What if a mega-ship blocks the Suez Canal again?
A three-week Suez wedge strands ~12-15% of global trade, spiking Asia-Europe box rates and a real Brent premium as tankers detour Cape of Good Hope, with VIX bid on the tail. Rhymes precisely with the March-2021 Ever Given grounding (six days, ~$9bn/day held up) and the 2024 Houthi reroutes that doubled Shanghai-Rotterdam rates. Europe is the most exposed importer; the forward angle is carriers now have Cape-routing muscle memory from 2024, so the freight spike normalizes faster than a first-time shock.
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 Tail risk 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 grounded mega-boxship wedges Suez for three weeks, stranding 15% of global trade and spiking Asia-Europe rates. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · Inflation surprise ▲ · Oil supply risk ▲ — 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 long on CL/BRENT: only 5 analogues and the negatives are 2014/2020 oil-glut crashes — a Suez closure is a genuine supply chokepoint, so the stale price-war sample misreads the sign.
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
Single mega-ship wedging Suez 3 weeks is rare one-off; tail-risk framing, low base rate. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
