What if Moody's strips the US of another notch to Aa2?
A second Moody's notch on the US is symbolic, not forced-selling — Treasuries remain the reserve asset, so the durable move is a steeper curve and firmer term premium, not a dollar collapse. Rhymes with S&P's August 2011 downgrade, which paradoxically rallied Treasuries in a risk-off bid. Note the cascade has gold and BTC falling alongside a stronger DXY, which is internally consistent for a confidence-up read but unusual for a downgrade; the forward angle is that repeat downgrades dull the signal — each one moves less.
how we built this number — every step
The class rate is measured from our dated, sourced event library (decade-normalized Poisson — the full table is public at base_rates.json). The variant’s share within its class is the analyst’s editorial call, published so you can audit it. A wider range means thinner precedent. Full recipe: methodology · scored at Reality Check.
The butterfly cascade
How this trigger trickles across markets, left → right — the root shock, its first‑order moves, then the ripple effects. Drag any node; tap a market for its real price history.
Resolution timeline — how this probability is moving
Our model's odds (gold) over time vs the crowd's (Polymarket, blue), from the past toward the 1–3 years horizon. Each dot is a real macro event that nudged the probability — green pushed it up, red pushed it down. Tap a dot for the source. The gold path is an illustrative reconstruction anchored to today's estimate — real dated events, not a live re-estimate history.
What it would mean
If this plays out, it is a risk-off shock. Moody's strips another notch to Aa2 as federal debt approaches 134% of GDP, repricing risk-free benchmarks again. The trigger decomposes into signed root‑shocks — Credit spreads ▲ · Dollar/reserve confidence ▲ · Real yields ▲ — which propagate through our causal graph to the markets below.
If it happens — the markets it would move
Biggest moves first. Projected moves are cascade-model priors; hist A–B% = what comparable past events actually did (measured abnormal returns), and model prior · unmeasured marks markets with no analogue backing yet. Tap any market for its price history.

Probable recommendation
Why we may diverge from history
Trust the cascade's SHORT on GBPUSD: the +1.8% history is regime-contaminated — all three drivers are the March-2023 SVB dollar-funding scramble, not a slow US sovereign downgrade repricing risk-free benchmarks.

Why this probability
US fiscal trajectory worsening, debt near 130%; further Moody's notch plausible over 1-3yr. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
