structural Adjustment Programme, the Central Bank of Nigeria removed the prior moratorium on new commercial-bank licences in 1987, leading to a rapid expansion in licensed institutions from roughly 40 in 1986 to more than 120 by 1992. Liberalisation was paired with deregulation of interest rates and admission of merchant banks, but inadequate prudential supervision produced a wave of distressed banks that culminated in the 1995 Nigerian Deposit Insurance Corporation interventions.
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.
