Oil price climbs above $110 as Iran talks show little sign of breakthrough

brent crude pushed above $110 a barrel on tuesday, its highest in three weeks. the white house restated its "red lines" in talks with iran, and traders saw little chance of a near-term deal that would bring more supply to market. iran negotiations have dragged on for months with no visible progress. the us has insisted on strict terms around uranium enrichment and sanctions relief, while tehran has demanded broader concessions. each side's public statements have hardened in recent days. the move adds to a rally that started after russia's invasion of ukraine disrupted global oil flows. brent is up roughly 40% since the start of the year.
