The Terra/LUNA collapse of May 2022 stands as the most catastrophic event in cryptocurrency history by destruction of value in a short time period. In just 72 hours, TerraUSD (UST) — a $20 billion algorithmic stablecoin — lost its dollar peg and collapsed to zero. The related LUNA token, once trading near $120, became worthless. Combined, the collapse erased $60 billion in market value and triggered a contagion that spread throughout the entire crypto industry.
What Was Terra and How Did It Work?
Terra was a blockchain built by Terraform Labs (founded by Do Kwon and Daniel Shin) that hosted the UST stablecoin. Unlike collateralized stablecoins (USDC, USDT backed by real dollars) or overcollateralized stablecoins (DAI backed by more crypto than issued), UST was 'algorithmic' — its peg was maintained purely through economic incentives involving the LUNA token.
The mechanism: 1 UST could always be minted by burning $1 worth of LUNA, and 1 UST could always be redeemed for $1 worth of LUNA. This arbitrage mechanism was supposed to maintain the peg. If UST fell below $1, arbitrageurs would buy cheap UST and burn it for $1 of LUNA (profit), reducing UST supply and restoring the peg. If UST rose above $1, they'd burn LUNA to mint UST (profit), increasing supply.
The fatal flaw: this mechanism only works if confidence in the system holds. If too many people try to exit UST simultaneously, the mint/burn mechanism creates a 'death spiral' — burning UST creates more LUNA, which dilutes LUNA's value, which reduces confidence in UST further, which creates more UST redemptions.
- ✓UST: algorithmic stablecoin, peg maintained by LUNA mint/burn mechanism
- ✓No real dollar collateral: peg relied entirely on market confidence
- ✓Anchor Protocol: offered 20% APY on UST deposits, unsustainable
- ✓Do Kwon: co-founder, famously dismissive of critics ('I love watching lunatics')
- ✓Luna Foundation Guard: held $3.5B Bitcoin reserve to defend UST peg
- ✓Peak UST market cap: ~$19 billion; Peak LUNA market cap: ~$40 billion
The Attack: How the Depeg Was Triggered
On May 7, 2022, large coordinated withdrawals from Anchor Protocol (where $14 billion in UST was deposited earning 20% APY) began. Simultaneously, a large entity shorted LUNA and sold $350M in UST on Curve Finance's 3pool, pushing UST slightly off peg to $0.99.
The slight depeg triggered a panic — retail investors who had relied on Anchor's 20% yield began withdrawing en masse. Do Kwon and the Luna Foundation Guard deployed their $3.5 billion Bitcoin reserve to buy UST and defend the peg, but the selling pressure overwhelmed the defense. Bitcoin reserves were depleted while the peg continued to fall.
As UST fell further off peg, LUNA was minted in massive quantities to meet redemptions — hyperinflation of LUNA. LUNA's supply increased from 350 million to 6.5 trillion tokens in days. With supply expanding at this speed, LUNA's price crashed from $80 to fractions of a cent. The mechanism meant to save UST instead destroyed it.
- ✓Initial depeg: $350M UST sold on Curve — UST fell to $0.985
- ✓Anchor withdrawal: $14B in UST began leaving 20% APY vaults
- ✓Luna Foundation Guard: deployed $3.5B Bitcoin — overwhelmed by selling
- ✓LUNA hyperinflation: supply grew from 350M to 6.5 trillion in days
- ✓UST price: $1.00 → $0.10 → $0.01 → $0.0001 in 72 hours
- ✓LUNA price: $80 → $0.0001 in 72 hours
The Contagion: Firms That Fell After Terra
Three Arrows Capital (3AC), a Singapore-based hedge fund with $18 billion AUM, had massive exposure to LUNA and UST. The collapse wiped out their positions and revealed overleveraged bets across their entire portfolio. 3AC defaulted on loans to multiple counterparties and filed for bankruptcy in June 2022, triggering losses at dozens of firms.
Voyager Digital had lent $650M to 3AC. When 3AC defaulted, Voyager was unable to meet customer withdrawals and filed for bankruptcy in July 2022. Celsius Network, a crypto lending platform with $25 billion in user assets, had also experienced losses from LUNA and from 3AC exposure. Celsius froze withdrawals in June 2022 and filed for bankruptcy.
The cascading bankruptcies destroyed billions in user funds across multiple platforms and triggered a prolonged crypto bear market lasting through 2022. Bitcoin fell from $47,000 in March 2022 to $15,500 by November 2022 — the worst bear market in crypto history by duration and severity.
- ✓3AC (Three Arrows Capital): $18B hedge fund, LUNA exposure → bankruptcy June 2022
- ✓Voyager Digital: $650M loan to 3AC defaulted → bankruptcy July 2022
- ✓Celsius Network: $25B platform, LUNA + 3AC losses → froze withdrawals June 2022
- ✓BlockFi: further weakened, eventually collapsed with FTX
- ✓Bitcoin: fell from $47K (March 2022) to $15.5K (November 2022)
- ✓Total industry loss: $2 trillion in market cap from peak to trough 2021–2022
Do Kwon's Arrest and Legal Consequences
After the collapse, Do Kwon launched Terra 2.0 (LUNA Classic renamed to LUNC, new LUNA token created). The relaunch was widely criticized as an attempt to profit from a second token after destroying the first. Most major exchanges listed LUNA 2.0 but the new token never recovered meaningful market cap.
Do Kwon was indicted in the United States and South Korea on fraud charges. He fled to Dubai, then to Serbia. Interpol issued a red notice for his arrest. He was arrested in Montenegro in March 2023 while attempting to board a flight with forged travel documents.
After a year of extradition battles, Do Kwon was extradited to the United States in 2024 to face federal fraud charges. He faces up to 130 years in prison if convicted on all counts. The case is ongoing as of 2026.
- ✓Terra 2.0 launch: new LUNA token created, widely seen as opportunistic
- ✓Do Kwon indicted: US and South Korea charges for fraud
- ✓Arrested in Montenegro: March 2023, caught with forged documents
- ✓Extradited to USA: 2024 for federal fraud trial
- ✓Potential sentence: 130 years if convicted on all counts
- ✓LFG (Luna Foundation Guard) still holds assets disputed in bankruptcy proceedings
