Brent jumped to $88.10 on 17 July after Iran struck a Kuwaiti power plant. By 20 July, after nine nights of US strikes on Iran, Brent topped $90 and West Texas Intermediate (WTI) reached $84.38.
The gap between the two prices widened to $5.61 and held there. Sea-based Brent keeps rising faster than land-locked WTI, because ships, not pipelines, carry the Hormuz risk.
