Oil jumps 3.6% after blasts in the Saudi capital. Nasdaq falls 1.25%, but bonds rally and the 10-year yield eases to 5.231%
Reports of explosions in Riyadh on Thursday, and a Houthi claim of a new attack on the city's airport, sent crude sharply higher. AP quoted a witness describing an evacuation at the airport; Reuters reported that Lufthansa and Indian airlines had suspended flights to the Saudi capital. Saudi officials have disputed Houthi claims before, and we could not independently confirm the damage. WTI settled up about 3.6% near $91.5; NBC said Brent hit $105 at its high. Stocks fell: the S&P 500 lost 0.47% to 7,765.36, the Nasdaq 1.25% to 27,193.34, while the Dow gained 0.10% to 51,231.64. The 10-year Treasury yield closed at 5.231%, down 4.6 basis points, after a 30-year auction that Reuters said found solid demand. Gold rose about 0.2% to roughly $4,157.
Oil is now the swing factor for inflation, and inflation is the swing factor for the Fed. The 10-year yield sets mortgage and corporate borrowing costs, and it touched 5.35% on Wednesday, its highest since 2002. A day when oil jumps but yields fall tells you the bond market is, for the moment, more worried about growth than about prices. That balance can flip quickly.
Gasoline follows crude with a lag of a week or two, and Hurricane Isaias threatens Gulf production too. If you carry a variable-rate loan or are shopping for a mortgage, a lower 10-year yield helps a little; a sustained oil spike would take it back. Retirement accounts tied to the Nasdaq had the worst of Thursday.
The sell-off is a sensible response to a real supply threat. A 3.6% jump in crude, with Hormuz already contested, belongs in stock prices, and technology shares carry the highest valuations.
One day of blasts, partly unverified, should not reset a market. The auction showed buyers at these yields, the president says no strike is coming before the midterms, and the Dow rose.
Watch two lines on Friday. If WTI holds above $90, expect the inflation argument to return before the Oct. 14 CPI report. If the 10-year stays under 5.3%, equities get room to recover. Treat the Riyadh details as unconfirmed until Saudi officials or a second wire service describes the damage, and treat the $105 Brent figure as a peak, not a settlement.
