BOJ Weighs Further Bond Purchase Reductions as Yield Curve Normalization Continues

The Quick Take

• The Bank of Japan is considering additional reductions in its monthly government bond purchase amounts under its ongoing balance sheet normalization program.
• Further BOJ purchase cuts would allow longer-dated JGB yields to rise more freely, continuing the yield curve control exit initiated in 2024.
• A purchase reduction signals BOJ confidence that Japanese inflation can sustain at target without aggressive bond market accommodation.

The Bank of Japan's internal deliberations over further reductions in monthly government bond purchases represent the next phase of its unprecedented exit from yield curve control, a policy that had artificially capped 10-year JGB yields for nearly a decade. BOJ Governor Ueda's framework has been one of cautious, data-dependent normalization — reducing purchase amounts gradually to allow the JGB market to rediscover price discovery without triggering the sharp yield spike that could destabilize Japan's highly indebted government balance sheet. The weighing of additional cuts reflects growing BOJ confidence that Japan's wage-price dynamic is sufficiently durable to sustain inflation at target.

A further reduction in BOJ bond purchases would have immediate ripple effects through global fixed-income markets: Japanese life insurers and pension funds, which hold trillions of yen in domestic JGBs as liability-matching assets, would face mark-to-market losses as longer-dated yields rise. The yen-carry trade dynamic would also shift — higher Japanese rates reduce the interest rate differential that makes borrowing in yen attractive for global investors, potentially triggering carry trade unwinding that strengthens the JPY and pressures risk assets globally. Peer central banks including the ECB and Fed would watch the BOJ normalization for lessons on how to manage balance sheet reduction without triggering market dysfunction.

Watch BOJ's next Monetary Policy Meeting minutes and any Governor Ueda press conference for specific commentary on the purchase reduction timeline and magnitude. The macro variable is Japan's wage growth: the BOJ's normalization confidence is anchored in data showing sustained wage increases above 3% in the Shunto spring wage negotiations, and any sign of wage growth deceleration would pause the purchase reduction agenda. Monitor 10-year JGB yields weekly as the real-time gauge of whether the market is absorbing reduced BOJ purchases smoothly or requires any tactical backstop purchases to prevent disorderly yield moves.
