Bank of Japan November Rate Hike Speculation Surges: Reading the Impact on the Yen and the JGB Market

Lead

At its October 22 policy meeting, the Bank of Japan held its policy rate steady at 0.75%, but the statement quietly added the phrase "we are in the process of confirming a virtuous cycle of wages and prices." The following day, October 23, the 10-year JGB yield rose to 1.22%, and the probability of a 25bp additional rate hike at the November meeting briefly exceeded 60% in the OIS market. More important than the short-term price action is the fact that the BOJ's "reaction function" appears to be changing—subtly but surely.

What Is Happening

What the market focused on in the October 22 statement was a subtle shift in the language surrounding the inflation outlook. Tokyo's September CPI (released by the Ministry of Internal Affairs and Communications on October 20) came in at 2.4% year-on-year, with core-core CPI—excluding fresh food and energy—at 2.1%, both running above the BOJ's target.

On X, the following reactions spread in response to Governor Ueda's remarks:

"The 10-year yield has broken above 1.2%. I want to act before the next meeting's rate hike is fully priced in." (Market participant, over 20,000 followers)

JGB futures declined after the meeting, and economists at financial institutions began upgrading a November rate hike to their base-case scenario.

Background

The BOJ ended its negative interest rate policy in March 2024, and has since pursued a gradual normalization path: 0.25% in July 2024, 0.5% in January 2025, and 0.75% in October of the same year. Over this period, real wages (Ministry of Health, Labour and Welfare, Monthly Labour Survey) turned positive from April 2025 onward, and as of August 2026 were continuing to rise modestly at +0.8% year-on-year.

What matters here is not the level of interest rates per se, but confirmation of the sustainability of whether nominal wage growth can continue to outpace inflation. The Cabinet Office's October Economy Watchers Survey showed the leading index at 49.8—on the verge of falling below neutral—leaving questions about the resilience of consumer spending.

Meanwhile, Reuters has reported that the Federal Reserve is considering an additional 0.25% rate cut at the November FOMC meeting (November 4–5), quietly building yen-strengthening pressure through the scenario of a narrowing U.S.-Japan interest rate differential.

Key Points to Watch

What the Statement's "Wording Shift" Signals

Comparing the September statement with the October statement, the language moved one step forward—from "we will continue to confirm a virtuous cycle of wages and prices" to "we are in the process of confirming" it. Based on five years of experience covering the BOJ as a beat reporter, this kind of shift to the present progressive tense can be read as groundwork for the next action. Miss the change between the lines, and your judgment will fall behind the curve.

Measuring the Significance of the 1.2% Long-Term Yield Accurately

This should be considered separately from concerns about expanding unrealized losses on the BOJ's JGB holdings. The 1.2% level is close to its highest since before the launch of quantitative and qualitative easing in 2013. The prevailing view is that meaningful impacts on corporate capital investment costs and household mortgage burdens will not materialize until the yield exceeds 1.5%, which means the current level is still "just short of the warning zone."

The Structural Challenge Signaled by the Yen at 145

The prior day's closing rate (October 19) was ¥145.3 per dollar. While the yen has strengthened by more than 15 yen from the 160-yen range in mid-2025, it remains substantially below the IMF's estimated purchasing power parity (approximately ¥105). In the short term, the yen is driven by the U.S.-Japan rate differential; in the medium term, by inflation differentials; and in the long term, by the structure of the current account balance. Reversing the structural trend of yen weakness will require a considerable time horizon.

Reading the Link to Corporate Earnings

As mid-year earnings for March fiscal-year companies kick into full gear this week, the assumed exchange rates used by export-oriented firms that have benefited from the weak yen will be a key focal point. Many companies set their assumptions in the ¥145–150 range, making the current level an upside factor. However, how analysts assess the risk of yen appreciation heading into the second half of the fiscal year will be the deciding factor in whether earnings forecasts are revised.

Editorial Perspective

Drawing on experience submitting long-term JGB yield forecasts to the IMF during my think tank days, the current phase represents the tail end of the "first stage of normalization." A hike from 0.75% to the next level of 1.0% is technically a modest 25 basis points, but its psychological impact as a milestone on markets will be far greater than the number suggests.

From the feel of having closely covered BOJ meetings as a beat reporter, the Ueda leadership tends to move slightly ahead of the data rather than chasing it, in order to avoid being judged as having "fallen behind." The pattern of "holding in October, then moving in November"—acting after a brief pause—is a method that has been repeated in past rate-hike cycles.

The medium-term variable to watch is the sustainability of wage growth. This year's spring wage negotiations saw nominal wage growth at major manufacturing firms reach 3.8% for the second consecutive year at a high level (Ministry of Health, Labour and Welfare). Whether that momentum is spreading to small and medium-sized enterprises and the service sector will be the essential variable determining monetary policy from next spring onward.

From a long-term perspective, Japan's full transition to a "world with interest rates" is still some way off. With fiscal discussions ongoing toward achieving a primary balance surplus in fiscal year 2027, the BOJ is not in a position to rush normalization on its own.

Summary

Speculation about an additional BOJ rate hike will act on markets in the short term through upward pressure on the yen and interest rates. But what is structurally important is how confident the BOJ can become in its judgment that a virtuous cycle of wages and prices has been "confirmed." Rather than the outcome of the November meeting itself, what deserves attention is the language in the subsequent statement—specifically any wording that hints at the next move. In Japan's economy today, a rate hike is not the "goal" but merely one episode in the "process of normalization."
