Bank of Japan chief Kazuo Ueda said Thursday he is still not confident about the prospect of the nation attaining the central bank’s 2 percent inflation target on the back of wage growth, describing the outcome of forthcoming spring pay negotiations as “a focal point.” Speaking at a press conference after a two-day meeting of Group of 20 finance chiefs, Ueda stressed the need for strong wage growth to see if a virtuous cycle of price and pay hikes has been set in motion.
