The global financial landscape is undergoing a quiet but profound transformation, driven by the growing momentum behind central bank digital currencies (CBDCs). A comprehensive survey conducted by the Bank for International Settlements (BIS) reveals that while most central banks are still in research and experimental phases, a significant shift is underway—especially among emerging market economies. These nations are moving faster, with stronger motivations and clearer timelines for launching CBDCs than their developed counterparts.
This article explores the latest findings from the BIS survey, highlighting key trends in CBDC development, regional disparities in adoption, legal considerations, and the evolving role of digital currencies in reshaping financial systems worldwide.
Understanding Central Bank Digital Currency (CBDC)
Central bank digital currency represents a new form of money issued by a nation’s central bank—distinct from physical cash and traditional reserve accounts. Unlike cryptocurrencies such as Bitcoin, CBDCs are sovereign-backed, regulated, and designed to coexist with or potentially replace existing monetary forms.
There are two primary types of CBDCs:
- Retail (General-Purpose) CBDC: Intended for use by the general public in everyday transactions, much like digital cash.
- Wholesale CBDC: Restricted to financial institutions for interbank settlements and large-scale transfers.
Each variant serves different economic objectives, from enhancing payment efficiency to strengthening monetary policy implementation.

Global Survey Overview: Methodology and Participation
The BIS survey gathered responses from 66 central banks, including 21 from advanced economies and 45 from emerging markets—representing approximately 75% of the world’s population and 90% of global GDP. Conducted in late 2019, this follow-up to the 2018 study aimed to assess progress, motivations, legal readiness, and projected timelines for CBDC issuance.
Key questions focused on:
- Whether central banks are researching or developing CBDCs
- Types of CBDCs under consideration
- Stages of development (research, experiment, pilot)
- Motivations for adoption
- Legal authority to issue digital currency
- Public cash usage trends
- Perceptions of private digital tokens (e.g., stablecoins)
The data paints a clear picture: while widespread deployment remains distant for many, a select group of emerging economies are accelerating toward real-world implementation.
Research Progress: From Concept to Pilot
Interest in CBDCs continues to grow. Around 80% of responding central banks are now engaged in some form of CBDC research—an increase from 70% in 2018. Notably:
- Half are exploring both retail and wholesale models.
- 40% have advanced beyond conceptual work into experimentation or proof-of-concept stages.
- 10% have launched pilot programs.
Crucially, all institutions at the development or pilot stage come from emerging market economies.
This trend underscores a growing divergence between developed and developing nations in terms of urgency and execution. While advanced economies proceed cautiously, many emerging markets see CBDCs as a strategic tool for modernizing outdated financial infrastructure.
Key Motivations Driving CBDC Development
Central banks cite diverse reasons for pursuing digital currencies. However, motivation intensity varies significantly between regions.
Retail CBDC Drivers
For emerging markets, the top motivations include:
- Financial inclusion: Extending access to banking services for unbanked populations.
- Payment efficiency: Reducing transaction costs and settlement times.
- Cash dependency reduction: Lowering logistics and security costs tied to physical currency.
- KYC/AML compliance: Enhancing transparency and anti-money laundering controls.
In contrast, developed economies prioritize payment security above all else. Their concern isn’t cash scarcity but ensuring continued public access to central bank money as physical currency use declines.
A telling insight: nearly half of surveyed central banks are actively studying cash usage patterns. One-third anticipate a decline in cash reliance within six years—confirming broader global trends where cash remains in circulation primarily as a store of value rather than a medium of exchange.
Wholesale CBDC Drivers
While interest in wholesale CBDCs is generally lower, emerging markets again show stronger motivation, particularly around:
- Domestic payment efficiency
- Financial stability
- Settlement finality
Advanced economies focus more on improving cross-border payment efficiency, aligning with international initiatives like those led by the Financial Stability Board (FSB).
Legal Frameworks: A Major Hurdle
A critical barrier to CBDC rollout is legal authorization. The survey found:
- Only 25% of central banks already have or are close to obtaining legal powers to issue digital currency.
- 33% lack such authority.
- 40% remain uncertain.
Given that most central bank mandates were established before the digital era, this uncertainty is expected. Without clear legislative backing, even technically ready institutions may delay launches.

When Will CBDCs Launch? Projected Timelines
Despite cautious optimism overall, a small but influential cohort of central banks expects imminent deployment.
