U.S. equity benchmarks surged to fresh record highs on Friday, 17th April 2026, as geopolitical tensions eased and investors responded to confirmation that the Strait of Hormuz had been declared “completely open” during the ongoing ceasefire period.
Record high for S&P 500 above 7100 for the first time
The S&P 500 closed at 7,126.06, up 1.2% and above the 7,100 mark for the first time. The Nasdaq Composite extended its remarkable winning streak to 13 consecutive sessions, finishing at 24,468.48, a 1.52% gain and its longest run since 1992.
The Dow Jones Industrial Average also rallied sharply, jumping 868.71 points (1.79%) to end at 49,447.43. The Russell 2000 hit new highs too.
The rally followed Iran’s announcement that commercial passage through the Strait of Hormuz was fully open under ‘coordinated’ routes, easing fears of supply disruption.
Oil prices tumbled in response: WTI crude oil fell nearly 12% to $83.85, while Brent dropped 9% to $90.38.
Sector‑level moves reflected a broad risk‑on shift. Travel‑exposed stocks such as airlines and cruise operators rebounded, while major technology names also advanced.
Market strategists suggested investors were “moving beyond this conflict” as worst‑case scenarios were reassessed.
Assuming the ‘news’ is to be believed. No intent is suggested.
With all major indices setting new highs, Friday’s session underscored how quickly sentiment can pivot when geopolitical uncertainty recedes — even temporarily.
This market move was ultimately led by a social media post by President Trump on Truth Social.
