## Terra's Rise and Design

Launched in 2018, Terra combined algorithmic stablecoin UST pegged to $1 with native token LUNA. High yields from Anchor Protocol drove rapid growth, reaching $18B TVL by early 2022. The design relied on increasing LUNA supply to balance UST demand drops—a fatal flaw when mass withdrawals began.

## The Trigger Point

In May 2022, a $300M UST sell-off on Binance broke the dollar peg. LUNA price collapsed 99.9% in 24 hours. Simultaneously, US inflation data and Fed rate hike expectations accelerated risk asset selloffs. The death spiral mechanism activated as UST fell to $0.30.

## Death Spiral Mechanics

UST's fall triggered hyperinflation—LUNA supply ballooned to 6.5 trillion tokens. Market cap evaporated from $40B to $1B. Major players like Celsius and Three Arrows Capital faced insolvency. 40% of Korean retail investors lost life savings. CEO Do Kwon became an Interpol fugitive.

## Market Contagion

The crash sent shockwaves through crypto: Bitcoin dropped 30%, Ethereum 45%. Total crypto market cap fell from $1.2T to $800B. Even Tether (USDT) depegged to $0.95. Regulators fast-tracked stablecoin oversight, with the EU accelerating MiCA framework adoption.

## Fundamental Design Flaws

Academic analysis revealed UST ignored 'reflexivity' risks—where LUNA's price drop further destabilized UST. Similar algorithmic stablecoins (Frax, MIM) suffered collateral damage. The episode proved that purely algorithmic designs lack crisis resilience without asset backing.

## Institutional Fallout

Despite $2B rescue attempts by Jump Crypto and Delphi Digital, the peg couldn't be restored. Grayscale removed LUNA from its funds. Goldman Sachs compared it to 'Lehman moment' for crypto. Venture capital firms wrote off $28B in Terra-related investments.

## Terra 2.0 Aftermath

The community forked to Terra 2.0, distributing new LUNA tokens—but prices remained below 1% of pre-crash levels. 280,000 Korean investors filed class actions. The SEC classified UST as security, while South Korea issued arrest warrants for Terraform Labs executives.

## Regulatory Reckoning

The collapse became a case study for systemic crypto risks. The FED highlighted 'crypto bank run' dangers. MiCA now requires EU stablecoins to hold liquid reserves. Traditional finance institutions concluded DeFi lacks maturity, slowing institutional adoption timelines.
