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.
