The rise of digital currencies is reshaping the global financial landscape, introducing transformative shifts in cross-border payments, monetary sovereignty, and financial regulation. As blockchain-based innovations gain momentum, their influence on the existing international monetary system—long dominated by the U.S. dollar—has become increasingly significant. This article explores how stablecoins, central bank digital currencies (CBDCs), and other digital assets are redefining currency dynamics, with a focus on technological evolution, economic implications, and strategic responses.
Core Digital Currency Types: Features, Limitations, and Future Prospects
Bitcoin – A Volatile Asset, Not a True Currency
Bitcoin, as the flagship cryptocurrency, remains highly speculative due to its extreme price volatility. This undermines its functionality as a reliable value store or medium of exchange, limiting its role primarily to that of a financial asset rather than actual currency. While debates continue over whether bitcoin behaves more like a risk-on or safe-haven asset, its fixed supply cap prevents it from being used as a tool for macroeconomic stabilization. Nevertheless, its underlying blockchain technology holds vast potential beyond digital money—especially in secure, decentralized record-keeping and smart contracts.

The Rise and Legacy of Stablecoins: From Libra to Global Adoption
Facebook’s proposed Libra (later Diem) project was halted by U.S. regulators, but its vision had lasting impact. The idea of combining global digital platforms with dollar-backed digital money sparked what’s known as the "catfish effect"—prompting central banks worldwide to accelerate their own central bank digital currency (CBDC) initiatives.
Today’s stablecoin ecosystem includes three main types:
- Fiat-collateralized (e.g., USD-pegged)
- Commodity-backed (e.g., gold-linked)
- Hybrid models combining fiat and crypto reserves
These instruments have evolved into critical infrastructure within the digital economy—particularly dollar-pegged stablecoins, which dominate the market.
Digital Yuan: Strategic Design and Scalability Challenges
China's digital yuan (e-CNY) was launched with a cautious approach—limited to replacing M0 (physical cash). While this minimizes disruption to commercial banks, it also restricts broader use cases, especially in enterprise transactions and international settlement.
To enhance global utility—particularly through mechanisms like the mBridge (a multilateral CBDC payment corridor developed by China, Hong Kong, Singapore, and UAE)—digital yuan must expand beyond M0 to support M1 (demand deposits) and eventually M2 (broad money). Only then can it facilitate large-scale cross-border trade and financial integration.
Why Stablecoins Matter: Three Key Roles in the Global Economy
Stablecoin market capitalization has surged from under $2 billion in 2017 to nearly $170 billion by late 2024. Though still smaller than Bitcoin and Ethereum in trading volume, stablecoins now surpass most other cryptocurrencies in utility.
They serve three pivotal functions:
- Primary trading medium in crypto markets – Over half of all Bitcoin and Ethereum trades are settled in USDT (Tether), effectively making it the de facto dollar equivalent in decentralized ecosystems.
- Liquidity provider in DeFi – Platforms use stablecoins for lending, yield farming, and automated market-making, enhancing efficiency in decentralized finance (DeFi).
- Informal reserve assets in emerging economies – In countries with weak currencies or capital controls, citizens increasingly hold stablecoins as a more stable store of value than local fiat.
This growing reliance reflects not just technological adoption but also a quiet shift in monetary behavior—especially where trust in national currencies is low.
Four Major Impacts of Stablecoins on the International Monetary System
1. Accelerating Cross-Border Payment Innovation
Traditional systems like SWIFT suffer from high costs, delays, and intermediary bottlenecks. In contrast, stablecoin-based transfers operate on public blockchains, enabling near-instant settlements without relying on correspondent banks. For remittances and trade finance, this means faster processing and lower fees—posing direct competition to legacy infrastructure.
2. Challenging Non-Dollar Sovereign Currencies
In high-inflation regions like Latin America or parts of Africa, people increasingly adopt dollar-pegged stablecoins as an alternative to depreciating local currencies. Unlike physical dollarization—which requires export earnings or foreign investment—digital dollar access is easier via gig work, online platforms, or peer-to-peer exchanges.
A telling sign? The emergence of "stablecoin premium"—where USDT trades above parity with USD—indicating strong demand and limited supply access.

