Stablecoins have rapidly evolved from a niche innovation in the cryptocurrency space into a transformative force with the potential to redefine global finance. As digital currencies pegged to stable assets like fiat money or short-term securities, they offer the benefits of blockchain technology—speed, transparency, and decentralization—without the extreme volatility associated with cryptocurrencies like Bitcoin. With recent regulatory momentum in key financial hubs such as the U.S. and Hong Kong, including proposals like the U.S. GENIUS Act and Hong Kong’s new Stablecoin Ordinance, stablecoins are stepping into the mainstream spotlight.
This article explores how stablecoin adoption could influence the future of global monetary systems, examining growth drivers, systemic risks, and long-term implications for major currencies—including the U.S. dollar, euro, yen, and renminbi.
The Rise of Stablecoins: From Niche to Global Infrastructure
Stablecoins are digital tokens designed to maintain a stable value by being backed by reserve assets such as fiat currencies (e.g., U.S. dollars), government securities, or commodity baskets. Unlike traditional cryptocurrencies, their price stability makes them ideal for everyday transactions, remittances, and as a store of value in volatile economies.
Since the emergence of decentralized finance (DeFi) around 2020, the stablecoin market has grown exponentially—from just $5 billion in market capitalization to over **$250 billion today. Annual transaction volumes now approach $37 trillion, highlighting their increasing role in on-chain economic activity. Notably, more than 95% of all stablecoins are USD-backed**, reinforcing the dollar’s dominance in digital finance.

Projections suggest this trend will accelerate. Conservative estimates indicate that stablecoin market size could reach $4 trillion by 2035, representing a compound annual growth rate (CAGR) of over 30%. In an optimistic scenario outlined by U.S. Treasury Secretary Scott Bessent, that milestone could be achieved as early as 2029, implying a staggering CAGR above 80%.
Moreover, stablecoins’ share of global off-chain settlement value—which currently stands at about 0.4%—could rise to 3–4% within a decade. This shift would mark a fundamental change in how cross-border payments and financial intermediation operate.
Key Drivers Behind Stablecoin Growth
Several interrelated factors are fueling this expansion:
- Advancements in distributed ledger technology have enabled faster, more secure, and transparent transaction processing.
- High-efficiency payments, especially across borders, outperform traditional banking rails in speed and cost.
- Financial inclusion: Stablecoins can function without requiring bank accounts, offering access to populations in underbanked regions.
- Bypassing legacy systems: By circumventing SWIFT and correspondent banking networks, stablecoins reduce reliance on centralized financial infrastructure.
- Monetary incentives for issuers: Entities issuing stablecoins can earn yield on reserve assets—such as short-term Treasuries—creating a profitable business model.
Regulatory clarity, such as that proposed under the GENIUS Act and Hong Kong’s emerging framework, is expected to enhance trust and security while preserving innovation—striking a crucial balance between efficiency and risk management.
Implications for Global Monetary Policy and Financial Stability
While stablecoins offer clear advantages, their growing integration into global finance raises important questions about monetary sovereignty, credit creation, and systemic risk.
Credit Expansion and the "Shadow Banking" Effect
Although stablecoins are not officially recognized as narrow money issued by central banks, certain designs may mimic aspects of credit creation. If reserve portfolios include interest-bearing instruments like government bonds or commercial paper—rather than solely cash equivalents—stablecoin issuance can effectively generate new liquidity outside traditional banking channels.
This resembles the dynamics of shadow banking, where non-bank entities create credit-like instruments that expand the effective money supply. If central banks fail to account for this in monetary aggregates or adjust policy accordingly, it could lead to unintended loosening of financial conditions.
For example, under the GENIUS Act framework, U.S. dollar stablecoins would be required to hold reserves in cash, short-term Treasuries, and certificates of deposit. Widespread adoption could significantly increase demand for short-dated U.S. debt, potentially depressing yields and distorting the yield curve—making it steeper than fundamentals would justify.
Additionally, if large-scale migration occurs from bank deposits to stablecoin reserves, commercial banks might face reduced funding availability. This could diminish the Federal Reserve’s ability to influence credit markets through interest-on-reserves policies and indirectly contribute to higher inflationary pressures if unchecked.
Long-Term Risks: Liquidity Crises and "Runs" on Reserves
Even with robust reserve requirements, stablecoins remain vulnerable to liquidity shocks. Should confidence erode—due to perceived reserve insufficiency, geopolitical tensions, or macroeconomic stress—users might rush to redeem tokens simultaneously.
Such a "run" could strain issuers’ ability to liquidate underlying assets quickly, especially if those assets include less liquid bonds or private credit instruments. While major players like USDC and DAI maintain high transparency and audit standards, broader market fragility remains a concern.
Ultimately, the risk premium embedded in reserve assets—particularly U.S. Treasuries—will reflect long-term fiscal realities: America’s budget deficits, debt sustainability, and external account imbalances. Any deterioration in these fundamentals could trigger renewed volatility in stablecoin ecosystems.
The Path Forward for Non-Dollar Stablecoins: Hong Kong, Euro, and RMB
Currently dominated by dollar-pegged tokens, the stablecoin landscape may diversify over time due to network effects and geopolitical shifts.
Hong Kong’s Strategic Opportunity
Hong Kong is uniquely positioned to develop a credible Hong Kong dollar (HKD)-backed stablecoin. Given its currency peg to the U.S. dollar, success hinges on building a deep pool of high-quality, liquid reserve assets beyond just HKD cash—particularly local-currency-denominated fixed-income instruments.
Expanding this asset base strengthens resilience and reduces dependency on offshore liquidity. Moreover, as part of broader efforts toward de-dollarization, Hong Kong could also support the development of offshore renminbi (RMB) stablecoins, facilitating trade and investment flows with mainland China and Belt and Road partners.
To succeed, Hong Kong must:
- Strengthen regulatory oversight of stablecoin issuers
- Promote use cases in cross-border commerce and digital identity
- Foster collaboration between fintechs, banks, and public-sector entities
- Integrate stablecoins into emerging digital economy frameworks

Frequently Asked Questions (FAQ)
Q: What exactly is a stablecoin?
A: A stablecoin is a type of cryptocurrency designed to maintain a stable value by being backed by reserves such as fiat currency (like the U.S. dollar), commodities, or financial instruments.
Q: Are stablecoins regulated?
A: Regulation varies by jurisdiction. The U.S. GENIUS Act and Hong Kong’s Stablecoin Ordinance represent moves toward comprehensive oversight, requiring transparency, licensing, and strict reserve management.
Q: Can stablecoins replace traditional money?
A: Not fully yet—but they’re increasingly used for payments, remittances, and DeFi applications. Their role may expand as infrastructure and trust grow.
Q: What happens if a stablecoin "loses its peg"?
A: If confidence collapses or reserves are insufficient, a stablecoin may trade below its intended value (e.g., $0.90 instead of $1.00). This "de-pegging" event can trigger sell-offs and redemption pressure.
Q: Do stablecoins earn interest?
A: While holding stablecoins doesn’t directly pay interest, users can lend or stake them in DeFi protocols to earn yields. Issuers also earn returns on reserve assets.
Q: Could stablecoins cause inflation?
A: Indirectly—yes. If stablecoin issuance expands liquidity without central bank control and isn't offset by monetary tightening, it could contribute to inflationary pressures.
Conclusion: A New Chapter in Global Finance
Stablecoins are no longer just tools for crypto traders—they are becoming integral components of the global financial architecture. With exponential growth projected over the next decade, they stand to reshape payment systems, challenge monetary policy frameworks, and offer alternative paths for currency internationalization.
