What the policy did

On 12 April 2022 the Central Bank of Sri Lanka and Ministry of Finance announced a pre-emptive suspension of payments on all external commercial, bilateral and multilateral debt (excluding ADB/WB/AIIB) — Sri Lanka's first sovereign default. Triggered by terminal forex depletion (usable reserves below $50mn by April), compounded by the 2019 tax cuts' revenue loss, the 2021 fertiliser shock, COVID tourism collapse, and refusal to approach the IMF earlier. Initiated the external debt restructuring that subsequently framed the March 2023 IMF Extended Fund Facility.

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?".

Starting from comparable 1945 post-war conditions — same ethnicity, language, pre-war German institutional and industrial inheritance, and with the GDR inheriting a larger share of pre-war industrial capital in Saxony and Thuringia — the Federal Republic's Soziale Marktwirtschaft (Ordoliberal market economy with welfare state) versus the German Democratic Republic's planned economy with administered prices, state-enterprise production, and soft budget constraints produced by 1989 a canonical divergence that pattern-matches >=7 of 10 pre-registered extreme-outcome metrics, each drawn from a different publisher or methodology family.

Zimbabwean property-rights deterioration post-2000 (commercial-farm expropriation without compensation) precedes hyperinflation and output collapse; institutional mechanism is necessary, not merely monetary.

Zimbabwe's Fast Track Land Reform Programme (FTLRP, 2000-2002) combined with Reserve Bank of Zimbabwe deficit monetisation produced a canonical institutional and economic collapse 2000-2009 that manifests as >=7 of 10 pre-registered extreme-outcome metrics, each drawn from an independent data source and measuring a different causal layer (agricultural-capacity destruction, monetary collapse, output contraction, human-capital flight, humanitarian stress).

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.

Across developing and transition economies 1980-2020, secure private or household land-use rights predict stronger agricultural productivity growth — measured by cereal yields, agricultural value added per worker, and total-factor productivity in agriculture — than collective or state-allocation systems over long windows.

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).
