What if a forged ECB rate decision goes viral before markets open?
A forged ECB rate release is a bund/euro whipsaw that reverses on official denial: front-end EUR rates and the euro gap on the fake decision, then snap back within minutes. No clean analogue; nearest rhymes are fat-finger/fake-headline flash events (the 2013 hacked-AP 'White House explosion' tweet, S&P -1% then full recovery). The skeptical read: this is a liquidity-air-pocket, not a regime change — the move is a fade, and the residual risk is algos that trade headlines.
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 Imminent 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. Forged ECB rate-decision release goes viral pre-market, bunds and euro whipsaw before official denial. The trigger decomposes into signed root‑shocks — Fed policy path ▲ · Risk appetite ▼ — 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 short on SOL: the +20% leans on the 2021 lira-plunge and 2022 Fed-liftoff windows when SOL was in its own bull, swamped by crypto beta, not an ECB-forgery whipsaw.
Historical precedent — what analogous events actually did
Across 40 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
Forged central-bank releases plausible but market-moving viral fake rare; imminent window tight. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
