In the ever-evolving world of decentralized finance (DeFi), stability is both a promise and a challenge. Recently, concerns have surfaced over USDT’s stability as liquidity imbalances emerged in Curve’s major stablecoin pool—raising questions about the resilience of one of the most widely used stablecoins in the crypto ecosystem. While panic rippled through markets, Tether’s leadership remained calm, reaffirming their ability to maintain the 1:1 peg through direct redemptions.
This article explores the technical and market dynamics behind the recent depegging event, analyzes how liquidity imbalances in DeFi protocols like Curve can impact broader market sentiment, and explains why Tether's operational strength continues to serve as a critical backstop during periods of volatility.
Understanding the Curve 3pool Imbalance
The Curve 3pool—a liquidity pool that facilitates low-slippage trading between USDT, USDC, and DAI—has long been a cornerstone of stablecoin interoperability in DeFi. However, starting on May 11, significant distortions began to appear in its composition.
At its peak imbalance, USDT accounted for approximately 91% of the total assets in the pool. This skewed ratio disrupted the intended equilibrium, leading to price discrepancies across exchanges. Traders attempting to swap USDT for USDC within the pool faced rates as low as 1 USDT = 0.96 USDC, signaling a temporary loss of parity.
Such distortions are not isolated to decentralized platforms. The ripple effects quickly reached centralized exchanges:
- Binance: USDT traded at ~$0.972
- FTX: USDT priced around $0.98
These deviations, though temporary, highlight how vulnerabilities in DeFi infrastructure can propagate across the entire digital asset market—especially during times of heightened fear or uncertainty.

Why Did This Happen? The Role of UST and Market FUD
While this incident centered on USDT, it was likely triggered by fallout from the UST depegging crisis. As UST—the algorithmic stablecoin behind the Terra ecosystem—began losing its peg, traders rushed to exit into more trusted stablecoins like USDC and DAI. This mass movement created intense selling pressure on USDT within Curve’s pools, where large volumes are swapped with minimal slippage under normal conditions.
When confidence wavers, even minor imbalances can snowball. As more users withdrew DAI and USDC from the 3pool, arbitrageurs struggled to restore equilibrium due to capital constraints and network congestion. The result? A self-reinforcing cycle of depegging and reduced liquidity.
This scenario underscores a broader truth: stablecoin stability isn’t just about reserves—it's also about trust, accessibility, and system design.
Tether’s Response: Confidence Through Redemption
Amid growing speculation, Tether’s Chief Technology Officer Paolo Ardoino projected confidence. In a series of public statements, he emphasized that the company continues to honor 1:1 redemptions without hesitation.
“FUD is making good money to few traders. Seeing firms buying USDt < $1 on Kraken, sell it for >= $1 on Finex or redeeming on [Tether] for $1.”
Ardoino noted that over $300 million worth of USDT was redeemed in the past 24 hours alone, all processed smoothly. This capability to redeem at par is a key differentiator for Tether compared to algorithmic or partially backed alternatives.
Tether’s ability to act as a stabilizing force during market stress stems from its centralized redemption mechanism—an advantage in crises but often criticized in decentralized circles.
To further support liquidity across chains, Tether coordinated with third-party operators to move $1 billion in USDT from TRC20 (Tron) to ERC20 (Ethereum)** and **$20 million from TRC20 to Avalanche. These cross-chain transfers ensure that supply remains accessible where demand spikes—without altering the total circulating supply.
This proactive asset management illustrates Tether’s operational agility in responding to real-time market needs.

Ethereum Network Congestion: A Symptom of Panic?
The broader crypto market reaction intensified network strain. As investors scrambled to convert volatile assets into stablecoins, Ethereum gas fees surged to over 800 gwei, making simple transfers cost upwards of $75.
Such congestion reflects a "flight to safety" behavior—where users prioritize security over cost efficiency. Interestingly, data from Ultrasound.money revealed that Tether transactions were among the top contributors to ETH burned in gas fees over the past 24 hours, further emphasizing the scale of activity tied to USDT movements.
While high fees are often seen as a downside, they also signal strong network usage and demand for reliable settlement layers during turbulence.
Key Takeaways: What This Means for Stablecoin Users
The recent events offer several important lessons:
- Liquidity pools are fragile under stress: Even well-established protocols like Curve can experience severe imbalances when market psychology shifts.
- Redemption matters: Tether’s ability to redeem at 1:1 provides a critical anchor during volatility—a feature many other stablecoins lack.
- Cross-chain flexibility enhances resilience: Rapid asset reallocation across blockchains helps mitigate localized supply shocks.
- DeFi and CeFi are deeply interconnected: Instability in one domain quickly spreads to others, underscoring systemic risk.
Frequently Asked Questions (FAQ)
Q: Is USDT still backed 1:1 by reserves?
A: According to Tether’s official disclosures and attestations, USDT is backed by reserves consisting of cash, cash equivalents, and other assets. Regular transparency reports aim to verify this 1:1 backing.
Q: Can I redeem USDT directly for USD?
A: Yes, accredited institutions and large holders can request redemptions directly through Tether. Retail users typically rely on exchanges to convert USDT to fiat.
Q: Why did USDT depeg if it's fully backed?
A: Backing doesn’t guarantee instant price stability. Depegs occur due to liquidity crunches, market panic, or exchange-specific supply-demand imbalances—not necessarily reserve issues.
Q: How does Curve’s design contribute to depegging risks?
A: Curve uses specialized algorithms optimized for similar-value assets. When one stablecoin loses perceived parity, the model struggles to rebalance without external arbitrage.
Q: Was this event similar to the UST collapse?
A: No. UST lost its peg due to structural flaws in its algorithmic design and reserve composition. USDT’s temporary depeg was driven by liquidity flow—not insolvency or design failure.
Q: Should I be concerned about using USDT in DeFi?
A: While short-term volatility can occur, USDT remains one of the most liquid and widely accepted stablecoins. Diversifying across multiple stablecoins may reduce exposure during extreme events.

Conclusion
The recent imbalance in Curve’s 3pool and the temporary depegging of USDT serve as a reminder that no asset is immune to market forces—even those designed for stability. However, Tether’s swift response, continued redemption capability, and strategic cross-chain operations demonstrate a level of institutional maturity that helped contain the crisis.
For investors and traders, understanding the interplay between DeFi mechanics, network effects, and centralized backstops is crucial. As the crypto economy matures, resilience will depend not only on code but also on operational transparency and responsive governance.
Stablecoins remain foundational to digital finance—but their stability is dynamic, not absolute. Staying informed and prepared is the best defense against uncertainty.
