In the wake of the dramatic collapse of TerraUSD (UST), the third-largest stablecoin, global markets witnessed a moment of panic that briefly shook confidence in the entire stablecoin ecosystem. On Thursday, Tether (USDT), the world’s largest stablecoin by market capitalization, saw its value dip to as low as $0.9455—its weakest level since December 2020—sparking fears of a broader de-pegging event.
However, swift action from Tether’s leadership and strong underlying fundamentals quickly restored stability. The episode highlighted critical differences between algorithmic and reserve-backed stablecoins—and reaffirmed why USDT remains a cornerstone of the digital asset economy.
Why USDT Briefly Lost Its Peg
The turmoil began with the failure of UST, an algorithmic stablecoin designed to maintain a 1:1 peg with the U.S. dollar through complex mechanisms involving its sister token, Luna. As confidence evaporated, UST plunged below $0.13, dragging Luna’s value down with it—from over $119 just weeks earlier to fractions of a cent.
This contagion spilled over into USDT, triggering sell-offs and redemption surges across exchanges. At its lowest point, USDT traded at $0.9455, raising alarm among traders and retail investors alike.
“Fear was spreading rapidly,” said Paolo Ardoino, Chief Technology Officer at Tether. “There was confusion in the market—some people were conflating UST with USDT, which are fundamentally different products.”

Key Differences Between USDT and UST
To quell growing anxiety, Ardoino joined a live Twitter Space discussion with cryptocurrency pioneers Samson Mow and Adam Back, where he outlined the structural advantages that set USDT apart from failed algorithmic models like UST.
Reserve-Backed vs. Algorithmic Design
The most crucial distinction lies in their design philosophy:
- UST relied on algorithmic mechanisms and incentives to maintain its peg, partially backed by a volatile reserve of Bitcoin.
- USDT, by contrast, is backed by a diversified portfolio of assets, with more than half held in short-duration U.S. Treasury bills.
This means that when users request redemptions, Tether can liquidate high-quality, liquid assets quickly—without relying on market confidence or speculative token dynamics.
“We’ve already processed $6 billion in redemptions over the past 24 hours,” Ardoino confirmed. “Our reserves are more than sufficient to meet demand.”
Real-World Utility and Adoption
Another key factor is utility. While UST was primarily used within decentralized finance (DeFi) protocols to earn high yields—sometimes up to 20% annually—its real-world use cases were limited.
USDT, on the other hand, is widely accepted for everyday transactions—from buying groceries to purchasing real estate in certain jurisdictions. Its integration across payment platforms, remittance services, and global exchanges underscores its role as a functional digital dollar.
“USDT has real-world use cases that others simply don’t,” said Samson Mow during the discussion. “That creates intrinsic demand beyond speculation.”
Redemption Mechanism Remains Intact
Despite receiving an unprecedented $2 billion in redemption requests following the UST crash, Tether confirmed that all redemptions were processed at par value via bank wire.
“USDT did not de-peg because the system worked exactly as designed,” Ardoino emphasized. “We have the liquidity to honor every single redemption request.”
CryptoCompare data shows that approximately half of all Bitcoin transactions are settled using USDT, underscoring its systemic importance in the crypto economy. With a current market cap exceeding $80 billion, USDT dwarfs UST’s peak size and maintains deep liquidity across major trading pairs.
Lessons Learned: Stability Through Transparency and Prudent Management
The crisis exposed a critical vulnerability in fast-growing algorithmic stablecoins: scalability without adequate risk management leads to fragility.
Ardoino pointed out that UST’s rapid expansion—without sufficient collateral or stress-tested mechanisms—made it vulnerable to panic-driven runs.
“Growth is good—but not at the expense of resilience,” he said.
Tether has faced scrutiny in the past over transparency concerns, but recent attestations and regular reserve disclosures have improved trust. The company now publishes monthly reserve reports verified by independent firms, showing consistent backing of issued tokens.

Frequently Asked Questions (FAQ)
Is USDT still pegged to the U.S. dollar?
Yes. After a brief dip during market turmoil, USDT has stabilized back at its $1.00 peg across major exchanges due to robust redemption mechanisms and strong reserve backing.
Can I redeem USDT for real dollars?
Yes. Eligible institutions and users can redeem USDT directly through Tether for U.S. dollars via bank transfer at a 1:1 ratio, subject to verification and compliance checks.
What backs USDT?
As of the latest report, USDT reserves consist primarily of cash and cash equivalents, including over 50% in short-term U.S. Treasury securities, along with secured loans and other highly liquid assets.
Why didn’t USDT collapse like UST?
Because USDT is fully collateralized with real-world assets, unlike UST, which relied on algorithms and investor confidence. This allows Tether to meet redemptions even under extreme pressure.
Should I be worried about holding USDT?
For most users, especially those engaged in trading or cross-border payments, USDT remains one of the most reliable and widely accepted stablecoins. Continuous reserve audits enhance long-term confidence.
How does market volatility affect stablecoins?
Even well-backed stablecoins can experience temporary price fluctuations due to trading imbalances or panic selling. However, strong redemption systems and deep liquidity typically restore the peg quickly.
The Road Ahead: Trust Through Resilience
While the recent episode tested market nerves, it ultimately demonstrated the strength of reserve-backed stablecoins like USDT in times of crisis. Unlike purely algorithmic models that depend on fragile incentive structures, USDT’s reliance on tangible assets provides a critical buffer against volatility.
As regulatory scrutiny increases and institutional adoption grows, transparency and solvency will become even more vital for stablecoin operators.
