Bank of Japan's Pivot: From Fighting Deflation to Curbing Overheating

The recently released minutes from the monetary policy meeting unveil a quiet but profound shift within the Bank of Japan. The central anxiety among policymakers has moved from the decades-long specter of deflation to a new fear: that inflation could spiral out of control.

A Rewritten Inflation Story: The Risks of Waiting Are Real

During the discussions, one board member pinpointed the core issue. With core CPI steadily approaching the 2% target, the central bank's policy rationale has undergone a fundamental change. The primary objective is no longer "how to push inflation up," but "how to prevent it from soaring too high."

This shift stems from a crucial reassessment: the premise that "the risk of waiting is minimal" no longer holds. Persistent and robust underlying price pressures are forcing the BOJ to withdraw its ultra-easy policy faster. Some even argued that to establish a foundation for long-term policy normalization, the pace of rate hikes must be more aggressive than what financial markets currently anticipate.

The Rate Hike Path: More Flexible, More Forceful

Discussions on the future interest rate trajectory featured two notable keywords: "flexible" and "forceful."

  • Flexible Response: Members emphasized that the bank should not be bound by a pre-set, gradualist timetable, but adopt a "flexible approach" to respond to a rapidly changing external financial environment.
  • Forceful Stance: More strikingly, one member explicitly proposed discussing "larger rate hike measures." This is seen as a strong signal to markets of the bank's determination to rein in inflation. The current policy rate stands at 1%.

Targeting the "Neutral Rate": A Long Road Ahead

Despite the hike from negative territory, the BOJ's tightening journey is far from over. Internal estimates place the "neutral rate"—which neither stimulates nor restrains the economy—within a range of 1.1% to 2.5%.

This means the current 1% policy rate remains below the lower bound of that range. The minutes indicate that there is a growing consensus among policymakers to steer rates toward this neutral level, ensuring monetary policy has sufficient buffer and agility against economic shocks. The "second half" of this normalization process may prove more rapid and forceful than many observers expect.
