(Sharecast News) - Asia-Pacific markets finished Wednesday's trading session with a mixed performance, as investors continued to digest the Bank of Japan's (BOJ) recent policy adjustment and looked ahead to the upcoming decision from the US Federal Reserve.

The BoJ's move to raise interest rates for the first time in 17 years and abandon its yield curve control policy on Tuesday propelled the Nikkei beyond the 40,000 mark for the first time in nearly two weeks.

"Most Asian stock markets are seeing higher trading, influenced by the positive performance of global markets and the recent monetary policy announcements from the Bank of Japan, People's Bank of China, and the Reserve Bank of Australia," said TickMill market analyst Patrick Munnelly.

"Investors are also cautiously anticipating the monetary policy decision from the US Fed later in the day."

Munnelly noted that the BoJ made a historic shift by ending eight years of negative interest rates and implementing the first-rate hike in 17 years.

"It is widely anticipated that the Fed will maintain unchanged interest rates, but the accompanying statement from the central bank could have a significant impact on rate outlook."

China central bank keeps rates on hold

In economic news, the People's Bank of China opted to keep its one- and five-year loan prime rates (LPR) steady at 3.45% and 3.95%, respectively, as had been widely anticipated by markets.

The one-year rate serves as the reference rate for the majority of household and corporate loans, while the five-year rate acts as the benchmark for many property mortgages.

In a separate development, Reuters reported that the PBoC undertook a restructuring of its monetary policy committee.

The newly-reconfigured committee now included Wu Qing, the head of China's securities regulator, and Xuan Changneng, vice governor of the central bank.
