What if Somali piracy resurges and reroutes global shipping?
A Somali piracy wave is a freight-and-insurance shock, not a crude shock: the actionable move is tanker/container rates and war-risk premia, so the modest +1.8% Brent overstates the supply leg. Rhymes with the 2008-2011 piracy peak and the 2024 Houthi Red Sea reroute, which spiked Suez-to-Cape shipping costs far more than oil. Transmission: Asia-Europe trade rerouting around the Cape lengthens voyages and tightens vessel supply. Forward: navies are pre-positioned post-Houthi, so containment is faster than 2008.
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.

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 wave of hijackings off Somalia and Puntland forces shippers to reroute, lifting insurance and freight costs sharply. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · 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 CL/BRENT; the realized -7% oil sample is built from demand-shock price wars, not a piracy-driven freight/insurance supply squeeze, where the 2022 supply analogue runs +25%.
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.
