Europe open: Stoxx up as investors assess expanded US sanctions on Iran

(Sharecast News) - European shares opened higher on Tuesday as investors assessed the actual structure of expanded US sanctions against Iran while Tehran pledged to retaliate against any measures that harmed its economy.

US Treasury Secretary Scott Bessent on Monday launched 'Operation Economic Outcast' and compared it with the D-Day Normandy landings in the second world war to drive the Nazis out of France.

However, the measures are not immediate, with Bessent claiming Washington was "giving everyone the opportunity to remedy bad behaviour".

"Why would I want to blow up the global financial system? We believe that it is important to level set and give people a cure period, but they should know that that will move very quickly and that we are serious," he added.

It was not clear whether the US would include China in its threatened action against countries that trade with Iran.
