Japan must raise rates, central banker says - Financial Times

Bank of Japan board member Naoki Tamura has said the central bank must raise interest rates, according to the Financial Times — remarks that carry weight because they come from inside the policy committee rather than from outside commentators. Japan has kept borrowing costs exceptionally low for years, so any signal toward tightening is significant for global markets.

The relevance runs through the yen and Japanese government bonds. Higher Japanese yields can narrow the gap with US and European rates, a shift that may influence the yen's value and, by extension, Japanese export competitiveness. Global bond markets also watch Japan closely, since its yields have long anchored expectations elsewhere.

What to watch: whether other board members echo Tamura, and whether upcoming data — inflation and wage growth in particular — support the case for a move. The BOJ's next policy meeting will be the clearest test of whether these comments reflect a broader shift or a single voice.
