The decision by El Salvador to adopt Bitcoin as legal tender in June 2021 marked a historic moment in the global financial landscape. While hailed by some as a bold step toward financial innovation and inclusion, the move has sparked intense debate among economists, policymakers, and financial institutions. This article examines the financial and market risks associated with Bitcoin’s legal tender status in El Salvador, drawing on empirical evidence from structural vector autoregressive (SVAR) models and analyzing its impact on monetary policy, remittances, the U.S. dollar index, and gold prices.

The Context of Bitcoin Adoption in El Salvador
In 2021, El Salvador became the first country to grant Bitcoin full legal tender status alongside the U.S. dollar. The government argued that this would promote financial inclusion, reduce remittance costs, and attract foreign investment. However, the country already operated under a dollarized economy since 2001, which had helped stabilize inflation—keeping it below 2% annually since 2012.

The introduction of Bitcoin introduced new complexities. With no central authority controlling its supply and extreme price volatility, Bitcoin challenges traditional monetary frameworks. As of recent reports, the Salvadoran government has incurred losses exceeding 35% on over 2300 Bitcoin purchased using public funds—highlighting the fiscal risks involved.
Bitcoin was intended to function not just as an investment but as a medium of exchange. However, adoption has been limited. According to economic theory, money must serve three key functions: a medium of exchange, a store of value, and a unit of account. While Bitcoin may fulfill the latter two under certain conditions, its volatility undermines its reliability as a transactional currency.
Theoretical Foundations: What Makes Money Work?
The concept of "legal tender" means the state recognizes a currency for settling debts and tax payments. However, legal status does not guarantee widespread acceptance. As Jevons (1876) noted, true monetary function arises from social convention and trust—not decree alone.
Kiyotaki and Wright (1992) emphasized that acceptability is endogenous—people use what others accept. In El Salvador, despite government incentives like the Chivo wallet and tax discounts for Bitcoin use, actual transactions remain minimal. This aligns with Umlauft (2018), who observed that cryptocurrencies are rarely used for everyday payments.
A key theoretical insight comes from chartalism: taxation creates demand for money. When citizens must pay taxes in a specific currency, they acquire it—even if it lacks intrinsic value. By allowing Bitcoin for tax payments, El Salvador attempted to engineer demand. Yet behavioral inertia, technological barriers, and volatility have limited its effectiveness.
Research Questions and Hypotheses
This study investigates three central questions:
- Does adopting Bitcoin as legal tender enhance or undermine economic stability?
- What is its impact on international remittances?
- How does Bitcoin interact with traditional safe-haven assets like gold in influencing monetary dynamics?
To address these, we test the following hypotheses:
- H1a: Bitcoin adoption negatively affects monetary policy transmission.
- H1b: It reduces monetary stability due to price volatility.
- H2: It improves remittance efficiency by lowering costs.
- H3: Bitcoin shares characteristics with gold, potentially supporting hedging strategies.
While H2 suggests potential benefits, empirical findings largely support H1a, H1b, and H3—with significant caveats.
Methodology: Measuring Bitcoin’s Economic Pass-Through
We employ a structural vector autoregressive (SVAR) model using monthly data from September 2010 to February 2022. Variables include:
- Bitcoin prices (USD)
- Remittances (in millions USD)
- Money multiplier
- U.S. Dollar Index (DXY)
- LBMA Gold Fixing Prices
The SVAR model captures dynamic responses to shocks in Bitcoin prices. Impulse response functions (IRFs) measure how each variable reacts over time after a one-time shock. Forecast error variance decomposition (FEVD) reveals how much of each variable’s fluctuations are explained by others.
Identification follows Blanchard and Quah (1988), imposing long-run restrictions to distinguish supply from demand shocks.
Empirical Findings: The Ripple Effects of Bitcoin Shocks
Impact on Remittances
Remittances account for nearly 24% of El Salvador’s GDP, making them vital for household income. The analysis shows that a positive Bitcoin price shock initially reduces remittance inflows by ~11% within one month. This drops to 9% at three months, 5.9% at six months, and stabilizes at 6.1% long-term.
Why the decline?
- Volatility risk: Senders may delay transfers during price surges, waiting for favorable exchange rates.
- Conversion uncertainty: High fees or unfavorable spreads when converting Bitcoin to USD deter usage.
- Behavioral caution: Users adopt a “wait-and-see” approach during extreme price swings.

