What the policy did

Following the collapse of successive heterodox plans under Sarney, Brazilian CPI reached 1,972% in 1989 (annualised Dec-on-Dec) and peaked at 84.3% monthly in March 1990 — the highest monthly rate of Brazil's hyperinflation era. Widespread use of BTNF fiscal indexation for all contracts; daily repricing; overnight market concentrated M4. Transition crisis: Collor inherited the 80% March monthly rate and responded with the Plano Collor asset freeze.

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.

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?".

Truss 2022 mini-budget shows that unfunded fiscal expansion above the ZLB triggers sharp bond-market and currency responses through expected-inflation and risk-premium channels.

Across the 2008-2014 ZLB era and the 2020-2021 pandemic-response window, large-scale de-facto monetary finance of fiscal expansion in the US, Japan, and the Eurozone did not produce headline-CPI inflation consistent with naive quantity-theoretic monetisation predictions: cumulative central-bank balance-sheet expansion exceeded 15% of GDP while CPI YoY remained below 3% in each economy across both windows.

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TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.

Post-2008 large-scale asset purchase programmes by the Federal Reserve, ECB, Bank of England, and Bank of Japan produced a measurable divergence between asset-price inflation (equities and residential real estate) and headline consumer-price inflation until roughly 2021.

Across OECD economies 1995-2021, the cumulative fiscal multiplier on real output at the zero lower bound (defined as quarters with policy rate ≤ 0.50% AND inflation expectations anchored below 2.5%) exceeds 1.2 at horizon h=8 quarters, while the comparable normal-regime multiplier is below 0.7.

Post-2008 quantitative easing operated principally through a Minsky-style financialisation channel — collateral-revaluation, portfolio-rebalancing into long-duration risk assets, and a yield-driven compression of risk premia — rather than through the textbook quantity-theoretic broad-money or expectations channels.

Abenomics' combined monetary-fiscal expansion lifted Japanese inflation and output partially but failed to durably escape the deflation equilibrium, consistent with NK models of near-permanent ZLB traps.
