BoJ Affirms Gradual Normalization, Pledges to Cap Disorderly Yield Spikes

The Bank of Japan (BoJ) has signaled its intent to continue gradually normalizing monetary policy, guided by inflation that is approaching its 2% target.

This policy is supported by a virtuous cycle of rising wages and prices, with recent data showing strong wage demands and core inflation at the target level.

However, to ensure market stability amid rising bond yields, the BoJ has also promised to intervene flexibly if there are any sudden, disorderly spikes.

The Bank of Japan (BoJ) is carefully navigating the path toward monetary policy normalization, balancing its goals with the need for market stability.

The central pillar of the BoJ's strategy is achieving a stable and durable 2% inflation target. Governor Ueda's recent remarks confirm that progress is being made, driven by what he calls a 'virtuous cycle' between wages and prices. First, the 2025 spring wage negotiations ('shuntō') resulted in a 34-year high settlement of 5.25%. Second, unions are demanding an even higher 5.94% for 2026, suggesting strong wage momentum. Third, this has translated into inflation, with core CPI hitting the 2.0% target and 'core-core' CPI, which excludes fresh food and energy, running hotter at 2.6%. This data provides the justification for the BoJ to continue its gradual exit from ultra-loose policy.

However, this normalization creates a challenge in the bond market. As the BoJ ended its negative interest rate policy (NIRP) and yield curve control (YCC), and began tapering its purchases of Japanese Government Bonds (JGBs), bond yields have naturally risen. The 10-year JGB yield recently climbed to around 2.12%, a multi-decade high, sparking concerns about financial stability. This is precisely why Governor Ueda has repeatedly emphasized that the BoJ will respond flexibly to 'exceptional' or 'disorderly' spikes in yields. This acts as a verbal safety net, reassuring markets that while yields are allowed to reflect economic fundamentals, the central bank will not tolerate excessive volatility.

This stance is not new but a consistent message built over the past year. The journey began with the end of NIRP/YCC in March 2024, followed by gradual rate hikes. Throughout this period, officials have consistently linked policy moves to the wage-price dynamic while simultaneously preparing the market for a hands-off approach to yields, barring emergencies. In essence, the BoJ is communicating a clear and predictable framework: policy will tighten as long as the wage-inflation cycle holds, but a stability backstop is always ready if needed.

Core-Core CPI: An inflation measure that excludes both fresh food and energy prices. It is considered a better indicator of the underlying inflation trend as it is less affected by volatile commodity prices.
JGB (Japanese Government Bond): A bond issued by the Japanese government to finance its spending. The yield on these bonds is a key benchmark for interest rates in Japan.
Shuntō: An annual event in Japan where labor unions negotiate with employers for wage increases. The outcomes are a critical indicator of wage trends and a key factor in the BoJ's policy decisions.
