Iran is located on the northern side of the Strait of Hormuz and could block most oil exports from Iraq, Kuwait, Saudi Arabia and smaller Gulf states if it wanted to.

«The attack came at a critical time when macroeconomic and systematic funds have regained long positions and investor sentiment has become optimistic again,» quoted by Bloomberg strategist IG Tony Sycamore. - As we wait for further news and a possible response from Iran, we can assume a further deterioration in risk appetite as traders reduce risk positions ahead of the weekend.»
Context
The Israeli airstrike on Iran was preceded by disagreements between U.S. President Donald Trump and Israeli Prime Minister Benjamin Netanyahu over negotiations on a new agreement on Iran's nuclear program, wrote The New York Times.
Since April, the U.S. and Iran have held five rounds of indirect talks, with the sixth set for June 15. The key contentious issue at the talks is uranium enrichment. The US has declared that it will not allow Tehran to enrich uranium and will demand the complete dismantling of Iran's nuclear facilities. For its part, Iran insists it will not sign an agreement banning uranium enrichment for civilian purposes.
Netanyahu in turn suggested the use of military force against Iran. Two weeks ago, Trump called to refrain from any forceful action while negotiations continue. On June 11, Trump said he was becoming less confident that Iran would agree to stop enriching uranium. On June 12, he warned that a potential Israeli attack on Iran would likely destroy the chances of a diplomatic solution.
