WTI crude jumped to $77.83 a barrel shortly after 5 a.m. ET Thursday, a 3.5% intraday spike, after Yemen's Houthis claimed a new attack on a Saudi tanker in the Gulf of Aden. Prices eased back toward $75 by late morning as Iran and Oman moved a narrower shipping-route agreement, covering two to four months and explicitly short of a full reopening, into final drafting. The whipsaw underscores that the broader Strait of Hormuz standoff behind this week's market moves has not actually been resolved.