- 10% believe it’s possible they’ll issue a retail CBDC within three years—double the figure from 2018.
- 20% foresee issuance within six years.
These figures may seem modest, but their demographic weight is significant: central banks planning near-term launches represent one-fifth of the global population.
In contrast, prospects for wholesale CBDCs are dimmer. Many institutions that previously considered short-term issuance have since downgraded their plans—highlighting technical challenges with distributed ledger technology (DLT) in high-volume environments.
Notably:
- All central banks confident about near-term retail CBDC launches are from emerging markets.
- Among those considering mid-term issuance, 90% are emerging economies.
- Virtually all advanced economies view both retail and wholesale CBDC issuance as unlikely in the next six years.
Private Digital Tokens: Stablecoins and Cryptocurrencies
Beyond CBDCs, the survey examined attitudes toward private-sector digital assets.
Cryptocurrencies
Most central banks report minimal use of cryptocurrencies like Bitcoin for either domestic or cross-border payments. They remain niche tools with limited scalability or regulatory acceptance.
One notable exception: a country experiencing severe economic instability reported rising crypto adoption—underscoring how decentralized currencies can fill voids during national crises.
Stablecoins
Stablecoins—digital tokens pegged to real-world assets—are attracting increasing scrutiny. However:
- Only 60% of central banks are analyzing their impact on monetary and financial stability.
- Most institutions not assessing stablecoin risks are from emerging markets—many of which rely heavily on remittances.
This gap highlights an urgent need for greater coordination and research into how global stablecoins could disrupt local financial systems.
Case Study: Caribbean Pioneers in CBDC Innovation
Two standout examples illustrate how small economies are leading the charge:
Bahamas – Account-Based Sand Dollar
The Central Bank of The Bahamas launched Project Sand Dollar, a retail CBDC pilot using an account-based model. Designed to serve remote islands with limited banking access, the digital currency:
- Operates 24/7
- Is non-interest-bearing
- Has holding limits to prevent disintermediation
- Integrates with a centralized KYC system
With mobile penetration at 93%, the initiative aims to boost financial inclusion while reducing reliance on costly cash logistics.
Eastern Caribbean – Token-Based DCash
The Eastern Caribbean Central Bank (ECCB) introduced DCash, a token-based CBDC built on distributed ledger technology. Serving eight island nations, it enables peer-to-peer transactions through regulated financial intermediaries. Like the Sand Dollar, it emphasizes accessibility, security, and anti-money laundering compliance.
These pilots reflect a shared vision: leveraging digital currency not just for modernization, but for inclusive growth.
Frequently Asked Questions (FAQ)
What is a central bank digital currency (CBDC)?
A CBDC is a digital form of sovereign currency issued by a central bank. It functions as legal tender and can be used by individuals or institutions for payments and settlements.
Which countries are closest to launching a CBDC?
Several emerging economies—including The Bahamas, Eastern Caribbean nations, China (with its digital yuan), and Jamaica—are already running live pilots or have launched limited rollouts.
Can CBDCs replace physical cash?
While not intended to fully replace cash immediately, CBDCs may gradually reduce dependency on physical currency—especially in regions where cash distribution is logistically challenging or expensive.
Are CBDCs based on blockchain?
Some are. For example, the ECCB’s DCash uses distributed ledger technology. Others, like Sweden’s e-krona proposal or the Bahamian Sand Dollar, rely on centralized account-based systems.
Do CBDCs threaten privacy?
Most designs prioritize traceability for regulatory compliance but include safeguards against mass surveillance. Anonymity levels vary by country and design choice.
How do stablecoins differ from CBDCs?
Stablecoins are privately issued and often backed by reserves; CBDCs are government-backed and regulated. While stablecoins offer innovation, they carry counterparty and systemic risks absent in CBDCs.
Final Thoughts: The Path Forward
The BIS survey confirms that CBDC development is accelerating, particularly in emerging markets where digital currency offers transformative potential. Though most central banks remain in exploratory phases, a growing number are transitioning from theory to action.
Three imperatives emerge:
- Strengthen international collaboration through platforms like the BIS Innovation Hub.
- Clarify legal frameworks to empower central banks with necessary authority.
- Expand research into private digital tokens, especially stablecoins with global reach.
As technology evolves and public demand shifts, the line between possibility and necessity will blur. The future of money isn’t just digital—it’s being redefined today.
