President Trump announced at 6:02 p.m. EDT on June 23 (22:02 UTC, after the US equity close) that Israel and Iran had agreed to a phased ceasefire, which took effect June 24 and, despite initial violations that day, held into 2026. The ceasefire was mediated by the US and Qatar.

Brent next close -5.6% · +7 days -13.4% · transits 78.6 → 74.9 per day · outsized reaction — bigger than 96.2% of pre-crisis days

Attribution caveat: 1 other major event(s) sit inside this one's ±7-day window (2025-06-21 US strikes Fordow, Natanz and Isfahan (Operation Midnight Hammer)), so the reaction is not cleanly separable.
