Line chart showing WTI crude oil climbing above 100 dollars a barrel amid the Strait of Hormuz conflict.

WTI crude has climbed roughly 51 percent since early July as the Strait of Hormuz conflict enters its third month, with commercial shipping through the strait reduced to a handful of vessels a day. The United States has redirected, disabled, or boarded dozens of vessels enforcing its blockade of the strait. Elevated oil prices are now a documented input into a Federal Reserve rate decision, not only a story for energy markets, though a full closure of the strait remains a tail risk rather than the base case.
