"If the Fed isn't going to induce tightening, it's very bullish for risky assets," said Teresa Kong, head of fixed income and portfolio manager at Matthews Asia. "We should be seeing a mild rally in Asian assets and currencies."

The S&P 500 closed at a record high on Wednesday and the Dow Jones Industrial Average closed above 33,000 points for the first time, bolstered by the Fed's strong economic forecast and Powell's comments that it is too early to discuss tapering-off measures.
