HONG KONG (Reuters) - Asian stocks slipped on Wednesday as investors took profits before a U.S. central bank policy meeting that could signal how much monetary tightening to expect during the remainder of the year, with an immediate rate hike fully priced in by markets.
Though recent data, particularly out of China, has fueled a rally in Asian equities since the start of the year, investors are expecting more headwinds for emerging markets due to an increasingly hawkish Fed.
"The positive sentiment towards emerging markets is not sustainable as the interest rate differential advantage in Asia's favor is likely to reduce in the coming months," said Frances Cheung, head of rates strategy for Asia ex-Japan at Societe Generale in Hong Kong.
The MSCI's broadest index of Asia-Pacific shares outside Japan was down 0.3 percent after posting its second-biggest daily gain this year in the previous session.
Japan's benchmark Nikkei average was down 0.3 percent while stocks in South Korea and Australia declined 0.2 and 0.5 percent respectively.
