A what‑if from the future

What if the PBOC devalues the yuan past 7.5 to the dollar?

A managed-yuan break past 7.5 exports deflation and triggers an Asian-FX domino: the cleanest trade is short copper and China megacaps as the devaluation signals demand weakness, with an AUD and KRW/TWD selloff alongside. Direct rhyme is the August 2015 CNY 'reform' devaluation and the August 2019 break of 7 that earned the manipulator label and a global risk-off. Forward: a weaker starting growth base means deflation export bites trade partners harder than 2015.

What it would mean

If this plays out, it is a mixed shock. The PBOC engineers a sharp managed-yuan devaluation past 7.5, exporting deflation and triggering an Asian-FX domino selloff. The trigger decomposes into signed root‑shocks — China growth ▼ · Trade tension ▲ — which propagate through our causal graph to the markets below.
