Shares were mixed Thursday in Asia after Wall Street gave back some of its recent gains on persisting uncertainty over interest rates and inflation. Benchmarks declined in Tokyo, Seoul and Sydney but rose in Hong Kong and Shanghai. U.S. futures were higher while oil prices edged up. Wall Street retreated Wednesday following a set of mixed earnings reports. The pullback also followed comments Tuesday by Federal Reserve Chair Jerome Powell, who signaled that an exceptionally strong U.S. jobs report last Friday would not oblige the central bank to return to a more aggressive stance on raising interest rates to tame inflation.
