What this is
A depeg is a sustained departure of a $1-anchored token’s market price from $1. Causes range from collateral losing value, to redemption queues jamming, to a liquidity rush where everyone sells into a thin pool at once. Depth matters: a few basis points is market noise; hundreds of basis points is an event.
What it means for your yield
During a depeg the paper yield is irrelevant — a 10% APY does not cover a 2% haircut on exit. The practical questions become whether official redemption still works at face value, and whether you can afford to wait for it rather than selling into the hole.
Where it appears on Pennyworth
Pennyworth self-judges only $1-anchored products from live price, surfaces only the critical tier (≥200 bps) as a red event bar, and a curated event always overrides the automatic judgment. Share-appreciation tokens price above $1 by design and are never judged this way.
