What if a short-volatility blow-up sends the VIX soaring again?
A short-vol/structured-product blowup is the cleanest mechanical cascade in the book: a violent VIX spike detonates vol-target and risk-parity books, dumping Nasdaq, tech and semis, blowing out HY credit and dragging MSTR/BTC. This is Feb 2018 Volmageddon (XIV to zero) almost literally. Forward angle: the buffer/defined-outcome ETF and dispersion-short complex is far larger today than the 2018 VIX-ETP stack, so the dealer-gamma feedback can overshoot the original episode.

What it would mean
If this plays out, it is a risk-off shock. A short-volatility / structured-product blowup spikes the VIX violently. The trigger decomposes into signed root‑shocks — Volatility (VIX) ▲ · Risk appetite ▼ — which propagate through our causal graph to the markets below.
