Bank of Japan Plans 25-Basis-Point Hike to Maintain Market Stability

The Bank of Japan (BOJ) is expected to favor a 25-basis-point interest rate increase at its September 17-18 policy meeting. By opting for incremental tightening, the bank aims to avoid market turbulence. This approach balances the requirements of policy normalization with the need to assess how previous hikes have affected the Japanese economy.

Policy officials are weighing the pace of further adjustments as they move away from years of ultra-loose monetary policy. Although inflationary pressures from a weak yen and a tightening labor market persist, the central bank remains cautious regarding aggressive moves that could trigger financial instability.

"Doing a 50-point hike could be seen as a sign of the BOJ's desperation and put the market's focus on the risk of it being behind the curve," said Nobuyasu Atago, chief economist at Rakuten Securities Economic Research Institute, according to a report by the Press News Agency.

Assessing the Cumulative Impact

The BOJ is considering a shift toward a quarterly pace for future rate hikes. This cadence provides policymakers with time to monitor how the economy absorbs each adjustment. This strategy differs from the rapid shifts that preceded the 1989 asset bubble collapse, which serves as a cautionary tale for modern Japanese monetary policy.

"We hope to continue raising interest rates as financial conditions remain accommodative. On the other hand, we've raised rates five times so far, so we need to carefully assess the cumulative impact on the economy," said BOJ Governor Kazuo Ueda.

The Neutral Rate Framework

Bank staff estimate the neutral interest rate, defined as the rate where monetary policy is neither stimulative nor restrictive, to be between 1.1% and 2.5%. A move to 1.25% in September would place the benchmark rate at the lower end of this estimated range.

By keeping hikes limited to 25 basis points, the central bank aims to reach this neutral territory without inducing the market shock that often accompanies larger, unexpected shifts. The BOJ prioritizes a steady trajectory that supports stability while addressing inflationary risks.
