TOKYO, Feb 27 (Reuters) - Asian shares edged higher on Wednesday and the dollar fell to a three-week low after Federal Reserve Chairman Jerome Powell reinforced the U.S. central bank's recent shift towards a more "patient" approach on policy in the face of a slowing economy.
MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS added 0.1 percent in early trade, not far from its five-month high marked on Monday.
Japan's Nikkei share average .N225 gained 0.4 percent, while Australian stocks .AXJO rose 0.3 percent.
The Fed is in "no rush to make a judgment" about further changes to interest rates, Powell told U.S. lawmakers on Tuesday as he spelled out the central bank's approach to an economy that is likely slowing.
In two hours of testimony to the Senate Banking Committee, Powell elaborated on the "conflicting signals" the Fed has tried to decipher in recent weeks, including disappointing data on retail sales and other aspects of the economy that contrast with steady hiring, wage growth, and ongoing low unemployment. evidence of the hot and cold economy was in evidence overnight, with weaker-than-expected U.S. housing data and a rosy consumer confidence report. homebuilding tumbled to a more than two-year low in December as construction of both single and multi-family housing declined, which overshadowed the rebound in consumer confidence in February after three months of declines. contrasting data points left Wall Street underpowered, with the benchmark S&P 500 .SPX , the Dow Jones Industrial Average .DJI and the Nasdaq Composite .IXIC closing down 0.1 percent each.
"Chairman Powell's comments were neutral and the economic data released overnight was mixed, insufficient to provide implications for the Fed's policy and directions to the market," said Yasuo Sakuma, chief investment officer at Libra Investments.
In the currency market, the dollar was softer after the Fed chief's testimony, with its index .DXY measure against major peers dipping to its lowest in three weeks overnight. It last traded flat at 96.079.
