Brent Crude Nears $89 as Strait of Hormuz Traffic Halts Amid Iran-US Tensions

Oil markets opened Monday with a familiar tension: prices holding steady on the surface while something more volatile churned beneath. Brent crude was trading near eighty-nine dollars a barrel, West Texas Intermediate near eighty-three, both up fractionally—gains that felt almost negligible until you looked at what had driven them. Last week, crude had surged more than five percent after reports of attacks on tankers in the Persian Gulf. The question now was whether that spike would hold, or whether the real shock was still coming.

The Strait of Hormuz, the narrow waterway through which roughly a third of the world's seaborne oil passes, had become a bottleneck in the most literal sense. Vessel traffic through the passage had collapsed over the weekend. On Saturday, according to shipping data from Kpler, only five commercial vessels crossed the strait. On Sunday, none did. The previous weekend had seen thirty-one crossings. The difference was not a matter of weather or mechanical failure. It was fear.

That fear had a name and a deadline. A memorandum of understanding between the United States and Iran, signed in June after negotiations brokered by Pakistan, was set to expire on Monday. The agreement had been contentious from the start—Washington and Tehran each accused the other of violations, each questioned whether the other was negotiating in good faith. Now, with the expiration date at hand, neither side had signaled any willingness to extend it. Iranian Foreign Minister Abbas Araghchi said on Saturday that Tehran had not yet decided whether to resume talks with Washington. The same day, US President Donald Trump had vowed to impose severe economic pressure on Iran. The language of diplomacy was giving way to the language of confrontation.

Peter McGuire, chief executive of Trading.com's Australia office and a veteran observer of global energy markets, framed the stakes plainly when he spoke to Times Now Digital. Tempers were rising, he said. The United States was not backing down. The stakes were climbing. The impact on oil supplies would be felt most acutely in Asia—in China, Japan, and India—where demand for crude was highest and alternatives were fewest. He advised a wait-and-watch posture, a recognition that the next moves by Washington and Tehran would determine whether Monday's marginal price gains were the beginning of something larger.

What made the moment precarious was the arithmetic of global oil supply. The Strait of Hormuz is not one route among many—it is the route. Disruptions there do not merely affect prices at the pump; they ripple through shipping schedules, refinery operations, and the energy security calculations of nations that depend on steady crude flows. A weekend in which nearly all traffic stopped was a warning. If the memorandum expired without renewal, if tensions escalated further, the question was not whether prices would rise. It was how far, and how fast, and whether the world's economies could absorb the shock.
