U.S. oil futures settled slighted higher on Tuesday as traders continued to watch developments tied to talks aimed at reviving the Iran nuclear deal. The market weighed the likelihood and timing of a prospective deal that would lead the U.S. to lift sanctions on Iran, allowing it to contribute more oil to the world market. West Texas Intermediate oil for July delivery inched up by 2 cents, or 0.02%, to settle at $66.07 a barrel on the New York Mercantile Exchange, with prices for the front-month eking out another settlement at the highest since May 17, according to FactSet data.
