Oil Prices Fall Sharply on Renewed Hopes for US-Iran Nuclear Accord

Oil prices fell sharply Wednesday, May 27, 2026, as investors anticipated a potential US-Iran deal that could lift sanctions and expand global crude supply. Brent crude dropped 4.2% to $68.30 a barrel, while U.S. benchmark West Texas Intermediate slid 4.5% to $64.55 — the steepest single-day decline in three weeks. The selloff followed reports that Washington and Tehran agreed to resume indirect talks in Vienna this weekend, reviving a stalled diplomatic push. Analysts said a breakthrough could restore over 1 million barrels per day of Iranian exports within months, piling onto already well-supplied markets. "The prospect of a deal removes a geopolitical risk premium," said Helima Croft, head of commodity strategy at RBC Capital Markets. The slide in crude futures rippled through equity markets, weighing on energy-sector shares while easing inflation fears that have dominated bond trading. Traders now await the June 4 OPEC+ meeting, where the group may reassess output cuts in light of potential Iranian re-entry.
