Updates with close of European markets

By Chuck Mikolajczak

NEW YORK, Oct 30 (Reuters) - Global shares retreated on Thursday and were poised for their biggest daily decline in three weeks, bogged down by megacaps Microsoft and Meta Platforms, while the dollar rose against the yen on policy news from the Federal Reserve and Bank of Japan.

Markets were digesting comments from Fed Chair Jerome Powell, who dampened expectations that the U.S. central bank will cut interest rates at its December meeting after easing by 25 basis points on Wednesday.

Market reaction was muted after U.S. President Donald Trump said he had struck a deal with President Xi Jinping to trim tariffs on China in exchange for Beijing cracking down on the illicit fentanyl trade, resuming U.S. soybean purchases and keeping rare earths exports flowing, which markets had been anticipating in recent days.

On Wall Street, the S&P 500 was lower, as Meta Platforms META.O, one of the "Magnificent Seven" group of megacap stocks, plunged nearly 11% after reporting quarterly results and forecast larger capital costs after the close on Wednesday. Bloomberg reported on Thursday that the Facebook and Instagram parent was targeting at least $25 billion in a bond sale.

Also weighing on equities was a 3.2% decline in Microsoft following its quarterly earnings.

Those declines were offset somewhat by a 3.1% climb in Google parent Alphabet GOOGL.O as its earnings beat expectations due in part to strong artificial intelligence demand.

"If the market is being a little bit more discerning, company by company based on their actual results as opposed to these MAG7 or AI-related stocks moving all in sync, that could be deemed somewhat of a positive," said Ron Albahary, chief investment officer at LNW in Philadelphia.

"Investors are starting to at least be more sensitized to, all right, where is the line of sight to return on investment? And the Meta reaction, despite the beat, could be an early sign that narrative is going to be challenged."

Fellow heavyweights Apple AAPL.O and Amazon AMZN.O are scheduled to report earnings after the U.S. market close on Thursday.

Markets are pricing in a 72.8% chance of a 25 basis point cut at the Fed's December meeting, down from more than 90% a week ago, according to CME's FedWatch Tool.

The Dow Jones Industrial Average .DJI rose 141.30 points, or 0.30%, to 47,773.30, the S&P 500 .SPX fell 27.02 points, or 0.39%, to 6,863.39 and the Nasdaq Composite .IXIC dropped 213.42 points, or 0.89%, to 23,745.05.

MSCI's gauge of stocks across the globe .MIWD00000PUS lost 5.10 points, or 0.50%, to 1,009.32 and was on track for its largest daily percentage drop since October 10, while the pan-European STOXX 600 .STOXX index closed down 0.1%.

The European Central Bank (ECB) kept interest rates unchanged at 2% for the third meeting in a row and offered no hints about future moves as it enjoys a rare period of low inflation and steady growth, despite trade turbulence.

In currencies, the dollar index =USD, which measures the greenback against a basket of currencies, advanced 0.39% to 99.52, with the euro EUR= down 0.34% at $1.1566. Sterling GBP= weakened 0.31% to $1.3154.

The dollar strengthened 0.92% to 154.11 yen JPY= after the Bank of Japan (BOJ) kept interest rates steady. Investors had expected a more hawkish tone from Governor Kazuo Ueda, even as he sent the strongest signal yet that a rate hike was possible as soon as December.

The yield on benchmark U.S. 10-year notes US10YT=RR rose 3.5 basis points (bps) to 4.093% after jumping 7.5 bps on Wednesday following Powell's comments, its biggest daily climb since July 11.

The 2-year note US2YT=RR yield, which typically moves in step with rate expectations for the Fed, advanced 2.4 basis points to 3.61% after a 9.2 bp increase on Wednesday, its biggest since July 3.

U.S. crude CLc1 rose 0.26% to $60.64 a barrel and Brent LCOc1 advanced to $65.03 per barrel, up 0.17% on the day as investors gauged the U.S.-China trade deal.
