What the policy did

The Ley Bitcoin (Decreto Legislativo N° 57, approved 9 Jun 2021 by the Nuevas Ideas supermajority, effective 7 Sep 2021) made El Salvador the first country to adopt Bitcoin as legal tender alongside the US dollar (dollarised since 2001). The law obliged most merchants to accept BTC, exempted BTC transactions from capital-gains taxation, created a $150 million BANDESAL trust fund to guarantee automatic BTC-to-USD conversion for merchants, mandated BCR and Superintendencia del Sistema Financiero to publish implementing regulations, and established the regulatory scaffolding for the Chivo state wallet. Status as legal tender was formally removed in Dec 2024 under the IMF Extended Fund Facility condition (see sv_bitcoin_removal_imf_2024) while BTC retained optional-use status.

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?".

The Sep 2021 introduction of Bitcoin as legal tender plus the Chivo state-wallet launch and $30 per-adult BTC buy-in failed to produce a statistically significant change in El Salvador's total remittance volume or in the aggregate price of remittance services (World Bank remittance-cost series) relative to Central American and Caribbean peer countries.

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.

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.

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.

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.

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.
