How Stablecoins Are Disrupting Global Finance and Shaping the Future

What Is a Stablecoin and How Does It Keep Its Price Stable?

Stablecoins are crypto assets whose value is pegged to fiat currencies or a basket of assets, using three main mechanisms: fiat‑collateralized (e.g., USDT, USDC), crypto‑over‑collateralized (e.g., DAI), and algorithmic control.

Market Size and Growth

By June 2025 the total market cap of stablecoins reached US$246.3 billion, almost 50 times the 2019 level. The growth is driven by three factors: widespread adoption in crypto trading, cross‑border payments, and DeFi liquidity provision.

Key Use Cases

Trading settlement: Over 60 % of crypto trades use stablecoins for pricing and settlement.

Cross‑border remittance: Stablecoins enable fast, low‑cost transfers where traditional banking is unavailable.

DeFi liquidity: They act as the primary medium of exchange within decentralized finance protocols.

Technical Advantages

Built on blockchain, stablecoins settle in seconds, compared with 2‑4 days for SWIFT. Transaction costs are reduced by more than 90 % and the system operates 24/7.

Stablecoins as a New Player in the International Monetary System

US‑dollar‑pegged stablecoins dominate more than 90 % of the market, effectively extending dollar influence into the digital realm and adding demand for US Treasury securities. They also act as a de‑facto “hard currency” in crypto markets, reinforcing dollar network effects.

Regulators such as the U.S. GENIUS Act impose AML/KYC requirements and reserve‑backing rules, turning stablecoins into regulated financial instruments.

Stablecoins can erode sovereign monetary control: in high‑inflation economies they become preferred stores of value, and large‑scale holdings can blunt the effectiveness of domestic interest‑rate policy.

RMB Internationalization and Stablecoin Innovation

China has signed over 40 bilateral currency‑swap agreements and expanded the CIPS network, increasing RMB usage in global trade. Offshore RMB stablecoins (e.g., CNHT) and Hong Kong’s 2025 Stablecoin Ordinance provide regulatory frameworks for new issuances.

Tech firms such as JD.com have launched a JD‑HKD stablecoin, tested in Hong Kong’s sandbox, targeting B2B settlement in supply‑chain and e‑commerce scenarios.

Tech Giants’ Strategies and Competitive Landscape

Companies adopt two models: vertical integration (e.g., JD, Amazon) embedding stablecoins into their own ecosystems, and infrastructure provision (e.g., Circle’s USDC) offering neutral settlement layers.

Hong Kong serves as a regulatory hub with a tiered licensing regime, attracting firms like JD, Ant Group, and local Web3 startups.

Risks and Regulatory “Shield”

Key risks include reserve‑asset opacity, asset‑mismatch, custodial concentration, and algorithmic failure (e.g., TerraUSD). Redemption runs can trigger systemic stress, as seen with BUSD in 2023.

Regulatory responses vary: the U.S. GENIUS Act, the EU’s MiCA framework, and Hong Kong’s “same‑risk‑same‑regulation” approach impose reserve‑backing, licensing, and AML/KYC obligations.

Future Outlook for Stablecoins

In the next 1‑3 years, clearer regulation, market segmentation, and deeper tech integration will drive adoption. Dollar‑pegged stablecoins may lose share to euro, HKD, and SGD issuances, while niche vertical stablecoins emerge for gaming and supply‑chain finance.

Beyond 2028, a layered monetary architecture could appear: CBDC at the top, bank money in the middle, and stablecoins at the base, enabling ultra‑fast cross‑border payments and new hybrid financial products.

Long‑term, stablecoins may reshape global monetary sovereignty, foster financial inclusion for the unbanked, and prompt “embedded regulation” via smart‑contract enforcement.

Conclusion

Stablecoins offer powerful efficiency gains but also pose significant regulatory and systemic risks. Their evolution will depend on balanced innovation, robust oversight, and alignment with public‑interest goals.
