A what‑if from the future

What if a lock failure shuts down the Kiel Canal?

A Kiel lock failure reroutes Baltic feeder traffic around Denmark - a regional shipping inconvenience, not a macro event - so the tiny sub-0.2% rates/EUR moves are correctly scaled and this barely registers beyond intra-European logistics. No real market analogue; it is too small to rhyme with energy-crisis episodes. Germany/Scandinavia/Baltics are the affected feeder lanes; the forward angle is the european_energy root slightly overstates it - Kiel is mostly dry-bulk and feeder, so even EUR/USD -0.1% may be generous.

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 mixed shock. A catastrophic lock failure shuts the Kiel Canal, rerouting Baltic feeder traffic the long way around Denmark. The trigger decomposes into signed root‑shocks — European energy ▲ · Inflation surprise ▲ — 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.

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

Catastrophic Kiel lock failure is rare structural one-off; tail risk, minimal base rate. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.

Methodology. Probability and impact are anchored to history and scored against what actually happens — wins and losses, in public, at Reality Check. Crowd odds live from Polymarket & Kalshi. By Vikas Singh, Quantitative Strategist. Updated 2026-07-03.
