- The Bahamas leads the world in central bank-issued cryptocurrencies with its Sand Dollar
- CBDCs offer many benefits in payment efficiency, speed, and reduced friction
- However, there are real privacy concerns and questions about government power
Centralized issuance
The topic of central bank digital currencies (CBDCs) is only beginning to break into mainstream awareness.
While many crypto enthusiasts hope more countries will follow El Salvador’s lead and adopt Bitcoin as legal tender, stablecoins appear to be a less ambitious route to sovereign adoption because they avoid the volatility that plagues Bitcoin. Stablecoins are simply digital versions of fiat currencies, pegged one-to-one to their traditional counterparts so their value does not fluctuate wildly.
Despite small examples such as the Swiss city of Lugano, where decentralized stablecoins like Tether (USDT) can be accepted as legal means of payment, many governments are developing their own centralized stablecoin alternatives.
Countries
According to PwC, none is more advanced than the Bahamas, where the central bank launched a digital version of the Bahamian dollar in October 2020. Commonly known as the Sand Dollar, it offers the same utility, legal status, and backing as the conventional fiat currency.
The benefits are numerous. Speed, efficiency, and security of payments top the list, and friction is reduced thanks to blockchain technology. The Bahamas also hopes the initiative will attract attention and help position the nation as a Caribbean crypto hub.
The traceable nature of the blockchain also helps combat money laundering, counterfeiting, fraud, and other financial crimes. Officials have noted additional advantages for lending markets, where a CBDC could “provide excellent records of inputs and outputs that can be used as supporting documentation for microloan applications.”
Drawbacks
Not all consequences of a CBDC are positive. There are very real privacy concerns: in theory, a government could track precisely what you buy, when you spend, and with whom you transact. Accounts could also be frozen at will—recall how Tether has frozen certain USDT tokens after hacks.
This raises the specter of dystopian scenarios in which governments could implement increasingly sci-fi measures, such as automatically tying social credit-style outcomes to spending behavior. Imagine a government knowing you spent $10 last night on a football bet and that information automatically affecting your credit score—or worse, your social standing. It is easy to see how such capabilities could empower more authoritarian regimes.
Is absolute sovereign control over citizens’ finances desirable? Governments already steer monetary policy through money printing, inflation control, and interest rates, which is one reason many turn to Bitcoin. CBDCs could enable targeted sanctions, provide full visibility into your net worth, tax liabilities, spending patterns, and many other aspects of life—given how central money is to modern interactions.
Conclusion
Fortunately, the most extreme visions remain largely the stuff of speculative fiction for now. Still, CBDCs bring those scenarios closer to reality and open the door to unprecedented power for sovereign states. Absolute centralization in digital money is a risky path, especially given the traceability of blockchains and associated digital wallet infrastructures.
To date, the Bahamas stands out as a leading example. In this case, authorities present the Sand Dollar as a step toward greater efficiency and an innovative tool to build a broader crypto ecosystem for the Caribbean nation.
Nevertheless, as other governments, including China, develop their own digital currencies, concerns about how that power might be used are legitimate—particularly in more authoritarian contexts.
