China's central bank in focus drives Asia-Pacific markets upward; S&P and Dow achieve new records.

• The People's Bank of China will hold a rare briefing by PBOC Governor Pan Gongsheng at 9 a.m., which traders in Asia will closely monitor.
• The RBA is predicted to maintain its 4.35% interest rate on Tuesday, according to a poll of economists by Reuters.

On Tuesday, Asia-Pacific markets rose, mirroring gains on Wall Street following the S&P 500 and Dow Jones Industrial Average reaching new closing highs on Monday.

The Dow Jones Industrial Average gained 0.15% to close at 42,124.65, while the broad market index added 0.28% to end at 5,718.57.

The People's Bank of China will hold a rare briefing by Governor Pan Gongsheng at 9 a.m. on "financial support for high-quality economic development," which traders in Asia will closely monitor.

The CSI 300 futures are currently at 3,205.6, slightly below its last close of 3,212.76, before the briefing begins before Chinese markets open at 9:30 a.m.

The RBA is predicted to maintain its 4.35% interest rate on Tuesday, according to a poll of economists by Reuters.

Last week, the Commonwealth Bank of Australia stated in a note that the economic data since the last meeting was either weaker or in line with the RBA's expectations. As a result, CBA anticipates a slightly less hawkish statement, but does not foresee a significant change in language or tone.

Australia's S&P/ASX 200 rose marginally ahead of the RBA decision.

Since Sept. 3, the Nikkei has crossed the 38,000 mark for the first time, while the Topix gained 1% as Japanese markets returned from a holiday. Japan's stock market saw a 1.47% increase.

While the small-cap Kosdaq rose 0.68%, South Korea's stock market saw a 0.6% increase.

The HSI's last close of 18,247.11 was lower than Hong Kong's futures, which were at 18,462.

In the U.S., the Nasdaq Composite increased by 0.14% overnight, matching the gains made by the other two major U.S. stock market indexes.
