Context: Reuters reported on 13 November 2026 that oil prices were set for a second weekly decline because the US plans to continue its blockade of Iranian oil shipments and sanctions, which Reuters said reduced the chance of renewed large-scale fighting, though attacks on shipping remain a danger.

Crude's second weekly fall, in money terms

Reuters reported on 13 November 2026 that Brent futures were little changed, down 1 cent at $95.41 a barrel at 0242 GMT, while West Texas Intermediate fell 20 cents to $88.52. A Reuters-based summary published the same day said Brent was on course to fall 2.4% on the week after a 16% drop the week before, and WTI was set to fall 2.5% after a 13% drop. These are early-Friday figures, not weekly closing prices. (Rallies.ai (summarising Reuters), 13 November 2026)

Reuters reported on 12 November 2026, citing the US Energy Information Administration (EIA), that commercial crude inventories rose by 4.7 million barrels to 414.4 million barrels in the week ended 6 November. Analysts in a Reuters poll had expected a 1.1 million-barrel draw. In its 13 November report Reuters added that the EIA attributed the rise in crude and fuel stocks to softer refined-products demand and a jump in oil imports, and that this put further pressure on prices.

For importers, refiners and airlines in Europe and Asia, the cheaper crude is measured against a higher base. Fortune reported on 12 November 2026 that Brent was at $94.58 a barrel at 6:30am Eastern Time, $1.14 below the previous morning and about $31.50 above its price a year earlier. Trading Economics showed Brent at 96 USD a barrel on 12 November, up 3.49% from the previous day, which shows how far the benchmark can move within one session. Macrotrends, using EIA daily data, put Brent at $107.03 on 3 November 2026, with a 2026 average so far of $96.46 against $69.14 for 2025.

Gulf producers, sovereign funds and listed equities

Gulf equity prices have moved with the security headlines. Business Recorder, carrying Reuters, reported on 14 October 2026 that Saudi Arabia's benchmark index fell 1.7% and Aramco shares fell 1.6% in a session its headline linked to an attack on Aramco. The same report said Saudi National Bank and Al Rajhi Bank each fell 2%. On 11 November 2026, Business Recorder, again carrying Reuters, reported that the Saudi index closed 1.4% higher and Aramco rose 1.6%. Dubai's index gained 0.8%, with Emirates NBD up 4.3%. Abu Dhabi's index edged up 0.3%, while Qatar's index fell 0.5%. (Reuters (carried by Business Recorder), 14 October 2026; Reuters (carried by Business Recorder), 11 November 2026)

The 11 November Reuters report quoted Ranim Turfa, head of research and market analysis for the Middle East and North Africa at Tickmill. She said markets were weighing security risks and watching mediation efforts, and that concerns about renewed escalation persisted. Reuters also reported on 13 November 2026 that risks to oil shipments out of the Strait of Hormuz remain, even as prices ease. For Gulf producers and sovereign funds, oil revenue therefore follows both the Brent price and shipping headlines. TPC found no ministry or IMF revenue estimate published today that quantifies the sensitivity.

Shipowners and marine insurers

The latest war-risk figures TPC could verify are from October and earlier, not live quotes. The Boston Report, citing Insurance Business, reported on 18 October 2026 that Hormuz war-risk premiums had risen from about 0.25% of a ship's value before the conflict to 6% to 10% in October. The National reported on 17 July 2026 that rates then ranged from 3% to 10% of hull value, meaning a $100 million tanker faced a premium of $3 million to $10 million. (The Boston Report (citing Insurance Business), 18 October 2026; The National, 17 July 2026)

Breakwave Advisors said in its bi-weekly tanker report of 3 November 2026 that very large crude carrier (VLCC) rates remained strong on low vessel availability and geopolitics. It said October flows through Hormuz averaged approximately 11.7 million barrels a day, and that the recovery in Middle Eastern crude exports had yet to restore normal tanker circulation. Lower crude prices have not, in the published data TPC found, translated into lower freight or cover costs. (Breakwave Advisors, 3 November 2026)

What to watch next

The first marker is the next tanker incident. Reuters said on 13 November 2026 that attacks on shipping remain a danger. Chris Brankin, global advisor for Melbourne-based brokerage MiTrade, quoted in the same report described the oil market as "priced to perfection at this point", adding that prices had bounced back without much conviction from traders. Equity holders in energy companies and Gulf banks are exposed to the same single-waterway risk, because the 11 November Gulf rally followed an earlier fall of similar size in Aramco shares. (Reuters (carried by 102.7 WBOW), 13 November 2026; Reuters (carried by Business Recorder), 11 November 2026)

The second is the next weekly EIA inventory report, after the 12 November release showed a 4.7 million-barrel crude build against an expected draw of 1.1 million barrels. Reuters said on 12 November that fuel stocks also rose, so the next figures will show whether that build continues. (Reuters (carried by BOE Report), 12 November 2026)

The third is any revival of the Qatari reopening plan. House of Saud, a news site, reported on 6 November 2026 that Qatar had proposed a two-stage, 48-hour plan. It said the first stage covered a lifting of the US blockade and IAEA inspections, and the second a reopening of Hormuz to international navigation. TPC could not confirm the plan's terms in a wire report or official publication, so this describes a proposal as reported by one outlet, not a settled arrangement. Reuters said on 13 November that the US intends to keep its blockade and sanctions in place. (House of Saud, 6 November 2026; Reuters (carried by Business Recorder), 13 November 2026)
