What if China extends its phosphate export halt?
China extending its phosphate/DAP export suspension prolongs the fertilizer squeeze into planting — long phosphate (Mosaic, Nutrien) and a farmer-margin hit; the Nasdaq/semis/yuan trade-war cascade is misattributed to a fertilizer-supply story. Rhymes with China's 2021-22 phosphate curbs that spiked DAP and pressured Indian/Brazilian buyers. Transmission: India and Brazil scramble for Moroccan/Saudi DAP, lifting global prices. Forward: China is the swing phosphate exporter, so prolonged curbs structurally re-rate the cost curve into the next crop cycle.

What it would mean
If this plays out, it is a mixed shock. China extends its phosphate and DAP export suspension past August 2026, prolonging the global fertilizer squeeze into the next planting season. The trigger decomposes into signed root‑shocks — Fertilizer cost ▲ · Food inflation ▲ · Trade tension ▲ — which propagate through our causal graph to the markets below.
