Tokyo, 22 September 2025 — The Bank of Japan (BOJ) has moved to reduce a massive overhang in the Japanese equity market by laying out a plan to gradually sell off its exchange-traded fund (ETF) holdings. The strategy, stretching over many decades, signals a shift in Japan’s monetary policy after years of ultra-loose stimulus.
During its recent policy meeting, the BOJ kept its short-term interest rate steady at 0.5%, as expected. But beyond confirming the status quo on rates, the central bank surprised markets by revealing plans to start selling ETFs annually at a pace of approximately ¥620 billion in market value — an amount equivalent to about ¥330 billion in book value. The proposed pace of real estate investment trusts (J-REITs) disposals was also included, though at a much smaller scale relative to the ETF holdings.
The BOJ’s ETF portfolio is massive. By mid-September, it had accumulated ETFs valued at around ¥75-¥79.5 trillion (roughly USD $500-$540 billion) over the years through its stimulus programs to fight deflation, promote investment, and support financial markets.
Stocks initially declined on the announcement, with the Nikkei and other equity indices feeling pressure from the idea of offloading so many assets. But much of the drop was later pared back as investors digested the gradual nature of the plan and its very slow pace. At ¥620 billion per year, it would take more than a century to fully unwind the BOJ’s ETF holdings at the proposed rate.
What This Means for the Market
The move is considered one of the clearest signs yet that BOJ is preparing to normalize policy after years of aggressive market intervention.
By selling ETFs rather than holding them indefinitely, BOJ is reducing its direct influence over stock valuations. That overhang — the possibility that the central bank might dump large volumes of stock in the market — had long hung over Japanese equities. Unwinding it gradually helps signal a return to more typical central bank behavior.
The plan also reinforces a more hawkish tone within the BOJ governing body. Two board members dissented during the rate-meeting, favoring a rate hike rather than holding rates steady, suggesting increasing internal pressure for tighter monetary policy once data supports it.
There are ripple effects beyond stocks. The yen strengthened following the announcement, as the plan to reduce policy stimulus lifted expectations for tighter financial conditions. Investors also saw potential gains for banks, which may benefit from better interest margins if the BOJ ends the era of near-zero yields.
Challenges and Watchpoints
While the plan is clearly laid out, the BOJ must walk a fine line. The slow disposal pace is intended to avoid destabilizing markets, but keeping that discipline will be key. Any misstep — disposing too quickly or without spillover planning — could unsettle equities, especially in certain sectors where BOJ holdings have been large and influential.
Another area to observe will be how inflation and wage growth evolve. Core inflation in Japan remains above target, but underlying inflation pressures are inconsistent. Policymakers are likely to use this data as justification for either maintaining this slow unwind or accelerating rate tightening.
The political context also adds complexity. Japan’s leadership race within the ruling party and public sensitivity to inflation or cost-of-living pressures mean that monetary policy shifts are rarely purely technical.
