GLOBAL MARKETS-Asian shares subdued, focus turns to central bank meetings
* Fed tapering expectations keeps Asian shares subdued
* Dollar index near two-month high
* Central banks in Japan, Thailand and Canada in focus
* Higher-than-expected Australia inflation hurts local shares, lifts Aussie
TOKYO, Jan 22 (Reuters) - Asian share markets struggled for inspiration on Wednesday, hampered by expectations of further reductions in the U.S. Federal Reserve's stimulus and ahead of central bank meetings in Japan and Thailand.
The dollar remained broadly supported, trading around its highest level since mid-November against a basket of currencies, with many investors expecting the Fed to trim its bond buying further next week.
"Investors started the year with an optimistic global economic outlook. But so far, we haven't seen much in the way of additional proofs for such optimism," said Daisuke Uno, chief strategist at Sumitomo Mitsui Bank.
Japan's Nikkei was almost flat, while MSCI's broadest index of Asia-Pacific shares outside Japan was off 0.1 percent.
Australian shares fell 0.8 percent, extending losses after an unexpectedly large spike in inflation reduced the prospects of a rate cut, though the data also helped to lift the Australian currency 0.6 percent to $0.8855.
In a mixed day on Wall Street the Standard & Poor's 500 Index rose 0.28 percent and the Nasdaq Composite Index gained 0.67 percent, while the Dow Jones industrial average fell 0.27 percent on disappointing earnings by three of its components.
The dollar index stood at 81.072, having risen as high as 81.388 on Tuesday.
The euro traded at $1.3566, not far from a two-month low of $1.3508 hit on Monday while the yen stood at 104.30 yen , not far from a five-year high of 105.42 yen hit on Jan. 1.
The Bank of Japan is widely expected to keep its policy on hold on Wednesday, although some investors are looking for signs of further easing from its Governor Haruhiko Kuroda.
The Canadian dollar drooped near a four-year low ahead of a policy announcement from the Bank of Canada later in the day, with many traders speculating the bank could shift its policy bias from neutral to easing.
The Canadian dollar traded at C$1.0967 per U.S. dollar , having touched $1.1019 on Tuesday.
In contrast, investors expect the Fed to trim its monthly bond buying by around $10 billion to $65 billion at its Jan 28-29 meeting, the last meeting under outgoing Chairman Ben Bernanke, after it cut purchases by $10 billion in December.
Such a move could unsettle emerging markets, as foreign investors re-route funds back towards U.S. markets on further signs of a healthier economy.
THAI BANK MEETS
The Thai central bank also meets on Wednesday and could cut rates to shore up a sagging economy hit by months of political unrest, putting renewed pressures on the Thai baht.
Bangkok has declared a 60-day state of emergency, saying it wants to prevent any escalation of more than two months of protests aimed at forcing Prime Minister Yingluck Shinawatra from power.
The baht stood little changed at 32.87 to the dollar, not far from a four-year low around 33.13 hit earlier this month.
"Thai financial markets are relatively calm for now. But if the political standoff drags on, then there will be delays in infrastructure investment and larger economic implications," said Yukino Yamada, senior strategist at Daiwa Securities.
Turkey, another emerging economy hit by political turmoil, saw its currency plunge to a record low on Tuesday after its central bank shied away from hiking interest rates, bowing to what many investors see as pressure from a government bent on maintaining growth ahead of elections.
