BOJ's Ueda announces policy review while maintaining negative rates.

The Bank of Japan has left its interest rates unchanged in newly appointed Governor Kazuo Ueda's first policy meeting, while announcing a broad-perspective review of its easing measures. The central bank also kept the tolerance range for 10-year Japanese government bonds unchanged at 50 basis points above and below its target of 0%. Inflation in Japan's capital city ticked higher in April, exceeding forecasts in a Reuters poll for a 3.2% increase. Meanwhile, Japan's unemployment rate rose to 2.8% in March from 2.6% in February, government data showed.
