Oil slides as US–Iran talks resume and tariffs cloud demand

Oil prices slipped about 1% as the US and Iran prepared for a third round of nuclear talks in Geneva, easing fears of conflict, while Trump’s tariff hike added growth-uncertainty that weighed on demand. Brent traded around $70.89 a barrel and WTI around $65.63, with analysts noting an Iran risk premium but potential sanctions relief that could boost supply; Goldman Sachs also warned of downside risk to 2026 prices if sanctions relief or other disruptions accelerate supply, though a global surplus is forecast if none materializes.
