What if the dollar falls below half of global FX reserves?
Dollar reserve share dropping below 50% is a confidence milestone, so the trade mirrors de-dollarization: long end selling (30y +11bp), gold (+3%) and bitcoin bid, DXY lower — a slow-burn term-premium repricing, not a crash. Rhymes with the multi-decade post-Bretton-Woods erosion and the post-2022 acceleration in central-bank gold buying. Forward angle: the milestone is largely a lagging confirmation of flows already underway, so the marginal market impact is smaller than the headline — gold is the asset that front-runs it.
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 3–10 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. The US dollar falls below 50% of global FX reserves — a reserve-dominance milestone. The trigger decomposes into signed root‑shocks — 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 SPX short: the +1.5% history leans on a stale 1971-1987 cluster (Nixon, Volcker, Louvre) plus Russia-freeze contagion — none comparable to a sub-50% reserve-dominance break today.
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
USD reserve share ~58% drifting down slowly; sub-50% within a decade possible but not base case. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
