On September 8, 2026 (local time), the first trading day after the Labor Day holiday, the New York stock market closed with widespread declines. Houthi rebels, an Iran-backed armed group in Yemen, attacked Saudi Aramco facilities and air force bases, causing international oil prices to surge to levels threatening to break the $100 per barrel mark, which in turn reignited inflation concerns. New York index futures also showed weakness across the board, increasing market tension.
