Oil prices in Asian trading on Monday fell, with investors focusing on diplomatic efforts to end the war between the United States and the Islamic Republic, continuing the downward trend from last week.

Brent crude fell 1.25% to $102.57 per barrel, while West Texas Intermediate crude also traded down 1.53% at $98.77.

Signs of potential diplomatic progress and efforts to restore disrupted oil supply from Saudi Arabia have reduced market concerns about a supply shortage.

Donald Trump, the U.S. president, told Fox News that he is likely to be prepared to meet Massoud Pezeshkian, the president of the Islamic Republic, on the sidelines of the United Nations General Assembly. Any likely progress in the talks could reduce pressure from geopolitical tensions on the oil market.

However, the Houthis’ attacks on Saudi Arabia and disruptions to the country’s east-to-west pipeline line continue to raise concerns about oil exports. At the same time, reports about the transfer of additional Saudi oil cargoes near Sohar Port in Oman have reduced worries about an immediate supply shortage.
