The collapse of Terra/Luna in May 2022 was the most catastrophic event in crypto since Mt. Gox — a $60+ billion destruction of value that triggered cascading failures across the industry and forever changed how the market views algorithmic stablecoins. The story of Terra is a cautionary tale about the dangers of unsustainable yields, algorithmic hubris, and the speed at which crypto confidence can evaporate.
Terra’s mechanism: the UST stablecoin maintained its dollar peg through an algorithmic relationship with LUNA. When UST traded above $1, users could burn $1 of LUNA to mint 1 UST (increasing UST supply, pushing price down). When UST traded below $1, users could burn 1 UST to receive $1 of LUNA (decreasing UST supply, pushing price up). The system worked as long as there was demand for UST and confidence in the mechanism.
Anchor Protocol provided that demand: it offered 19.5% APY on UST deposits — an unsustainable yield funded by protocol reserves and LUNA emissions rather than real lending activity. Anchor attracted over $14 billion in deposits from users chasing the high yield, many of whom didn’t understand the risk. Do Kwon, Terra’s charismatic and combative founder, dismissed critics who called the yield unsustainable, famously telling doubters to “enjoy being poor.”
The death spiral began on May 7, 2022, when large UST sales on Curve Finance depegged UST to $0.98. The mint/burn mechanism kicked in: UST holders burned UST for LUNA, massively increasing LUNA supply. As LUNA’s price crashed from the dilution, confidence in the system collapsed. More UST holders rushed to exit, burning more UST for increasingly worthless LUNA. Within five days, UST went from $1 to $0.10, and LUNA went from $80 to fractions of a penny. $60+ billion in combined value vanished.
The cascading effects were devastating. Three Arrows Capital (3AC), which had massive LUNA and UST positions, went bankrupt — and its bankruptcy triggered the falls of Voyager Digital, Celsius Network, and Genesis Trading, as 3AC’s unpaid loans cascaded through the system. The human cost was severe: suicides were reported in South Korea, where retail investment in UST was widespread. Do Kwon became an international fugitive, eventually arrested in Montenegro in March 2023 with fake passports. He was extradited to the US in December 2024 to face fraud charges. Terra’s collapse permanently discredited purely algorithmic stablecoins and injected healthy skepticism about any protocol offering yields that seem too good to be true.
