Australia Outperforms Asian Stocks After RBA

Asian stocks closed mostly higher on Tuesday with Australia's benchmark S&P ASX 200 leading gains by 2.6 percent after the Reserve Bank of Australia (RBA) left the door open for future easing at its June policy meeting.

Sentiment across the region was much improved after a series of upbeat global manufacturing reports. Japan's benchmark Nikkei crossed 14,000 points to hit a new one-month high, the Shanghai Composite rose to a one-week high and South Korea's Kospi was steady at the 1,855 mark.

Global PMIs Support

Strong manufacturing reports in the U.S. and Europe lifted global equity markets overnight. Manufacturing activity in the U.S. edged higher in June to 50.9, according to the Institute for Supply Management, just above expectations for 50.5. A reading above 50 indicates expansion in the sector.

In the euro zone, the Purchasing Managers' Index (PMI) showed an uptick to 48.8, the highest reading since March 2012.

Sydney Up 2.6%

In a widely-expected move, the Australian central bank left its cash rate unchanged at 2.75 percent. The RBA maintained its easing bias and stated that the Australian dollar was still at high levels. In reaction, the currency lost nearly 1 percent to fall below the $0.92 handle against the greenback.

"Overall, it seems the RBA is very comfortable with the current policy setting. It feels the AUD will depreciate further over time, which would help foster a rebalancing of growth in the economy," said Stan Shamu, market strategist, IG.
