Stocks Drop, Oil Jumps After Trump Says Ceasefire with Iran Is "Over" | Bloomberg Brief 07/08/2026
Context
US equity futures slump and oil extends gains as President Trump says a tentative ceasefire with Iran is over. The US had struck 80 sites in Iran ahead of the president's remarks at the NATO Summit in Ankara, Turkey. Mark McCormick of BMO Capital Markets discusses the impact of fresh geopolitical tensions.

What it means
The collapse of the US-Iran ceasefire and confirmation of US strikes on Iranian soil represent a genuine escalation — not a continuation — and have historically been associated with sharp spikes in oil prices and gold as a safe haven, alongside a meaningful pullback in US equities. Airline stocks face additional pressure from rising fuel costs. The prior signals in this series covered NATO defense spending; this is a distinct, new shock channel centered on crude supply risk and broad risk-off sentiment.
