Compreendendo as moedas digitais dos bancos centrais: elas são o futuro?
The way people use money has shifted dramatically in the past decade, with digital payments, mobile wallets, and cryptocurrencies reshaping how value moves across the globe.

Amid this transformation, central banks are developing a new kind of money: Central Bank Digital Currencies (CBDCs).
Far from being just another fintech buzzword, CBDCs are state-backed digital currencies that could redefine financial systems, influence economic stability, and reshape global trade.
But the real question is: are they the future, or just another temporary experiment in monetary evolution?
What makes CBDCs particularly intriguing is their dual nature. On one hand, they offer the trust and backing of a nation’s central bank; on the other, they introduce innovative features that mimic the efficiency of modern fintech solutions.
Anúncios
This combination makes them one of the most ambitious financial experiments in recent history.
To truly understand their potential, it’s essential to explore not just the technology but also the social, political, and economic implications behind their rise.
What Are Central Bank Digital Currencies?
CBDCs are not cryptocurrencies, despite being built on similar digital infrastructure.
They are issued directly by a country’s central bank and represent legal tender, unlike decentralized assets such as Bitcoin or Ethereum.
- Key Difference: While cryptocurrencies are often volatile and unregulated, CBDCs are designed for stability and backed by the state.
- Two Models:
- Retail CBDCs – aimed at the general public, working as a digital version of cash.
- Wholesale CBDCs – used for interbank transactions, clearing, and settlements.
Por exemplo, o Bahamas launched the Sand Dollar in 2020, becoming the first nation to issue a fully operational CBDC.
China has tested the Digital Yuan across multiple provinces, and the European Central Bank is actively developing a Digital Euro project.
Understanding this distinction is crucial because it highlights that CBDCs are not just about innovation; they are about control and trust.
Unlike cryptocurrencies, which can collapse overnight due to speculation, CBDCs aim to provide the same stability as physical cash—only in digital form.
This is why governments see them as more than a financial tool: they are also a strategic instrument of sovereignty.

Why Are Governments Exploring CBDCs?
The push toward CBDCs is not random—it stems from a combination of technological advances, shifting consumer behavior, and economic pressures.
Inclusão Financeira
A World Bank report shows that 1.4 billion adults globally remain unbanked. CBDCs could provide access to secure digital money without requiring a traditional bank account, particularly in regions where banking infrastructure is weak.
However, inclusion is not just about giving people access to digital wallets. It’s also about creating systems that are affordable and user-friendly.
For example, if a CBDC requires a smartphone and constant internet access, adoption in rural areas could still be limited.
Policymakers must therefore design systems that adapt to local realities, rather than imposing one-size-fits-all solutions.
Payment Efficiency
Cross-border payments currently cost an average of 6.2% per transaction and take several days to settle.
CBDCs promise near-instant transfers with lower costs, potentially revolutionizing remittances for migrant workers sending money home.
Imagine a world where a Filipino nurse in London can send money to her family in Manila instantly, without losing a significant portion of her salary to intermediaries.
This kind of efficiency is not just economic—it’s social. It strengthens family bonds and reduces financial stress for millions.
Monetary Control
Governments see CBDCs as tools for enhancing oversight. Unlike cash, digital transactions leave a trace, allowing central banks to better monitor financial flows, fight tax evasion, and prevent money laundering.
Yet, with greater control comes greater responsibility. Transparency in how these systems are managed will be critical to prevent abuse.
Citizens will need guarantees that CBDCs will not become tools of overreach, where every purchase becomes visible to authorities.
Potential Benefits of CBDCs
1. Faster Transactions and Lower Costs
CBDCs could remove intermediaries in payment systems. Imagine sending money abroad in seconds, without paying hefty transfer fees to banks or platforms like Western Union.
This speed could also boost e-commerce and gig economies, where workers often wait days for payouts.
A CBDC system could allow freelancers, delivery drivers, and small businesses to receive earnings instantly, improving financial resilience.
2. Stronger Economic Stability
By giving central banks more granular control over money supply, CBDCs could enhance monetary policy. For instance, in times of crisis, stimulus payments could be deposited directly into citizens’ digital wallets.
Beyond emergencies, CBDCs could help fine-tune economic activity. For example, interest-bearing CBDC wallets could incentivize saving or spending depending on economic goals.
This precision could transform how governments manage recessions or inflationary spikes.
3. Support for Digital Economies
As e-commerce expands, digital-first payment systems align better with modern economies. A CBDC provides a secure and state-backed foundation, reducing dependence on private companies like PayPal or Visa.
In emerging markets, this could also empower local businesses by reducing reliance on foreign financial infrastructure.
A stable, government-backed digital currency may encourage entrepreneurship and attract global investors who value reliable payment ecosystems.
Key Risks and Concerns
Privacy vs. Surveillance
One of the most significant debates centers on privacy. A CBDC system could allow governments to monitor every transaction, raising fears of financial surveillance.
According to a 2023 survey by the Atlantic Council, 65% of respondents expressed concern over personal privacy in CBDC systems.
The challenge will be finding the right balance: ensuring compliance with anti-money laundering laws while protecting citizens’ right to privacy.
Some models propose anonymous low-value transactions but full traceability for larger ones, though critics argue this still gives governments too much power.
Impact on Banks
If individuals can hold money directly with the central bank, traditional banks may lose deposits, affecting their lending capacity.
Some economists warn this could destabilize the financial sector unless managed carefully.
Banks play a critical role in credit creation, and their disintermediation could trigger unintended consequences.
Policymakers are therefore exploring hybrid models where commercial banks remain central to distribution, while the central bank provides the underlying infrastructure.
Cybersecurity Threats
Unlike cash, CBDCs exist entirely in digital form, making them potential targets for cyberattacks. A major breach could undermine trust in the system, causing large-scale financial panic.
This risk means central banks must invest not only in cutting-edge security but also in transparent communication strategies. Citizens must trust not just the technology but also the institutions behind it.

