Crypto Deleveraging in 2022: Stablecoin Design, Lending Risk, and DeFi Controls

Summary

This letter excerpt reviews the 2022 crypto selloff and a chain of failures involving Terra’s algorithmic stablecoin UST, the LUNA token, Three Arrows Capital, and crypto lenders. It explains UST’s two-way mint-and-burn mechanism and how confidence-driven feedback could reverse into a run. It then describes how leverage, weak collateral practices, yield seeking, and mismatches between liquid customer deposits and longer-duration trades magnified losses across lenders and funds.

The letter contrasts those failures with decentralized lending protocols that used programmed collateral liquidations to manage exposure transparently. It argues that crises can prompt better security and risk controls, while emphasizing that a full causal account requires hindsight. The discussion is a retrospective investor perspective, not an independent quantitative study; the financial figures and claims reflect what the authors understood at the time, and the letter’s optimism about crypto’s future is an opinion rather than evidence of returns.

Key ideas

• UST relied on redemptions between the stablecoin and LUNA, a design vulnerable to loss of confidence and a self-reinforcing run.
• High leverage and overly generous lending, including loans with insufficient collateral, transmitted market losses across crypto firms.
• Some lenders exposed client assets to risky yield strategies or trades whose duration did not match the liquidity of deposits.
• The letter credits on-chain lending liquidations and transparency with helping several DeFi protocols remain solvent during the crisis.
• The account is provisional and retrospective, and its positive outlook for future crypto development is an investment perspective.
