BOJ Poised to Raise Rates in Q4: What It Means for Japan and the World

The wind is changing in Tokyo. After years of ultra-loose monetary policy, deflationary pressures, and ultra-low interest rates, signs are mounting that the Bank of Japan (BOJ) is getting ready to shift course—again. A Reuters poll from early September 2025 found that a strong majority of economists expect the BOJ to raise its key interest rate by at least 25 basis points (bps) in Q4 2025, raising the policy rate from 0.50% to around 0.75%.

This would mark another step in a long and delicate path back to what might be called ‘normal’ monetary policy for Japan. In this post, we explore the data and drivers behind this expected move, the implications for Japan, the global economy, and the risks the BOJ will need to manage.

Why the BOJ Is Likely to Hike

Several converging forces are pushing the BOJ toward tightening.

1. Inflation and Price Pressures

• Wholesale/Producer Inflation: Japan’s Corporate Goods Price Index (CGPI), which captures wholesale inflation, rose to 2.7% year-on-year in August, up from 2.5% in July. Food and beverage prices were a major contributor.

• Core inflation (consumer prices excluding volatile items like fresh food) has been above the BOJ’s 2% target for some time. Underlying inflation metrics—trimmed means, median measures—show persistent pressure.

• Rising food and utility prices have been pushing up inflation. Even where utility costs have been dampened temporarily by subsidies, overall inflation remains sticky.

2. Wage Growth & Labor Market Tightness

• Governor Kazuo Ueda has emphasized that wage increases are spreading beyond large firms into small and medium-sized enterprises (SMEs), a sign that inflation might be sustained.

• Labor shortages—partially due to demographic trends—are increasingly constraining supply, pushing companies to raise wages and pass on costs.

• The BOJ projects scheduled cash earnings for full-time employees to continue rising, though there is some concern about part-time and non-scheduled earnings under pressure.

3. Inflation Outlook & BOJ’s Projections

• The BOJ’s “Outlook for Economic Activity and Prices” report projects consumer price inflation (excluding fresh food) in the range of 2.5–3.0% for fiscal 2025. It expects inflation to ease to around 1.5–2.0% in FY2026, and hover near 2% in FY2027.

• Key point: while inflation may moderate, the BOJ expects underlying inflation pressures—wages, price-setting behavior—to remain, especially given labor market tightness.

4. External and Currency Pressures

• Yen depreciation: A weak yen tends to increase the cost of imports (fuel, food, energy), which contributes to inflation. The BOJ watches this carefully.

• Global headwinds: Tariff disruptions, supply-chain issues, energy prices, and trade tensions remain uncertain but capable of feeding inflation, disrupting exports, or both.

5. Political Dynamics

• Prime Minister Shigeru Ishiba’s resignation has introduced political uncertainty. The new leadership could have different attitudes toward fiscal policy, which may in turn affect the BOJ’s room to maneuver.

• Some leadership contenders from the ruling Liberal Democratic Party (LDP) support gradual normalization of monetary policy. Toshimitsu Motegi, for example, has publicly endorsed the BOJ’s plan to normalize policy.

What the Reuters Poll Says

The Reuters poll from September 2–9, 2025 highlights several expectations from economists:

• A large majority expect a rate hike in Q4 2025, of at least 25 bps.

• Even though many expect the U.S. Federal Reserve to cut rates, 93% of respondents said that would not deter the BOJ from tightening.

• About 55% of economists believe the key BOJ rate will rise to at least 0.75% by end-Q4.

• Most expect no change at the September 18–19 meeting, but that October or later in Q4 is more likely for hiking.

What It Means for Japan

Raising interest rates affects many parts of the economy—some with benefits, others with risks. Here are what to expect if the BOJ follows through.

A. Stronger Yen

• A rate hike tends to support the currency. If Japan raises rates while other major central banks are steady or easing, the yield differential makes the yen more attractive.

• A stronger yen helps reduce the cost of imports, easing inflation on imported goods, which is especially important given recent import-driven inflation.

