[Crude Oil Futures Prices Rise Due to Uncertainty in Negotiation Prospects] Reported by Golden Finance, on April 21, crude oil futures prices rose as the market remained unclear about whether Iran would send a delegation to Pakistan for talks with the United States. Phil Flynn of Platts Futures Group stated in a report that the conflicting signals sent by Iran are not 'random diplomatic theatrics' but rather indicate an internal struggle between the pragmatic faction attempting to ease tensions and the hardliners. For the oil market, this suggests that prices will become more volatile.
