Updates prices, adds Saudi production and exports at record lows

LONDON, May 20 (Reuters) - Oil prices lost more than 2% on Wednesday after U.S. President Donald Trump again asserted that the Iran war will end "very quickly", though investors remain wary about the outcome of peace talks as disruption to Middle Eastern supply continues.

Brent crude futures LCOc1 fell $2.58, or 2.3%, to $108.70 a barrel by 1211 GMT and U.S. West Texas Intermediate futures CLc1 were down $2.07, or 2%, at $102.08. Both contracts were heading for their biggest daily drops in percentage and absolute terms in two weeks.

"Prices are likely to still exhibit some upside potential even if a deal is concluded, given that supply will likely not return to pre-war levels immediately," said LSEG research analyst Emril Jamil.

Both benchmarks fell nearly $1 on Tuesday after U.S. Vice President JD Vance said that the U.S. and Iran had made progress in talks. But Trump also said that the United States may need to strike Iran again and had been an hour away from ordering an attack before its postponement.

Analysts at Citi said on Tuesday that it expected Brent crude to rise to $120 a barrel in the near term, stating that oil markets are underpricing the risk of prolonged supply disruption, and Wood Mackenzie estimated that it could approach $200 if the Strait of Hormuz stays largely shut until the end of the year.

Similarly, PVM analysts said global oil stocks could reach critically low levels. "Yet, as observed lately, market players are comparatively nonchalant (or complacent) about what the conflict might bring," PVM said.

The premium on Brent contracts for delivery next month over contracts for delivery in six months LCOc1-LCOc7 - an indicator of traders' views of current supply tightness - is around $20 a barrel, way below last month's highs above $35.

Three supertankers were crossing the Strait of Hormuz on Wednesday, carrying oil bound for Asian markets, after waiting in the Gulf for more than two months with 6 million barrels of Middle East crude on board. The number of vessels crossing the strait remains well below the 130 or so ships that crossed daily before the war.

To make up the supply shortfall, countries are relying on commercial and strategic inventories.

In other signs of the increasing supply crunch, Britain has watered down sanctions to allow imports of diesel and jet fuel refined abroad from Russian crude.

Saudi Arabia's crude oil exports and production dropped to record lows in March, data showed.
