# Yield Bait, Grade Rot

## Executive Summary

USDC bleeds $1.39B as USDS, USDe, and USDf yield-spike simultaneously. GHO downgrades to B. PGOLD loses 95% of DEX liquidity overnight. PSI reads 89.2; the rot is beneath it.

## Extended

PSI climbed to 89.2 from 87.1 six days ago, its best reading of the week, yet the TENSION regime persists because the stress is migrating, not vanishing. The 7-day trajectory shows market cap drifting sideways near $325.3B while USDC quietly shed $1.39B in a week, falling 3% below its $79.58B ATH from March 17. That capital is going somewhere, and the yield signals suggest where.

**Yield Signal** USDC is printing 39.26% APY against a 30-day average of 25.69%, a divergence wide enough to attract fast money. USDS and USDe are both spiking above 3.5% APY from 30-day averages under 1%, and USDf nearly quadrupled its monthly baseline to 5.68%. Three mid-cap coins simultaneously flashing yield spikes while USDC bleeds supply is not coincidence; it is capital chasing incentives at the expense of grade quality.

**Grade Rot** GHO dropped from B+ to B at $583M, the largest coin by market cap to downgrade this cycle, with liquidity scoring just 54. IUSD slipped to C at $118M. The upgrades are thinner: USD1 climbed to B+ at $4.39B on near-perfect peg, but its rise looks lonely next to GYD still sitting at WARNING with a DEWS score of 61 and liquidity erosion reading 79. PGOLD's DEX TVL collapsed 95% overnight, from $713K to $38K, on an $88M coin. When the plumbing drains that fast, the peg score is just a number waiting to update.
