What if a nuclear accident sparks a global reactor-shutdown wave?
A nuclear-accident-driven reactor-shutdown wave shifts baseload onto gas/coal, lifting European gas, fertilizer and grain costs and nudging EUR/USD lower. The textbook analogue is post-Fukushima (2011), when Germany's nuclear exit and Japan's fleet shutdown durably raised LNG/gas demand. The provided oil-event analogues are mismatched. Forward angle: the trade is structural European gas and power, not oil — and the EUR drag is second-order versus the direct TTF/power-curve repricing.
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 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. A nuclear accident triggers a global reactor-shutdown wave, lifting gas/coal demand. The trigger decomposes into signed root‑shocks — European energy ▲ · Natural gas ▲ — 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 NG: history is dominated by record-output gluts and the priced-in 2025 Ukraine-transit unwind — wrong-sign analogues for a nuclear-driven gas-demand surge; off-channel sample.
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
Global reactor-shutdown wave needs a major accident; rare structural tail. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
