Tokyo’s inflation is heating up, but the BOJ may not be in a hurry to hike again in October

• Inflation pressures remain elevated: Producer-price inflation eased to 6.8% YoY in September, but rising input costs continue to filter through to consumer goods and services, keeping inflation risks alive.
  
  
• Tokyo's inflation spike may overstate underlying pressures: Core CPI accelerated to 2.7% YoY in September, partly driven by temporary policy-related factors, although broader goods and services price pressures remain persistent.
  
  
• An October BOJ rate hike appears unlikely: With producer-price inflation easing and temporary factors exaggerating Tokyo's CPI rebound, underlying inflation has yet to exceed BOJ's 2.8% forecast. A potential Fed pause also gives the BOJ greater room to hold rates in October while maintaining its longer-term tightening bias.
  
  
• Higher rates create opportunities and risks for Japanese equities: We favour financials and companies with strong pricing power, while remaining selective towards real estate businesses and exporters vulnerable to yen appreciation.
  
  
• Our recommended Japan ETF remains the Xtrackers Nikkei 225 UCITS ETF 1D (LSE: XDJP), which offers a low expense ratio of just 0.09% annually.

Japan's producer-price inflation remains elevated, while Tokyo's consumer inflation accelerated sharply in September, raising fresh questions about the Bank of Japan's (BOJ) next move. Having raised interest rates to 1.25% in September, their highest level in 31 years, the BOJ now faces another crucial decision at its 29–30 October meeting: should it tighten further to contain persistent inflation, or pause to assess the impact of its recent rate hike?

We unpack Japan's latest inflation data, what they mean for the BOJ's upcoming decision and the implications for Japanese equities.

Producer-price inflation eased slightly, but underlying cost pressures remain elevated

Japan's producer-price inflation moderated to 6.8% year-on-year (YoY) in September, down from 7.6% in August and its recent peak of 7.7% in July. While this marks the second consecutive month of easing, the third-quarter average of approximately 7.3% remains the highest since the 2022–2023 import-price shock. The latest figures therefore point to a moderation in the pace of price increases rather than a meaningful easing of cost pressures.

Much of this inflation remains concentrated in commodity-intensive industries. On a contract-currency basis, import prices for petroleum, coal and natural gas surged 26.1% YoY in September, while metal prices increased 25.2%. These figures highlight the continued impact of elevated global commodity prices, particularly against the backdrop of prolonged geopolitical tensions in the Middle East. As a result, metals, energy and petrochemicals account for roughly two-thirds of the annual increase in producer prices in September, with rising input costs feeding into downstream products such as plastics, chemicals and utilities (Table 1).

Table 1: September PPI vs August readings

Measure	Sept 2026	Aug 2026
Producer Price Index (PPI)	6.8%	7.6%
Petroleum and coal products	11.5%	14.7%
Chemicals and related products	13.3%	13.0%
Electric power, gas and water	10.5%	8.2%
Plastic products	12.8%	11.3%
Electrical machinery and equipment	5.1%	4.9%
Nonferrous metals	40.2%	43.3%
Iron and steel	3.2%	2.7%

The divergence between import and domestic producer prices is especially noteworthy. Yen-denominated import prices increased 24.5% YoY, exceeding the 6.8% rise in producer prices by 17.7 percentage points (Figure 1). Although this gap appears to have peaked in June, it remains substantial.  This suggests that Japanese manufacturers have not fully transmitted higher import costs into domestic selling prices. Even as headline producer-price growth begins to ease, Japan’s inflation pipeline remains under pressure.

Tokyo inflation jumped in September, but temporary factors distort the picture

The impact of rising production costs is becoming increasingly visible in consumer prices. Ahead of Japan's nationwide September CPI release on 23 October, Tokyo's inflation figures, a closely watched early indicator of national price trends, showed a sharp acceleration. Headline inflation accelerated from 1.9% to 2.7% YoY in September, while core inflation, which excludes fresh food, jumped from 1.8% to 2.7%, exceeding market expectations of 2.4%. The more closely watched core-core measure, excluding both fresh food and energy, also surged from 2.0% to 3.0%.

These figures suggest a renewed inflationary surge. However, a closer examination reveals a more nuanced picture: temporary policy-related distortions exaggerated September's inflation strength, even as underlying price pressures continued to broaden.

1. Policy-related distortions explain part of September's inflation spike

Some of the sharpest increases came from changes in municipal support measures. Tokyo traditionally waives basic water charges for four summer months. However, the subsidy period was brought forward by one month in 2026, running from May to August, compared with June to September in 2025. This shift resulted in an unusually large year-on-year comparison when charges resumed, with water prices surging 65.6% in September. A similar distortion arose from Tokyo's childcare subsidies, introduced in September 2025. The anniversary of their implementation removed part of the favourable year-on-year comparison that had supported August's reading.

As these measures are specific to Tokyo, their impact on nationwide inflation should be considerably smaller, suggesting that the national September CPI release may paint a less dramatic picture than Tokyo's figures imply.

2. Consumer goods are showing clearer signs of cost pass-through

Nevertheless, dismissing September's inflation rebound entirely as a statistical distortion would be a mistake.

Underlying price pressures are becoming more widespread across consumer goods. Household consumables inflation accelerated from 9.4% to 10.6% YoY, while household durables inflation rose sharply from 2.2% to 5.9%. These increases are consistent with the substantial rise in upstream production costs. Producer prices for chemicals (+13.3%), plastic products (+12.8%), and pulp and paper (+6.6%) have risen considerably, affecting the production and packaging costs of everyday items such as detergents, household products and toilet paper.

