The global financial landscape is evolving rapidly, and a groundbreaking paper by Harvard PhD candidate Matthew Ferranti—titled Hedging Sanction Risk: Cryptocurrencies in Central Bank Reserves—offers a compelling argument for why central banks should seriously consider allocating part of their international reserves to Bitcoin.
Originally published in three parts by the Liu Jiaolian blog, this 60-page academic study presents a rigorous, forward-looking analysis of how geopolitical risks, particularly financial sanctions, are reshaping reserve asset strategies. Rather than speculative price forecasting, the paper uses Bayesian probability models to assess Bitcoin’s role as a strategic hedge—not for profit, but for protection.
This article breaks down the core insights of Ferranti’s research, optimizes structure for clarity and SEO, removes redundant or promotional content, and integrates key concepts naturally for maximum readability and search relevance.
The Growing Threat of Financial Sanctions
Financial sanctions have become a dominant tool of geopolitical influence, especially wielded by the United States through institutions like the Office of Foreign Assets Control (OFAC). As of 2019, OFAC had sanctioned 8,755 entities, far surpassing the EU’s 2,136 and the UN’s 1,057.
Unlike traditional warfare, sanctions aim to isolate nations economically—but their effectiveness is declining. Research by Felbermayr et al. (2020) shows that sanction success rates have dropped to just 30% since 1995, despite increasing usage.
Yet, their real impact lies in chilling effects on financial sovereignty. When the U.S. freezes foreign reserves—such as with Russia in 2022—it undermines trust in fiat currencies as “safe-haven” assets. This event marked a turning point: if even sovereign wealth can be seized, no asset is truly secure unless outside centralized control.
Gold as a Historical Hedge—and Its Limitations
For decades, gold has served as the primary alternative to fiat reserves. After the 2008 financial crisis, central banks reversed decades of divestment and began accumulating gold. By 2020, gold accounted for 14.4% of global reserves, the highest in two decades.
Ferranti’s study reveals a strong correlation between military import sources and gold accumulation. Countries importing defense equipment from U.S. geopolitical rivals—like China or Russia—are statistically more likely to increase gold holdings. Why? Because they face higher risks of U.S. sanctions.
But gold isn’t perfect:
- Low liquidity compared to digital assets
- High logistical costs for transportation and storage
- Vulnerability to political interference—many nations store gold in foreign vaults (e.g., at the New York Fed), where access can be blocked
These limitations open the door for a new kind of reserve asset: one that’s both scarce and censorship-resistant.
Why Bitcoin Fits the Role of a Sanction-Resistant Asset
Bitcoin stands out due to its decentralized, permissionless nature. While exchanges and wallet providers may be regulated, the blockchain itself cannot be controlled by any single nation. As long as nodes exist globally, transactions continue uninterrupted.
Key advantages highlighted in the paper:
- Immutable ledger: No entity can reverse or freeze transactions
- Fixed supply: Capped at 21 million BTC, immune to inflationary policies
- Global distribution: Mining and node operation span over 100 countries, making coordinated shutdowns nearly impossible
Even after China’s 2021 mining ban, Bitcoin’s hashrate recovered within months—proving its resilience. Miners simply relocated or used tools like VPNs to mask operations.
Stablecoins, while useful for trading, are too centralized for strategic reserve purposes. Their reliance on fiat collateral makes them vulnerable to regulatory action—as seen when OFAC sanctioned Tornado Cash in 2022, targeting smart contracts rather than individuals.

Bitcoin vs. Gold: Complements, Not Substitutes
One of the paper’s most important findings is that Bitcoin and gold are not perfect substitutes, but rather incomplete alternatives in a reserve portfolio.
When sanction risk is moderate, both assets see increased demand. But when physical gold acquisition is difficult—due to cost, logistics, or political barriers—Bitcoin becomes a more attractive option.
The model suggests:
- Even without sanction risk, central banks should hold 2–3% in Bitcoin
- With moderate sanction risk, optimal allocation rises to 5%
- If gold access is restricted, Bitcoin allocation jumps to 10%
- With full flexibility, a balanced mix of gold and Bitcoin (around 5%) is ideal
For context, El Salvador—the most aggressive national adopter—holds only about 1.4% of its reserves in Bitcoin, well below the recommended threshold.
Addressing Common Criticisms
“Bitcoin Is Too Volatile”
Volatility is real—but declining over time. As adoption grows, extreme price swings diminish. Moreover, central banks don’t need daily liquidity; they prioritize long-term preservation of value.
“Bitcoin Mining Harms the Environment”
True: Bitcoin consumes ~0.5% of global electricity (per IEA). But this energy cost is the price of decentralization. For nations fearing asset seizure, environmental trade-offs may be acceptable for financial security.
“No Intrinsic Value”
Ferranti counters this by noting:
- Bitcoin has no viable substitute for trustless value transfer
- Its scarcity prevents devaluation
- Volatility doesn’t negate store-of-value potential—gold was also volatile historically
Strategic Implications for Global Currencies
Interestingly, the paper suggests that U.S. sanctions could inadvertently boost demand for both Bitcoin and the Chinese yuan (RMB). Since China’s geopolitical stance often opposes Western powers, RMB offers a negatively correlated alternative.
As sanction risks rise among U.S.-aligned nations:
- Demand for RMB may grow
- Incentive to adopt CBDCs increases
- Bitcoin gains appeal as a neutral, apolitical asset
Moreover, holding Bitcoin does not undermine a nation’s own CBDC—it may even enhance credibility by demonstrating commitment to financial resilience.
FAQ: Your Questions Answered
Q: Can a central bank really use Bitcoin as a reserve?
A: Yes—if stored securely using cold wallets and multi-signature protocols. Sovereign custody eliminates third-party risk.
Q: Isn't Bitcoin just speculation?
A: Not necessarily. Central banks don’t require high returns—they seek risk diversification. Bitcoin serves as insurance against systemic failures.
Q: What happens if governments ban Bitcoin?
A: Bans affect local exchanges and usage—but not global network integrity. As long as nodes operate elsewhere, Bitcoin survives.
Q: How does Bitcoin compare to other cryptocurrencies?
A: Bitcoin’s proof-of-work model and first-mover advantage make it more resilient than PoS chains like Ethereum, which face greater regulatory scrutiny and competition.
Q: Could Bitcoin ever replace the U.S. dollar?
A: Not imminently—but it can reduce dependency on any single reserve currency, promoting a multipolar financial system.
Q: Is now a good time for central banks to buy?
A: According to the model, yes—especially during bear markets when volatility is high but long-term fundamentals strengthen (e.g., post-halving scarcity).
The Road Ahead: Bitcoin’s Evolution into Institutional Maturity
We’re witnessing a pivotal shift. Bitcoin is transitioning from a speculative asset to a strategic reserve contender, much like gold did a century ago.
With the 2024 halving set to increase Bitcoin’s stock-to-flow ratio beyond that of gold (~120 vs. 62), its status as “digital hard money” will solidify.
This isn’t about price pumps—it’s about financial sovereignty, geopolitical hedging, and long-term stability.

Final Thoughts
Matthew Ferranti’s paper is the first to quantitatively model how sanction risk drives reserve diversification into cryptocurrencies. It moves beyond ideology and speculation, offering a data-driven case for Bitcoin as a legitimate component of national financial strategy.
As trust in traditional systems erodes and digital infrastructure matures, the convergence of CBDCs, cryptocurrencies, and decentralized finance will redefine what it means to hold value across borders.
Bitcoin may not replace fiat overnight—but it has earned a seat at the table.
