While Terra’s UST stablecoin collapsed in spectacular fashion, the cryptocurrency market’s most important infrastructure asset — tether (USDT) — faced its own existential crisis and survived. The world’s largest stablecoin lost its dollar peg briefly on May 12, 2022, plunging to as low as 95 cents before staging a full recovery by May 13. The episode tested the very foundations of the stablecoin market and, against expectations, tether passed.
The distinction between tether’s performance and UST’s total collapse could not have been more stark. On the same day that Luna plunged to zero and UST traded at 12 cents, tether processed more than $3 billion in withdrawals — one of the largest single-day redemption events in stablecoin history — and still maintained its peg by Friday morning.
TL;DR
- Tether (USDT) briefly dropped to $0.95 on May 12 amid broader stablecoin panic
- By May 13, USDT fully regained its $1.00 peg
- The company processed over $3 billion in withdrawals within 24 hours
- Unlike UST, tether is backed by real-world reserve assets
- Bitcoin rebounded above $30,000 as tether stabilized, calming market fears
Contagion From Terra Spreads to Tether
The panic that engulfed Terra’s ecosystem inevitably spilled over to tether. After UST lost its dollar peg on May 9, fear spread rapidly across the stablecoin market. Investors questioned whether all stablecoins — regardless of their backing mechanism — might be vulnerable to the same kind of run that destroyed UST.
Tether, with a market capitalization of approximately $83 billion at the time, is the single most important piece of plumbing in the cryptocurrency ecosystem. It serves as the primary medium of exchange on most major crypto exchanges and is deeply embedded in DeFi protocols. A failure of tether would have been orders of magnitude more destructive than the Terra collapse.
On Thursday, May 12, that fear manifested in a sharp depegging event. USDT dropped to 95 cents on several exchanges as panicked investors sold their tether holdings at a discount. The 24-hour trading volume for USDT spiked to approximately $87 billion — more than its entire market capitalization — reflecting the intensity of the panic-driven trading.
Tether Proves Its Reserves Matter
The critical difference between tether and UST came down to reserves. Unlike UST, which relied on an algorithmic mechanism tied to Luna to maintain its peg, tether is backed by a portfolio of real-world assets including U.S. Treasury bills, corporate bonds, and other traditional financial instruments. When redemption requests flooded in, tether had actual assets to sell.
Tether’s parent company announced that it had processed more than $3 billion in redemptions — and did so “pretty quickly,” according to company statements. The ability to honor redemptions at par value, even under extreme stress, proved to be the market that tether’s reserves were real and accessible.
By Friday, May 13, tether was trading firmly at $1.00 again. The recovery provided a crucial signal to the broader market that the stablecoin infrastructure was intact. Bitcoin, which had fallen to a 90-day low of $26,350 on Thursday, rebounded above $30,000 on Friday — a move that coincided closely with tether’s return to its peg.
A Tale of Two Stablecoins
The divergent fates of UST and tether during the same week serve as a defining case study in stablecoin design. Both lost their pegs under market stress. The difference was in what happened next.
UST, backed only by algorithmic code and its connection to Luna, entered a death spiral from which there was no recovery. As selling pressure mounted, the protocol minted ever more Luna tokens to absorb UST selling, hyperinflating the Luna supply and driving its price to zero. The mechanism that was supposed to maintain stability became the instrument of destruction.
Tether, by contrast, faced a conventional bank-run scenario — and survived it the way traditional financial institutions do, by having sufficient liquid reserves to meet withdrawal demands. The $3 billion redemption test was arguably the most important stress test tether had faced since its launch in 2014, and the outcome validated the reserve-backed model.
Implications for the Stablecoin Market
The week’s events had immediate consequences for the stablecoin landscape. The total stablecoin market cap contracted significantly as billions flowed out of the system. Market confidence shifted decisively toward reserve-backed stablecoins like tether and USDC, while algorithmic alternatives faced deep skepticism that persists to this day.
Regulators around the world took notice. The Terra collapse and the brief tether depegging intensified conversations in Washington and other global financial centers about the need for stablecoin regulation. Treasury Secretary Janet Yellen cited the Terra episode specifically when calling for a federal regulatory framework for stablecoins by the end of 2022.
For crypto traders and DeFi users, the lesson was clear: not all stablecoins are created equal. The peg is only as strong as what backs it, and in a crisis, reserves beat algorithms every time.
Why This Matters
Tether’s survival during the Terra crisis was arguably the most important non-event in crypto history. Had tether failed — had the $83 billion stablecoin been unable to process redemptions — the cascading effects would have devastated the entire cryptocurrency market far beyond what the Terra collapse alone caused. Tether is the backbone of crypto trading pairs, DeFi liquidity pools, and cross-exchange settlement. Its successful stress test at $3 billion in daily redemptions proved that reserve-backed stablecoins can withstand extreme market conditions. This event solidified tether’s dominant position and accelerated the industry’s move away from algorithmic stablecoins toward transparent, asset-backed alternatives.

$3 billion in redemptions in 24 hours and tether still held. say what you want about their reserves but they passed the stress test
if tether had failed on top of UST the entire crypto market would have gone dark. we got lucky
agree. an $83 billion stablecoin collapsing would have made the Luna crash look like a speed bump
the fact that USDT dropped to 95 cents because of UST panic shows how irrational this market gets. completely different assets
