WASHINGTON — brent oil price rose on Monday after Iran and the U.S. ruled out extending a memorandum of understanding signed on June 17, with the international benchmark settling at $90.87 per barrel, up 2.7%, according to CNBC.
Fortune also reported that as of 6 a.m. Eastern Time today, oil sold for $91.53 per barrel using Brent as the benchmark, up 86 cents from yesterday morning and about $25.65 higher than a year earlier. The move matters because Brent is the global reference price that helps shape costs well beyond crude markets.
Deal deadline puts pressure on crude
The agreement, signed on June 17, was set to expire Monday. Iran’s Foreign Ministry ruled out talks to extend the memorandum, according to the state news agency Tasnim, while President Donald Trump later said he was not interested in extending the deal, CNBC reported.
A senior Iranian official told Reuters that Tehran would shift to offense rather than relying on defense if diplomacy with the U.S. fails. The official said, “Iranian entities must be prepared to escalate tensions in the Strait of Hormuz and wider region, as Iran will be ready to make decisions and take action on difficult decisions,” according to CNBC’s report.
That is where the market gets nervous. The Strait of Hormuz sits at the center of the shipping route tied to Middle East supply, so any fresh tension tends to show up quickly in crude prices. Traders do not need a shutdown to react. The possibility alone can move barrels.
What consumers feel when Brent moves
Brent oil price changes flow through to gasoline and other fuels, though not in a simple straight line. Fortune noted that when people pay at the pump, they are paying for more than crude itself. Refiners, wholesalers, taxes and local station markups all sit in the chain.
Still, the crude portion has the biggest impact. Fortune said it typically accounts for more than half the price per gallon, which is why a sharp jump in oil can push fuel costs higher. When prices fall, pump prices usually lag on the way down. Fast on the way up. Slow on the way back.
That dynamic makes Monday’s move more than a traders’ headline. It can feed into transportation costs, delivery bills and the price of goods that depend on fuel. For businesses that run fleets or heavy logistics networks, every move in the benchmark matters.
Why the market is watching Hormuz
CNBC reported that the memorandum of understanding between the U.S. and Iran was meant to open the Strait of Hormuz while negotiations on Tehran’s nuclear program continued within 60 days. The U.S. and Iran agreed to that framework on June 17, but the sides have now rejected an extension.
Iran’s Foreign Ministry spokesman, Esmail Baghaei, said the country would not extend the deal. “We did not start any negotiations at all, and the U.S. violated the understanding from the very beginning; therefore, the 60-day issue is not relevant,” he said, according to Tasnim.
President Donald Trump also pressed the issue sharply in remarks to Fox News and later to reporters, according to CNBC. The combination of expired terms, public defiance and rhetoric around Hormuz kept crude traders focused on supply risk rather than demand alone.
For now, the market is trading that tension in real time. Brent closed at $90.87, and the morning quote sat at $91.53 a barrel. That gap may look small. Traders know it can widen quickly if the standoff hardens.
