The Bank of Japan announced it will begin selling exchange-traded funds in January 2027 at an annual pace of approximately 860 billion yen, stretching the divestment over roughly 43 years.
The move marks the BOJ's first concrete timeline for normalizing a balance sheet bloated by decades of unconventional monetary policy. The extended runway reflects the central bank's determination to avoid triggering the sharp duration shock that plagued other major economies during faster quantitative tightening cycles.
From a bond market perspective, the divestment removes a structural buyer of Japanese equities but poses minimal duration risk to government bonds given the glacial pace. The BOJ accumulated vast ETF holdings as part of its asset purchase program designed to suppress risk premiums and channel capital into equity markets to combat deflation.
Japan's 10-year yield has remained anchored by the BOJ's yield curve control regime, which has effectively capped long-term rates. The gradual sale schedule suggests the central bank will maintain this policy constraint even as it withdraws from ETF purchases, preventing the kind of curve steepening that would typically accompany central bank divestment elsewhere.
The announcement provides domestic institutional investors—particularly life insurers and pension funds managing long-duration liabilities—clarity on the trajectory of BOJ participation in equity markets. Over four decades, the reallocation of 860 billion yen annually represents a slow erosion of the central bank's role as a marginal buyer of risk assets, not an abrupt withdrawal.
