Asia-Pacific markets mixed after Fed Chair Powell's rate cut comments lift Wall Street

Asia-Pacific markets were mixed on Tuesday after Federal Reserve Chair Jerome Powell's dovish comments sent Wall Street higher overnight.

Powell said the central bank will not wait until inflation hits 2% to cut interest rates, as the Fed's policy works with "long and variable lags."  So, "if you wait until inflation gets all the way down to 2%, you've probably waited too long," he said.

His comments combined with expectations that Republican presidential candidate Donald Trump's failed assassination attempt will lead to big gains for the party and friendlier fiscal policies pushed the Dow Jones Industrial Average to close at fresh highs.

Hong Kong's Hang Seng index dipped 1.4%, led by consumer stocks, while mainland China's CSI 300 slipped 0.11%.

Japan's Nikkei 225 resumed trading after a public holiday, with the Nikkei 225 gaining 0.36% and the Topix rising 0.70%.

Shares of Japan's TDK Corporation, the sixth largest stock on the Nikkei by weight, jumped more than 4%.

South Korea's Kospi climbed 0.12%, while the Kosdaq swung the opposite direction and fell 1.56%.

Australia's S&P/ASX 200 fell 0.17%, retreating from the index's all-time closing high on Monday.

Following Monday's weaker-than-expected China GDP print, Goldman Sachs lowered its forecast for China's full-year gross domestic product to 4.9% from 5%, while JPMorgan cut its predictions from 5.2% to 4.7%.

"This highlights the need for the government to step up policy support in the second half if they want to ensure around 5% growth for the full year," Hui Shan, chief China economist at Goldman Sachs told CNBC's "Squawk Box Asia" on Tuesday, elaborating that weak domestic demand remains a big issue.
