Global Stablecoin Trends and Policy Evolution in 2025

The global financial landscape is undergoing a transformative shift, with stablecoins emerging as pivotal instruments bridging traditional finance and the digital asset ecosystem. On June 21, 2025, the Renmin University of China Shenzhen Research Institute hosted the 62nd "RUC Shenzhen Social Science Salon" and the 256th "Macro-Finance Thought Salon," focusing on “Global Stablecoin Trends and Policy Evolution.” Zhu Taihui, Senior Research Fellow at the National Institution for Finance and Development, delivered a comprehensive keynote on stablecoin business models, impacts, and regulatory frameworks.

This article explores the evolving role of stablecoins in the global monetary system, analyzing their operational mechanics, real-world applications, macroeconomic implications, and regulatory developments.

Understanding Stablecoin Business Models and Key Debates

The Functional Nature of Stablecoins: A Tiered View

Stablecoins must be understood within the broader context of the “crypto asset pyramid,” which includes central bank digital currencies (CBDCs), stablecoins, tokenized real-world assets (RWA), and volatile cryptocurrencies like Bitcoin. At the top—CBDCs—value is tightly linked to sovereign fiat. As we move down, reliance on external value backing diminishes, and price volatility increases.

Stablecoins occupy a strategic middle ground: they combine the decentralized efficiency, programmability, and speed of blockchain technology with the price stability of fiat currencies. Currently, stablecoins represent about 7.5% of total crypto market capitalization, serving as a critical on-ramp between crypto markets and traditional finance.

They offer mutual benefits across stakeholders:

• Issuers earn investment returns from reserve assets.
• Users enjoy faster, cheaper cross-border payments.
• Holders in high-inflation economies gain a store of value.
• Crypto investors use stablecoins as exit liquidity.

There are four primary types: fiat-backed, crypto-collateralized, commodity-backed, and algorithmic. However, fiat-backed stablecoins dominate, accounting for over 95% of the market.

Are Stablecoins Truly Decentralized?

Despite being issued on decentralized blockchains, stablecoins are not fully decentralized in practice. Their issuance, custody, and redemption processes remain centralized.

Take USDT as an example:

1. Users deposit fiat into Tether’s bank accounts.
2. Tether mints USDT 1:1 and invests reserves.
3. Users trade USDT peer-to-peer.
4. To redeem, users return USDT to Tether.
5. Tether destroys the tokens and returns fiat.

In this model:

• Issuance and custody are centralized.
• Trading is partially decentralized.
• Reserve investment income is the primary revenue source—Circle earned 99% of its 2024 revenue from USDC reserve yields.

This structure blurs lines between traditional financial intermediaries and digital asset providers.

Clarifying Common Misconceptions

Several debates persist about stablecoins’ true nature:

• Are they just a new form of money?
• Are they digital payment tools?
• Do they resemble money market funds?
• Are issuers capturing seigniorage?
• Do they threaten monetary sovereignty?

The answer lies in recognizing stablecoins as a hybrid instrument: they leverage crypto infrastructure, enable digital payments, and maintain value like money market funds—but crucially:

• They do not create new money; they tokenize existing fiat.
• They do not share seigniorage; value stability comes from reserves.
• Investment returns go to issuers, not holders.
• They function as regulated digital payment tools, not sovereign currencies.

Use Cases and Emerging Trends in Stablecoin Adoption

1. Rapid Market Expansion

Stablecoin market capitalization has surged to $261.5 billion** as of June 2025 (with $253.3 billion in USD-pegged variants). Over 616 million active wallets now exist globally. According to Citigroup, stablecoin value could reach $1.6 trillion by 2030** under baseline assumptions—and up to **$3.7 trillion** in optimistic scenarios.

2. Mainstream Payment Integration

Originally used for crypto trading settlements, stablecoins are now entering everyday commerce. Transaction sizes are shrinking:

• 12-month average: $4,560
• 3-month average: $4,260
• 1-month average: $3,380

This trend signals a shift toward small-scale cross-border trade and retail payments.

Visa’s 2024 survey across Brazil, India, Indonesia, Nigeria, and Turkey found stablecoins used for:

• Currency substitution
• Goods and services payments
• Cross-border remittances
• Salary disbursements

Fireblocks reports that payment firms’ share of stablecoin volume will rise from 16% to 50% within a year. Retail giants like Walmart and Amazon are reportedly exploring proprietary stablecoins.

3. Growing Demand for Compliance

Regulatory clarity is accelerating worldwide. Jurisdictions like the EU, Singapore, UAE, and Hong Kong have enacted stablecoin laws. In 2025, over 20 countries—including the UK, South Korea, Australia, and Turkey—advanced legislative proposals.

Market preference is shifting toward compliant issuers:

• USDC’s market share rose from 20% to 25%
• USDT’s dropped from 70% to 64%

Transparency and regulatory adherence are now key competitive advantages.

4. Convergence with Traditional Finance

Three major integration trends are evident:

1. Merchants adopting stablecoin payments: USDT is used in UAE real estate and oil trades; Singapore’s Meidi-Ya and SPAR accept crypto payments.
2. Payment platforms launching stablecoin services: PayPal and Stripe offer stablecoin transactions; Visa and Mastercard partner with Kraken, OKX, and Crypto.com for daily spending.
3. Banks issuing stablecoins: JPMorgan upgraded JPM Coin to Kinexys for institutional cross-border settlements. Bank of America, Citi, and Wells Fargo are discussing joint stablecoin initiatives.

