Brent Crude Hits a Five-Month High of $111.05 as Houthi Attack Claims and Gulf Vessel Attacks Fuel Supply Fears

Brent crude hit a five-month high of $111.05 a barrel on Tuesday, powered by Houthi attack claims against Saudi energy targets and a run of reported attacks on vessels in the Gulf that have fuelled fresh supply fears, according to Reuters. By 0810 GMT the global benchmark had eased only slightly, trading at $110.80, up $1.25, or 1.1%, on the day. Across the Atlantic, U.S. West Texas Intermediate rose as high as $104.94 a barrel — its highest since September — and was last at $104.80, up $1.14, or 1.1%, Reuters reported.

There is a particular kind of oil rally that has nothing to do with how much crude the world is burning and everything to do with how much it is worrying, and Tuesday morning delivered exactly that kind. These are not panic numbers, exactly. They are something more stubborn: the price of a market that has decided the risk around the world's most important energy region is not going away anytime soon, and is charging accordingly for every barrel that has to move through it.

Claims Riyadh Has Not Confirmed

The immediate trigger was a set of claims from Yemen's Iran-aligned Houthis. The group said on Monday that it had launched several attacks on Saudi energy, airport and military targets, naming an Aramco site in Yanbu, the Shaybah oilfield, Riyadh's King Khalid International Airport and Abha airport, according to Reuters.

Here is the part that matters, and it is worth stating plainly: Saudi authorities did not immediately confirm those claims, and Reuters said it could not independently verify them. The named targets — an Aramco site on the Red Sea coast at Yanbu, one of the kingdom's great oilfields at Shaybah, and two airports including the capital's international gateway — are exactly the kind of targets whose names alone can move a market, whether or not a single claim behind them has been corroborated. Traders were not waiting for confirmation. By Tuesday morning in London, the premium was already in the price.

That is the uncomfortable logic of energy markets in a crisis. A claim does not have to be proven to cost money. It only has to be plausible enough that nobody wants to be caught short if it turns out to be true.

Eighteen Vessels in Two Weeks

If the Houthi claims supplied the spark, the shipping lanes supplied the fuel. Shiptracker Kpler said in a note on Monday that at least 18 vessels were reportedly attacked over the course of two weeks, a tempo of incidents that, in Kpler's assessment relayed by Reuters, is keeping the risk premium in oil prices intact.

Eighteen vessels is not a statistic traders can shrug off. Every reported attack reprices insurance, reroutes captains, slows transits and reminds the market how much of the world's crude still moves on water within reach of a conflict that keeps widening its aim. Oil has now stayed above $100 a barrel amid the renewed attacks and the fears they have generated for regional supply, Reuters reported — a level that, not long ago, would have dominated front pages on its own. This week it is simply the floor the market is standing on while it watches the Gulf.

The Human Cost Behind the Headline Number

It would be easy to let this story live entirely on a trading screen, and that would be a mistake. The same Monday that brought the claims against Saudi targets also brought word, via Reuters, of a Houthi attack on a training camp for government security forces in Yemen's Shabwa province that killed 58 people and injured more than 200. Behind every dollar added to a barrel this week is a conflict that is killing people in large numbers, in a country that has already endured years of war. The market's risk premium and Yemen's catastrophe are the same story told in two different languages, and only one of them is quoted in dollars.

What the Analysts Are Saying

ING's analysts, in a note on Tuesday reported by Reuters, put the market's mood into words that are hard to argue with: "Oil prices remain well-supported... This suggests the market is pricing in a significant risk premium, given the situation's volatility." The bank's analysts added the conditional that now hangs over the whole trade — if oil flows continue uninhibited, that premium would likely erode slowly — while noting there are no signs of that erosion yet.

Read that again, because it is the whole story in one sentence. The premium is not really about barrels that have stopped moving. It is about barrels the market fears could stop moving. As long as vessels keep getting attacked and claims keep landing against Saudi infrastructure, nobody holding a short position sleeps well, and nobody selling into this market is in a hurry to offer a discount.

There was a quieter, more conventional support under prices as well. In the United States, analysts expected crude and product stockpiles to have fallen last week, according to a preliminary Reuters poll conducted on Monday. Falling inventories do not create a five-month high by themselves, but layered under a geopolitical premium, they remove one of the few arguments the bears had left.

Europe's Markets Felt It Immediately

The spillover into wider markets was visible within hours. In London, the FTSE 100 fell 0.8% to 10,680.25 by 1006 GMT on Tuesday, Reuters reported, with bank shares down nearly 2% to a low of more than four months — HSBC, Lloyds and NatWest fell between 1.6% and 2.3% — while defensive healthcare stocks rose 0.5% and cushioned the index's fall. That is a classic risk-off fingerprint: money running out of the banks that suffer when growth wobbles, and into the drugmakers people buy no matter what the world is doing.

Germany told a similar story with an inflation twist. The DAX was down 218.52 points, or 0.86%, at 25,101.25 by noon, according to RTTNews via dpa-AFX, with Siemens down nearly 4%. And the economic data handed European policymakers a problem of their own: German producer prices rose 6.7% year-on-year in September, the fastest pace since March 2023, up from 4.6% in August. Expensive energy feeding factory-gate inflation, while stock markets slide, is precisely the combination central bankers dread — and precisely why a five-month high in Brent is never just an oil story.

What Happens Next

The honest answer is that Tuesday's price is a question, not a conclusion. If Saudi authorities confirm real damage to energy infrastructure — or if another vessel is hit in the days ahead — the premium ING describes has room to grow. If the claims fade without confirmation and tankers keep moving, the same premium can leak away slowly, exactly as ING's analysts suggested it would. In the United States, meanwhile, traders were already looking past the opening bell: Nasdaq 100 futures slipped on Tuesday as AI-linked stocks weakened and oil rebounded, Reuters reported, with SpaceX and Netflix earnings due after Tuesday's close and Meta and Tesla reporting on Wednesday.

For now, though, the number on the screen is the story. One hundred and eleven dollars and five cents — the most the world has been willing to pay for a barrel of Brent since May, paid not for oil that has been lost, but for oil everyone is suddenly less sure will arrive. In this market, that uncertainty is the most expensive commodity of all.
