The governor of the Bank of Japan has signaled that the central bank must continue raising interest rates to bring inflation under control, reinforcing expectations that Japan’s long era of ultra-loose monetary policy is firmly in the past.
Bank of Japan Governor Kazuo Ueda reiterated this week that further interest rate increases remain necessary as the central bank works to keep rising prices in check. The comments underscore a meaningful shift in Japan’s monetary policy stance — one that carries consequences not just for Japanese households and businesses, but for global financial markets as well.
Japan spent decades holding rates near or below zero in an effort to fight deflation, a persistent fall in prices that can trap an economy in slow growth. That approach kept borrowing costs extremely cheap and made the yen a popular funding currency for global investors. The recent pivot toward tighter policy marks a historic departure from that era.
When a major central bank raises rates, it typically strengthens its currency, raises borrowing costs, and can slow economic activity. For Japan, higher rates also affect what is known as the “yen carry trade” — a strategy where investors borrow cheaply in yen and invest in higher-yielding assets elsewhere. As Japanese rates rise, that trade becomes less attractive, which can prompt investors to unwind positions and move money back into Japan.
Ueda’s remarks signal the Bank of Japan is not satisfied that inflation is durably anchored at its target and sees room for further tightening. Japan’s inflation has run above the central bank’s 2% goal for an extended stretch, driven in part by higher food and energy costs as well as stronger wage growth — a dynamic the Bank of Japan has said it needs to see sustained before fully normalizing policy.
The pace of future rate increases will depend on incoming economic data, including wage trends and whether domestic demand holds up. Global factors — such as the outlook for the U.S. economy and the direction of the dollar — will also weigh on the Bank of Japan’s decisions, given Japan’s heavy reliance on exports.
Markets will be watching the Bank of Japan’s next policy meeting closely for any fresh signals on the timing and size of the next rate move.
