International oil prices opened higher on Monday after Trump warned he would
strike Iran if Hezbollah continues to attack Israel, a move that raised doubts
over progress in talks between Washington and Tehran. WTI crude rose as much as
1.7%. The warning came days after Trump signed a memorandum last week launching
a 60‑day negotiation window; high‑level talks began at the Bürgenstock resort in
Switzerland. Iran said it had again closed the Strait of Hormuz, but millions of
barrels continued to transit the waterway over the weekend.
