What if a gas-price spike shuts down ammonia plants?
A European gas spike forcing ammonia/urea plant closures cuts global nitrogen supply — the trade is long urea/UAN and a weaker EUR on the energy-import hit, with grain-input cost pass-through; this cascade is the most accurate in the batch. Rhymes with the 2021-22 TTF surge that idled ~half of EU ammonia capacity and spiked nitrogen fertilizer. Transmission: EU growers and import-dependent farmers globally absorb the cost; CF Industries (cheap US gas) gains. Forward: Europe's structural gas-cost disadvantage makes its nitrogen capacity the perennial swing-off, so spikes recur each cold snap.
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 mixed shock. A European gas-price spike forces widespread ammonia and urea plant closures, cutting global nitrogen fertilizer supply. The trigger decomposes into signed root‑shocks — European energy ▲ · Fertilizer cost ▲ — 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 CORN: history's -2% rides 2025 Iran/Hormuz oil-scare windows that crushed risk broadly — a gas-driven ammonia shutdown starving nitrogen feedstock is a direct fertilizer-to-corn long.
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
European gas spike forcing ammonia shutdowns happened in 2021-22; 2026 gas calmer, needs fresh supply shock. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
