Line chart showing Brent crude oil easing 1.38 percent to 93.09 dollars a barrel ahead of new U.S. sanctions on Iran.

The US Treasury unveils its toughest Iran sanctions yet today, targeting countries still purchasing Iranian oil rather than Iran directly, and China bought more than 80% of Iran's shipped oil in 2025, making Beijing's response the real determinant of whether the sanctions have teeth. Brent eased into the announcement rather than rallying ahead of it, matching the pattern of prior sanctions rounds a former US negotiator called largely exhausted. Canadian energy producers benefit either way from any sustained price floor above 90 dollars a barrel.
