Bank of Japan struck a more urgent tone in the Summary of Opinions from its March meeting, warning of the risk of “falling behind the curve” if policy tightening lags underlying inflation dynamics. With real interest rates still deeply negative and price pressures showing signs of persistence, policymakers acknowledged that delayed action could eventually force more rapid and disruptive tightening, posing a greater risk to the economy.
While the baseline remains “gradually proceeding with rate hikes”, the discussion revealed growing openness to adjusting the pace of hikes. Members indicated that rate increases may need to proceed “without long intervals between adjustments” and, if necessary, “without hesitation,” particularly if inflation trends continue to firm. This marks a subtle but important shift from a purely cautious stance toward a more proactive tightening approach.
A key concern is the rising risk of second-round effects. BoJ noted that wage growth is gaining traction amid labor shortages, while firms are increasingly passing through higher costs, amplified by “excessive depreciation of the Yen”. The combination of stronger wage-price dynamics and a weaker currency is seen as increasing the likelihood that underlying inflation could exceed the 2% target in a sustained manner.
While higher oil prices could weigh on growth, policymakers stressed that the current environment still supports an ongoing uptrend in prices. In this context, Yen weakness becomes a critical factor, as further depreciation could intensify imported inflation and force the BoJ to accelerate tightening beyond its current projections.