Case Studies: Global CBDC Experiments
China – The Digital Yuan
China is leading the race, with over 260 million people testing the Digital Yuan. It has been used in retail payments, transport systems, and even the Beijing Winter Olympics.
However, concerns about state surveillance remain high.
The Chinese case demonstrates the political dimension of CBDCs. Beyond efficiency, the Digital Yuan is part of China’s strategy to reduce reliance on the US dollar in global trade.
This geopolitical angle highlights that CBDCs are not only financial innovations but also tools of national power.
Nigeria – The eNaira
Launched in 2021, Nigeria’s eNaira struggled with adoption. Limited smartphone penetration and lack of public trust slowed its uptake, highlighting that technology alone cannot solve systemic challenges like financial literacy and infrastructure.
Still, the eNaira project is valuable for its lessons. It shows that even with government backing, digital currencies require strong public engagement campaigns.
Without trust and usability, even the most advanced systems risk failure.
Europe – The Digital Euro
The European Central Bank is running pilot programs, but adoption remains cautious.
Privacy protection is the main concern among EU citizens, with policymakers emphasizing a balance between innovation and civil liberties.
Interestingly, the Digital Euro could also strengthen Europe’s independence from global payment giants, many of which are US-based.
By building its own digital infrastructure, Europe ensures greater sovereignty over its financial future.

Opportunities for Businesses and Consumers
CBDCs could reshape how companies and individuals interact with money.
- For Businesses: Faster settlements mean improved cash flow, reduced costs, and simplified accounting.
- For Consumers: Reduced fees on everyday transactions and secure, state-backed digital wallets.
A practical example is remittances. In countries like the Philippines, where remittances account for 9.3% of GDP, CBDCs could save families billions annually in transfer fees.
Moreover, CBDCs could encourage innovation in fintech ecosystems. Startups might build apps on top of CBDC infrastructure, offering new financial services while maintaining state-backed reliability.
This opens opportunities for local entrepreneurs who often face barriers accessing global financial platforms.
The Future of CBDCs: Evolution or Revolution?
Whether CBDCs become mainstream depends on adoption speed, consumer trust, and international cooperation.
They could either coexist with physical cash and digital payments or gradually replace them.
It’s worth remembering that technological shifts often face resistance before becoming normalized.
Credit cards, once distrusted, are now a global standard. Could CBDCs follow the same trajectory?
Equally, we should ask: will CBDCs look the same everywhere? Probably not. Each country will adapt the model to fit its cultural, economic, and political context.
This means the global landscape could become a patchwork of digital currencies, creating both opportunities and challenges for cross-border trade.

Conclusão
Understanding central bank digital currencies requires looking beyond the technology itself.
CBDCs are not simply another payment tool—they represent a potential reconfiguration of money, economics, and even civil liberties.
While the benefits of speed, inclusion, and efficiency are compelling, the risks of surveillance, instability, and cybersecurity cannot be ignored.
The future of CBDCs will depend on whether policymakers can strike the right balance between innovation and protection.
If achieved, CBDCs could indeed become the backbone of tomorrow’s financial system.
For now, the best approach is cautious optimism: recognize the immense opportunities, but remain vigilant about the risks.
After all, money is not just a tool of exchange—it’s also a reflection of how societies value freedom, trust, and control.
