A single remark that "inflation has reached target" boosted the yen, with the market betting that the Bank of Japan is just one step away from a December rate hike.

Notice that after the Bank of Japan kept its benchmark interest rate unchanged with an 8-to-1 vote, the yen largely held onto its gains. The BOJ also signaled that underlying inflation has reached the 2% target, opening the door to a December rate hike. Market focus now shifts to the press conference by BOJ Governor Kazuo Ueda at around 3:30 p.m. local time. In the BOJ's October 30 decision, the most unexpected element was not the interest rate but the acceleration of ETF sales. The central bank announced it would speed up the pace of ETF sales to about JPY860 billion (about US$5.5 billion) per year, a change that broke prior market expectations and prompted sharply contrasting interpretations. The BOJ's long-standing holding of a massive ETF portfolio is a signature legacy of its years of easy policy. The central bank had previously explicitly reassured the market that these holdings would be gradually sold over more than 100 years to avoid disrupting stock prices. That statement had long given investors peace of mind. Now, with the pace of sales accelerating, that reassurance is being withdrawn. But the market shows clear divergence over what this signal means. The "changes" and "non-changes" in the decision What remained unchanged was the interest rate itself; what changed were two key signals. First, the policy statement signaled that underlying inflation has reached around the 2% price stability target, pointing to further tightening; second, the pace of ETF sales suddenly accelerated from the reassuring arrangement of "selling over more than 100 years" to about JPY860 billion per year. The former is a substantive shift in monetary policy, and the latter is an acceleration of balance sheet normalization, together forming the hawkish undertone of this decision. Inflation "hitting target": paving the way for a December rate hike The senior macro strategist at Lombard Odier offered the most striking characterization: the statement that inflation has reached the policy target level is effectively a declaration that the reflation effort that began in 2012 and ran through the Abenomics era has succeeded. This "victory declaration," together with the assessment of upside price risks, has paved the way for resuming rate hikes in December this year. OCBC FX strategist Shen Maoxiong held a similar view. He believes the decision itself contained no surprise, but the hint that "the official inflation target has been achieved" foreshadows further policy tightening in the future, which should be positive for the yen. Strategist at a Hong Kong bank Shogo Karitani was relatively neutral, noting that the wording on inflation in the statement was basically in line with expectations and that the BOJ was merely indicating that underlying inflation has reached around the 2% price stability target. Faster ETF sales: a debate over signals ETF sales were the most unexpected part of this decision, and market interpretations diverged. Shogo Karitani took the hawkish side: the acceleration of ETF sales is "unexpected," another step toward monetary policy normalization, and should be regarded as a hawkish signal, and it has already triggered some modest yen buying. He added, however, that for the FX market, ETF sales are essentially more a stock market issue. Shinkin Asset Management strategist Kazuki Sawamura offered a more complex set of judgments. On the one hand, he worried that the previous stance of "selling over more than 100 years" had reassured investors, and that after the acceleration, investors may form the expectation that "if stock prices rise further, sales will be faster," and this self-reinforcing feedback could suppress market upside over the long term. On the other hand, he coolly calculated that the scale of sales is about JPY10 billion per day, while average daily turnover on the Tokyo Stock Exchange Prime Market is about JPY10 trillion, meaning the sales amount to only about 0.1%, so the actual supply-demand impact is limited. Yen outlook: anchored range and external disturbances On the yen's prospects, Homin Lee was the most explicit. He expects Kazuo Ueda to express a more clearly hawkish inclination at the afternoon press conference to anchor market expectations for the December policy meeting and reduce unnecessary complications relative to FX intervention. He believes the BOJ's envisioned quarterly rate hikes should be enough to anchor the yen against the dollar in the 155-160 range, especially as upside room for USD/JPY is constrained by the threat of credible market intervention. Shen Maoxiong flagged disturbances from external variables: oil prices are complicating the near-term outlook for USD/JPY, and the risk of renewed escalation of the U.S.-Iran conflict after the U.S. midterm elections has pushed oil prices higher, potentially preventing USD/JPY from fully benefiting from the backdrop of dollar weakness caused by AI concerns. Shogo Karitani brought the focus back to the immediate issue: ETF sales are mainly a stock market issue, and for the FX market, attention should shift to Governor Ueda's press conference for clues on the future direction of monetary policy.
