The Bank of Japan kept its policy rate unchanged at 1.25%, a 31-year high, by an 8-to-1 vote on Friday, while simultaneously announcing that it will raise the annual pace of selling its exchange-traded fund holdings from roughly 330 billion yen (book value) to about 860 billion yen, equal to approximately 0.1% of market turnover (previously about 0.05%), effective from January 2027.
At that pace, the time needed to fully unwind the holdings would shrink from an earlier estimate of about 112 years to roughly 43 years.
When the news broke, the Nikkei 225 was already under pressure from a global technology stock selloff, falling as much as 3% in morning trade and losing the 64,000 level, before paring losses to about 2% in the afternoon and closing down 2.44%.
Even so, the market delivered its first pricing of this "surprise sale" through prices: it can absorb it.
The rate decision itself: a boring hold, one unexpected acceleration
The rate decision held no suspense: an 8-to-1 vote to keep the rate at 1.25%, with hawkish board member Takata dissenting in favor of an immediate hike to 1.5%; not a single member called for a cut.
The BOJ has already raised rates twice this year, by 25 basis points each in June and September, a clearly shorter interval than the roughly once-every-six-months pace of 2024-2025.
The surprise lay in the ETFs.
The selling plan was finalized in September 2025 and launched in January 2026, and after a year the central bank assessed its operation as "smooth and without major market impact"; given the continued expansion of stock market turnover, the committee unanimously approved the acceleration and retained a flexible clause allowing temporary adjustments within the annual quota, or even a suspension of sales, should financial market conditions change.
Doing the math: the BOJ accumulated 37.19 trillion yen of ETF purchases in the 2010s to support the stock market (the total book value as of March 2024, when purchases stopped); the "43-year" unwind period is derived by dividing the end-September 2026 holdings by the annual sale amount (on a book-value basis), and is an estimate rather than a set maturity date.
Based on the market-to-book ratio of ETFs already sold since January 2026, the 860 billion yen book-value sale amount equates to roughly 2.46 trillion yen of market value per year.
With the bad news priced in, why did the Nikkei pare its losses
US technology stocks extended their decline overnight, as Alphabet's revenue miss reignited concerns over AI capital spending, and Asian markets followed suit, with chip testing equipment maker Advantest and SoftBank Group both falling more than 7%.
The Nikkei 225 came under pressure in the morning and fell as much as 3%, before narrowing to about 2% in the afternoon after the rate decision and ETF news.
The judgment of Aizawa Securities senior strategist Yukihiro Kawanishi represented the majority view: "It looks negative at first glance, but given current daily turnover, the market impact is limited. The central bank's holdings reduce the number of shares available for trading in the market, and the selling could actually improve liquidity in these individual stocks."
T&D Asset Management chief strategist Hiroshi Namioka pointed to another layer: "Almost no one expected the central bank to accelerate the selloff, so this is indeed a surprise. But the BOJ likely made the decision after assessing market conditions such as turnover, which in itself conveys to the market its confidence that the selling will not distort prices."
There were also cautious voices.
Fukuoka Financial Group chief strategist Hiroshi Namioka, a former BOJ official, argued that holding such a massive stock portfolio "is not healthy for a central bank," but that announcing it at such a fragile market moment was not ideal timing.
The reaction in the currency and bond markets leaned closer to a safe-haven logic than a supply shock: the yen rose to a high of 157.115 against the dollar, erasing most of its October decline, while the 10-year JGB yield plunged 5.5 basis points to 2.780%, its lowest close since August 6, with stocks falling and bonds rising.
"Nearly tripling the pace" sounds intimidating, but the 0.1% share of turnover is the essence: this is a gradual exit, not a balance-sheet shock, especially since the central bank retains the right to pause.
Second, the market's calm stems half from the expansion of turnover and half from the very fact that "the central bank dares to sell": it means policymakers believe the market is now large enough not to need the central bank's hand.
Realized gains could support Takaichi's fiscal plans
To understand this acceleration, one must return to the origins of the holdings.
In 2011, the BOJ established what the industry commonly calls the "1% rule": if the TOPIX fell 1% in morning trade, the central bank would enter in the afternoon to buy ETFs; it did so until March 2024, when it announced the end of purchases, having invested a cumulative 37.19 trillion yen.
Japanese stocks then rose for two straight years: the Nikkei gained 26% last year and about 25% so far this year, while the TOPIX rose about 16%, significantly inflating the market value of the holdings, leaving the central bank "sitting on considerable unrealized gains."
Economists pointed to the fiscal implications: most of the realized gains from the sales will be remitted to the national treasury, objectively lending support to Prime Minister Sanae Takaichi's ambitious fiscal plans, including a proposed cut to the food consumption tax (the BOJ's current projections do not yet factor in that effect).
In other words, the central bank's exit is no longer a one-way drain: with a nearly threefold gap between book value and market value, this is a "handover with gains."
Policy outlook: a declaration of victory, and a door left open for December
A signal more important than the ETFs is hidden in the outlook report.
For the first time, the BOJ formally confirmed that underlying inflation is "generally at a level consistent with the 2% price stability target," a declaration of victory in a 14-year battle for a central bank that has spent most of its time since gaining independence in 1998 fighting deflation; it also stressed that policy "has entered a new phase," with a rate hike every few months among the options going forward.
On forecasts: median real GDP growth of 0.7%, 0.7% and 0.8% for fiscal 2026-2028; core CPI of 2.4%, 2.7% and 2.3%, with fiscal 2026 revised down 0.1 percentage point from the July forecast and fiscal 2027 and 2028 revised up.
Tokyo's October core CPI, a leading indicator of nationwide prices, has already substantially exceeded 2%.
The oil price assumption is for Dubai crude to gradually fall from the current roughly $105 to about $70 by the end of the forecast horizon.
The market is preparing for December.
Economist surveys show all respondents expect the BOJ to pave the way for a rate hike in December or January, with 13 expecting the terminal rate for this cycle to reach 1.75%-2% by mid-2027.
State Street Investment Management chief fixed-income strategist Masahiko Loo summed it up: "A boring hold, a hawkish direction; the debate is no longer whether the BOJ will normalize, but where the terminal rate lands. Japan is joining the global synchronized tightening."
For now, what determines the short-term direction of Japanese stocks is not ETF supply, but the December rate hike and the trajectory of the AI trade; the real long-term tension lies in the bond market, where the central bank's shift from a massive buyer to a moderate seller, combined with the rate-hike cycle, is what the JGB market will have to digest slowly over the coming years.
