Oil Prices Rise Amid Geopolitical Tensions and Market Reactions

Diesel prices have increased due to recent escalations in the Russia-Ukraine war. President Donald Trump announced that the United States would not resume airstrikes against Iran before the midterm elections, which did not prevent a significant rise in oil prices on Thursday. Trump stated on his social media site, "We will not be attacking Iran at any time prior to the Midterm Elections to be held in the United States on November 3rd," adding that the U.S. was having "productive discussions with the Islamic Republic of Iran." Despite this announcement, oil markets largely disregarded it after a brief dip. Brent crude oil rose to nearly $106 per barrel before closing at $104.28, a 4% increase. U.S. crude oil ended the session up 3.6% at $91.49, after peaking at nearly $93. Other energy prices also increased, with benchmark diesel futures spiking 6% in European trading and heating oil rising more than 5%. The rise in oil prices is attributed to concerns over Iranian proxy attacks in Saudi Arabia and the impact of Hurricane Isaias, which led to the suspension of work at several oil rigs in the Gulf of Mexico. Trump's announcement followed reports that he was considering strikes on Iran before the midterms, although it was noted that he had not made a final decision. Following Trump's post, key bond yields dropped, with the 10-year yield falling to its lowest level since Friday. Stocks experienced choppy trading but were largely unaffected by the announcement, with the S&P 500 closing down 0.5% and the Nasdaq Composite falling 1.2%. The ongoing Iranian attacks on commercial shipping have significantly reduced traffic through the Strait of Hormuz, a vital route for global oil supplies. From September 28 to October 4, daily traffic in the strait averaged fewer than 23 ships, compared to hundreds before the war. Experts have warned that any escalation in the conflict could lead to higher oil prices, with predictions suggesting Brent could trade between $95 and $120 per barrel. The cost to ship crude oil from unaffected countries has also surged, with the price for a crude carrier to move U.S. oil to Asia reaching $77 million, compared to $9.2 million in 2025. The rise in crude oil prices has kept retail gas prices high for U.S. consumers, with the national average for regular unleaded gas at $4.36 per gallon, over 45% higher than when the war against Iran began on February 28. Diesel fuel prices have increased even more, reaching $6.28 per gallon, a nearly 70% rise since February 28.
