A what‑if from the future

What if an exchange cancels a day of trades after a squeeze?

An exchange cancelling a day of trades after a squeeze destroys trust and pushes volume off-exchange — the trade is a liquidity/credibility hit to that venue and wider bid-ask in the affected metal, with the miner (Freeport) a modest tracker. Direct rhyme: the LME's March-2022 nickel cancellation, which drove volumes away, invited lawsuits, and impaired the exchange's franchise for years. Skeptical: the macro spillover is small and venue-specific; the cascade's broad credit/crypto legs overstate it. Roots are acceptable for a contained metals-microstructure event.

What it would mean

If this plays out, it is a mixed shock. An exchange cancels a day of nickel-style trades after a squeeze, destroying trust and driving volume off-exchange. The trigger decomposes into signed root‑shocks — Copper ▲ · Financial conditions ▲ — which propagate through our causal graph to the markets below.
