US stocks erase sharp losses, while oil prices leap on worries about
Iran war

NEW YORK (AP) — Oil prices leaped Monday on worries that war with Iran
could clog the global flow of crude and make inflation even worse. U.S.
stocks, meanwhile, swung from sharp losses to a tiny gain.
Crude prices jumped more than 6%, which will likely mean higher prices
soon at gasoline pumps. That would hurt not only U.S. households, whose
spending makes up the bulk of the U.S. economy, but also businesses with
big fuel bills.
The S&P 500 fell as much as 1.2% at the start of trading, and cruise
lines and airlines led the way lower. But U.S. stocks quickly erased
those losses, in part because past military conflicts haven’t usually
created sustained drops for the market, and the index finished the day
with a gain of less than 0.1%.
The Dow Jones Industrial Average dipped 73 points, or 0.1%, and the
Nasdaq composite rose 0.4%. Both also came back from steep early losses.
Prices for natural gas remained higher, meanwhile, which could raise
heating bills for the remainder of the winter, after a major supplier of
liquefied natural gas to Europe said it would stop production because of
the war. Gold climbed 1.2% as investors looked for safer things to own
and as U.S. officials tried to persuade the world that this war will not
last forever.
“This is not Iraq,” U.S. Defense Secretary Pete Hegseth said Monday.
“This is not endless.”
Typically, Treasury yields also fall in the bond market when investors
are feeling nervous. But yields instead climbed, in part because higher
oil prices will put upward pressure on inflation, which is already worse
than nearly everyone would like. That could tie the Federal Reserve’s
hands and keep it from cutting interest rates.
Lower interest rates can boost the economy and job market, but they also
worsen inflation. Higher rates can do the opposite.
Past military conflicts in the Middle East have not caused long-term
drops for markets. For this war to knock down U.S. stocks in a
significant and sustained way, the price of oil would perhaps need to
jump above $100 per barrel, according to strategists at Morgan Stanley
led by Michael Wilson.
Oil prices are still well below that level, even with Monday’s jump. The
price for a barrel of benchmark U.S. crude rose 6.3% to settle at
$71.23. Brent crude, the international standard, climbed 6.7% to $77.74
per barrel.
That helped the U.S. stock market pare some of its steep, opening loss.
Morgan Stanley also said the S&P 500 has climbed an average of 2%, 6%
and 8% in the one, six and 12 months following “geopolitical risk
events” historically. That’s going back to the Korean War, which began
in 1950, and the 1956 Suez crisis.
At this moment, though, fear is still running through markets.
Stocks of airlines were some of Monday’s sharpest losers. Not only do
higher oil prices threaten their already big fuel bills, the fighting in
the Middle East also closed airports and left travelers stranded.

 American Airlines lost 4.2%, United
Airlines fell 2.9% and Delta Air Lines sank 2.2%.
Norwegian Cruise Line Holdings dropped even more, 10.6%. It needs
customers to have plenty of cash to spend after paying for gasoline
and other essentials.
The cruise operator also reported weaker revenue for its latest
quarter than analysts expected, though its profit was better. Its
forecast for profit this upcoming fiscal year was also lower than
analysts expected.
Stocks in the housing industry struggled as higher Treasury yields
could translate into more expensive mortgage rates. Homebuilder D.R.
Horton lost 3.7%, and Builder FirstSource sank 4.7%.
Helping the U.S. stock market to bounce back from its early losses
were oil companies, which benefited from the rising price of crude.
Exxon Mobil climbed 1.1%, and Marathon Petroleum rose 5.9%.
Companies that make equipment for the military also strengthened.
Northrop Grumman climbed 5.9%, and RTX rallied 4.7%.
Palantir Technologies, whose software helps global defense agencies
and other customers, jumped 5.8% for one of the biggest gains in the
S&P 500.
Big Tech stocks also helped support the market. Nvidia rose 2.9% and
was the strongest single force pushing the S&P 500 higher.
All told, the S&P 500 added 2.74 points to 6,881.62. The Dow Jones
Industrial Average dipped 73.14 to 48,904.78, and the Nasdaq
composite rose 80.65 to 22,748.86.
In stock markets abroad, indexes sank across much of Europe and
Asia. Germany’s DAX lost 2.6%, France’s CAC 40 fell 2.2% and Hong
Kong’s Hang Seng dropped 2.1% for some of the world’s larger losses.
Stocks in Shanghai were an outlier and rose 0.5%.
In the bond market, the yield on the 10-year Treasury rose to 4.04%
from 3.97% late Friday. A report showing growth for U.S.
manufacturing was better last month than economists expected also
helped to lift yields.