A May 2025 Fireblocks report revealed that 90% of financial institutions are deploying or planning to deploy stablecoins.

5. Accelerating Real-World Asset Tokenization (RWA)

RWA is still nascent—valued at just over **$24 billion** with ~190 issuers—but growing rapidly (+260% YoY). BlackRock’s tokenized U.S. Treasury fund via Securitize hit $1 billion in on-chain volume by March 2025, offering daily dividends.

Tokenization reduces costs, speeds settlement, and enhances transparency—making it a natural extension of stablecoin infrastructure.

Impact on the Global Monetary System

The Rise of a “New Dollar Cycle”

Dollar-backed stablecoins dominate:

• 95%+ of stablecoins are fiat-backed
• Of those, 95–99% are USD-denominated
• USDT and USDC together account for ~90% of market cap

This dominance exceeds the dollar’s role in global finance:

• Foreign reserves: 57.8%
• International payments: 49.1%

Critically, most stablecoin reserves are invested in U.S. Treasuries:

• Tether holds ~$120B in U.S. government securities (80% of reserves)
• Circle holds ~$55.5B in U.S. Treasuries (92% of reserves)

This creates a self-reinforcing “new dollar cycle”:

Fiat USD → Buy USD stablecoins → Use in global transactions → Reserves reinvested in U.S. assets → Capital flows back to America

Citigroup projects that by 2030, stablecoin holdings of U.S. debt could exceed $1.2 trillion, surpassing any single foreign holder.

U.S. policy reflects this strategic vision:

• The January 2025 executive order promotes dollar-backed stablecoins.
• The Genius Act mandates reserve investments in U.S. financial products and restricts foreign issuers.

A Path Forward for Offshore RMB Stablecoins

While RMB’s international presence lags behind China’s trade volume (3.75% in payments vs. 14.6% exports), offshore RMB stablecoins offer a strategic opportunity.

Hong Kong’s Aurum project demonstrated how CBDCs and stablecoins can coexist: using CBDC as backing for privately issued stablecoins in a hybrid model.

China should adopt a gradual, controlled approach:

1. Launch first in Hong Kong—leveraging its financial infrastructure.
2. Expand gradually to free trade zones.
3. Anchor only to RMB to protect monetary sovereignty.
4. Start with trade settlements using smart contracts.
5. Limit early access to qualified investors.

This phased model balances innovation with control.

Global Regulatory Framework: The Five-Pillar Model

1. Clear Functional Boundaries

Most regulators support only fiat-backed stablecoins for payments. Algorithmic variants are largely excluded due to volatility risks.

Usage rules vary:

• Open economies (Singapore, Hong Kong): allow both local and foreign stablecoins.
• Larger blocs (EU, UAE): restrict foreign stablecoins to protect monetary sovereignty.
• The EU caps daily transaction volumes to avoid destabilizing banks.

2. Licensing Requirements

Stablecoin issuers must obtain licenses—often allowing banks to issue them under supervision. Issuers cannot:

• Pay interest on holdings
• Offer lending services

This aligns them with third-party payment providers rather than banks.

3. Operational Oversight

Regulators apply the principle: “same activity, same risk, same rules.” Requirements include:

• Capital adequacy
• Liquidity buffers
• Risk management systems

Local presence is mandatory for oversight purposes.

4. Reserve Management Transparency

Key safeguards include:

• Independent audits by licensed firms
• Full backing in equivalent-currency assets
• Investments limited to high-grade instruments (e.g., Treasuries)
• Clear redemption timelines
• Priority payout during insolvency

5. Anti-Money Laundering (AML) Enforcement

Due to blockchain’s pseudonymity and global reach, AML is critical. Most nations follow FATF guidelines:

• Apply “Travel Rule” for transactions over $1,000
• Require sender/receiver data to accompany transfers
• Extend banking-level AML/CFT rules to exchanges and issuers

Looking Ahead: Three Critical Questions

1. Can traditional regulatory models adapt to decentralized systems long-term?
2. Should regulators adopt blockchain-based “embedded supervision”?
3. How can national regulators address the mismatch between global crypto activity and domestic governance?

Frequently Asked Questions (FAQ)

Q: What are the main types of stablecoins?
A: The four main types are fiat-backed (e.g., USDT), crypto-collateralized (e.g., DAI), commodity-backed (e.g., gold), and algorithmic (no collateral). Fiat-backed versions dominate due to their stability and transparency.

Q: Why are USD-backed stablecoins so dominant?
A: The U.S. dollar’s global reserve status, deep capital markets, and strong institutional trust make it ideal for backing digital assets. Additionally, most crypto trading pairs are USD-based.

Q: Can stablecoins replace traditional currencies?
A: Not currently. Stablecoins are digital representations of fiat—they don’t create new money or replace central bank functions. Their role is complementary, enhancing payment efficiency rather than challenging sovereignty.

Q: Are stablecoins safe for everyday use?
A: Compliant fiat-backed stablecoins with transparent reserves (like USDC) are generally safe. However, users should verify issuer credibility and understand redemption mechanisms before use.

Q: How do regulators prevent stablecoin misuse?
A: Through licensing, reserve audits, AML checks (including Travel Rule compliance), usage restrictions, and capital requirements—mirroring frameworks used for banks and payment processors.

Q: Could China launch its own RMB stablecoin?
A: Yes—especially through a phased offshore rollout starting in Hong Kong. Such a move could enhance RMB internationalization while maintaining control over monetary policy and financial stability.
