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

Mainland Chinese stocks fell to a five-year low while Australian stocks smashed all-time records on Wednesday.

The S&P/ASX 200 gained 1.06% and closing at 7,680.7, surpassing its previous record high of 7,632.8 set back on August 13, 2021.

This comes after the country's fourth-quarter inflation rate was lower than expected at 4.1%, its lowest level since the quarter ended December 2021.

China's CSI 300 slid to a five-year-low, sinking 0.91% to close at 3,215.35 after China's manufacturing activity shrank for the fourth straight month in January, with the official manufacturing purchasing index at 49.2. Hong Kong's Hang Seng index dropped 1.78%.

Other Asia-Pacific markets were mixed. Japan's Nikkei 225 closed 0.6% higher at 36,286.71, while the broad based Topix also ended nearly 1% higher at 2,551.10.

South Korea's Kospi was down 0.07% at 2,497.09, while the small cap Kosdaq saw a bigger loss of 2.4% closing at at 799.24.

Overnight in the U.S., the three major indexes ended the day mixed as Wall Street also waits for the latest Fed decision on interest rates.

The Fed funds futures market has priced in a 97% probability that the central bank will leave rates unchanged, according to the CME FedWatch tool, so investors are instead left anticipating a shift in the policy statement that will close out the meeting.

The S&P 500 slipped 0.06%, while the Nasdaq Composite pulled back 0.76%. In contrast, the Dow Jones Industrial Average added 0.35% to end at 38,467.31, marking its seventh record close this year.

China's official manufacturing PMI in line with expectations for 49.2 in January

China's factory activity contracted for a fourth consecutive month in January, though the official manufacturing purchasing managers' index expectedly rebounded to 49.2 from 49 in December, a six-month low. January's reading is in line with the median forecast in a Reuters poll.

The official non-manufacturing managers' index rose to 50.7 in January from 50.4 in December, according to data from the National Bureau of Statistics released Wednesday. Strength in the country's services industry helped offset weakness in the construction sector amid a slump in the real estate sector.

A PMI reading above 50 indicates expansion in activity, while a reading below that level points to a contraction.

Trump vs. Biden: Goldman Sachs names the global stocks to play the U.S. elections

As the U.S. presidential election comes into the spotlight, Goldman Sachs has assessed the potential impact on global markets by changes in regulation, taxation, and other government policies.

The Wall Street bank said in a note that if former President Donald Trump returns to power, risks would increase around potential tariffs on European exports and reduced U.S. support for Ukraine. However, it sees U.S. subsidiaries of foreign companies potentially gaining if Trump delivers on a cut to corporation taxes.

The investment bank has also revealed the sectors and stocks most likely to be shielded from President Trump's proposed 10% tariff on all U.S. imports.

Oil rises as IMF boosts growth forecast, market braces for U.S. response to drone attack

Oil prices rose on Tuesday after the International Monetary boosted its growth forecast and as the market braced for the U.S. response to a deadly drone attack on its troops in the Middle East.

The West Texas Intermediate contract for March was last up $1.07, or 1.39%, to trade at $77.85 a barrel. The Brent contract for March last traded at $82.98 a barrel, up 58 cents or 0.70%.

The IMF forecast economic growth of 3.1% this year, up 0.2 percentage points from its October forecast, due to a resilient U.S. economy and stimulus in China.

Geopolitical tensions in the Middle East, meanwhile, are simmering after militants killed three U.S. soldiers in a drone attack in Jordan. The U.S. holds Iran-allied militants responsible and has vowed to respond.

Though the response in the oil market to Mideast turmoil has been muted, analysts warn that direct confrontation between Iran and the U.S. could send prices higher.

Geopolitical shocks could lead to 'growth disappointments,' says IMF

The International Monetary Fund slightly increased its global growth forecast for 2024, noting that a hard landing is looking less likely — but cited ongoing geopolitical conflicts as potential overhangs to global growth.

"New commodity price spikes from geopolitical shocks––including continued attacks in the Red Sea — and supply disruptions or more persistent underlying inflation could prolong tight monetary conditions. Deepening property sector woes in China or, elsewhere, a disruptive turn to tax hikes and spending cuts could also cause growth disappointments," the organization wrote in its World Economic Outlook Update for 2024.

Nonetheless, the IMF raised its global growth projection to 3.1% in 2024, which is 0.2% higher than its forecast from October 2023.

Goldman Sachs' David Kostin expects the market rally to broaden in 2024

This year, it's time for the other 493 stocks in the S&P 500 to shine, according to Goldman Sachs' chief U.S. equity strategist David Kostin.

While the "Magnificent 7" tech titans led last year's market outperformance, Kostin believes that the rally is due to broaden this year.

"We'll take the Russell 2000 and the small caps," he said on CNBC's "Squawk on the Street" on Tuesday morning.

As a strong economy causes the Federal Reserve to begin cutting interest rates this year, Kostin believes that this will benefit the small-cap names with less stable balance balance sheets and more floating rate debt.

"Some of the net interest income for a lot of companies with strong cash positions should diminish over time as the Fed is cutting," Kostin added.
