BOJ’s Noguchi Calls for Cautious, Gradual Interest Rate Hikes to Sustain Inflation Goals

Bank of Japan (BOJ) board member Asahi Noguchi emphasized the need for a carefully calibrated approach to raising interest rates, warning that moving too aggressively could undermine the country’s progress toward stable inflation. Speaking Thursday, Noguchi said the central bank must adopt a “measured, step-by-step approach” to tightening monetary policy to avoid disrupting the momentum behind corporate wage increases—an essential factor in achieving the BOJ’s 2% inflation target.

According to Noguchi, a rapid pace of rate hikes could weaken businesses’ willingness to raise wages, ultimately pushing the inflation goal further out of reach. At the same time, he acknowledged that increasing rates too slowly poses its own risks, potentially destabilizing both economic activity and price trends. Striking the right balance, he said, is critical for guiding the Japanese economy toward sustainable growth.

While price stability remains the BOJ’s primary policy objective, Noguchi noted that exchange-rate movements and asset prices continue to play a significant role in how monetary policy impacts the broader economy. He pointed out that yen depreciation, in particular, can raise economic activity and price levels by influencing both exports and import costs—making currency trends a key consideration in policy decisions.

Noguchi stressed that the central bank must thoroughly evaluate how various economic channels affect Japan’s overall outlook. This includes assessing how shifts in the yen, changes in corporate behavior, and global economic conditions interact with domestic demand. Using the policy rate as a flexible tool, he said, allows the BOJ to fine-tune the degree of monetary accommodation based on evolving economic signals.

His comments come as markets closely watch the BOJ for signs of further policy normalization after years of ultra-low interest rates. Noguchi’s message reinforces the bank’s cautious stance: a commitment to supporting economic recovery while ensuring inflation becomes stable and self-sustaining.
