A what‑if from the future

What if the US launches direct strikes on cartels in Mexico?

US strikes inside Mexico plus a border shutdown is a USMCA/peso rupture, so the actionable trade is MXN and auto-supply-chain names -- the semis-heavy cascade misreads the channel. Rhymes with 2019's tariff-threat episodes when MXN and Mexican equities sold off on border-closure rhetoric. Transmission: ~$800bn in annual bilateral trade and integrated auto/electronics lines mean a closure hits US autos and Mexican exporters first. Forward: an actual military strike is unprecedented, so the sovereignty/diplomatic premium in MXN would exceed any past tariff scare.

What it would mean

If this plays out, it is a risk-off shock. US military launches direct strikes on cartel targets inside Mexico, provoking a diplomatic rupture and border-trade shutdown. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · Trade tension ▲ · Risk appetite ▼ — which propagate through our causal graph to the markets below.
