Asian shares started the week on a strong note on Monday after a weaker US dollar helped fuel solid gains on Wall Street.
MSCI's broadest index of Asia-Pacific shares outside Japan was up about 1.3% in early trading, while Japan's Nikkei stock average opened up 0.2%.
The dollar had rallied in recent months on expectations that the US Federal Reserve was preparing to hike interest rates later this year. The dollar's strength raised fears for the profits of US multinational companies, so its weakness helped power Friday's gains in US shares.
The dollar plunged on Wednesday after the Fed cut its inflation outlook and its growth forecast. Market players' consensus expectation for the US central bank's interest rate hike have shifted, with a majority of Wall Street's top banks now expecting that the Fed will hold off raising rates until at least September, and the odds for a June hike fading, a Reuters poll showed.
"Due to the light economic calendar in the week ahead, the key issue facing market participants is whether the bout of profit-taking on long dollar positions is over," Marc Chandler, chief currency strategist at Brown Brothers Harriman in New York, said in a note.
Against the yen, the dollar stood at 120.03 yen, nearly flat on the day and well below Friday's session high of 121.205.
