Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Financial-sector regulation — banking separation, capital requirements, cross-border activity rules, derivatives oversight.
De jure and de facto independence of the central bank from fiscal authority. Per D.1.5 scope, one of the framework's defensible monetary positions.
On 14 June 2023 the Central Bank of Nigeria collapsed its multiple exchange-rate windows (official, I&E, SMIS, Investors', BDC) into a single willing-buyer-willing-seller regime at the Investors & Exporters window, effectively floating the naira. The official rate moved from ~N460/$ to ~N750/$ on day one and to N1,600+/$ by mid-2024. Complemented by the October 2023 lifting of the 43-item FX import ban introduced under Buhari. Intended to end the FX rationing / parallel-market premium that had made Nigeria an outlier in sub-Saharan Africa.
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.
