Brent crude, the international oil benchmark, was quoted at about $107.96 a barrel on 19 October 2026, down $1.90 or 1.73% from a previous close of about $109.86. On Friday 16 October, Brent touched $110 and settled at $109.86, up 3.7%, its first close at that level since 19 May. These figures are indicative rather than official exchange settlements.

What is driving the market

Brent slipped below $108 on Monday but kept most of the previous week's gains, with hostilities in the Middle East and Eastern Europe keeping supply risks elevated. Three developments stand out.

First, Saudi forces and Iran-backed Houthi rebels continued to clash, and the Houthis targeted Yanbu, a key oil export hub on the Red Sea. Second, three tankers were damaged over the weekend near the Strait of Hormuz, and Iran's naval wing of the Revolutionary Guards said the waterway remained closed except to vessels it authorises. Third, Ukrainian attacks set fires at an oil export terminal and a storage depot in St Petersburg.

A Saudi-led campaign against the Houthis reportedly began in early October, and missile strikes were reported to have hit Saudi airports. Individual casualty and damage claims remain unconfirmed.

Factors pulling the other way

US President Donald Trump said he had reached a diesel export deal with Russia and delayed new sanctions to protect peace talks with Ukraine, which may ease some supply concerns. Members of the International Energy Agency have pledged to release the remaining 100 million barrels from their emergency stockpile, and the US has reportedly offered up to 17 million barrels from its Strategic Petroleum Reserve.

Demand-side signals are mixed. The S&P 500 fell 1.1% on Friday, the US 10-year Treasury yield held at 5.09%, and futures implied only a modest chance of a rate rise at the Federal Reserve's October meeting.

Physical flows add a note of caution about reading too much into prices alone. Some market reports suggest crude cargo volumes through Hormuz were recently near pre-war levels even as attacks on ships escalated, while others indicate that average daily Gulf flows fell sharply in the week to 13 October. These accounts do not obviously agree.

Inventories

Brent is a seaborne benchmark, so US stocks are an indirect guide, but they are the best official data available. US Energy Information Administration figures show commercial crude stocks of 415.6 million barrels in the week ending 9 October, down 8.6 million barrels, with refinery utilisation at 93.5%. US crude exports were 4.57 million barrels a day. Comparable data for European or Asian stocks were not available.

Listed companies with Brent exposure

Producers with Brent-linked output gain from higher prices, while refiners and airlines are buyers. Only producers and integrated groups are covered here, and the picture varies with hedging and gas weighting.

In the United Kingdom, Shell (LSE:SHEL) reported second-quarter earnings of nearly $10 billion, a figure that predates the latest price rise. Shell is an integrated group with large trading, LNG and refining operations, so crude is only one driver of profit.

In the United States, ExxonMobil (NYSE:XOM) was reported to have earned about $14.5 billion and Chevron (NYSE:CVX) about $12 billion in the second quarter. Both have large international upstream positions priced off Brent, as well as US onshore output priced off WTI.

In Australia, Woodside Energy (ASX:WDS) has a gas-heavy mix. Crude and condensate were about 41% of its first-quarter output, most volumes are not directly tied to Brent, and 30 million barrels of oil equivalent of 2026 oil output was hedged at an average of $74.23 a barrel. That hedging means part of the upside from today's price is not captured. Santos (ASX:STO) has historically moved less than Woodside on Brent days, though that ratio is not a measure of commodity leverage.

In Canada, Suncor (TSX:SU) is an integrated oil sands producer whose chief executive said it would not yet speed up planned output increases. Canadian Natural Resources (TSX:CNQ) is a large producer whose second-quarter report sets out its commodity exposure in detail.

What could change the picture

Factors that could support prices include further damage to export infrastructure, continued restrictions at Hormuz, more strikes on Russian energy sites, and renewed inventory draws. Factors that could weaken them include a ceasefire or reopening of shipping lanes, a durable Russian diesel arrangement, further strategic stock releases, and signs that high prices and interest rates are cutting demand. Producers estimate that the supply loss since the conflict began is large and may take many months to rebuild even if the strait reopens. None of this is a forecast.

Contract note and data to watch

The contract month behind the quoted price was not specified. Front-month Brent futures expire at the end of each month, so the quoted continuous price may roll to the next contract as late October approaches; the roll can change the reported price independently of market news.

The next EIA weekly report is due on Wednesday 21 October. Also worth watching are the Federal Reserve's October meeting, shipping notices for Hormuz and the Red Sea, the status of the Russia sanctions delay, and third-quarter results from Shell and the US majors, which should show how much of the higher price reached profits after hedging.
