NEW YORK, March 23 (Reuters) - Premiums for U.S. cash crude grades were steady to softer on Monday during the roll-trading period, dealers said, as fears of prolonged supply disruptions eased after President Donald Trump said the U.S. was in talks with Tehran about ending the U.S.-Israeli war on Iran.
Traders use a three-day roll period to adjust their crude slates, square up positions and net out exposures following the expiration of the U.S. crude futures contract.
Prices to roll U.S. crude oil futures positions from April to May traded at plus 90 cents a barrel.
Trump said on Monday there have been talks between the United States and Iran over the past day in which the two sides had "major points of agreement," adding that a deal could be done soon to settle the war.
Some grades fell as research company IIR Energy said that U.S. oil refiners are expected to have about 731,000 barrels per day of capacity offline in the week ending March 23, increasing available refining capacity by 94,000 bpd.
Capping some of the declines in cash crude prices, U.S. Energy Secretary Chris Wright told CNBC on Monday that the United States was “highly unlikely” to release additional oil from its Strategic Petroleum Reserve to calm energy markets.
