US strikes Fordow, Natanz and Isfahan (Operation Midnight Hammer)

2025-06-21 23:50 UTC · military · major

The United States struck Iran's three main nuclear sites with B-2-delivered GBU-57 bunker-busters and submarine-launched Tomahawks; President Trump announced the strikes at about 7:50 p.m. EDT Saturday (23:50 UTC June 21), with bombs on target roughly an hour earlier. Widely datelined June 22 because the strikes occurred overnight Iran local time; markets were closed for the weekend, with the first trading reaction at the Sunday evening futures open.

Brent next close -5.6% · +7 days -11.9% · transits 84.7 → 71.0 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 (2025-06-23 Trump announces Israel-Iran ceasefire ending the Twelve-Day War), so the reaction is not cleanly separable.
