Şimşek orthodox-pivot economic programme (Turkey 2023)

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.

UK Truss mini-budget 2022 gilt crisis reflected market confidence and institutional-framework rupture rather than an MMT-predicted hard fiscal limit, because the BoE restored order by intervening as issuer.

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.

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TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.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

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).

The September 2022 UK gilt-market dysfunction had its operative amplification mechanism in the foreign-currency-collateral exposure of the Liability-Driven Investment (LDI) leveraged-derivative chain in the UK pension system, not in a "fiscal limit" reached by the sovereign issuer.
