Oil prices climb above $113 as AI sell-off rattles stocks and investors buy bonds

Brent crude rose because investors feared that fighting involving Iran and attacks in Saudi Arabia could disrupt oil production, transport, and exports. A wider regional conflict could choke global energy supplies, so traders added a risk premium to oil prices.

The immediate move was sharp. Brent jumped 4% on Thursday, settled at $113.17, then traded at $113.73 early Friday. West Texas Intermediate also rose to $100.08. The attacks increased concern that physical supplies might become harder to move from the region.

Shipping made the pressure worse. By mid-October, moving crude from the Middle East Gulf to Asia cost more than $37 per barrel, over five times its prewar level. That expense raises the delivered price of oil, while gas prices also climbed. Higher energy costs can intensify inflation worries and pressure economies.

An AI stock sell-off happens when investors rapidly sell shares of companies connected with artificial intelligence, pushing their prices down. It can reflect doubts about future profits, expensive financing, or valuations that rose too far during a long market boom.

The effect on indexes depends on company size. Nvidia fell 4.4% and was the single biggest drag on the S&P 500 because its market value is larger than any other Wall Street company. Meta lost 7%, Tesla fell 3.1%, and CoreWeave dropped 10.1%. These declines helped push the S&P 500 down 1.2% and the Nasdaq down 2.6%.

The weakness was concentrated in technology. Most other US stocks actually rose, but large AI-related companies pulled the major indexes lower. Microsoft, Amazon, and Alphabet earnings will provide another test next week.

The cost of shipping crude from the Middle East Gulf to Asia climbed above $37 per barrel by mid-October. MarketWatch reported that this was more than five times the cost before the war began. The increase shows how conflict can make transporting energy far more expensive.

Shipping is part of the price buyers ultimately face. When tankers cost more to hire, sellers and buyers must absorb or pass on that extra charge. The article also describes a risk premium caused by attacks and fears of a wider regional conflict. Together, supply worries and transport costs push crude prices higher.

This matters beyond oil traders. Brent traded at $113.73 early Friday, while European gas futures moved above €90 per megawatt-hour. More expensive energy can add to inflation concerns and increase costs for households, companies, and economies.

Oil and natural gas are basic energy inputs, so a sudden price jump can spread through an economy. Households may pay more for heating, electricity, fuel, and goods whose production or transport uses energy. Businesses can also face higher operating costs and may pass them on as higher prices.

The article shows this pressure clearly. Brent traded above $113 a barrel, and Dutch TTF gas futures rose above €90 per megawatt-hour. It says investors were watching whether higher energy prices and borrowing costs would affect growth. Rising bills can squeeze household budgets, while expensive energy can reduce companies’ spending and investment.

The result can be a difficult combination: stronger inflation alongside slower growth. Central banks may remain concerned about price pressures, while consumers and businesses cut back. The article does not quantify household bills or growth effects, but it identifies energy prices as a major economic risk.

AI companies need enormous sums to build data centres and obtain advanced chips. When they fund that expansion with borrowed money, higher interest rates increase their financing costs. Investors may also worry that the new capacity will not generate enough revenue or profit to justify the debt.

CoreWeave illustrates the concern. It borrowed money to buy Nvidia’s AI chips and rent access to them through cloud services. Its shares have been particularly shaky because investors worry about its debt, and the stock dropped 10.1%. The article says similar concerns hit AI-related stocks more broadly.

This vulnerability matters because AI shares had risen during a years-long boom. Even though industry companies continued reporting growth, investors feared prices had climbed too high. Next week’s results from Microsoft, Amazon, and Alphabet, plus the Federal Reserve’s rate decision, could test confidence further.

A government bond yield measures the return an investor receives from holding a government bond, usually relative to the price paid. Bond prices and yields generally move in opposite directions. When demand pushes a bond’s price higher, its yield falls; when investors sell, its price falls and its yield rises.

That relationship appeared on Thursday. Investors were unsettled by the AI-stock sell-off and bought US government bonds as a safer asset. Stronger demand lifted Treasury prices, so the 10-year yield dropped to 4.97% from 5.13% late Wednesday. The daily fall of 16 basis points was unusually large for that benchmark.

The move happened despite evidence that US layoffs remained low. New unemployment-benefit applications fell to 194,000. Investors were balancing economic data against market fear, debt concerns, inflation risks, and the need to protect capital.

These markets form a chain. Higher oil and gas prices can increase inflation, because energy affects household bills, transport, and business costs. If inflation looks persistent, investors may expect interest rates to stay higher. Higher rates make borrowing more expensive and can reduce the value investors place on future company profits, pressuring stocks.

Bonds respond too. Higher expected rates and inflation can make existing bonds less attractive, pushing their prices down and their yields up. The reverse happened Thursday: AI stocks fell, investors sought safety in Treasuries, bond prices rose, and the 10-year yield dropped from 5.13% to 4.97%.

The relationship is not one-way. Stronger economic data can support stocks but also keep rates high. Investors were watching energy prices, debt loads, business surveys, earnings, and the Federal Reserve’s next decision for clues about the direction of markets.
