International oil prices increased again as negotiations between the United States and Iran over Tehran’s uranium stockpile and the Hormuz Strait remained deadlocked. According to an Al Jazeera report cited on May 22, 2026, investor uncertainty over the lack of progress in the talks contributed to the price surge. On Friday, the global benchmark Brent crude rose by 2.3 percent, or 2.38 dollars, reaching 104.96 dollars per barrel.

At the same time, the price of US West Texas Intermediate (WTI) crude increased by 1.8 percent, or 1.73 dollars, to 98.08 dollars per barrel. The rise followed a nearly 2 percent drop in both benchmarks on Thursday, which had brought prices to their lowest level in about two weeks.

The report indicates that the continuing diplomatic stalemate between Washington and Tehran is keeping investors cautious, with energy markets responding to the uncertainty surrounding the region and its potential impact on global oil supply routes.
