Norwegian krone 9.2% devaluation May 1986

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.

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.

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.

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).

Statutory price ceilings set below market-clearing prices reliably produce shortages, rationing via queue or privilege, quality degradation, and black-market arbitrage — across every documented episode where enforcement is sustained.

Statutory price ceilings set below plausible market-clearing prices produce measurable shortage indicators — stockouts, queue formation, black-market emergence, quality degradation, and in monetary- expansion contexts, large divergences between official and parallel- market prices.

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.
