What if Mexico loses its USMCA tariff exemption?
A 30% wall on Mexican goods is a peso and US-auto shock, not primarily a China/Nasdaq event: USDMXN gaps higher and Ford/GM/Stellantis margins compress on broken cross-border supply lines while Mexico's grain retaliation lifts CBOT corn. Rhymes with the 2018 NAFTA-renegotiation scare and Trump's 2019 5%-tariff tweet that spiked USDMXN ~3% intraday. Mexico is the US's largest goods partner and runs deep auto integration, so transmission is bilateral and fast; the novel risk is nearshoring capex already sunk, amplifying the hit.
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 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 risk-off shock. US ends USMCA produce and auto carve-outs, imposing 30% on Mexican-origin goods; peso slides and Mexico retaliates on US grain. The trigger decomposes into signed root‑shocks — Growth surprise ▼ · Inflation surprise ▲ · Trade tension ▲ · EM currencies ▼ — 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 short on MSTR: the +10% realized is BTC's 2025 bull regime bleeding through Liberation-Day windows, not a peso/USMCA channel — crypto swamps this macro shock entirely.
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
Tariff shocks recur, but full USMCA carve-out repeal in 6mo is legally/politically heavy. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
