Why Stablecoins Lose Their Peg and What It Means for Your Investments

The cryptocurrency market was shaken in May 2022 when TerraUSD (UST), a stablecoin pegged to the US dollar, collapsed to just 10 cents. This event erased over $60 billion in market value overnight, highlighting a critical truth: not all stablecoins are truly stable.

Despite their name, stablecoins—digital assets designed to maintain a 1:1 peg with fiat currencies like the USD—are vulnerable to volatility. In 2023 alone, CoinGecko recorded more than 50 depegging incidents, some lasting hours, others sparking widespread panic.

But why do stablecoins lose their peg? The reasons range from liquidity shortages and flawed algorithms to market manipulation and eroded trust—often hidden until it’s too late.


Key Takeaways

  • Stablecoins aim to mirror the value of assets like the USD but can deviate due to systemic risks.
  • Depegging triggers market instability, affecting investor confidence and liquidity.
  • Transparency, audits, and robust collateralization are vital for maintaining peg stability.
  • Regulatory scrutiny intensifies after depegging events, focusing on compliance and investor protection.

What Does It Mean for a Stablecoin to Depeg?

Depegging occurs when a stablecoin’s value drifts from its pegged asset (e.g., 1 USD). This deviation can lead to:
Price fluctuations: Values may drop below or spike above the peg.
Market contagion: Loss of trust can spread to other cryptocurrencies.

Types of Stablecoins and Their Risks

1. Fiat-Backed Stablecoins

Examples: USDT (Tether), USDC (Circle)
Mechanism: Backed 1:1 by fiat reserves.

Risks:
Reserve mismanagement: Insufficient collateral or risky investments.
Regulatory crackdowns: Bans or strict laws destabilize the peg.

2. Crypto-Backed Stablecoins

Examples: DAI (MakerDAO), MIM (Abracadabra)
Mechanism: Over-collateralized with cryptocurrencies.

Risks:
Collateral volatility: ETH or BTC crashes reduce backing value.
Smart contract bugs: Exploits can collapse the system.

3. Algorithmic Stablecoins

Examples: Former TerraUSD (UST)
Mechanism: Algorithms adjust supply to match demand.

Risks:
No collateral: Bank runs or lost confidence cause death spirals.
