BOJ Leaves Interest Rates, Asset Purchases Unchanged

The Bank of Japan (BOJ) maintained its full stimulus, a move anticipated by the market. The BOJ's statement was less optimistic about corporate profits and business sentiment. Following the decision, Japanese shares were sold off, and the yen was bought. Japan faces external risks, including China's slowing economy and global trade tensions, which pose threats to its economy. Central banks worldwide have become more dovish, with the Fed and ECB adjusting their rate hike expectations. Japan's economy is growing at a slow pace, with core CPI under 1%. Economists have revised their expectations for tapering in Japan, now predicting it for late spring at the earliest.
