US Cash Crude-Grades little changed amid hope for US-China trade deal

June 9 (Reuters) - Grades were little changed on Monday, dealers said, as investors weighed rising global supplies amid optimism around U.S.-China trade talks and a deal that could boost the global economic outlook and subsequently fuel demand.

Mars Sour WTC-MRS rose 5 cents, while WTI Midland WTC-WTM and WTI at East Houston WTC-MEH, also known as MEH, eased 5 cents each.

OPEC oil output rose in May, a Reuters survey found, although the increase was limited as Iraq pumped below target to compensate for earlier overproduction and Saudi Arabia and the United Arab Emirates made smaller hikes than allowed.

Top U.S. and Chinese officials sat down in London for talks aimed at defusing their high-stakes trade dispute, which has widened in recent weeks beyond tit-for-tat tariffs to export controls over goods and components critical to global supply chains.

The talks were set to extend to a second day and restart on Tuesday, a U.S. source familiar with the negotiations said.

Meanwhile, there is a risk that inventories at Cushing in June could be tight, analysts at Energy Aspects said, citing wildfires in the Canadian province of Alberta.

In refining news, U.S. oil refiners are expected to have about 210,000 barrels per day of capacity offline in the week ending June 13, increasing available refining capacity by 66,000 bpd, research company IIR Energy said on Monday.
