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TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.

Fiscal multipliers are state-dependent: large at ZLB, small near full employment; no single-number answer is policy-relevant.

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.

Following Koo (2008, 2014), the post-2008 advanced-economy recovery exhibited the diagnostic pattern of a balance-sheet recession: the private sector (households especially, plus non-financial business in the most leveraged countries) shifted simultaneously from net borrowing to net saving in pursuit of debt reduction, even when policy interest rates were at the zero lower bound.

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).
