What if Europe's last zinc smelters go dark?
Power costs forcing Nyrstar to idle its last European zinc smelters deepens a structural refined-metal deficit — the move is European zinc premiums and refined zinc higher on lost smelting, tied to the energy-cost channel; copper is incidental. Rhymes with the 2021-22 European energy crisis that idled ~half of EU zinc/aluminium smelting and spiked physical premiums. Forward angle: this is an energy-driven supply destruction, so it is hostage to TTF gas — if power stays high, smelter capacity leaves Europe permanently, structurally widening the import-reliant deficit; play physical premiums and energy-exposed smelters.
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. Power costs force Nyrstar to idle remaining European zinc smelters, deepening a structural refined-metal deficit. The trigger decomposes into signed root‑shocks — European energy ▲ · Industrial demand ▲ — 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 XPT/XPD: history's -15% reflects the 2008 commodity-bull deleveraging crash, not a supply shock — every analogue is a 2008 oil/gas blowoff, a contaminated regime.
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 zinc smelters chronically power-squeezed; Nyrstar idling remaining capacity is a continuing trend. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