B. Inflation Control vs. Cost of Borrowing

• Higher rates can help temper inflation by making borrowing more expensive, cooling consumption and investment.

• But Japan’s economy is already growing slowly. Too sharp or rapid a hike could drag on growth—especially in consumer sectors, real estate, and sectors sensitive to interest costs.

C. Real Growth & Corporate Profits

• Japan is export-oriented. A stronger yen may erode competitiveness abroad, reducing profit margins for exporters.

• Domestic firms may face rising input costs. Passing those costs to consumers depends on demand elasticity, competition, and wage trends.

D. Financial Markets & Government Bonds

• Japanese Government Bonds (JGBs): higher interest rates mean higher yields. That may make JGBs more attractive to foreign investors, but also raises the government’s interest servicing burden (Japan is heavily indebted).

• Asset markets could feel pressure (e.g. real estate, equities) if borrowing costs bite.

E. Wage-Price Spiral Risk

• Wage increases are already underway. If wages keep rising and firms keep passing on cost increases, inflation expectations may take hold, which in turn can make inflation more persistent.

• The BOJ has stressed that controlling expectations (of inflation) is as important as current inflation metrics.

Global and Regional Implications

Japan’s moves won’t happen in a vacuum. Given its size and interconnectedness, what BOJ does (or doesn’t) will ripple globally.

1. Currency & Capital Flows

• Yield differentials between Japan and countries like the U.S., Europe, or emerging markets could shift capital flows. Investors might favor Japanese assets if rates elsewhere are declining.

• Yen appreciation could alter trade balances not just for Japan but for trading partners, possibly reducing Japan’s exports and affecting countries that export to Japan.

2. Global Inflation & Trade

• Japanese demand: if Japan slows because higher rates dampen consumption or investment, that could reduce demand for imports, affecting exporters globally.

• Trade policy and tariffs are already causing supply chain stress; currency shifts could amplify or offset those pressures.

3. Fixed Income & Bond Markets

• BOJ action could set benchmarks for global bond markets, especially in Asia. If Japanese rates rise, longer-term yields globally may shift too.

• If inflation expectations become sticky globally, central banks elsewhere will need to consider more aggressive tightening or risk losing credibility.

4. Emerging Markets

• Many emerging economies have borrowed in foreign currencies or are sensitive to global funding conditions. Higher rates in one major economy (and the prospect of yield differentials) can tighten conditions for emerging markets, possibly causing capital outflows or currency depreciation.

Risks and Uncertainties

While many signs point toward a rate hike, there are several risks the BOJ must manage. Mis‐steps or shocks could make the path bumpy.

Political Uncertainty

• The resignation of PM Ishiba, a leadership contest in the LDP, and potential changes in government stance (especially toward fiscal policy) complicate the BOJ’s calculations.

• Some LDP leaders are more dovish, favoring fiscal stimulus over tightening. If a leader less supportive of rate hikes comes in, there may be political pushback.

Mixed Economic Data

• Some parts of Japan’s economy remain fragile, especially sectors dependent on global demand or exports. Weakness in those may counteract inflationary pressures.

• Consumer sentiment remains under pressure from price rises; real disposable income might lag, squeezing household demand.

External Shocks

• Global trade tensions, tariffs, supply disruptions (e.g. food, energy) could destabilize projections.

• Oil, commodity prices: if energy prices spike due to geopolitical tensions, inflation could overshoot expectations. Conversely, if prices collapse, inflation risks may ease.

Currency Movements

• Yen appreciation helps dampen import inflation, but too much strengthening could undermine exports. BOJ must balance exchange rate effects.

Inflation Expectations & Wage Dynamics

• Inflation expectations are still not deeply anchored above target. If inflation expectations drift too low or volatile, BOJ’s inflation target credibility could be questioned.

• Wage growth outside large firms is improving, but there is uncertainty about whether all firms will be able to raise wages sustainably, especially given global cost pressures.

