What if a Chinese and Taiwanese warship collide mid-strait?
A median-line warship collision with fatalities is an escalation-spiral catalyst, not yet a fab event: VIX +12, Nasdaq -5, crypto-beta leads down on the unknown. Rhymes with the 2001 Hainan EP-3 incident, which roiled US-China sentiment but resolved diplomatically. The key tell is whether either side frames it as accident or attack. Forward angle: with both navies now far larger and operating closer, the collision baseline is higher than 2001, so fade-the-dip only after de-escalation signals.
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 0–6 months 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 PLA and Taiwanese warship collide near the median line, killing sailors and igniting an escalation spiral. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · 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 COIN/MSTR: only 7 analogues, all geopolitical-bounce windows during BTC's 2024-25 structural bull — thin, regime-contaminated sample; a strait collision breaks the risk-proxy rally pattern.
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
Median-line collisions plausible amid dense PLA ops, but fatal warship clash uncommon in 6mo. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
