Japan ruling party elects new leader; yen weakens

By Caroline Valetkevitch

NEW YORK, Oct 6 (Reuters) - Major stock indexes climbed

on Monday, with technology shares rising on news of AMD's

artificial intelligence chip-supply deal with OpenAI,

while the yen and euro weakened against the dollar after Japan's

ruling party elected a new leader and France's new government

quit.

Bitcoin hit a record high as investors increasingly sought

alternative assets and uncertainty prevailed with the U.S.

government shutdown. The world's largest cryptocurrency

was last up 2.16% at $125,426.34.

The euro was down 0.2% at $1.1717. New French Prime

Minister Sebastien Lecornu resigned on Monday, barely 14 hours

after appointing his cabinet.

Japan's ruling party picked conservative Sanae Takaichi, putting

her on course to become the nation's first female prime

minister. She is an advocate of late premier Shinzo Abe's

"Abenomics" strategy to boost the economy with aggressive

spending and easy monetary policy.

On Wall Street, the S&P 500 and Nasdaq rose while the Dow was

slightly lower, as the U.S. federal government shutdown, which

began last week, dragged on. The S&P 500 finished last week at a

record closing high.

"The market is extending its momentum bias. It's shrugging

off the (U.S.) government shutdown and, because of that, there's

a belief that perhaps the Fed is going to be more generous than

the market previously expected," said Peter Cardillo, chief

market economist at Spartan Capital Securities in New York.

The Federal Reserve is widely expected to cut interest rates

again by 25 basis points at its October 28-29 meeting, following

data that shows a weakening labor market.

Moreover, Cardillo said, "we're not far away from

third-quarter earnings, and it looks as though it'll be another

good earnings season." Earnings season for S&P 500 companies

unofficially kicks off next week with reports from some big U.S.

banks.

AMD shares jumped more than 25% and other chip companies'

stocks also rose amid optimism around AI deals. The S&P 500

technology index was up 0.8%.

The Dow Jones Industrial Average fell 57.83 points,

or 0.12%, to 46,700.45. The S&P 500 rose 29.67 points, or

0.44%, to 6,745.46 and the Nasdaq Composite advanced

194.13 points, or 0.85%, to 22,974.63.

MSCI's gauge of stocks across the globe

rose 3.14 points, or 0.32%, to 996.35. The pan-European STOXX

600 index fell 0.04%.

French political instability has ramped up since Emmanuel

Macron's re-election in 2022, with no party or grouping holding

a parliamentary majority.

In Japan, the Nikkei soared above 48,000 for the first

time after Takaichi beat the more moderate Shinjiro Koizumi in

the Liberal Democratic Party's leadership vote.

Short-dated Japanese government bond yields slid to a

two-week low as traders pared bets on when the

Bank of Japan will resume raising interest rates.

"There's a little bit more focus on the back end of the

curve now, just given that Takaichi is generally seen as a

follower of Abenomics. The market expects a little bit more

fiscal stimulus there," said Sarah Ying, head of FX strategy,

FICC Strategy at CIBC Capital Markets in Toronto.

Most other major share markets around the region were closed

for holidays, including mainland China, South Korea and Taiwan.

Gold surged to an all-time high above $3,900 per ounce, helped

in part by the economic and political uncertainty in the U.S.,

France and Japan. Spot gold rose 1.83% to $3,956.94 an

ounce.

Oil

prices also rose

after OPEC+'s planned production increase for November was

more modest than expected. U.S. crude gained 81 cents to

settle at $61.69 a barrel, while Brent climbed 94 cents

to settle at $65.47.
