A what‑if from the future

What if simultaneous droughts sparked a global grain shortage?

Synchronized droughts cutting wheat/corn yields feed straight into food CPI and inflation-fragile EM FX, with a secondary gas/fertilizer link via heat-driven power demand. The defining rhyme is the 2010-11 Russian heat-wave/export-ban grain spike that fed the Arab-Spring food-price surge, and the 2012 US Midwest drought. Forward angle: today's larger global stocks-to-use buffer and Black Sea normalization cap the upside versus 2010 — fade parabolic grain unless multiple breadbaskets fail at once; the EM-FX inflation leg is the more reliable trade.

What it would mean

If this plays out, it is a mixed shock. Simultaneous droughts cause a global wheat/grain shortage and a food-price crisis. The trigger decomposes into signed root‑shocks — Climate/crop supply ▲ — which propagate through our causal graph to the markets below.
