A major stablecoin collapse represents a failure of confidence in a digital asset designed to function as money. Stablecoins are widely used as units of account, settlement assets, and collateral across crypto markets. When one fails, the effects extend beyond the asset itself and into the broader financial system.
The recent exploit of the USD-pegged stablecoin Resolv (USR) triggered a sharp loss of confidence, with the asset price falling by more than 70 percent and dropping from its intended peg of one dollar to approximately $0.25 within hours. The speed and severity of the decline reflected how quickly markets react when core security assumptions are compromised.
At a fundamental level, stablecoins maintain their peg through three interacting systems: the mechanism that defines how the coin is backed and redeemed, the market structure that enables arbitrage between issuance and trading venues, and the risk management framework that governs liquidity, collateral, and governance decisions.
When these systems operate smoothly, price stability emerges. When they fail, the illusion of stability disappears rapidly. People stop using the stablecoin and start trying to exit it. This creates a run dynamic, where selling increases, liquidity disappears, and the price drops further. Because crypto markets operate continuously, this process can happen very quickly.
Stablecoin risk is no longer confined to crypto-native markets. As adoption expands across payments, treasury management, and financial infrastructure, stablecoins are becoming increasingly intertwined with traditional financial systems. This shift changes the nature of their failure. What was once an isolated market event now carries broader systemic implications.
Institutional adoption has accelerated this transition. Banks, payment providers, and fintechs are integrating stablecoins into settlement flows, cross-border transactions, and liquidity management. For example, firms using USDC for real-time settlement or corporates holding stablecoins for treasury operations are now directly exposed to the stability of these assets. A breakdown in one widely used stablecoin can therefore disrupt not just trading activity, but operational workflows.
This growing reliance introduces concentration risk. A small number of stablecoins dominate market share, meaning that stress in one asset can quickly affect multiple platforms, protocols, and institutions simultaneously.
Back in 2022, the cryptocurrency world experienced the dramatic collapse of the TerraUSD (UST). Within days, billions in value evaporated due to TerraUSD losing its peg to the US dollar. The collapse illustrates how stablecoin design can influence failure outcomes. TerraUSD was an algorithmic stablecoin that relied on a dual-token mechanism involving LUNA to maintain its peg.
This model depended on market confidence rather than underlying reserves. As demand weakened, the stabilisation mechanism became ineffective. Redemptions increased, LUNA supply expanded, and its price declined. Within days, LUNA lost nearly all of its value, falling from over $80 to near zero, while UST dropped well below its peg.
TerraUSD was widely integrated across decentralised finance protocols. It was heavily used in Anchor Protocol, which offered yields of nearly 20 percent, attracting large deposits. It was also present in liquidity pools on Curve and other decentralised exchanges. When UST depegged, these pools became heavily imbalanced, with users rushing to exit UST positions. The result was a cascading failure. Lending platforms faced bad debt, liquidity providers incurred losses, and forced liquidations amplified market volatility. The event demonstrated how stablecoin failures can propagate through interconnected systems and highlighted the risks of relying on reflexive design.
Not all stablecoins fail the same way, but they all fail when redemption stops being credible. The failure mechanism differs by stablecoin type:
Fiat-backed stablecoins are exposed to risks related to reserve adequacy, liquidity, and operational access. For example, during periods of market stress, questions around Tether’s commercial paper holdings previously led to temporary deviations from its peg. Even short-lived uncertainty can trigger significant market reactions.
Crypto-collateralised stablecoins rely on volatile assets as backing and maintain stability through overcollateralisation and liquidation mechanisms. MakerDAO’s DAI, for instance, requires users to lock up more value in collateral than the stablecoins they mint. However, during extreme market downturns, such as the March 2020 crash, rapid price declines and network congestion led to liquidation failures and temporary system imbalances.
Algorithmic stablecoins, by contrast, fail most dramatically, as they rely on market confidence and reflexive incentives rather than enforceable redemption rights, making them prone to rapid and irreversible “death spirals.” TerraUSD is the most prominent example, but similar designs have struggled to maintain stability under stress. These systems are sensitive to shifts in demand and can experience rapid, self-reinforcing collapse when market sentiment changes.
Across all models, collapse events tend to propagate through a consistent set of contagion channels, including panic selling, redemption surges, collateral liquidations, DeFi cascading failures, liquidity pool imbalances, and ultimately spillovers into traditional financial markets.
In fast-moving collapses, there’s often no time to exit before severe losses.
For users, losses depend on timing and access to liquidity. During the TerraUSD collapse, many holders were unable to exit before the price fell significantly below one dollar. Similarly, during the USDC depeg, users who sold at a discount realised losses despite the eventual recovery.
In decentralised finance, stablecoins function as collateral and base assets. When a stablecoin loses its peg, lending markets can become undercollateralised. For example, protocols like Compound have historically relied on stablecoins as core collateral assets. A sharp deviation can lead to liquidation cascades and bad debt.
Liquidity pools on decentralised exchanges are also affected. On platforms like Curve, stablecoin pools rely on balanced liquidity between assets such as USDT, USDC, and DAI. When one asset depegs, pools become skewed, concentrating risk in the weaker asset and increasing slippage for traders.
At the market level, stablecoin failures reduce liquidity and increase volatility. Spreads widen, trading activity slows, and capital moves toward perceived safer assets. In larger events, such as TerraUSD, the impact extends beyond crypto markets, contributing to broader risk-off sentiment.
Stablecoin stability depends on credible redemption, high-quality reserves, and effective market infrastructure. When these conditions are met, stablecoins can maintain their peg even under moderate stress. When they are not, stability can break down quickly.
Recent events, including TerraUSD in 2022 and USDC in 2023, demonstrate that even widely adopted stablecoins can experience periods of instability. These episodes highlight the importance of transparency, liquidity, and operational resilience.
As stablecoins become more integrated into financial systems, their robustness becomes increasingly important. Systems that prioritise clear redemption processes, strong reserve management, and resilient infrastructure are more likely to maintain stability under pressure. Understanding how stablecoins function, and how they fail, is essential as they continue to evolve into core components of global financial infrastructure.
Stablecoin failures highlight a broader issue: digital assets introduce new forms of risk that traditional financial infrastructure was not designed to handle. These risks include loss of access, transaction errors, fraud, and operational failures, all of which can compound during periods of market stress.
