Brent Crude Holds Above $105 as Gulf Disruption Outweighs Russian Diesel Relief

Brent crude stayed above $105 even after a temporary easing of restrictions on Russian diesel exports. Investors are focusing on Gulf shipping risks, a wide Brent-WTI spread, and the possibility of further supply disruptions.

Brent crude remained above $105 a barrel on October 13, 2026, underscoring how deeply the oil market is pricing Gulf supply risk. The move came despite a temporary policy shift meant to bring more Russian diesel into global markets and ease fuel tightness.

West Texas Intermediate for November delivery traded at $93.68 by 10:24 a.m. ET, while Brent changed hands at $105.70 and Murban at $110.10. Early losses of more than 2% in both main crude benchmarks were reversed as traders refocused on tanker attacks, strained Gulf shipping lanes, and renewed security concerns in Saudi Arabia.

The central market message is clear: an incremental diesel supply boost measured in tens of thousands of barrels a day is not enough to offset disruption risk tied to millions of barrels moving through the Gulf and the Strait of Hormuz.

Key Facts

  • WTI traded at $93.68 a barrel and Brent at $105.70 at 10:24 a.m. ET on October 13, 2026.
  • Brent touched $107.33 on October 12, its highest level in more than two weeks, while WTI reached $94.36 intraday.
  • Russia pledged 300,000 tonnes of diesel in October, equivalent to about 75,000 barrels a day, rising to 250,000 barrels a day by year-end 2026.
  • The Brent-WTI spread widened to $12.02 a barrel, reflecting a premium on seaborne crude exposed to Middle East shipping risk.
  • Gulf refined-product exports were running at about 60% of prewar levels, while crude and condensate shipments recovered to about 91%.

Brent Crude

Brent crude is acting as the clearest barometer of geopolitical risk in energy markets. A temporary lift to restrictions on Russian diesel exports initially pushed prices lower, but the reaction faded quickly. Traders judged that the additional diesel volumes, while directionally helpful for fuel markets, do little to resolve the broader problem: crude and products moving through contested shipping routes remain vulnerable.

The supply arithmetic explains why Brent crude has held firm. Russian diesel shipments are set to start at roughly 75,000 barrels a day in October and rise over subsequent months. By comparison, disruptions linked to the Gulf and Hormuz have affected export flows on a much larger scale. Reduced tanker traffic, rerouting, higher insurance costs, and the threat of attacks on infrastructure have all tightened the market for internationally traded barrels.

Who is affected depends on location within the energy chain. U.S. inland crude is relatively insulated, which helps explain why WTI has lagged Brent. Refiners and import-dependent economies face the sharpest stress because diesel and other refined products remain especially tight. Shipping companies, tanker operators, and non-Gulf oil exporters stand to benefit as buyers search for alternative routes and substitute barrels.

The oil market is signaling that refined-product relief cannot solve a crude supply problem rooted in Gulf security risk.

Why the Brent-WTI spread matters

The $12.02 gap between Brent and WTI is one of the most important signals for investors. It shows that global buyers are willing to pay a steep premium for barrels priced into seaborne benchmarks, even as those same barrels carry elevated transport and disruption risk. In normal conditions, that spread is much narrower.

This dislocation can create secondary effects. Higher export incentives may pull more U.S. crude into overseas markets, eventually tightening domestic balances and supporting WTI. At the same time, elevated Brent pricing feeds directly into the economics of refining, tanker freight rates, and inflation expectations across importing regions.

Implications for Investors

For investors, the first takeaway is that energy price risk remains heavily geopolitical rather than purely fundamental. Brent crude has risen 70% over the past 12 months, while WTI is up 59% year over year. That divergence, combined with the wide inter-benchmark spread, suggests portfolios with exposure to global energy trade may continue to outperform if Gulf tensions persist.

The second takeaway is that not all energy exposures are equal. Tanker operators and exporters outside the Gulf may remain leveraged to route dislocation and longer voyage times. U.S. refiners can also benefit when discounted domestic crude meets elevated refined-product pricing. By contrast, sectors sensitive to inflation, transport costs, or consumer fuel demand may face renewed margin pressure if oil and diesel remain elevated into the fourth quarter.

Investors should also watch policy risk closely. Temporary sanction relief for Russian diesel, possible strategic stockpile releases, and any additional measures aimed at lowering fuel prices ahead of the November 3 midterm elections could create short-term volatility. Yet a durable pullback in Brent crude likely requires a credible de-escalation in Gulf security conditions, not just incremental supply adjustments elsewhere.

Looking ahead, the market will be watching whether Brent crude can decisively break above $107.33 and test $110. A sustained easing in Hormuz traffic risk would change that outlook, but until then the geopolitical premium in oil prices appears firmly intact.
