Prices continue to remain elevated, due to the launched joint strikes by the United States and Israel, in an initiative geared towards halting Iran’s development of nuclear weapons.

Various reports cited declining oil prices early last week, after a preliminary agreement was reached between the U.S. and Iran.

EIA officials said that the Strait of Hormuz handles about 20% of the world’s petroleum supply (roughly 20 to 21 million barrels per day) and about 20% of global liquefied natural gas (LNG). It added that due to recent conflicts, this vital energy chokepoint has experienced significant blockades and military standoffs, leading to major global supply disruptions and price volatility.

Patrick De Haan, a petroleum analyst at GasBuddy, wrote in a series of social media posts that the preliminary deal led to a 5% decline in oil prices yesterday, adding that gas stations will start lowering prices this week, following that decline, which could take up to a week or two to pass on, with that caveat that things, “could quickly reverse if the deal unravels.”
