Wall Street was mixed, paring sharp early losses after disappointing data from China and a slump in Japanese stocks outweighed better-than-expected reports on US jobs and housing.
In China, the preliminary reading for a Purchasing Managers' Index of manufacturing was 49.6 in May, according to HSBC and Markit Economics data. In Japan, the Topix plunged 6.9 per cent.
Yesterday's comments by US Federal Reserve Chairman Ben Bernanke suggested the central bank might ease back its bond-buying program as soon as at its next meeting, while also stressing the risk of withdrawing stimulus measures too soon.
Fed officials today sought to soothe investors' concerns. James Bullard, president of the St Louis Fed, said he didn't think the bank's policy committee was "that close" to tapering bond purchases and when it did start to pull back it would be slowly.
"The market is struggling with conflicting language from Fed officials as to the timing of potential tapering of asset purchases, slowing growth in China and after Japan's decline in equities," Ryan Larson, the Chicago-based head of US equity trading at RBC Global Asset Management, told Bloomberg News.
