Following the results of last week, oil showed growth: Brent grew by 0.7%, WTI - by 1.3%. On Friday, oil also showed growth as the timing of consideration of the US participation in the agreement on Iran's nuclear program approached. If the US withdraws from this agreement, concluded in 2015, and the restriction on the export of Iranian oil will be carried out, this could lead to a fuel shortage in the world market. In this case, according to the experts, this year Iran will reduce oil supplies by about 500 thousand barrels per day. The price of July futures for Brent crude by 18:18 Moscow time on Friday increased by 64 cents to 74 dollars 26 cents per barrel. June futures for WTI rose 52 cents to 68 dollars 95 cents per barrel.
