Oracle Price Update Delay

Oracle price update delay occurs when the price feed providing data to a decentralized finance protocol lags behind the actual market price on major exchanges. Because smart contracts rely on these external data points to trigger liquidations, a delay means the protocol is making decisions based on stale information.

If the market crashes suddenly, the oracle might report a price higher than reality, preventing the liquidation engine from firing. This gap allows a borrower to maintain an undercollateralized position longer than intended.

As the real market price falls further, the eventual liquidation may fail to cover the loan entirely. Protocol designers mitigate this using multi-source oracles and frequent heartbeat updates to reduce the time delta.
