The dollar, euro and yen treaded water on Tuesday in Asia, as the market was quiet with Tokyo on holiday and traders awaiting direction after the latest readings on global manufacturing activity failed to show clear economic trends.

In Asia, the Australian dollar was the biggest mover in an otherwise sedate session, rising after the Reserve Bank of Australia (RBA) left interest rates unchanged.

Australia's central bank kept its cash rate steady at a record low of 2.0 per cent on Tuesday as widely expected, but said low inflation offered scope to ease further if needed.

While the question still appeared to be when and not if the RBA could cut rates in the near future, commentators suggested that the Aussie moved more on factors other than monetary policy.

"The recent track record suggests policy expectations have not been the dominant driver," wrote Todd Elmer, head of Citi's G10 strategy in Singapore. "AUD has actually gained as interest rate expectations have declined sharply, at least partly reflecting gains on the basis of rising risk appetite."

"With recent Fed hawkishness having done little to upset stronger sentiment and rising asset prices, there could be further upside for AUD on this basis yet."

The Aussie was up 0.8 per cent at $0.7200. It touched a 6-1/2-year low of $0.6892 early in September when risk appetite globally was at a low ebb amid China worries. But the currency rebounded to as high as $0.7382 in mid-October as appetites improved.

The dollar index was barely changed at 96.907 after drifting between 96.635 and 96.965 all of Monday. The euro was hemmed in a tight $1.1000 to $1.1053 range and last stood at $1.1012.

Against the yen, the greenback was equally restrained, trading nearly flat at 120.73, while the euro was steady at 133.94 yen.

A crop of industry surveys on Monday pointed to another subdued month for manufacturers across the globe, though a rise in new orders offered hope the United States might have seen its worst.

"Currencies, for the most part, took a back seat in a largely so-so session for broader financial markets... investors appear to be in a holding pattern ahead of bigger event risks later in the week," said Raiko Shareef, currency strategist at BNZ.

US jobs data on Friday remains the key feature for the week, offering the markets an opportunity to see if the report can give the data-dependent Federal Reserve enough ammunition to hike rates in December.
