In recent years, dollar stablecoins have emerged as a transformative force in global finance, quietly reshaping cross-border payments, capital flows, and even monetary sovereignty. On July 1, Fudan University’s School of Economics hosted an online seminar titled “Stablecoins and the Great Shift in International Finance,” where Dr. Zou Chuanwei, Director of the Frontier Finance Research Center at the Shanghai Financial Development Laboratory, delivered a compelling analysis on the rise of dollar-denominated stablecoins.
Dr. Zou peeled back the layers of market hype to reveal the structural realities, risks, and geopolitical implications behind these digital assets. His insights offer a timely and data-driven perspective on how stablecoins are not just financial tools—but instruments of digital dollarization with far-reaching consequences.
The Dominance of Dollar Stablecoins: By the Numbers
Stablecoin markets have grown exponentially, now approaching $260 billion in total market capitalization. What’s more telling is their functional dominance: 97% of all cryptocurrency trading volume is conducted using stablecoins, and over 99% of those stablecoins are pegged to the U.S. dollar.

This isn’t accidental. The U.S. dollar’s entrenched role in global trade and finance has seamlessly extended into the blockchain era through stablecoins like USDT (Tether) and USDC (Circle). These tokens act as digital proxies for fiat dollars, enabling instant, borderless transactions without relying on traditional banking rails.
Yet, despite their widespread use, most stablecoins serve speculative ecosystems rather than real-world commerce. According to a recent report by Artemis, a New York-based blockchain analytics firm, less than $72.3 billion of stablecoin transaction volume in 2025 is projected to support actual economic activity—highlighting that the vast majority facilitate crypto trading and speculation.
How Stablecoins Work: A Tokenized Version of Bank Money
At their core, stablecoins are tokenized representations of commercial bank deposits, built on public blockchains such as Ethereum, TRON, Solana, and Binance Smart Chain. They operate under a simple model:
- 1:1 issuance: For every stablecoin issued, the issuer holds one dollar (or equivalent) in reserve.
- 1:1 redemption: Users can redeem stablecoins for fiat at any time.
- Reserve-backed: Reserves consist of cash, short-term U.S. Treasuries, and repurchase agreements.
This structure makes them functionally similar to money market funds, but with critical differences: they’re more accessible globally, operate 24/7, and enable peer-to-peer transfers without intermediaries.
However, this model faces a fundamental challenge—the “impossible trinity” of stablecoin design:
- Large-scale issuance
- Heavy investment in U.S. Treasury securities
- On-demand redemption
Maintaining all three simultaneously is inherently risky. If mass redemptions occur during market stress—akin to a bank run—the issuer may struggle to liquidate long-dated Treasuries quickly enough to meet withdrawal demands.
Where Stablecoins Live: Infrastructure and Distribution
The backbone of stablecoin circulation lies in public blockchains. As of mid-2025:
- Ethereum hosts 50% of all stablecoins
- TRON accounts for nearly 32%
- The remainder is spread across Solana, BSC, and Base
These networks enable fast, low-cost transactions—especially TRON, which has become a hub for high-frequency trading and remittances in emerging markets.
Despite their decentralized infrastructure, the stablecoin ecosystem remains highly centralized in issuance. USDT leads with 62% market share, followed by USDC at around 25%. Both are backed primarily by U.S. dollar assets and governed by U.S.-linked entities—giving American financial policy outsized influence over global digital liquidity.
Behind the Reserves: Transparency and Risk
Take USDC as a case study. With over $61.6 billion in circulation**, Circle maintains **$61.9 billion in reserves, slightly exceeding liabilities. These reserves are composed of:
- $28.3 billion in U.S. Treasury bills
- $25.4 billion in reverse repurchase agreements (repo)
- $80 billion in cash and cash equivalents held at U.S. banks
Notably, Circle’s Treasury holdings are extremely short-dated—none extend beyond two months (as of May 30). This strategy minimizes interest rate risk and ensures high liquidity, crucial for handling rapid redemptions.
