Today's fiat digital currency coexistence is reshaping how money flows globally. Over 90% of central banks worldwide are developing CBDCs central bank digital currencies as of 2025, yet cash remains king in many places. How do these two systems work together without chaos? Let's unpack the current reality, challenges, and future of this new monetary landscape.
Current State of Coexistence
As of early 2026, four countries have fully launched retail CBDCs central bank digital currencies: Jamaica's JAM-DEX (2022), the Bahamas' Sand Dollar (2020), Zimbabwe's ZiG (2024), and Nigeria's e-Naira (2021). China's digital yuan, meanwhile, is in advanced pilots across 26 regions with 261 million users handling $26.4 billion in transactions. Stablecoins like USDC a regulated stablecoin pegged to the U.S. dollar and USDT a popular stablecoin issued by Tether process $30 billion daily, settling transactions in seconds at a fraction of traditional payment costs. This isn't a replacement of fiat-it's a parallel system where each plays a distinct role.
Technical Integration: How They Work Together
CBDCs central bank digital currencies typically run on permissioned blockchains controlled by central banks. For example, the Bahamas' Sand Dollar uses a two-tier system where the central bank manages the core ledger while commercial banks handle customer interfaces. It even supports offline transactions via NFC cards. Stablecoins, on the other hand, operate on public blockchains like Ethereum and Solana. USDC a regulated stablecoin pegged to the U.S. dollar transactions settle in under 30 seconds with $0.05 fees, compared to SWIFT's 1-5 days and 3-5% costs. However, interoperability remains tough. Only 37% of CBDCs central bank digital currencies pilots include cross-border features, though projects like mBridge a cross-border CBDC initiative connecting China, UAE, Thailand, and Hong Kong-connecting China, UAE, Thailand, and Hong Kong-have processed $22 billion in cross-border payments since 2023.
Economic Impact and Real-World Use Cases
MoneyGram's adoption of USDC a regulated stablecoin pegged to the U.S. dollar for remittances cuts transfer times from 3 days to under 10 minutes and reduces fees from 6.3% to 1.8% of transfer value. Nigeria's e-Naira reached 11.3 million active users (17% of adults) by Q1 2025, boosting financial inclusion. But risks lurk. The Bank of England warned in May 2025 that a rapid shift to stablecoins could trigger bank runs, with models showing potential deposit outflows of 15-25% during crises. Meanwhile, the IMF sees CBDCs central bank digital currencies as a tool for financial inclusion, projecting up to 20 percentage point gains in emerging markets.
Regulatory Landscape: A Global Patchwork
The EU's MiCA framework requires stablecoins to hold 1:1 reserves and daily attestations, but the U.S. lacks federal regulations, creating compliance headaches. The Basel Committee an international body setting banking standards recently mandated 100% high-quality liquid assets for stablecoin reserves, expected to lower issuance costs by 0.8-1.2 percentage points. CBDCs central bank digital currencies regulation is even more fragmented: only 28 countries have comprehensive laws for them, versus 64 with specific stablecoin rules. This patchwork makes global coordination difficult, with the Eurosystem's digital euro docs scoring 4.2/5, while Nigeria's e-Naira resources got 2.8/5 from developers.
Real-World Challenges and Solutions
Jamaica's JAM-DEX Jamaica's central bank digital currency reports only 42% merchant acceptance despite 63% consumer registration, mainly due to $280 per terminal integration costs. Central bank staff need 172 hours of specialized training to manage CBDCs central bank digital currencies infrastructure-twice as long as traditional systems. OpenPayd added stablecoin capabilities in Q1 2025 after 78% of clients requested it, showing enterprise demand. But technical documentation varies wildly: the Eurosystem's digital euro docs scored 4.2/5, while Nigeria's e-Naira resources got 2.8/5 from developers.
What's Next: The Future Roadmap
By 2027, experts predict three distinct layers: CBDCs central bank digital currencies for sovereign monetary policy, regulated stablecoins for cross-border commerce, and traditional fiat for legacy systems. Project Agorá, testing a unified ledger with 12 central banks, aims to integrate tokenized reserves and assets. MoneyGram expanded to EURC and GBPt stablecoins in May 2025, processing $4.2 billion quarterly in remittances. However, the transition will take time. The IMF's April 2025 report suggests the full shift won't happen before 2030, with stability concerns requiring careful management.
Can fiat and digital currencies really coexist without one replacing the other?
Yes, but they'll serve different roles. Fiat remains essential for domestic transactions and monetary policy control, while digital currencies handle specific use cases like cross-border payments or financial inclusion. Central banks aren't trying to eliminate cash-they're building complementary systems. For example, Nigeria's e-Naira targets unbanked populations while cash still dominates urban transactions. The Bank for International Settlements confirms most central banks view CBDCs as supplements, not replacements, for physical money.
Why do some countries launch CBDCs while others focus on stablecoins?
It depends on their goals. Countries like Jamaica and Nigeria launched CBDCs to improve domestic payment efficiency and financial inclusion, while stablecoin-focused regions (like the U.S.) prioritize innovation in cross-border finance. CBDCs are government-backed and controlled, making them ideal for monetary policy tools. Stablecoins, issued by private companies, offer faster innovation for global trade but face regulatory hurdles. The Bahamas chose a CBDC for its small economy, while the EU is testing a digital euro for broader eurozone integration.
Are stablecoins safer than CBDCs?
Not necessarily. Stablecoins like USDC and USDT rely on private reserves, which can be risky if not fully backed-though regulations like MiCA now require strict audits. CBDCs are directly backed by central banks, making them more stable but less flexible. The Bank of England found stablecoins could trigger bank runs during crises, while CBDCs risk financial repression if designed with negative interest rates. Both have trade-offs: stability vs. innovation, control vs. decentralization.
How do CBDCs and stablecoins interact in cross-border payments?
Through projects like mBridge, which connects China, UAE, Thailand, and Hong Kong. This system uses tokenized CBDCs for interbank settlements, while stablecoins handle retail transactions. For example, a Thai business can pay a Chinese supplier using a CBDC-backed token, while a Nigerian freelancer might receive USD via USDC. This hybrid approach cuts cross-border costs by 90% and speeds up settlements to minutes instead of days. However, interoperability remains limited-only 37% of CBDC pilots currently support cross-border use.
What's the biggest threat to this coexistence model?
Regulatory fragmentation. With 64 countries having stablecoin rules but only 28 having CBDC laws, businesses face inconsistent compliance requirements. The U.S. lacks federal stablecoin regulations, while the EU's MiCA is strict. This creates uncertainty for global companies. The IMF warns that without coordinated standards, digital currencies could fragment global finance instead of unifying it. Projects like Project Agorá aim to solve this, but widespread adoption will take years.

It's fascinating to see how each country is handling CBDCs and stablecoins. Jamaica's JAM-DEX has a 42% merchant acceptance despite high registration, which shows integration is tough. Nigeria's e-Naira is doing well with 11.3 million users, but the real story is how these systems complement each other. Cash still dominates in many places, and that's okay. The key is finding the right balance.
