A Kuwait-flagged crude oil tanker was hit by an Iranian drone attack at a port in Dubai on Wednesday, with no crew injuries or oil spill reported. Brent crude surged 6.7% to $107.92 a barrel in the aftermath, according to CNBC, as the Strait of Hormuz crisis continues to choke 20% of global oil supply. Trump's primetime address the night before promised to hit Iran "extremely hard" over the coming weeks, and U.S. gasoline prices now average above $4 a gallon. Every escalation adds another dollar to the barrel, and there's no off-ramp in sight.
