The Bank of Japan has approved a significant acceleration of its exchange-traded fund sales, increasing the annual disposal pace to approximately ¥860 billion at book value, up from ¥330 billion. Despite this 2.6-fold increase, the central bank's own calculations show it could still require roughly 43 years to fully exit its stock holdings, down from the previously estimated 112 years.
The BOJ's cautious approach reflects a fundamental constraint: the bank must find willing buyers for its accumulated equity positions without destabilizing the markets it spent years supporting. The acceleration, approved on October 30 and set to begin in January 2027, represents the bank's attempt to balance faster exits with market stability.
Origins of the Central Bank's Equity Holdings
The BOJ began purchasing exchange-traded funds in 2010 as part of its monetary easing program, aimed at encouraging investment in an economy facing weak demand and deflation. By acquiring ETFs rather than individual stocks, the bank gained broad stock market exposure while signaling support for equities. The strategy was designed to reduce the risk premiums investors demanded for holding equities, thereby encouraging broader investment activity.
The bank ended new ETF purchases in March 2024, but halting purchases left the existing investments on its balance sheet. Unlike bonds with maturity dates, ordinary equity ETFs have no set repayment date, forcing the BOJ to actively sell its holdings rather than simply waiting for them to mature.
Mechanics of the Accelerated Exit
At the new pace, the BOJ estimates its annual sales correspond to approximately ¥2.46 trillion at market value, representing about one-tenth of one percent of overall Tokyo Stock Exchange trading volume. The bank emphasizes that it will seek appropriate prices and aims to avoid both losses and market disruptions, retaining the option to adjust or suspend sales if conditions warrant.
The 43-year timeline is an arithmetic estimate based on dividing end-September 2026 holdings by the proposed constant annual sales pace. Officials have reported that sales since January 2026 have proceeded smoothly with no major market effects, contributing to the decision to accelerate the program.
By extending the disposal across decades, the BOJ allows buyers gradual opportunities to absorb the portfolio while maintaining flexibility to reassess execution if market conditions deteriorate. Future officials will inherit both the remaining assets and discretion over the sales pace.
