What the policy did

After speculative attack drained reserves $75B→$36B in late 1998, BCB widened crawling band 13 January 1999 under outgoing Francisco Lopes, then moved to full float 15 January 1999 under new BCB president Armínio Fraga. Real depreciated R$1.21 → R$2.00 by March. Ended Plano Real's 1994-1998 soft-peg phase; enabled subsequent inflation-targeting regime adoption.

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?".

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.

Every documented modern hyperinflation episode (Cagan ≥50% monthly inflation, Hanke-Krus catalogue) since 1900 falls into one of two categories: (a) the issuing state had material foreign-currency or gold-clause obligations, hard-currency-pegged debt, or external market dependency that left it operating effectively as a currency-user (Weimar reparations, Hungary 1945-46 occupation obligations, Yugoslavia FX debt, Zimbabwe USD obligations 2007+, Venezuela USD oil revenue dependency, Argentina USD debt, Lebanon USD-pegged banking system, Turkey 2021-2024 FX-denominated debt), or (b) the issuing state experienced a documented physical supply collapse independent of the monetary regime (Weimar Ruhr occupation, Hungary post-WW2 occupation/reparation, Zimbabwe land-reform output collapse, Venezuela oil-sector collapse).

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.

Argentina has experienced 12 distinct episodes of annual inflation exceeding 50% since 1945, each preceded by a fiscal deficit exceeding 4% of GDP financed via central bank money creation.

In a panel of advanced economies 1987-2007, base-money expansion and broad money growth correlate positively with asset-price indices (equity, real estate) but only weakly with headline CPI inflation.

Over 50+ year horizons since the 1971 collapse of Bretton Woods, major fiat currencies (USD, GBP, EUR legacy components, JPY, AUD) have lost substantial purchasing power against hard assets (gold, broad commodity baskets, residential real estate).

Every documented hyperinflation episode since 1900 (Weimar Germany, post-WW2 Hungary, Yugoslavia 1990s, Zimbabwe 2000s, Venezuela 2010s-2020s, among others) was preceded by fiscal dominance — a state of affairs where monetary policy is subordinated to financing government deficits that cannot be financed by taxation or market-rate borrowing.
