Trump Weighs Iran Strikes as Oil Prices Surge
By Drooid · · How we work
Background: Conflict and Market Sensitivities
The United States and Israel began a war against Iran on Feb. 28, prompting Iranian attacks on commercial shipping that have reduced traffic through the Strait of Hormuz to a fraction of pre-war levels. From late September through early October, daily vessel traffic in the strait averaged fewer than 23 ships, down from hundreds per day before the conflict. Analysts have warned that any escalation—particularly a large-scale U.S. strike—could push oil prices higher.
Market Reaction: Prices, Yields, and Stocks
On Thursday, Brent crude rose more than 5 % to above $105 per barrel, while U.S. crude (WTI) climbed nearly 5 % to around $93 per barrel. Diesel futures jumped 4.5 % in European trading, and heating-oil prices rose over 4 %. The rally lifted Treasury yields; the 10-year Treasury yield spiked to 5.35 %, reversing a prior decline. Equity markets fell, with the S&P 500 down 0.4 %, the Nasdaq down 0.6 %, and the Russell 2000 slipping almost 1 %.
Supply Disruptions: Gulf of Mexico Storm and Strait of Hormuz
Two supply shocks compounded the price surge. Tropical Storm Isaias forced producers in the Gulf of Mexico to shut in more than 510,000 barrels per day—about a quarter of regional output—as offshore personnel were evacuated. Ongoing attacks on tankers in the Persian Gulf halted a tentative recovery in exports from Gulf Cooperation Council members, keeping forward-curve supplies tight.
Official Statements & Responses
President Donald Trump signaled that diplomatic talks with Tehran were “productive” and asserted that the United States would not strike Iran before the upcoming midterm elections. A separate report indicated that the White House asked the Pentagon to draft strike options that could be executed before the elections, though the size and targets of any operation remain under debate. U.S. Central Command posted that 20 million barrels of crude were flowing through the Strait of Hormuz—a figure that matches pre-conflict daily volumes but lacks an explicit timeframe.

Conflicting Reports & Gaps
U.S. Central Command’s claim of 20 million barrels per day flowing through the Strait of Hormuz is not corroborated by other sources, which have reported reduced traffic and lower vessel counts. No independent data have been provided to verify the flow figure or its timing, leaving a gap in understanding the actual volume of oil transiting the strait amid the conflict.
What’s Next
Analysts project that if skirmishes curbing oil flows persist through the end of the year, Brent could trade in a $95-$120 range, with spikes possible should a broader conflict damage major energy infrastructure. Market participants will watch for any official decision on U.S. strike options before the midterm elections, as well as the evolution of storm-related shutdowns in the Gulf of Mexico.
