What if a mine campaign hits tankers at a major loading zone?
Limpet-mine attacks in a major loading zone choke exports and price a hard supply tail — Brent gaps higher and the VIX/Nasdaq/risk-parity deleveraging leg dominates given the explicit tail-risk framing. Direct analogue: the 1980s Tanker War and the May-June 2019 Gulf-of-Oman limpet-mine attacks, which spiked war-risk premia and crude. Forward angle: spare OPEC capacity is thin and SPRs are depleted post-2022, so the buffer that capped the 2019 move is smaller now — fatter right tail on oil.
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 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. Limpet-mine attacks on tankers in a major loading zone choke exports and spike risk premia. 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: COIN/MSTR/HOOD's +18-22% history clusters entirely in 2024-25 Israel-Iran/tariff windows where BTC was structurally bid — a swamped channel, the mine-attack risk premium won't lift crypto proxies the way the regime did.
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
Limpet-mine tanker campaign is a specific tail event; rarely materializes. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
