What if low water paralyses the Rhine, Mississippi and Panama Canal?
Low water on the Rhine/Mississippi/Panama is a logistics-cost and trade-friction shock: barge constraints plus reroutings lift crude/refined products and add a tariff-like tax that hits tech supply chains (Nasdaq, semis). Rhymes with the 2022 Rhine low-water episode and 2023-24 Panama drought draft cuts that spiked container/freight rates. Forward angle: the inflation-expectations and real-yield leg is the durable trade; the equity hit is transient once cargo reroutes.
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 1–3 years 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 mixed shock. Low water on the Rhine/Mississippi/Panama paralyzes critical shipping arteries. The trigger decomposes into signed root‑shocks — Trade tension ▲ · Inflation expectations ▲ · 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 short on MSTR: its +19% realized is pure crypto-bull regime contamination (Iran-strike and tariff-war 2024-25 windows where BTC ripped); a shipping paralysis carries no crypto tailwind.
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
Low-water shipping disruptions on these arteries recurred repeatedly since 2018; near base rate. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
