SINGAPORE, June 22 (Reuters) - Middle East crude benchmarks Oman, Dubai and Murban differentials edged up amid light trading activity on Monday, while traders focused on the shipping situation at the Strait of Hormuz to assess the supply outlook.

There was a fall in ship traffic after Iran announced that it had again closed the waterway over the weekend, shipping data showed.

Global oil prices also declined after U.S.-Iran talks concluded in Switzerland with Tehran saying it had secured waivers for oil and petrochemical exports, easing worries about a supply shortage in global markets. O/R
