In this trading session, fuel prices remained under pressure due to investor reaction to recent progress toward peace in the Persian Gulf. Iran held talks during the afternoon with Saudi Arabia and Oman regarding the situation in the Strait of Hormuz and diplomatic solutions to the crisis.

US President Donald Trump stated that this is "a good time" for the Persian country's administration to reach a nuclear agreement with Washington. He declared that Tehran has "essentially" agreed not to develop nuclear weapons, but stressed that the process has not yet been properly formalized.
