Oil prices soared to their highest since 2008 due to delays to the conclusion of Iranian nuclear talks and the potential return of Iranian crude to global markets, which are already suffering from Russian supply disruptions, analysts said.
Talks to revive Iran's 2015 nuclear deal with world powers were mired in uncertainty on Sunday following Russia's demands for a U.S. guarantee that the sanctions it faces over the Ukraine conflict will not hurt its trade with Tehran. China has also raised new demands, according to sources.
In response to Russia's demands, U.S. Secretary of State Antony Blinken said on Sunday that the sanctions imposed on Russia over its Ukraine invasion have nothing to do with a potential nuclear deal with Iran.
