Major US equity indexes fell for a third consecutive week: their longest losing streak in about a year, as the Iran war entered its second week with no resolution in sight and Brent crude broke above U$100/bbl for the first time since August 2022. The S&P 500 declined roughly -1.6%, the Dow shed -2%, and the Nasdaq dropped -1.3%, with the S&P closing at a new 2026 low.
