What if copper smelting fees turn negative?
The 2027 copper-concentrate benchmark settling negative forces major Chinese smelter closures, paradoxically tightening refined copper even amid weak China growth — the move is refined copper and Freeport higher on lost smelting, with the China-growth-down legs capping it. Rhymes with the early-2024 TC/RC collapse toward zero after the Cobre Panama loss, which forced CSPT smelter-cut talks and lifted copper. Forward angle: negative TCs mean smelters pay for concentrate — unsustainable, so capacity rationalizes structurally, removing refined supply into rising grid/AI demand; the trade is the refined-vs-concentrate squeeze, long copper against smelter margins.
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 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. The 2027 copper concentrate benchmark settles outright negative, forcing major Chinese smelter closures and tightening refined copper. :: The trigger decomposes into signed root‑shocks — Copper ▲ · China growth ▼ — 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.

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
TCs collapsing toward zero on smelter overcapacity; an outright-negative 2027 benchmark is a credible extreme. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
