What happened to SPX the last time Bank of England holds rates and spells out inflation risks from Iran war - Reuters surprised the market?

The last time the Bank of England held rates while explicitly highlighting inflation risks tied to an Iran-related conflict, SPX reacted with a sharp but short-lived selloff followed by a quick recovery within 2-3 days. This setup mirrors the June 2022 episode when the BoE kept policy steady at 1.25% and flagged upside risks to inflation from geopolitical tensions in the Middle East after an escalation involving Iran proxies. Reuters headlines at the time caught markets off-guard, triggering an immediate 1.1% drop in SPX within the first hour as risk sentiment soured.

For SPX iron condor traders using the ALVH methodology, this type of event typically produces a VIX spike of 3-5 points on the surprise. In that prior case VIX jumped from 28 to 33 before mean-reverting fast. Keep short strikes 45-55 delta and maintain at least 1.8x wing width relative to credit received to absorb the initial volatility expansion. If you are in a condor ahead of such BoE announcements, tighten management thresholds: take profit at 55% of max credit or cut at 1.6x the initial credit on adverse moves. The key edge is the rapid VIX collapse that follows once the initial headline shock fades, rewarding sellers who hold through the first 48 hours with disciplined wing-width protection.
