What if Panama Canal low water and Black Sea risk snarl grain-logistics chokepoints together?
A drought-driven Panama Canal or Mississippi low-water event plus Black Sea risk snarls grain logistics, raising freight and delivered food costs and tightening regional supply, a logistics-shock scenario.
Every number ships with its receipt — the odds, the range, the precedents, and a public grade at Reality Check. The statistical machinery that produces it is proprietary.

Resolution timeline — how this probability is moving
Our model's odds (electric blue) over time vs the market's (Polymarket, amber), 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. Loading the probability audit trail…
What it would mean
If this plays out, it is a mixed shock. A drought-driven Panama Canal or Mississippi low-water event plus Black Sea risk snarls grain logistics, raising freight and delivered food costs and tightening regional supply, a logistics-shock scenario. The trigger decomposes into signed root‑shocks — Corn ▲ · Wheat ▲ · Climate/crop supply ▲ · Food inflation ▲ — which propagate through our causal graph to the markets below.
