Hong Kong was dragged down by a sharp fall in HSBC Holdings on Tuesday, after the bank's earnings report disappointed the market, while the Australian dollar rose after the Reserve Bank of Australia cut interest rates to an all time low.

HSBC (HBC), which announced its interim earnings after the market closed on Monday, slumped 5% -- its largest daily decline since July 2012. Although the bank reported a 23% increase in net profit for the first half of the year, its stock was hit by fears that its revenues were being affected by slowing growth in emerging markets.

As the single largest constituent in Hong Kong's Hang Seng Index , accounting for around 15% of the benchmark, the bank's decline weighed on the entire market. The Hang Seng fell 1.3% to 21,923.70.

The Australian dollar (AUDUSD), which hit a three-year low against its U.S. counterpart on Monday, picked up after RBA decided to cut rates to a record low of 2.5%. Expectations for lower interest rates were high, with all 15 economists surveyed by The Wall Street Journal forecasting a rate cut.

The currency was at $0.8991 late in Asia, compared to $0.8913 late Monday, and was lifted after the central bank omitted to say that there remains space for further cuts.

The central bank has now cut interest rates eight times since late 2011, as a weakening mining sector prompted policy makers to use monetary policy to support growth in other parts of the economy.

The S&P/ASX 200 fell 0.1% to 5,105.60.

The U.S. dollar (USDJPY) weakened against the yen early Tuesday, though it recovered as the day progressed. The greenback was at Yen98.37 late in Asia, compared with Yen98.30 late Monday in New York. The Nikkei closed 1% higher at 14,401.06.

"In thinly traded markets typical of mid-summer like now, index movements can be more vulnerable than usual to single-factor trading patterns, such as reflexive weak-yen based-stock buying," said Yoshihiro Okumura, general manager at Chibagin Asset Management.

Shares in Sony Corp. (SNE) ended 4.6% lower after the company rejected the proposal made by hedge fund investor Daniel Loeb to sell part of its entertainment business through a public offering.

Mitsubishi Materials Corp. (MIMTF) rose 3.1% in Tokyo after the Nikkei reported that its group operating profit for the first quarter is believed to have risen more than 30% on year to about Yen15 billion, driven by an improvement in its copper segment and a weaker yen.

Also in Tokyo, Toshiba Corp. (TOSYY) outperformed the broader market, up 1.4% after a Nikkei report said that the company plans to build a NAND flash memory factory in a joint venture with SanDisk, with the total investment estimated to be Yen400 billion.

In Taiwan, where the Taiex fell 1.2% to 8,038.91, phone maker HTC Corp. (HTCXF) dropped 2.9% after it posted a 37% on-year drop in revenue in July. The technology firm's stock has been under pressure in recent months and has lost 50% of its value so far this year.

South Korea's Kospi Composite fell 0.5% to 1,906.62, the Shanghai Composite Index rose 0.5% to 2060.50, and Singapore's Strait Times index was last down 0.7%.
