What the policy did

The Central Bank of Nigeria on 23 June 2015 issued a circular excluding 41 (later 43) import categories — including rice, cement, private jets, tomato paste, poultry, toothpicks, wheelbran, and textiles — from access to official foreign-exchange windows, forcing importers onto the parallel market. Framed as import-substitution industrial policy in the oil-price-collapse BOP crisis; in practice entrenched the multiple- exchange-rate regime and widened the parallel-market premium. Lifted October 2023 under Tinubu's FX unification.

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.

intended

↓

trade openness

regulatory.trade_openness

Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.

decreased · strong

more protectionist

Hard FX-denominated import restriction on 43 categories.

unintended / side-effect

↓

central bank independence

monetary.central_bank_independence

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.

decreased · moderate · unintended

lower independence (fiscal dominance, politicised appointments)

CBN directed industrial policy outside mandate; fiscal-dominance signalling.

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.

Canada’s long-run prosperity after the Canada–US Free Trade Agreement (1988) and NAFTA (1994) is more associated with market openness than with national industrial-policy initiatives.

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.

Estonia’s radical market reforms after independence in 1991 — including a currency board, flat tax, rapid privatisation, and full trade liberalisation — generated a cumulative GDP-per-capita convergence gain of at least 15 log-points by 2024 relative to a synthetic counterfactual constructed from gradual post-Soviet reform comparators (Latvia, Lithuania, Russia, Ukraine, Belarus, Kazakhstan).

Across countries 1990-2020, accession to a substantive free-trade agreement (FTA) — defined as a WTO-notified preferential-trade agreement going beyond MFN with measurable bilateral tariff reductions — is followed by higher trade openness and higher per-capita real GDP growth in the post-accession 5-year window than in the matched pre-accession 5-year window.
