Stablecoin depeg >2% on shared-LP venue

Usual (USD0 / bUSD0 / USUAL)'s assessment for RD-F-104 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

bUSD0 (formerly USD0++) trades at $0.9636 (CoinGecko 2026-05-17) — a 3.64% discount to par, above the 2% T-09 threshold, sustained for months since the January 2025 depeg event. USD0 itself trades at $0.9981 (well within the 2% threshold). The suppression question: the bUSD0 floor mechanism (introduced 2025-01-09, DAO-acknowledged per Usual blog 2025-01-23) provides a suppression argument — the discount reflects a structural design feature (locked bond maturing June 11, 2028), not a sudden depeg. Under strict T-09 dependency-map reading, bUSD0 depeg does not directly impair USD0 collateral backing (USD0 is backed by USYC/USTBL, not by bUSD0). Yellow reflects: threshold breach is real, but suppression argument is present; the signal should be flagged 'elevated but suppressed' pending T-09 methodology clarification on whether a DAO-acknowledged floor price constitutes adequate suppression.
