What the policy did

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.

Policy-content fingerprint — what this policy moved, on which axes

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.

Empirical evidence — linked hypotheses

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?".

Estonia adopted among the most radical market-liberalisation packages of any post-Soviet state — flat tax (26% universal rate, 1994), currency board (EEK pegged to DM/EUR, 1992), rapid privatisation, unilateral free trade, and minimal capital controls — and by 2007 had recovered to Soviet-era GDP per capita levels and substantially exceeded them, while Belarusian and Ukrainian peers had not recovered comparably.

Australia’s long expansion after the Hawke-Keating reforms (1983–1996) — including tariff cuts, financial deregulation, competition-policy introduction, and fiscal consolidation — is better predicted by market liberalisation than by sector-specific state direction.

Singapore's long-run prosperity and frontier convergence are better predicted by extreme trade openness, strong rule of law, competitive product and services markets, and high economic freedom than by state ownership or industrial targeting alone.

The African Continental Free Trade Area (AfCFTA), with trading formally commencing 2021-01-01, has not yet produced a measurable acceleration in aggregate African trade-openness ratios over the 2021-2024 window relative to a synthetic-control donor pool of non-AfCFTA emerging-market regions, because of slow tariff- schedule ratification, COVID-19 trade disruption, and weak cross-border infrastructure.
