Global crude oil prices fell more than 5% in Monday morning trading as investors hoped the United States and Iran might reach an agreement to end the Middle East conflict, despite President Donald Trump signaling that no deal is imminent.
On 25 May 2026, international news agencies reported that Brent crude oil from the North Sea dropped 5.1% to $98.22 per barrel, equivalent to about 3,580 baht per barrel, in trading around 11:00 p.m. Sunday. Meanwhile, West Texas Intermediate (WTI) crude fell 5.2% to $91.57 per barrel, or roughly 3,340 baht per barrel.
The sell-off followed market speculation that the US-Iran conflict might be resolved through negotiations, even though US President Donald Trump had previously posted on social media to temper expectations for a deal, stating he had instructed US representatives not to rush, as he believed time was on the US side.
Analysts say oil prices remain highly volatile, influenced by negotiation developments and security situations in the Middle East, which remain critical factors for global energy stability. The conflict escalated on 28 February when the US and Israel launched attacks on Iran, prompting Iran to respond with missile strikes and drone attacks on regional targets.
