Credit risk is the possibility that a borrower or counterparty fails to repay a loan or fulfill contractual obligations, creating potential losses for the lender. In traditional finance, this is often called default risk, and in crypto it applies anywhere value is extended on the assumption it will be returned.
How credit risk appears in crypto markets
In cryptocurrency, credit risk shows up in both centralized and decentralized lending. On a centralized platform, users may lend assets to an exchange or lending desk and rely on that institution to manage borrowers, liquidations, and custody. If borrowers default or the platform mismanages risk, lenders can face losses.
In DeFi, lending protocols reduce direct borrower default risk by requiring collateral and using smart contracts to enforce rules. For example, if someone borrows a stablecoin against ETH collateral and the collateral value falls below a threshold, the position can be liquidated to repay the debt. This design shifts the risk from “will the borrower pay” to whether the liquidation process works under stress, and whether collateral and oracle pricing remain reliable.
How credit risk is measured and managed
Institutions typically quantify credit risk before extending credit, using credit scores or ratings, financial statements, collateral quality, and exposure limits. In crypto, similar ideas apply, but the data sources differ. On-chain activity, collateral composition, loan-to-value ratios, and counterparty concentration can matter as much as traditional identity-based underwriting.
Credit ratings and internal risk models aim to estimate the probability of default and the expected loss if default occurs. Even with collateral, lenders still consider factors like asset volatility, liquidity during sell-offs, and operational risk at the venue.
