Oil prices edged higher as investors assessed potential diplomatic progress after U.S. and Iranian diplomats met in New York alongside the United Nations General Assembly. Brent crude rose 0.5% but remained just below $100 a barrel, while West Texas Intermediate moved back above $90. The meeting was the first between high-level representatives from the two countries since June. U.S. President Trump described the talks as very good, while previously telling the assembly that a deal would not come until after the Midterm elections in November. U.S. stock futures and Treasury yields were largely unchanged in early European trading.
