The August contract of WTI crude oil negotiated in New York Mercantile Exchange (Nymex) closed this Tuesday (14) with a strong increase of 1.53%, quoted at US$ 79.34/barrel. The September contract of Brent advanced 1.72% in Intercontinental Exchange (ICE), trading at US$84.73/barrel. Both contracts reached their highest values since June 12.

In this trading session, fuel prices continued to be impacted by the escalating hostilities between the United States and Iran, reigniting market fears about the flow of energy produced in the Persian Gulf. 

On the eve (13), after an exchange of attacks between the countries, US President Donald Trump reinstated the naval blockade of Iran.

However, the gains were limited after Trump stated that he had abandoned the proposal to charge a 20% tariff on ships passing through the route. 

To alleviate market concerns, the US president declared that he had met with the Iraqi Prime Minister, Ali al-Zaidi, stating that energy-related agreements would be reached with the country.
