ETH: Liquity: System Collateral Ratio

Shown as its 2019–2022 sample; the latest readings and full history are included with Plus.

Liquity v1's total ETH collateral value divided by its total LUSD debt.

Why use it. Liquity is an over-collateralised system with no governance: this ratio is its single health number; below 150% the system goes into recovery mode. How to read it. Higher is safer; a fall towards 150% is a warning.

Calculation. TroveManager.getEntireSystemColl() times PriceFeed.lastGoodPrice() over getEntireSystemDebt(). Computed by CryptoKeyhole from its own Ethereum archive node: each protocol's own contracts read at the last block of every UTC day (the latest finalized block for the day still open). Only these systems are read: other collateralized stablecoins are not counted, and every figure is the contract's own report.
