Oil Prices Mixed as G7 Reserve Release Plans Meet Middle East Risks

Front-month WTI crude oil futures fell 0.76% to trade at $90.42 per barrel in early Monday trading, according to live price data, while the global Brent benchmark rose 0.45% to $102.71, highlighting a diverging market sentiment.

The primary pressure on U.S. benchmark prices came from a coordinated government stockpile release announced by G7 nations. On Friday, the group pledged to release 100 million barrels of crude oil and diesel from strategic reserves over the next four months, according to OilPrice.com. The plan includes a "frontloaded substantial diesel release" within the first 20 days. However, Japan, a key G7 member, stated on Monday it has "no plans for a further release at this stage," with Chief Cabinet Secretary Minoru Kihara noting the country had already participated in earlier reserve draws.

The announced release immediately impacted refining economics. The ICE gasoil crack spread—a key indicator of diesel refining margins—fell to about $70 per barrel from as high as $85 a barrel last week, OilPrice.com reported, citing analysis from ING. While still historically high, the drop reflects expectations for increased diesel supply. For Bakken operators, whose production yields a significant portion of high-value distillates, narrowing crack spreads can signal potential pressure on wellhead realizations for crude streams priced against diesel.

Offsetting some downward price pressure are ongoing supply risks in the Middle East. Attacks on commercial vessels around the Strait of Hormuz have increased, with seven strikes reported since September 28, according to OilPrice.com. This has severely disrupted logistics, sending freight costs for Very Large Crude Carriers (VLCCs) from the Persian Gulf to an all-time high of $1.3 million per day. These costs now add approximately $33 to the price of a barrel shipped from the region, compared to $1.73 per barrel in January.

The soaring transport costs are reshaping global crude pricing. Saudi Aramco's official selling prices for November reflect this, according to OilPrice.com. The state oil giant cut its key Arab Light grade for Asian buyers to a $5 per barrel discount to the Dubai/Oman benchmark, the lowest price in six years, while raising prices for Europe by $3 per barrel. Prices for U.S.-bound cargoes were left unchanged. The deep discount to Asia is a direct response to the surge in shipping costs from the Persian Gulf, as Saudi Arabia employs complex and expensive ship-to-ship transfers to mitigate the risk of Iranian attacks.

For Bakken producers, the mixed global picture presents a complex backdrop. Sustained high Brent prices support a strong global market, while the dip in WTI may reflect near-term U.S. supply expectations from the reserve release. The critical Bakken differential to WTI was not defined in early Monday trading. The focus for local operators will be on whether the G7's diesel release tempers the high refining margins that have benefited the region's crude slate and on monitoring any escalation in Middle East tensions that could further tighten global supply.
