What if the G7 jointly devalues an overvalued dollar?
A Plaza-style coordinated dollar takedown sells DXY, steepens the Treasury long end (foreign reserve managers pull duration) and bids gold/EUR. The 1985 Plaza Accord did exactly this: DXY fell ~50% over two years and the yen/DM ripped. Forward twist: unlike 1985, today's holders are EM central banks already diversifying into gold, so a managed devaluation could overshoot into a disorderly reserve exit rather than the orderly G7-engineered glide of the 1980s.
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

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. Major central banks jointly intervene to weaken an overvalued dollar in a Plaza-style accord, repricing global FX and rates. The trigger decomposes into signed root‑shocks — US dollar (DXY) ▼ · Dollar/reserve confidence ▼ — 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 SPX: the +5/+4% history rests on Nixon Shock and Louvre — 1970s-80s analogues with no comparable rate regime; a Plaza-style devaluation today reprices duration differently.
Historical precedent — what analogous events actually did
Across 13 analogous events (overlap‑weighted), as abnormal returns — market beta stripped, so it's the event's own effect, not the market backdrop. Shown at 20 days (persistent) and 5 days (immediate); ↺ fades = the two horizons disagree. Confidence = consistency × sample × significance.

Why this probability
Plaza-style coordinated devaluation is rare/structural; no real precedent in 40yrs despite generic tags. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
