What the policy did

CBN under Governor Lamido Sanusi announced 14 Aug 2009 takeover of five insolvent banks (Afribank, Finbank, Intercontinental, Oceanic, Union Bank) following joint CBN-NDIC stress-test, injected ~NGN 620bn liquidity, removed bank CEOs, and supported establishment of Asset Management Corporation of Nigeria (AMCON) in 2010 to resolve toxic assets. Five more institutions placed under intervention later.

Large welfare states sustain long-run real GDP per capita growth when paired with market flexibility (low product- and labour-market barriers), trade openness, and fiscal discipline (debt-to-GDP below 90%), but not when paired with rigid product and labour markets, in an OECD and rich- country panel 1980-2020.

Across the OECD 38, over 2000-latest, larger general government final consumption as a share of GDP is associated with slower growth in real household disposable income per capita, controlling for demographics, initial-income level, energy-price exposure, and trade openness.

Major episodes of financial deregulation — the 1999 US Gramm-Leach- Bliley repeal of Glass-Steagall, the 1986 UK Financial Services Act ("Big Bang"), Chile's 1974-1981 banking liberalisation, Sweden's late-1980s credit-market liberalisation, and Japan's 1996-2001 Big Bang — are followed within 10 years by higher-than-baseline incidence of banking crises, measured by the Laeven-Valencia Systemic Banking Crisis Database, and by elevated credit-to-GDP gaps per BIS.

Germany's Schuldenbremse (constitutional debt brake adopted 2009 and binding on the federation from 2016) did not produce a sustained growth or investment collapse over 2010-2019 (pre-COVID) at the single-country time-series level.

The Soviet central-planning system, having already exhibited TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.
