Brent crude moves below $80 a barrel for the first time in more than three months as markets price in the prospect that a pending U.S.-Iran agreement will reopen the Strait of Hormuz and restart oil flows. Multiple outlets report Brent North Sea crude drops about 4% Tuesday, trading just under the $80 threshold—around $79.87 to $79.99—before some reports note a slight rebound to near $80. Optimism is tied to statements that the strait would “completely open” once the U.S. and Iran sign their peace agreement, with signing expected after negotiations in Switzerland. Several sources link the price move to earlier disruptions in tanker traffic during an escalation that included U.S. and Israeli strikes in late February. Traders focus on near-term supply expectations, while also watching for risks that Iran could impose “service fees” or tolls on ships transiting the waterway, which could partially offset the benefits of reopening. Alongside crude, other gauges in the energy complex—including U.S. West Texas Intermediate futures, gasoline prices, and broader market commentary—also decline as sentiment shifts toward easier supply conditions.
