European aerospace stocks are suffering some of their biggest weekly losses in years on concerns that fuel prices will stay high due to the Iran war, curbing air travel demand and eroding profits.

Safran SA, which makes engines and components for aircraft and helicopters, is heading for its worst weekly share-price performance since 2022, tumbling about 14%. Germany’s MTU Aero Engines AG has slumped 17%, putting it on track for its steepest drop in six years.
