The total supply of stablecoins has recently surged to a record high of $104 billion—marking the first time it has surpassed the $100 billion threshold and representing a year-over-year increase of approximately 79% since February. Tether (USDT) dominates the market with an 85.1% share, amounting to $88 billion in circulation, followed by another major stablecoin holding a 7.2% market share. This explosive growth raises critical questions: What is driving this surge in stablecoin issuance? Is there genuine demand for so many stablecoins? And could this rapid expansion pose systemic risks to the crypto ecosystem?
To unpack these pressing concerns, we examine insights from William, Chief Researcher at OKEx Research, on the underlying mechanics, economic implications, and future outlook of today’s booming stablecoin market.
The Hidden Logic Behind Stablecoin Expansion
While many assume that increased stablecoin issuance reflects rising market demand, William argues that it's less about organic growth and more a symptom of structural flaws embedded in stablecoin design.
Most stablecoins are pegged to real-world fiat currencies like the U.S. dollar and rely on dollar-denominated reserves for backing. From an economic perspective, they must navigate what’s known as Krugman’s “Impossible Trinity”—the idea that no monetary system can simultaneously achieve all three of the following: fixed exchange rates, free capital mobility, and independent monetary policy (or controlled money supply).
In the context of stablecoins, price stability and open trading are non-negotiable. Therefore, to maintain a 1:1 peg and allow seamless conversion, issuers must sacrifice control over money supply—meaning they should not overissue beyond their reserve holdings. However, in practice, many stablecoin projects do exactly that: they issue more tokens than they have dollars in reserve.
This creates a fundamental contradiction:
- On one hand, price stability depends on trust—users believe they can redeem each token for $1 at any time.
- On the other hand, project sustainability often requires profit, which incentivizes issuing more tokens than fully backed by reserves.
As William notes, this tension makes "overissuance" (rather than neutral "issuance") a more accurate term. Stablecoin issuers aren’t charities; they need revenue to operate. But when transparency is lacking—as with Tether's historically opaque reserve audits—confidence becomes fragile.
Why Transparency Matters
Tether Ltd., the company behind USDT, has long resisted third-party audits by major accounting firms. While the firm periodically releases attestations, full transparency remains elusive. According to William, this lack of disclosure isn't accidental—it may be intentional risk management.
If Tether were to fully disclose its reserve composition and reveal significant shortfalls or risky assets (like commercial paper or loans), it could trigger a loss of confidence and a run on redemptions—similar to a bank panic.
Currently, USDT remains functional because:
- Investor concern hasn’t reached critical levels.
- Redemption mechanisms still hold.
- The scale of overissuance hasn’t yet triggered systemic collapse.
But as William warns, a tipping point may come. History shows that when trust erodes in overleveraged monetary systems—such as during the 1997 Asian Financial Crisis with the Thai baht—the fall can be sudden and devastating.
Two Worlds: Regulated vs. Unregulated Stablecoins
William emphasizes that the stablecoin market should be viewed as two distinct ecosystems:
1. Regulated & Audited Stablecoins
These include tokens like USD Coin (USDC) and Binance USD (BUSD), which undergo regular independent audits and comply with financial regulations. Their reserves are transparently disclosed and often held in safe, liquid assets like U.S. Treasuries or cash deposits.
These stablecoins represent the future of digital dollars—secure, compliant, and trusted by institutions.
2. Unregulated & Opaque Stablecoins
At the top of this category sits USDT. Despite its dominance, it operates without full regulatory approval or consistent third-party verification. Some argue its popularity stems from its flexibility in gray-market transactions, but William dismisses this notion.
“The idea that USDT thrives because it enables illicit use is misleading,” he says. “Rather, it persists because its scale hasn’t yet drawn full regulatory scrutiny.”
Once unregulated stablecoins grow large enough to threaten financial stability—or suffer a confidence crisis—they face inevitable decline: either through regulatory crackdowns or self-inflicted collapse due to reserve insufficiency.

Is Stablecoin Growth Harmful to the Industry?
William is clear: unchecked stablecoin expansion has negative long-term consequences.
He rejects the notion of a “crypto exceptionalism” where traditional economic rules don’t apply. Markets—even decentralized ones—are governed by fundamentals: supply and demand, trust, and accountability.
The unchecked growth of undercollateralized stablecoins mirrors past financial crises:
- Just as excessive credit fueled the 1997 Asian crisis,
- And just as mortgage-backed securities amplified the 2008 global crash,
- Overissued stablecoins could become the weak link in today’s crypto infrastructure.
When trust evaporates, redemption demands spike—and if reserves fall short, the peg breaks.
Moreover, widespread reliance on a single unstable anchor asset like USDT poses systemic risk. A depegging event could ripple across exchanges, lending platforms, DeFi protocols, and even impact Bitcoin and Ethereum prices.
The Path Forward: Sustainability Through Accountability
For the crypto economy to mature, stablecoins must evolve:
- Full reserve transparency via real-time attestation.
- Regulatory compliance with AML/KYC frameworks.
- Diversified collateral models, including on-chain verification and multi-currency backing.
- Decentralized alternatives, such as algorithmic or crypto-collateralized stablecoins (e.g., DAI), though these come with their own trade-offs.
Ultimately, trust cannot be assumed—it must be earned through consistency and openness.
Frequently Asked Questions (FAQ)
Q: Why does USDT dominate despite transparency concerns?
A: Network effects and liquidity drive adoption. USDT was first to market and is widely integrated across exchanges and wallets, making it convenient—even if riskier than alternatives.
Q: Can stablecoins really maintain a 1:1 peg forever?
A: Only if backed by sufficient, liquid reserves and managed transparently. Pegs break when confidence falters or redemption fails—regardless of claims.
Q: Are all stablecoins risky?
A: No. Regulated, audited stablecoins like USDC have strong safeguards. Risk varies significantly based on governance, transparency, and reserve quality.
Q: What happens if USDT loses its peg?
A: A depegging could trigger massive sell-offs, margin calls in DeFi, exchange instability, and broader market panic—similar to a flash crash but with deeper structural consequences.
Q: Is there real demand for $100+ billion in stablecoins?
A: Partly yes—for trading, hedging, remittances, and yield farming. But current supply may exceed healthy demand, especially if portions are overissued without backing.
Q: Will regulators crack down on unregulated stablecoins?
A: Increasingly likely. Governments worldwide are drafting rules targeting systemic risks posed by large-scale private digital currencies.
Final Thoughts
The surge in stablecoin issuance reflects both innovation and vulnerability. While demand for digital dollars grows alongside crypto adoption, unchecked expansion—especially without transparency—threatens stability.
The lesson is clear: sustainable growth requires accountability. The future belongs not to the biggest issuer, but to the most trustworthy one.
As the industry matures, investors should prioritize transparency, regulatory alignment, and proven reserves—not just convenience or volume. In doing so, they help build a more resilient and responsible financial ecosystem for everyone.
