Oil Prices Surge as Shipping Attacks Intensify

Oil prices increase as attacks on shipping ramp up

Brent crude climbed 2.5% to $113.51 a barrel Thursday, moving close to the four-year high reached earlier this year as tensions surrounding the Iran conflict continued to weigh on energy markets.

The latest increase places Brent near the upper end of its range since the war began on Feb. 28, when the first U.S.-Israeli strikes on Iran were reported. Brent reached $114.44 a barrel on May 4, according to the information provided, and touched $114 in early trading on Oct. 23.

U.S. West Texas Intermediate crude also moved above $100 a barrel on Oct. 23. The rise in both benchmarks reflects continued concern about the security of oil shipping routes and the possibility of further military action in the region.

A sustained price premium

Data from the U.S. Energy Information Administration shows how significantly the conflict has changed the oil market. Brent averaged just over $100 a barrel from the start of the war through the period covered, compared with about $69 in January and February.

That difference of roughly $31 a barrel represents an increase of about 46% over the average price before the conflict began.

The initial market reaction was sharp. Brent averaged $103.13 a barrel in March, up from $70.89 in February. The monthly average reached $117.29 in April before prices eased during the summer. July recorded the lowest monthly average since the war began, at $83.76 a barrel.

Prices have since moved higher again. Brent was reported at $125.44 a barrel on Oct. 6, up 87% from $67.09 a year earlier. The average for 2026 through that point was listed at $93.81, compared with $69.14 for all of 2025.

Shipping routes remain central to the market

The Strait of Hormuz remains a key focus for the oil market. Reports cited in the supplied information say the volume of oil moving through the strait has exceeded prewar levels despite continuing regional tensions.

At the same time, energy analytics firms Kpler and Vortexa reportedly estimated that Iran’s seaborne crude exports fell to zero in September and October because of U.S. sanctions and naval blockades.

Those developments show the mixed nature of the current supply picture. Oil is still moving through one of the world’s most important shipping corridors, but restrictions on Iranian exports and concerns about renewed military action are adding risk to the market. Traders often price that risk into crude contracts before any direct change in supply occurs.

Brent rose more than 3% on Oct. 22 to move above $112 a barrel, followed by the advance to about $114 the next day. The market then remained close to those levels as reports circulated about possible U.S. and Israeli plans for a short, intensive operation after next month’s midterm elections. The supplied information does not establish that such an operation will occur.

What higher oil prices mean for truck drivers

For professional drivers and small carriers, crude oil is an important indicator of pressure that can eventually reach the diesel market. Higher crude prices raise the cost of producing and distributing fuel, although pump prices do not always move at the same speed or by the same amount.

Fuel is one of the largest variable expenses in trucking. When diesel prices rise, the effect is felt most quickly by owner-operators and fleets running long miles, especially those operating under fixed-rate contracts or with fuel surcharges that lag behind market changes.

Higher fuel costs also increase the importance of route planning, idle reduction and accurate trip budgeting. A load that appears profitable when it is booked can produce a smaller margin if fuel prices rise before the trip is completed. Carriers may also face additional uncertainty when international shipping disruptions affect freight volumes, port activity or delivery schedules.

The latest oil increase does not by itself confirm a shortage of fuel for North American truckers. However, it indicates that energy markets continue to carry a substantial conflict-related premium. Brent’s 2026 average remains well above last year’s level, and prices are still near the high end of the range recorded since the war began.

For drivers, the immediate issue is not the headline price of crude alone. It is how long elevated prices persist and how quickly changes flow through to diesel, fuel surcharges and freight rates. With tensions continuing around Iran and major shipping routes, the oil market remains sensitive to new developments.
