What if a stale Chainlink price feed drains DeFi lending markets?
A stale Chainlink ETH feed letting an attacker borrow against mispriced collateral drains lending markets cross-chain — an oracle-integrity shock that hits ETH (-5%) and DeFi-levered names via bad-debt fear. Echoes prior oracle-manipulation exploits (Mango, bZx) where a price-feed failure, not market direction, caused the loss. Because Chainlink underpins most DeFi pricing, the real exposure is the shared-dependency monoculture: one feed failing socializes bad debt across every protocol that trusts it.

What it would mean
If this plays out, it is a mixed shock. A frozen Chainlink ETH feed lets an attacker borrow against mispriced collateral, draining lending markets across multiple chains. The trigger decomposes into signed root‑shocks — Crypto confidence ▼ · Crypto liquidity ▼ — which propagate through our causal graph to the markets below.
