Bank of Japan May Halt Bond Purchases After 2027, Signaling Pivot on Quantitative Tightening

Bank of Japan Eyes Potential Pause in Bond Buying Post-2027, Signaling Shift in QT Stance

Sources close to the matter have indicated that the Bank of Japan (BoJ) is contemplating maintaining its current pace of government bond purchases beyond fiscal year 2027, commencing April of that year. This consideration marks a pivotal moment in the central bank's quantitative tightening (QT) trajectory, potentially halting further reductions in its massive holdings of Japanese Government Bonds (JGBs). While this decision remains unconfirmed, it underscores a discernible divergence of opinions within the nine-member Policy Board. One faction advocates for prioritizing market sentiment and averting significant bond market volatility, whereas another group insists on a steady, albeit slower, pace of reduction to shrink the central bank's considerable balance sheet.

Upcoming Policy Meeting to Shape Future Framework

The BoJ's monetary policy meeting, scheduled for June 15-16, will be crucial for assessing the effectiveness of its current bond-buying reduction plan, which runs until March 2027, and for formulating a new framework for FY2027 and beyond. Market consensus largely expects no alteration to the existing quarterly reduction path. However, the central focus will be on the post-FY2027 strategy: whether the BoJ will continue with a month-on-month reduction or settle on a stable purchase volume of approximately 2.1 trillion yen (around $13 billion) each month.

Evidence Suggests Stance Shift Towards Halting Active Reduction

Four individuals familiar with the BoJ's thinking suggest a growing internal inclination to pause active reduction in bond holdings, citing the progressive advancements already made in this regard. "With maturing bonds naturally redeemed, the central bank's holdings will significantly decrease, fully supporting a pause in active balance sheet reduction," one source stated, with three others concurring. These sources indicate that the BoJ might abandon its annual reduction schedule in favor of an open-ended purchase framework, fixing the monthly buying amount at 2.1 trillion yen.

Interest Rate Hike on the Horizon Amid Inflation Concerns

Beyond potential adjustments to its balance sheet reduction strategy, the BoJ is widely anticipated to raise its short-term policy interest rate from 0.75% to 1% at its upcoming meeting. This would mark the first rate hike since December 2025, pushing the policy rate to a 30-year high. The market has almost fully priced in this increase, with a near 90% probability of a June hike. Investors are also closely monitoring whether inflationary pressures, exacerbated by Middle Eastern conflicts (US-Israel-Iran disputes), might compel the central bank to accelerate its rate-hiking cycle. However, two sources noted that while Japan's financial conditions remain accommodative, there is no immediate necessity for faster or consecutive rate hikes at this juncture, primarily due to the uncertainties surrounding the potential economic impact of the Middle Eastern conflict.

Governor Ueda Emphasizes Gradualism Amidst Energy Price Risks

Governor Kazuo Ueda has recently reiterated the need to guard against the secondary effects of inflation stemming from rising energy prices. Nevertheless, he emphasized that the pace of monetary tightening would remain gradual. Sources suggest that the BoJ is weighing a potential pause in its bond purchase reductions after 2027, aiming to ensure market stability while continuing a measured approach to balance sheet normalization.

Balance Sheet Normalization Progress and Market Dependence

Since Governor Ueda took office in 2024 and initiated the monetary policy normalization process, the BoJ has been consistently reducing its bond purchases, currently trimming them by 200 billion yen quarterly, with the aim of ending decades of ultra-loose policy. As of now, the central bank holds approximately 530 trillion yen in JGBs, representing 49% of the total outstanding market volume. Every move it makes continues to dictate bond yields and the financing costs for Japan's substantial debt.

Tangible Results but Lingering Market Challenges

The balance sheet reduction has yielded tangible results, with the BoJ's holdings decreasing by nearly 20% from their peak in late 2023. Natural redemptions alone are projected to reduce holdings by up to 50 trillion yen annually. The BoJ has previously stated its QT objective is to reduce yield control while avoiding market turbulence. However, current bond market liquidity is weak, and the central bank's exit could create a supply-demand imbalance.

Maintaining Market Stability: A Key Priority

Governor Ueda has recently explicitly stressed the imperative of maintaining bond market stability and preventing drastic yield fluctuations. Hajime Takada, a BoJ Policy Board member and former bond strategist, warned in February that continued reductions in bond purchases could exacerbate pressure on an already oversupplied bond market.

Internal Divergence: Market Stability vs. Debt Reduction

The potential pause in balance sheet reduction is not a foregone conclusion for the BoJ, as some board members remain committed to steadily advancing balance sheet normalization. Naoki Tamura, a former banker and current Policy Board member, voted against the 200 billion yen quarterly reduction plan in June last year, advocating for an immediate reduction of 400 billion yen. Furthermore, Junko Koeda, another Policy Board member, emphasized in a speech this month the need for the central bank to "steadily advance" balance sheet normalization, citing the substantial holdings of government bonds as a core consideration.

The Crucial Trade-off: Short-term Stability Versus Long-term Normalization

The fundamental division lies in the trade-off between short-term market stability and long-term policy normalization. Pausing QT could avert bond market disruptions and accommodate liquidity needs during fiscal reform transitions. Conversely, continuing reductions would accelerate the restoration of the central bank's balance sheet, paving the way for greater future policy flexibility.
