World oil prices slipped modestly Tuesday amid tentative optimism over U.S.-Iran diplomatic efforts, with Brent crude hovering near $94.70 per barrel as traders weighed mixed signals from the Middle East against lingering threats to global energy supplies.
Brent crude futures, the international benchmark, traded around $94.63 to $94.88 per barrel in early European trading on April 21, 2026, down roughly 0.8% from the previous session's close. U.S. West Texas Intermediate crude fell similarly to about $86.60 to $86.70 per barrel. The modest decline followed a sharp 5-7% surge the day before on renewed uncertainty over ceasefire prospects and shipping disruptions in the Strait of Hormuz.
