Japan's Bond Yields Surge Amid BoJ Policy Normalization

The Bank of Japan's shift from ultra-accommodative monetary policy has led to a significant increase in bond yields, marking a break from decades of exceptionally low borrowing costs. Since early 2022, Japan's 10-year government bond yield has risen from around 0.2% to 2.7% in July 2026.

This rise is primarily driven by the BoJ's normalization of monetary policy, including its exit from Yield Curve Control and negative interest rates. The central bank raised its policy rate from -0.1% in April 2024 to 1.0% in June 2026, as inflation remained above its 2.0% target.

The impact on government finances will unfold gradually, supported by Japan's long debt maturity profile and stable investor base. However, maintaining favorable debt dynamics is Japan's key challenge, with public debt exceeding 200% of GDP.
