Crude oil has a renewed risk premium now that the US-Iran ceasefire has collapsed. Three commercial ships were attacked in the Strait of Hormuz, the US blamed Iran and struck back two days in a row, and President Trump said the ceasefire is over. The Treasury also pulled its waiver on Iranian oil sales from July 17, and Brent spiked as much as 7% toward $80. Each past crack in the ceasefire spiked oil and eventually calmed down, but nobody knows which time it won't. x.comÂ
