Dow slides 653 points as oil surge weighs on Wall Street; S&P logs second straight weekly loss

Wall Street closed lower on Friday, October 23, 2026, as the strongest crude market in six months overwhelmed a partial recovery in technology shares, with the Dow Jones Industrial Average shedding 652.82 points, or 1.23 per cent, to settle at 52,215.16, its worst session since August. The sell-off followed Thursday's rout in artificial-intelligence-linked stocks and left major indexes with a mixed weekly record.

The S&P 500 lost 39.75 points, or 0.52 per cent, to end at 7,623.68, and the Nasdaq Composite eased 53.52 points, or 0.21 per cent, to 25,955.34. For the week, the S&P fell 0.5 per cent, its second straight weekly decline, and the Nasdaq dropped 0.7 per cent, while the Dow managed a 0.4 per cent gain, its third consecutive positive week. Nearly three of every four stocks in the broad index ended Friday lower.

Oil set the tone, tech only steadied

The day's moves tracked crude almost tick for tick. Brent crude futures settled at $116.72 a barrel, up 3.1 per cent, and West Texas Intermediate closed at $103.27, lifting the S&P 500's energy sector 2.5 per cent to a record high, according to Reuters, even as every other cyclical group weakened. The gains followed Houthi attacks on Saudi energy infrastructure and mounting expectations that the United States may resume strikes on Iran after the midterm elections.

Technology's partial recovery was the second storyline. A semiconductor index rose 0.4 per cent after its biggest daily drop since June on Thursday, when a report involving Meta Platforms reignited concern about the durability of the artificial-intelligence investment cycle. Micron Technology added 2.5 per cent, Intel 1.7 per cent, Microsoft 0.7 per cent and Advanced Micro Devices 1.7 per cent, but the group could not offset falls elsewhere in the market.

Corporate news that moved the tape

American Express fell 3.7 per cent after reporting quarterly profit above forecasts and simultaneously announcing its first major job reduction in roughly a decade, about 5 per cent of its global workforce, with the chief executive telling investors the company needed to become a more agile organisation in preparation for artificial intelligence, according to CNBC. Goldman Sachs and JPMorgan Chase lost more than 1 per cent each, weighting the Dow.

Telecom shares were a second pressure point after market reports said SpaceX was in discussions with cellular infrastructure companies about launching a United States wireless carrier programme, a potential disruption to incumbent capital spending plans. In earnings, Western Digital beat expectations with fiscal first-quarter adjusted earnings of $4.64 a share on $4.38 billion of revenue, yet the stock still fell 5 per cent as investors continued to de-rate the hardware supply chain attached to data-centre growth.

Rates pressured the equity outlook

Treasury yields re-tightened on Friday. The 10-year yield rose 3.7 basis points to 4.99 per cent, according to Reuters, close to the 5 per cent line it had briefly broken below the previous session in its biggest one-day drop in nearly four years. Thursday's drop reflected a bid for safety amid doubts about the sustainability of borrowing to finance artificial-intelligence data centres, and Friday's rebound in yields kept the pull-and-tug on equity valuations alive.

The bond backdrop also frames next week's Federal Reserve meeting on October 27 and 28, which sits alongside a dense earnings calendar. About one-third of S&P 500 companies report quarterly results over the coming sessions, including the three hyperscalers whose capital spending plans are the market's chief yardstick for return-on-investment conviction in the AI build-out.

Nigerian and emerging-market reading

Two implications deserve Nigerian investor attention. First, a hawkish-leaning Fed decision on Wednesday would lift dollar funding costs and pressure emerging-market assets at exactly the moment Nigeria's own rates are being reset lower, which could test the yield advantage that has drawn foreign portfolio money into Nigerian fixed income. Second, the equity rotation away from technology and into energy mirrors the global real asset bias that benefits oil producers, including Nigerian names tied to crude receipts and fuel distribution.

Volatility is likely to persist. The index level itself matters less than the pair of risks that are driving it: whether the oil escalation premium holds and whether corporate America's capital spending on artificial intelligence keeps justifying current valuations. Both will become clearer, rather than less certain, in the week ahead.