3. Competing with Central Bank Digital Currencies
Nigeria’s experience illustrates this tension. After banning stablecoins in 2021 and launching its own CBDC (eNaira), adoption stalled—98.5% of eNaira was abandoned within a year. Meanwhile, crypto transaction volume grew 9%, reaching $56.7 billion between 2022 and 2023. Users preferred decentralized options for asset preservation and transfer.
Similarly, while the Biden administration prioritized a digital dollar, the Trump administration shifted toward supporting private-sector stablecoins—recognizing their real-world traction and global usability.
4. Creating Regulatory and Compliance Risks
Despite benefits, stablecoins pose serious oversight challenges:
- Anti-money laundering (AML): Mixing services can obscure fund origins using anonymized stablecoin transfers.
- Issuer transparency: Reserves backing stablecoins may lack full auditability or diversification.
- Monetary policy spillovers: Widespread dollarization via stablecoins could erode domestic control over money supply and interest rates.
Regulators must balance innovation with systemic stability—a task growing more urgent as adoption spreads.
Strategic Responses for a Multipolar Digital Monetary Order
Expand Digital Currency Functionality Beyond Cash Replacement
To boost international relevance, digital currencies like e-CNY should evolve from M0 substitutes to full-fledged transactional tools covering M1 and M2. This would unlock use in payroll, interbank clearing, securities settlement, and cross-border commerce—critical for integrating with platforms like mBridge.
Develop Platform-Based Sovereign Stablecoins
China should explore issuing regulated stablecoins tied to major tech ecosystems (e.g., Tencent, Alibaba, TikTok). By linking RMB-backed digital tokens with global user bases and digital services, these platforms could mirror Libra’s original vision—but with Chinese monetary sovereignty at its core.
Support Controlled Crypto Innovation Hubs
While mainland China maintains strict crypto regulations, special zones like Hong Kong, Hainan Free Trade Port, and the Guangdong-Hong Kong-Macao Greater Bay Area can serve as testing grounds for digital asset applications, including tokenized securities and institutional crypto custody.
Notably, even as U.S. policymakers debate Bitcoin as a strategic reserve asset, many Chinese investors already hold substantial positions—highlighting the need for clear domestic frameworks.
Promote e-SDR for a More Balanced Digital Reserve System
At the IMF level, advocating for an electronic Special Drawing Right (e-SDR) could help diversify global reserve usage in the digital age. A multi-CBDC-backed e-SDR would reduce overreliance on any single currency—including the dollar—and foster a more inclusive international monetary architecture.

Frequently Asked Questions
Q: Can stablecoins replace traditional currencies?
A: Not entirely—but they are already supplementing them in economies with weak monetary systems. In practice, they act as parallel currencies, especially for remittances and savings.
Q: Are dollar-backed stablecoins safer than other cryptocurrencies?
A: Generally yes—because they’re pegged to the USD—but risks remain around reserve transparency and regulatory enforcement. Not all stablecoins are equally backed.
Q: How do CBDCs differ from stablecoins?
A: CBDCs are issued by central banks and represent legal tender; stablecoins are typically private-sector projects backed by assets. CBDCs offer more regulatory control; stablecoins offer greater innovation speed.
Q: Could widespread stablecoin use threaten financial stability?
A: Yes—if large issuers face runs or fail audits, it could trigger liquidity crises similar to bank collapses. Regulatory oversight is essential.
Q: Is the U.S. falling behind in the digital currency race?
A: In CBDC development, possibly—but due to dominance of dollar-pegged stablecoins like USDT and USDC, the U.S. still exerts major influence through private-sector innovation.
Q: What role does blockchain play beyond cryptocurrencies?
A: Blockchain enables secure identity verification, supply chain tracking, smart contracts, and decentralized finance—all foundational for future digital economies.
