Kuwait's government said an Iranian strike had knocked generating units offline at a combined power and desalination plant; Brent settled $88.10 that Friday and took the $90 handle by Monday.

Key takeaway

Brent cleared $90 with freight and insurance confirming the move for the first time in this conflict.

Brent Crude settled $88.10 on Friday 17 July, up 4.6% on the day, after Kuwait's government said an Iranian strike had damaged a combined power-generation and water-desalination plant and taken a large number of generating units offline 1. By Monday 20 July, with US forces completing a ninth consecutive night of strikes on Iranian targets, September Brent traded above $90 and August West Texas Intermediate at $84.38 2.

Brent is the seaborne benchmark against which most crude landing in European refineries is priced; WTI settles into a landlocked tank farm at Cushing, Oklahoma. The gap between the two is the market's running estimate of what it costs to get a waterborne barrel out of a war zone, which is why the spread is worth more attention this week than either outright.

That spread widened to $5.61 on 17 July from $5.13 two days earlier , then held near $5.62 through Monday. Three sessions of escalation, and it stopped blowing out. The bid is being priced as a seaborne-delivery problem with a ceiling on it rather than an open-ended one. Cushing is inland; Strait of Hormuz cargoes are not, and the market has now put a number on that difference and left it there.

The Baltic Exchange freight assessment and London war-risk hull rates both repriced inside this same window, having sat out every flat-price move for the previous six weeks. Brent rose to $79.16 on a fourth US strike with tanker freight flatly refusing to confirm it . A flat-price rally that freight ignores retraces on the next communique. A rally that freight and war-risk underwriters have signed off on is embedded in landed cost until the loss record changes.

Deep Analysis

In plain English

Brent and WTI are the two main prices used to buy and sell oil around the world. Brent tracks oil that travels by sea, so it gets more expensive when ships face danger, like near the Strait of Hormuz between Iran and the Gulf states. WTI moves through pipelines in the US and does not face that risk. When Iran hit a Kuwaiti power plant on 17 July and the US kept bombing Iranian targets for a ninth straight night, sea-based Brent jumped further than land-based WTI, widening the gap between the two prices.

Deep Analysis
Root Causes

The spread's ceiling behaviour traces to a structural asymmetry, not sentiment: WTI delivers landlocked at Cushing, Oklahoma, so it carries no Strait of Hormuz exposure, while Brent prices cargo that must physically transit the 33km chokepoint.

The CFTC's Tuesday-cutoff, Friday-release cycle means the 17 July print already excluded the Kuwait strike that happened that same day, so the professional book the market is reading was stale before it was published.

What could happen next?
  • Consequence

    A Brent-WTI spread stabilising near $5.61-5.62 signals traders are pricing Hormuz risk as bounded rather than open-ended, which caps how far European fuel costs rise from this specific escalation.

  • Risk

    A further Hormuz casualty could push the spread past its current ceiling if underwriters treat it as evidence the risk band has shifted rather than plateaued.

Different Perspectives
Shipping and insurance industry
Shipping and insurance industry
UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.
European refiners
European refiners
European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.
Saudi Arabia
Saudi Arabia
Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.
Qatar
Qatar
Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.
Iran (foreign ministry and Majlis)
Iran (foreign ministry and Majlis)
Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.
Russia and China
Russia and China
Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
