The Bank of Japan's policy decisions driven by the depreciation of the yen

As the yen continues to weaken further, the Bank of Japan’s (BOJ) policy stance is approaching a major turning point. Former BOJ member Makoto Sakurai pointed out that if current yen depreciation pressures persist, there is a possibility of considering a rate hike as early as March, ahead of the Japan-U.S. summit next month. According to Jin10 reports, this scenario is not just speculation but is emerging as a realistic policy option in response to worsening economic conditions.

Impact of Yen Depreciation on the Economy and Response Challenges

The economic ripple effects of a continued yen decline are complex. Rising import prices could accelerate increases in essential goods such as food and energy. This yen weakness may heighten inflationary pressures and partially offset government fuel subsidies. While short-term price rises are possible, Sakurai states that this situation could actually justify tighter monetary policy.

Under the dual pressures of rising import costs and yen depreciation, traditional adjustment mechanisms may become insufficient to cope with the situation.

More Effective Strategies Than Currency Intervention: Rate Hikes

Historically, government currency intervention has been used to counter yen depreciation. However, Sakurai clearly highlights the limitations of this approach. Currency intervention only provides temporary relief against yen selling pressure. He emphasizes that improving the fundamental supply-demand balance in the market requires more structural policy shifts.

He advocates that the most effective countermeasure to yen depreciation is a gradual rate hike by the BOJ. Such a policy change could make yen-denominated assets more attractive and potentially stimulate demand for yen from foreign investors.

Economic Environment Ahead of March Policy Decisions

One key factor influencing March policy decisions is the trend of the spring wage negotiations (shunto). Strong wage increases expected from corporate and labor union negotiations, combined with inflation concerns, could provide the economic rationale for a policy shift by the BOJ.

Sakurai’s scenario suggests that if yen depreciation worsens, the strong wage growth anticipated in spring negotiations could justify a rate hike in March. The convergence of these various economic indicators is likely to prompt an important policy decision next month.

The severity of yen depreciation’s impact will significantly influence the BOJ’s decision-making criteria.
