A what‑if from the future

What if a strike over automation snarls the port of Los Angeles?

A West Coast automation strike into peak holiday season snarls trans-Pacific imports - a domestic goods-inflation and discretionary-retail squeeze, modest for risk assets, so the small Nasdaq -0.3% and inflation-exp +0.4% are right-sized. Rhymes with the 2014-15 West Coast slowdown that jammed LA/Long Beach for months and the 2002 lockout. The US is the importer; Asian exporters feel the order backup. The forward angle is automation is the structural fault line, so like its East Coast twin this risks a longer, more inflationary standoff than priced.

What it would mean

If this plays out, it is a mixed shock. West Coast dockworkers strike over terminal automation, snarling trans-Pacific imports into peak holiday season. The trigger decomposes into signed root‑shocks — Growth surprise ▼ · Inflation surprise ▲ — which propagate through our causal graph to the markets below.
