This is CNBC's live blog covering Asia-Pacific markets.

Asia-Pacific markets mostly fell on Monday as investors assessed business activity figures from several key economies in the region.

China's Caixin services purchasing managers' index from S&P Global rose to 52.2 in December — the service sector's fastest expansion since May 2024. China's central bank said over the weekend it would implement a "moderately loose" monetary policy in 2025 as it seeks to boost growth.

Separately, Hong Kong's PMI declined in December compared to the month before.

India's service PMI expanded at its fastest pace in four months, with final figures for December coming in at 59.3 compared to 58.4 in November. PMI, however, missed the 60.5 reading expected by analysts polled by Reuters.

Hong Kong's Hang Seng index fell 0.48% as of its final hour, while mainland China's CSI 300 dropped 0.16% to 3,769. The CSI 300 marked its fourth straight day of losses and hit its lowest level since Sep. 27, 2024.

Japan's benchmark Nikkei 225 shed 1.47% to end at 39,307.05, leading losses in Asia and dragged by consumer cyclical stocks, while the broad-based Topix fell 1.02% to 2,756.38.

On the other hand, South Korea's Kospi was up 1.91% to 2,488.64, while the small-cap Kosdaq was 1.73% higher at 717.96 and hit its highest level since Nov. 11.

Political uncertainty continues to grip the country, with the country's head of presidential security service reportedly saying over the weekend he could not comply with efforts to arrest impeached president Yoon Suk Yeol.

A bid to arrest Yoon on grounds of insurrection last Friday failed after investigators were locked in a stand-off with presidential security officials.

Australia's S&P/ASX 200 pared gains to trade just above the flatline, ending at 8,257.4

On Friday in the U.S., the Nasdaq Composite and S&P 500 ended their five-day losing streak as tech stocks rallied.

The broad-based S&P 500 closed 1.26% higher, while the Nasdaq Composite gained 1.77% to close at 19,621.68. The Dow Jones Industrial Average advanced 0.8%.

India service sector expands at fastest pace in four months

India's services PMI expanded at its fastest pace in four months, with final figures for December coming in at 59.3 compared to the 58.4 in November.

The reading was lower than the initial 60.8 in the December flash reading about two weeks ago. The final reading also missed the 60.5 expected from analysts polled by Reuters.

"Strength in the services PMI stands in contrast with the growing signs of a slowdown in the manufacturing industry," HSBC economist Ines Lam wrote in the release.

"Forward-looking indicators such as new business and future activity suggested that the strong performance will likely continue in the near future," she added.

China's services sector growth hits 7-month high in December: Caixin survey

China's services sector expanded at its fastest pace in seven months, according to the Caixin survey, compiled by S&P Global.

Its services purchasing managers' index came in at 52.2 in December, up from 51.5 in November.

Caixin said that the acceleration in business activity growth was supported by greater new business inflows, though it noted that export business declined for the first time since August 2023.

Quicker new business growth, however, increased work backlogs, as firms have lowered employment levels due to a decline in business optimism.

Hong Kong business activity expands at slower pace in December

Hong Kong's business activity expanded at a slower pace in December, with the city's purchasing managers index coming in at 51.1.

The reading was lower than the 51.2 seen in November. "Subdued external demand was a key dampener for growth in the closing month of 2024," Jingyi Pan, economics associate director at S&P Global Market Intelligence wrote in the release.

He noted that firms in Hong Kong were concerned about potential U.S. tariffs impacting trade, adding that this may "remain a key driver of sentiment and economic conditions in the new year."

Nippon Steel shares fall as carmaker's president reportedly mulls suing U.S. government

Shares of Japan's Nippon Steel fell 2% after the carmaker's president Tadashi Imai reportedly said that the company might file a lawsuit against the U.S. government, according to a report by Japanese broadcaster Nippon Television.

This comes after U.S. President Joe Biden blocked Nippon Steel's purchase of U.S. Steel after a year-long review, citing national security concerns.

The NTV report quotes Imai as saying, "Our company has the right to be properly reviewed. The history of the review so far and the U.S. government's decision have not been properly reviewed," according to a Google translation of the report in Japanese.

He added, "I think we can take action, including announcing (countermeasures), without spending too much time."

Reuters also reported that Nippon Steel will hold a press conference on Tuesday about the merger.

S&P 500 will rise more than 12% in 2025, UBS says

The market may have more room to run in 2025, according to UBS' David Lefkowitz.

"We expect the bull market to continue with the S&P 500 reaching 6,600 by the end of the year, primarily driven by healthy profit growth of 9%," the firm's chief investment officer of U.S. equities wrote in a recent note. His price target implies about 12.5% upside from Thursday's close.

"That said, there are always risks that investors will have to navigate," Lefkowitz continued.

On that front, Lefkowitz said changes in trade policy under President-elect Trump, fiscal battles in Congress, inflation and the outlook for artificial intelligence could all possibly spur volatility in the coming year.

"But as long as corporate America puts up the numbers, stocks should respond favorably," he said.

The forecast comes after a record-breaking year for the S&P 500. In 2024, the broad market index gained more than 23%, scoring multiple new intraday and closing highs during the period.