Interestingly, robustness checks using alternative identification methods show a positive short-term effect (~46% increase), suggesting sensitivity to model assumptions. Still, the dominant trend indicates disruption rather than enhancement.
Effect on the Money Multiplier
Bitcoin operates outside traditional banking systems. If citizens shift savings into Bitcoin, bank deposits shrink—reducing banks’ ability to lend and create money.
Post-shock estimates reveal an immediate 8.8% drop in the money multiplier, moderating to 7.6% long-term. This implies that Bitcoin adoption could erode monetary expansion capacity, weakening central control over liquidity—despite El Salvador not having an independent monetary policy due to dollarization.
Robustness tests confirm this trend, with estimates ranging from –6.09% to –7.6%, underscoring persistent downward pressure on financial intermediation.
Influence on the U.S. Dollar Index
Despite using the USD officially, El Salvador’s Bitcoin policy affects perceptions of dollar strength regionally. A Bitcoin shock triggers an immediate 25% drop in the DXY, settling at 6% long-term.
This suggests that speculative capital flows react strongly to regulatory experiments involving digital assets. Investors may interpret such moves as economic instability signals, prompting short-term capital flight or currency hedging.
Robustness analysis deepens this finding—showing a peak decline of 27.54%, stabilizing at 11.15%, reinforcing concerns about spillover effects on reserve currency confidence.
Relationship with Gold Prices
Gold is a traditional safe haven during economic uncertainty. The study finds that Bitcoin price shocks cause an initial 4% dip in gold prices, growing to 6% long-term—indicating substitution effects during speculative episodes.
However, robustness checks reveal stronger negative impacts: up to 23.71% decline, suggesting that during high-volatility periods, investors may flee both assets or view Bitcoin as a competing store of value.
This challenges the idea of Bitcoin as “digital gold.” Instead, it behaves more like a speculative asset whose movements influence—even destabilize—traditional markets.
Frequently Asked Questions (FAQ)
Q: Has Bitcoin improved remittances in El Salvador?
A: Empirical evidence shows mixed results. While lower transaction fees were expected, volatility and low adoption have disrupted remittance flows rather than enhanced them.
Q: Does Bitcoin threaten El Salvador’s monetary stability?
A: Yes. By reducing bank deposits and distorting price signals, Bitcoin weakens financial intermediation and complicates macroeconomic management—even in a dollarized economy.
Q: Is Bitcoin acting like gold as a safe-haven asset?
A: Not consistently. While both are seen as inflation hedges, Bitcoin’s volatility causes inverse or correlated movements with gold during shocks—undermining its reliability as a stable store of value.
Q: Can other countries replicate El Salvador’s model?
A: Unlikely without strong institutional safeguards. Smaller economies with weak governance face higher risks of capital flight, fiscal losses, and financial instability.
Q: How does Bitcoin affect the U.S. dollar in El Salvador?
A: Although the USD remains dominant, investor sentiment reacts negatively to Bitcoin policy shifts—evident in DXY fluctuations—suggesting reputational spillovers.
Q: What lessons can policymakers learn?
A: Legal tender status doesn’t ensure adoption. Trust, stability, and usability matter more than legislation. Regulatory clarity and consumer protection are essential before integrating volatile digital assets into national economies.
Policy Implications and Conclusion
El Salvador’s experiment with Bitcoin as legal tender offers critical insights into the intersection of innovation and macroeconomic risk. While the intent—to boost inclusion and reduce remittance costs—was sound, outcomes have been disappointing:
- Limited adoption
- Fiscal losses from volatile holdings
- Disruption in remittance patterns
- Erosion of financial system depth
- Spillover effects on global asset markets
Bitcoin’s fixed supply and decentralized nature make it incompatible with active monetary policy tools. Even in dollarized economies, its integration introduces unpredictable behavioral and financial dynamics.
Policymakers considering similar steps must weigh innovation against stability. Regulatory frameworks should prioritize consumer protection, anti-money laundering compliance, and financial system resilience.

Ultimately, while digital currencies represent the future of finance, their implementation requires careful calibration—not legislative leaps of faith. El Salvador’s journey underscores that technological possibility does not equate to economic viability.
As research continues, one conclusion stands clear: for cryptocurrencies to support—not destabilize—national economies, they must first earn trust through consistency, transparency, and stability.
