What if central banks set formal dollar-cap and gold targets?
A multi-CB bloc capping dollars and setting gold-accumulation targets puts a structural bid under bullion and a structural offer on the UST long end; DXY and EUR reprice, BTC catches the non-sovereign-reserve flow. This extends the post-2022 reserve-manager gold buying (record official purchases after Russia's reserves were frozen) into explicit policy. The cleaner trade is long gold on the official-demand floor; the BTC leg is higher-beta narrative, not reserve fact.
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. A bloc of central banks jointly announces formal multi-year caps on dollar reserves and gold-accumulation targets, driving a step-change structural bid under bullion. The trigger decomposes into signed root‑shocks — Gold ▲ · 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% rests on Nixon/Louvre 1970s-80s prints — a different rate regime; a coordinated reserve-cap term-premium shock today reprices equities down, history is stale.
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
Coordinated multi-year dollar-cap bloc is unprecedented; central banks diversify quietly, not by treaty. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
