NEW YORK (AP) mdash; Oil shot to its highest price since 2023 after surging again Friday because of the Iran war, and a weak update on the U.S. job market knocked stocks lower to cap Wall Streetrsquo;s worst week since October.The SP 500 dropped 1.3% after a report showed U.S. employers cut more jo bs last month than they created and after oil prices spiked above $90 per barrel. The combination of a weak economy and high inflation is a worst-case scenario for investors because the Federal Reserve has no good tool to fix both problems at the same time.The Dow Jones Industrial Average plunged as many as 945 points before finishing with a loss of 453, or 0.9%, and the Nasdaq composite sank 1.6%.ldquo;You canrsquo;t sugarcoat this report,rdquo; according to Brian Jacobsen, chief economic strategist at Annex Wealth Management. ldquo;A negative payrolls number combined with a big jump in oil prices will have traders worrying about stagflation risks.rdquo;Stagflation is what economists call the miserable mix of a stagnating economy with high inflation, and a separate report released Friday added to the sourness after showing that U.S. retailers made less money in January than economists expected. It raised the disconcerting possibility that spending by U.S. households, the main engine of the economy, may be stretched near its maximum.Usually when the economy is unsteady and the job market is weakening, the Federal Reserve cuts interest rates to give things a boost. Lower rates can make it easier for households to get mortgages and for companies to raise money to expand, while also lifting prices for stocks and other investments. The Fed cut its main interest rate several times last year and had indicated more were to come this year.But lower interest rates can also make inflation worse. And the Fedrsquo;s hands may be increasingly tied because spiking oil prices are pushing inflation higher due to disruptions for the energy industry.The price for a barrel of Brent crude, the international standard, leaped another 8.5% to settle at $92.69. It briefly rose above $94 to touch its highest level since September 2023.A barrel of benchmark U.S. crude breached the $90 level for the first time since 2023 and jumped 12.2% to $90.90.Oil prices have surged, with Brent up from near $70 late last week, as the war has expanded and included areas critical to the production and movement of oil and gas in the Middle East. Much will depend on what happens with the Strait of Hormuz off Iranrsquo;s coast, where roughly a fifth of the worldrsquo;s oil typically sails.The U.S. government gave details Friday about a plan President Donald Trump announced earlier to offer insurance to ships crossing the strait, but it had little effect on the market.If oil prices spike further, like to $100 per barrel, and stay there, some analysts and investors say it could be too much for the global economy to withstand.To be sure, the U.S. stock market has a history of bouncing back relatively quickly following conflicts in the Middle East and elsewhere, as long as oil prices donrsquo;t jump too high for too long. Uncertainty about just how high oil prices will go this time around and for how long caused frenetic swings across financial markets this past week, sometimes hour by hour.On Monday, the SP 500 tumbled to an immediate 1.2% loss at the start of trading but made it all back and ended the day with a tiny gain.Trumprsquo;s most recent signal on the war was that he wants an ldquo;unconditional surrenderrdquo; of Iran, apparently ruling out negotiations.In the bond market, Treasury yields wavered, with higher oil prices pushing upward on them and the discouraging updates on the U.S. economy pulling downward.The yield on the 10-year Treasury initially rose toward 4.19% before pulling back to 4.14%. Thatrsquo;s up from 4.13% late Thursday and just 3.97% a week earlier.Smaller companies often feel the bite of high borrowing costs more because many need to borrow to grow. Smaller companies can also be more dependent on the strength of the U.S. economy for their profits than big multinational rivals, and the smallest stocks on Wall Street took Fridayrsquo;s sharpest dives.The Russell 2000 index of small stocks fell a market-leading 2.3%.Among the big companies in the SP 500, companies with high fuel bills helped lead the way lower. Old Dominion Freight Line sank 7.9%, cruise line Carnival fell 5% and Southwest Airlines lost 5.3%.All told, the SP 500 fell 90.69 points to 6,740.02. The Dow Jones Industrial Average dropped 453.19 to 47,501.55, and the Nasdaq composite sank 361.31 to 22,387.68.In stock markets abroad, indexes slumped in Europe following a better finish in Asia. London's FTSE 100 fell 1.2%, while Hong Kongrsquo;s Hang Seng jumped 1.7%.South Korearsquo;s Kospi was nearly unchanged after plunging 12.1% Wednesday for its worst loss in history and then rebounding 9.6% Thursday.Permalink| Comments ...read more read less
