What it would mean

If this plays out, it is a mixed shock. Flooding and saltwater intrusion across the Mekong and other Asian deltas cut rice output and displace populations, the chronic-and-acute climate channel the ADB and IMF flag for regional food supply. The trigger decomposes into signed root‑shocks — EM currencies ▼ · Climate/crop supply ▲ · Food inflation ▲ · Recession signal ▲ — which propagate through our causal graph to the markets below.
