The Bank of Japan decided unanimously on Tuesday to keep interest rates at -0.1%, while also sticking to its yield curve policy that keeps the upper limit for 10-year Japanese government bond yield at 1% as a reference. BOJ Governor Kazuo Ueda says more scrutiny is needed to ascertain if a "positive" wage-inflation cycle has fallen in place in Japan. Ueda says any underlying decline in real wages won't impede the normalizing of monetary policy if wages are expected to rise and consumer inflation continues to slow, which could still turn real wages positive.
