Video: Terra Luna Collapse Explained: Algorithmic Stablecoin Death Spiral & Risks Date: 2022-05-09 · Type: failure · Tags: algorithmic-stablecoin, do-kwon, death-spiral, ust, luna, terraform-labs, defi, 2022 The system relied on confidence; once confidence cracked, the mechanism became the weapon Terraform Labs' UST was an algorithmic stablecoin: its peg was maintained not by collateral but by the mint-and-burn relationship between UST and the sister token LUNA. The architecture depended on the assumption that confidence would always be sufficient to close arbitrage gaps. On May 7 2022, roughly $2 billion exited Anchor Protocol, UST's primary high-yield deposit venue, breaking the peg. The protocol responded as designed, minting LUNA to absorb UST redemptions. As LUNA's price fell, the system minted more; the hyperinflation became irreversible. Within five days, LUNA had gone from roughly $80 to fractions of a cent, and UST had failed to return to its peg. Do Kwon's public posture throughout, combative, dismissive of skeptics he called "poor", made the collapse's cultural resonance sharper than its mechanics alone would have. The Luna Foundation Guard's attempt to defend the peg by liquidating ~80,000 BTC became a secondary drama with its own forensics. Kwon was arrested in Montenegro in March 2023 while traveling on a counterfeit passport, extradited to the United States in late 2024, and awaited trial as of 2025. The Terra collapse did something Mt. Gox and the DAO hack had not: it destroyed value primarily for retail participants outside the Anglophone crypto core, South Korean retail investors, Southeast Asian DeFi users, and various emerging-market participants who had treated Anchor's 20% yield as a savings account. The geography of the loss, as much as its scale, explains why it accelerated regulatory action in jurisdictions that had previously been cautious.
