Can Investors Insure Stablecoins Against a Depeg?

On-chain depeg insurance exists and has paid claims. In 2022 InsurAce paid $11.7 million to 155 policyholders after TerraUSD collapsed; Nexus Mutual excluded UST under its policy definitions.

Depeg policies set a price threshold and a time window that must both be met for a payout. Typical terms require a covered stablecoin to trade below about $0.98 to $0.99 and remain under that level for a sustained period, commonly 24 consecutive hours, measured against specified price feeds.

Two operating models determine how claims are handled. Parametric cover relies on objective price data and executes payments automatically when predefined conditions are satisfied. Discretionary cover routes claims to a governance vote where members review evidence and approve or reject payouts. InsurAce’s parametric UST coverage triggered on price data and paid claims; Nexus Mutual’s discretionary approach treated the TerraUSD event as an economic risk outside its coverage terms.

Policy exclusions affect outcomes. Many depeg products exclude losses caused by regulatory action. User errors such as sending funds to the wrong address and scams are not covered. Other common exclusions include market risks like impermanent loss and liquidation events, and loss of private keys.

Underwriting capacity limits available coverage. Nexus Mutual holds roughly $198 million in total value locked and InsurAce about $150 million. Those pools are significant for individual claims but small compared with the stablecoin market, which exceeds $300 billion. Demand for cover typically rises after depeg events; InsurAce reported premium growth of about 35% year over year partly driven by demand following depegs.

Depeg claims account for a substantial share of DeFi insurance activity; they represented roughly 22% of claims overall. Nexus Mutual reports having protected more than $6 billion in digital assets since 2019 and paying out over $18 million in claims across exploits, technical failures and halted withdrawals.

Contract details determine whether a claim will pay: the model (parametric or discretionary), the exact trigger price and required duration, which specific issuers or token variants are named, and any exclusions, particularly for regulatory action.
