This morning the New York futures for Brent increased 0.18% to $ 56.91 and WTI rose 0.28% to $ 53.97. Thus, the price of black gold traded higher due to the weakening of the dollar, as well as fears that the introduction of new US sanctions against Iran can affect the export of Iranian oil. Tensions between the US and Iran began after the launch of a ballistic missile. United States on Friday imposed sanctions on 13 people and 12 companies linked to Iran.