Still, reliance on U.S. government debt ties stablecoin stability directly to the health of American fiscal policy and banking systems. Any disruption—whether a debt ceiling crisis or regional bank failure—could ripple through the entire stablecoin ecosystem.
Stablecoins as Casino Chips: The Role in Crypto Speculation
Dr. Zou draws an illuminating analogy: if the crypto market is a casino, then dollar stablecoins are the chips.
They don’t represent value themselves but serve as neutral mediums for placing bets on volatile assets like Bitcoin and Ethereum. Their stability allows traders to enter and exit positions quickly without converting back to traditional bank accounts.

Crucially, crypto prices—and by extension, stablecoin usage—are now heavily influenced by two factors:
- U.S. monetary policy (e.g., interest rates, quantitative tightening)
- U.S. regulatory developments (e.g., SEC rulings, exchange licenses)
This means that even non-American users participating in decentralized finance (DeFi) are indirectly subject to U.S. financial governance—a form of digital monetary hegemony.
Digital Dollarization: A Quiet Global Takeover
One of the most profound implications of stablecoin growth is global digital dollarization.
Over 100 million non-U.S. residents now hold dollar stablecoins—more than 29% of the U.S. population. More strikingly, over 70% of new stablecoin issuance occurs offshore, often in regions with weak currencies or capital controls.
Countries like Argentina, Nigeria, Turkey, and Vietnam have seen explosive adoption of USDT as citizens seek to preserve wealth amid inflation and currency depreciation.
This trend bypasses traditional dollar channels (like SWIFT or foreign reserves) and embeds the greenback deeper into everyday transactions—without the Federal Reserve lifting a finger.
The U.S. approach appears strategic: allow private firms to lead innovation, scale up usage globally, then step in with regulation once dominance is secured. This “launch first, regulate later” model enables soft power expansion through financial technology.
Risks to Financial Sovereignty and Stability
For countries like China, the rise of offshore dollar stablecoins poses serious challenges:
- Capital outflow risks: Individuals can easily convert RMB to USDT via peer-to-peer platforms, evading capital controls.
- Erosion of monetary autonomy: Widespread dollarization reduces effectiveness of domestic monetary policy.
- AML/CFT compliance gaps: Blockchain anonymity complicates tracking illicit flows.
Existing frameworks treat cryptocurrencies as commodities or assets—but stablecoins behave more like foreign exchange instruments. Dr. Zou argues they should be regulated accordingly: classified as foreign payment instruments, monitored for cross-border flows, and integrated into anti-money laundering systems.
Without proactive governance, nations risk losing control over their financial infrastructure to decentralized networks governed by foreign actors and algorithms.
Frequently Asked Questions (FAQ)
What exactly is a dollar stablecoin?
A dollar stablecoin is a blockchain-based digital token designed to maintain a 1:1 value with the U.S. dollar. It’s backed by reserves such as cash or short-term U.S. Treasuries and used primarily for trading, remittances, and savings in volatile economies.
Are stablecoins safer than other cryptocurrencies?
Yes—compared to volatile assets like Bitcoin or meme coins, stablecoins are far less risky because they aim to preserve value. However, they carry credit, liquidity, and regulatory risks depending on the issuer's transparency and reserve composition.
Can stablecoins replace traditional banking?
Not fully—but they’re already supplementing it in regions with underdeveloped financial systems. They offer faster, cheaper cross-border transfers and 24/7 access, but lack deposit insurance and consumer protections found in banks.
Is the U.S. government behind stablecoins?
No direct control—but U.S.-based companies issue major stablecoins (like USDC), and reserves are largely in U.S. financial instruments. This gives the U.S. indirect influence over global digital dollar flows.
Could stablecoins cause a financial crisis?
In theory, yes—if a major issuer faces a redemption rush and can’t liquidate reserves fast enough, it could trigger contagion in crypto markets and money market funds.
How can countries protect themselves from digital dollarization?
By developing central bank digital currencies (CBDCs), enforcing strict AML rules on crypto exchanges, and creating regulated local alternatives to offshore stablecoins.