What to Watch Next

To understand whether the expected rate hike will happen, and how big it will be, keep an eye on:

1. BOJ Policy Meetings — Especially the one on September 18–19, 2025. While the consensus is that nothing will change then, clues in the minutes, summary of opinions, and expressions by BOJ officials will matter.

2. Tankans (Business sentiment surveys), trade data, industrial production — seeing whether exporters are suffering, whether demand is holding up.

3. Wage reports & labor market statistics — Are wages rising widely or only in certain sectors? Is the labor shortage effect intensifying?

4. Inflation decomposition — How much of inflation is from food, energy, imported components vs. domestic services, wages?

5. Import price trends and yen movements — A strong yen could ease some inflation pressure; a weak yen could exacerbate import costs.

6. Political developments — The LDP leadership vote (October 4, 2025) and what the new government signals about fiscal discipline and coordination with BOJ priorities.

Narrative: Why This Moment Is Significant

For many years, the BOJ has been a central bank of quiet patience. Deflation, low growth, tepid inflation expectations—all of these made it hard for any tightening to stick. Even small rate increases or policy rollbacks raised fears that Japan could slip back into stagnation.

But that environment appears to be shifting:

• Inflation has not just crossed the 2% benchmark; it has persisted and broadened.

• Wages are rising in more places than just big firms, labor shortages are forcing behavior changes.

• The BOJ has already ended negative interest rates and yield-curve control (YCC), unwound some ultra-easy tools, and is now looking at shrinking part of its balance sheet (including large holdings of exchange‐traded funds, or ETFs).

This isn’t merely about raising rates. It’s about Japan trying to recalibrate its economic equilibrium—to live with inflation around the BOJ’s target, to ensure wages and productivity move in tandem, and to avoid repeating past periods where monetary policy tools were exhausted.

If the BOJ Hikes: Scenarios & Impacts

Below are scenarios for how things might play out, from moderate to more aggressive, and what each would mean.

How the World Might Read This Move

From the vantage of foreign investors, central bankers, and trade counterparts, Japan’s expected tightening will send signals that reach far beyond Tokyo.

• Investors will be watching for Japanese assets becoming more attractive, especially in fixed income. JGBs may offer higher real yields, but risk premiums (currency, sovereign) will matter.

• Other central banks will see this as further confirmation that inflation remains global, not a transitory phenomenon. It increases pressure on cautious central banks in Asia, or small open economies, to maintain credible paths.

• Exporters to Japan may find demand softening; importers may face difficulties with yen volatility.

• Multilateral institutions and policy analysts will look at Japan as a test case: can a mature economy exit decades of very easy money without breaking something important—e.g., growth, consumer confidence, financial stability?

---

Potential Challenges for the BOJ

To navigate this path safely, the BOJ will need to manage:

• Communication carefully — rate markets expect clarity; miscommunication can lead to volatility in the yen or bond markets.

• Balancing growth vs inflation — Japan’s economy is not robustly fast; over-tightening could trigger a slowdown.

• Coordination with fiscal policy — if the government is seen running large deficits (or pressuring BOJ), that could reduce the effectiveness of monetary tightening.

• Housing and property market — in Japan, with a lot of household debt and sensitivity to borrowing costs, real estate could suffer.

Conclusion

The BOJ’s expected rate hike in Q4 2025 may not be earth-shaking in magnitude—but it is deeply symbolic. It represents Japan moving more fully toward a post-deflation, post-zero-rate world. The choice between acting now or waiting is not just about timing; it’s about anchoring expectations, preserving credibility, and ensuring that inflation does not become a dampening burden on households and firms.

Globally, this shift has consequences: for currency markets, for yield curves, for trade flows, and for the psychology of economic management. For Japan, success means raising rates without breaking growth, maintaining export competitiveness, and managing inflation expectations so that they do not swing wildly either way.

We’ll be watching the BOJ’s September meeting for signals, the October-December window for action—and the broader story will continue in how wages evolve, how consumers respond, how global risks (trade, energy, geopolitical) develop.
