President Joe Biden warned Israeli Prime Minister Benjamin Netanyahu the United States would not participate in a counter-offensive against Iran - an option Netanyahu's war cabinet favors after a mass drone and missile attack on Israeli territory - according to officials familiar with the development.

"The involvement on Iran has raised the geopolitical risk premium, and we expect markets to trade with a dose of caution over the coming days," Mohit Kumar, chief economist Europe at Jefferies, said in a note.

"However, beyond the near term uncertainty, we are still in buy the dip camp for risky assets and range bound environment for rates."
