Reports indicate the US and Iran have struck a tentative deal, easing the most acute geopolitical risk overhang in the Middle East and triggering a broad rally in global equities. Oil prices fell on the news as a de-escalation removes the conflict-driven supply-disruption premium that had been embedded in crude, while equity markets priced in a lower geopolitical risk environment across sectors.

The key unknowns are whether this deal holds, what the specific terms are regarding Iranian oil supply returning to market, and how quickly sanctions relief could follow. Watch crude benchmarks (Brent/WTI), defense names, and energy sector ETFs — the setup creates a potential sustained headwind for oil and a tailwind for risk assets, but headline reversals in Middle East diplomacy are historically common and could snap back quickly.
