What if a fertiliser shortage threatened the next planting season?
A potash/ammonia shortage raises grain input costs ahead of planting, feeding grain prices and food CPI with a lag rather than immediately — fertilizer is a cost-push that shows up in next season's acreage and yields. Rhymes with the 2022 post-invasion fertilizer spike (Russia/Belarus potash, gas-driven ammonia) that pressured global planting economics. Transmission: Belarus/Russia dominate potash and Russia gas drives ammonia, so the shock is geopolitically gated — the durable read is EM food-import FX fragility, with the grain move arriving a season later.
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 6–18 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 potash/ammonia fertilizer shortage threatens the next planting season. The trigger decomposes into signed root‑shocks — 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 WHEAT: the -3.7% is swamped by an unrelated BHP/Anglo M&A collapse and copper windows; no analogue here is an actual fertilizer/potash shock, so the base rate is off-channel noise.
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
Gas-linked fertilizer squeeze possible but no acute trigger evident mid-2026. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
