Japan's interest rate hike did not meet expectations, and the yen exchange rate faces short-term pressure.

The Bank of Japan announced a 25 bps rate hike on December 19, raising the policy interest rate to 0.75%, the highest since 1995. However, this decision did not trigger yen appreciation as the market expected; instead, the USD/JPY exchange rate continued to rise.

Why Did the Market React Calmly?

The key lies in Governor Ueda Kazuo’s overly cautious statements. Although the statement confirmed that if economic and price trends meet expectations, the BOJ will continue to raise rates, Ueda did not provide a clear timetable for the next rate hike during the press conference. He emphasized the difficulty in pre-determining the neutral interest rate level, only stating that they plan to revise the neutral rate estimate range (currently 1.0%–2.5%) at an appropriate time.

ANZ Bank strategist Felix Ryan pointed out that although the BOJ has initiated a rate hike cycle, the USD/JPY exchange rate has risen, reflecting investors’ lack of confidence in the future pace of rate hikes by the central bank. He believes that the market’s interpretation of the policy is more “dovish” rather than “hawkish.”

Long-term Challenges Facing the Yen

According to ANZ Bank’s forecast, while rate hikes in Japan will continue, the yen’s relative performance among G10 currencies will still lag by 2026. The main reason is that the interest rate differential environment is unfavorable for the yen. The bank predicts that by the end of 2026, the USD/JPY exchange rate will reach 153.

Fidelity Investment Management strategist Masahiko Loo maintains a medium-term target of 135–140 for USD/JPY. Factors supporting this view include the continued easing policy of the Federal Reserve and Japanese investors actively increasing their foreign exchange hedging ratios.

What Is the Market Really Expecting?

Overnight index swap market data shows that investors expect the BOJ to raise rates to 1.00% by Q3 2026. Nomura Securities pointed out that only when the forward guidance from the BOJ hints that the rate hike timing is earlier than this (such as as early as April 2026 or sooner) will the market see it as a genuine hawkish signal, triggering yen buying.

In other words, without significantly adjusting the neutral rate estimate, Governor Ueda is unlikely to convince the market in the short term that the ultimate rate will rise substantially. This is why, although the December 19 rate hike was in line with expectations, it did not provide strong support for the yen. Japan’s rate hike path remains long and arduous, and market confidence still requires time and clearer policy signals.
