On May 4, 2022, the Terra ecosystem sat at the pinnacle of its power. LUNA traded at $86 with a market capitalization approaching $30 billion, its algorithmic stablecoin UST held steady at $1.00, and the Anchor Protocol had attracted nearly $14 billion in deposits from yield-chasing investors. It was, by every measurable metric, the high-water mark of one of crypto’s most ambitious experiments — and the beginning of its end.
TL;DR
- LUNA traded at $86.17 with a market cap of approximately $29.6 billion on May 4, 2022
- Anchor Protocol held nearly $14 billion in UST deposits, offering 19.5% APY
- The Luna Foundation Guard (LFG) managed over 80,000 BTC ($3 billion) in reserve
- Total DeFi TVL across all chains stood at $200.5 billion — a historic peak
- Within 5 days, UST would lose its peg and trigger a $40 billion collapse
The Anchor Protocol Money Machine
At the heart of Terra’s explosive growth was Anchor Protocol, a decentralized lending platform on the Terra blockchain that offered a fixed 19.5% annual percentage yield on UST deposits. By May 4, Anchor had accumulated approximately $14 billion in UST deposits — representing roughly 77% of the total UST supply of $18 billion. The platform had become, in effect, a black hole for capital, drawing in deposits from across the crypto ecosystem with yields that no traditional financial institution could match.
The problem, which would soon become catastrophically apparent, was that Anchor’s yield was unsustainable. The protocol generated far less in actual borrowing demand than it paid out in interest, making up the difference through reserves that were being depleted at an accelerating rate. By early May, Anchor’s yield reserve had fallen to critical levels, requiring repeated injections from the Terra community treasury to maintain the headline-grabbing 19.5% rate.
LFG’s $3 Billion Bitcoin Reserve
The Luna Foundation Guard had been aggressively accumulating Bitcoin throughout early 2022, building a war chest of over 80,000 BTC worth approximately $3 billion at prevailing prices. The stated purpose was to defend the UST peg in times of market stress — if UST ever dropped below $1, the LFG would deploy its Bitcoin reserves to buy UST and restore the peg.
The strategy reflected the growing sophistication of the Terra ecosystem’s risk management, but it also revealed a fundamental tension. An algorithmic stablecoin that required $3 billion in external reserves to maintain its peg was, in many ways, an admission that the algorithmic mechanism alone was insufficient. The Bitcoin reserve was both a safety net and a signal of vulnerability.
DeFi TVL at $200 Billion — The Last Milestone
May 4, 2022 marked one of the final data points before DeFi’s total value locked reached its all-time high. Across all blockchain networks, approximately $200.5 billion was locked in DeFi protocols. Ethereum held the dominant position with roughly $110 billion in TVL, representing 55% of the market. Terra ranked second at $29.8 billion (14.8%), followed by BNB Chain at $13 billion.
The distribution was telling. Terra’s $29.8 billion in DeFi TVL was almost entirely concentrated in Anchor Protocol and a handful of related applications, creating an ecosystem that was deeply interconnected and dangerously dependent on a single yield product. When Anchor’s reserves would eventually run dry, there would be nothing to stop the cascade of liquidations and redemptions that followed.
Altcoin Ecosystem Thrived Alongside Terra
Beyond Terra, the broader altcoin market was experiencing its own moment of optimism on May 4. Solana (SOL) traded at $92.77 despite ongoing network reliability issues that had plagued the blockchain since late 2021. Avalanche (AVAX) stood at $67.09, buoyed by corporate partnerships and its subnet architecture. Cardano (ADA) surged 16% to $0.90 as its community anticipated the Vasil hard fork.
TRON (TRX) posted a remarkable 19% daily gain to $0.086, driven by its growing stablecoin settlement volume and the Justin Sun-led network’s aggressive expansion into decentralized finance. Even smaller altcoins participated in the relief rally, with the CoinMarketCap top 100 posting an average gain of 7% on the day.
The Warning Signs Hidden in Plain Sight
For all the optimism, several red flags were visible to attentive observers. The concentration of UST supply in Anchor meant that a bank run on the protocol could overwhelm the LFG’s Bitcoin reserves. On-chain analytics showed that a handful of large wallets controlled a disproportionate share of UST, making the ecosystem vulnerable to coordinated selling. The death spiral mechanism — where UST depegging would trigger LUNA minting, which would drive down LUNA’s price, which would further deplete the reserves available to defend the peg — was well-documented in academic papers on algorithmic stablecoins.
The broader macro environment was also deteriorating. The Federal Reserve’s 50 basis point rate hike on this same day signaled the beginning of the end for the “cheap money” era that had fueled crypto’s explosive growth since 2020. As risk-free rates in traditional finance rose, the appeal of a 19.5% yield on a risky algorithmic stablecoin would diminish for rational investors.
Why This Matters
May 4, 2022 is etched in crypto history as the day Terra was at its absolute zenith — and the beginning of its unraveling. The $14 billion locked in Anchor, the $3 billion Bitcoin reserve, and the $200 billion total DeFi TVL were all about to evaporate in one of the most spectacular collapses in financial history. Within 72 hours, UST would begin losing its peg. Within a week, LUNA would go from $86 to fractions of a cent. The contagion would wipe out hundreds of billions in crypto market cap and trigger a wave of bankruptcies including Celsius, Three Arrows Capital, and Voyager Digital. This date serves as a stark reminder that in crypto, the view from the top can be the most dangerous place to be.

LFG holding 80k BTC as reserve was supposed to be the backstop. instead it became the biggest forced seller in crypto history
I was one of the idiots who thought 19.5% was sustainable. the chart looked like a straight line up and I ignored every red flag. expensive lesson
Anchor offering 19.5% APY on UST deposits should have been the biggest red flag in crypto history. $14B parked there believing yield comes from nowhere
Tomasz W. anchor was paying 19.5% from a reserve fund that was depleting. people did the math in feb 2022 and got called fudders. wild
LFG holding 80,000 BTC as a reserve fund and it still wasnt enough. the peg mechanism was mathematically doomed once sell pressure exceeded their backup

anchor_widow the 80k BTC reserve at LFG lasted maybe 48 hours once the bank run started. thought it was a war chest, turned out to be a speed bump
Noah Patel LFG lasting 48 hours with 80K BTC tells you the bank run was already underway before they started defending. on-chain data showed UST outflows accelerating 72 hours before the BTC deploy
the yield was coming from new deposits plain and simple. classic ponzi dynamics dressed up in defi terminology. anyone asking questions got shouted down
vault_pike_ the Anchor Reserve was literally paying the yield from its own treasury. when the reserve ran dry the math stopped working. pure circular logic
the total defi tvl at $200.5b was the all-time high and terra was a huge chunk of it. when ust depegged it dragged everything down
Terra was roughly 15% of total DeFi TVL at peak. when it collapsed it was not just LUNA holders who got rekt, every protocol with UST exposure cascaded
block_pike_ is spot on about the cascade. every protocol with UST exposure got dragged down. it wasnt just a LUNA thing
5 days. went from $30b market cap to dust in 5 days. the lfg had 80k btc and it wasnt enough to defend the peg
reading about the $3b BTC reserve and knowing it wasnt enough to save the peg. algorithmic stablecoins are fundamentally broken
14 billion in Anchor at 19.5% APY means they were paying 2.7 billion a year in yield from a reserve that was depleting. the math was public on-chain for months before the collapse
80K BTC at LFG sounded like a war chest until the bank run started. lasted 48 hours. algorithmic pegs dont survive coordinated selling, no reserve is big enough