This is arguably more important than the temporary jump in water charges, because it raises the possibility that goods inflation could remain elevated even after September's policy-related distortions fade.

3. Services inflation is strengthening, adding another layer of persistence

Services inflation also accelerated, rising from 1.4% to 2.3% YoY in September. Part of the increase reflects the childcare-related base effect, while seasonal factors also contributed. Accommodation prices increased 4.6%, supported by travel demand around Japan's September “Silver Week” holiday period.

Nevertheless, the broader acceleration in services inflation warrants closer attention. Unlike goods inflation, which is heavily influenced by global energy and raw material prices and geopolitical developments, services inflation is more closely tied to domestic wages and labour costs, making it potentially more persistent. Japan's annual Shunto wage negotiations have delivered pay increases of more than 5% for three consecutive years, while persistent labour shortages continue to push up employment costs. As businesses increasingly pass these higher costs on to consumers, services inflation could become a more sustained source of price pressure, reinforcing the wage-price cycle that the BOJ has been seeking to establish.

Taken together, September's Tokyo CPI figures send two messages. Headline inflation likely overstates the immediate strength of underlying price pressures, but the broader trend towards higher consumer goods and services prices remains intact.

Expiring energy subsidies could reignite inflation pressures

Looking ahead, inflation faces an additional upside risk as Japan's summer electricity and city-gas subsidy programme, covering July through September 2026 usage, comes to an end.

The withdrawal of this support is expected to produce a noticeable increase in household utility bills. Standard electricity bills could rise by approximately JPY835–1,578 for October usage, depending on the provider. For example, TEPCO's standard monthly electricity bill is expected to increase by JPY1,286 to JPY9,561, or around 16%, while Tokyo Gas bills could rise by JPY744 to JPY6,488, equivalent to approximately 13%.

As October electricity and gas usage is generally reflected in the following month's bills, the impact could become more visible in November's inflation data. This means that even as September's temporary water-charge effect fades, the withdrawal of energy subsidies could introduce a fresh source of inflationary pressure heading towards year-end.

Combined with continued input-cost pass-through and firmer services inflation, it reinforces our view that Japan's inflation outlook remains elevated, despite the recent moderation in producer-price growth.

Why we believe an October BOJ rate hike remains less likely

Despite September's stronger-than-expected Tokyo inflation, we do not expect the BOJ to raise rates at its 29–30 October meeting. While inflation pressures support further monetary normalisation, we see little urgency for another hike so soon after September's tightening, for two key reasons.

1. Inflation is elevated, but the urgency to tighten has not increased materially

While producer-price inflation remains elevated, it has moderated for two consecutive months. Meanwhile, Tokyo's September CPI surge was partly driven by temporary policy-related factors rather than a sharp acceleration in underlying demand.

At the national level, we expect core inflation to remain broadly in line with the BOJ's previous forecast of 2.8% for fiscal 2026, with limited evidence of significant upside surprises. Policymakers can therefore afford to assess upcoming inflation readings, particularly the impact of expiring energy subsidies and normalising water charges, before tightening further.

Moreover, having just raised rates by 25 basis points to 1.25% in September, the BOJ has good reason to assess the impact on borrowing costs, business investment and household consumption before delivering another hike.

2. A potential Fed pause reduces immediate pressure on the yen

Developments in the US also support a patient approach. Fed officials, including New York Fed President John Williams, have signalled little urgency to raise rates again in October, while September's meeting minutes suggested limited appetite for aggressive tightening.

Mixed US economic data also support a cautious Fed. September's non-farm payrolls rose by just 29,000, well below expectations of 90,000, while July and August figures were revised down by a combined 60,000. However, core inflation accelerated from 2.4% to 2.6% YoY, presenting the Fed with a difficult trade-off between containing inflation and preventing further labour-market weakness.

We therefore expect the Fed to pause in October while maintaining a tightening bias. With inflation partly driven by energy-related supply shocks, another immediate hike could further weaken employment without meaningfully addressing the underlying price pressures. For Japan, a Fed pause would reduce the risk of a widening US–Japan interest-rate differential, easing downward pressure on the yen and giving the BOJ greater flexibility to hold rates in October.

Investment implications: Position for higher rates, but focus on earnings resilience

Japan's transition away from ultra-low interest rates is reshaping its investment landscape. Higher borrowing costs will increasingly differentiate companies by their pricing power, balance-sheet strength and earnings resilience. Nevertheless, corporate-governance reforms, improving capital efficiency and AI-related investment remain supportive of Japanese equities. We therefore remain constructive on Japan, but believe sector and stock selection will become increasingly important.

Financials remain the clearest beneficiary

We maintain our positive view on Japan’s financial sector. Further monetary-policy normalisation should support net interest margins for banks, while higher Japanese government bond yields can improve investment returns and spreads for insurers. With Japanese financial institutions also benefiting from structural corporate-governance reforms and increased shareholder returns, the combination of higher rates and stronger capital distributions provides a supportive backdrop. Financials therefore remain one of the most direct beneficiaries of the BOJ’s tightening cycle.

For investors looking to capture this theme, we recommend the Amova Japan Dividend Equity SGD, which provides exposure to Japanese companies with an emphasis on dividend income.

Be more selective with interest rate sensitive sectors

Conversely, higher borrowing costs pose challenges for J-REITs, property developers and highly leveraged companies, particularly those facing significant refinancing needs.

We remain constructive on selected Japanese small- and mid-cap equities, supported by domestic demand and corporate-governance reforms. However, rising financing and input costs reinforce the importance of pricing power, healthy balance sheets and strong cash generation.

We recommend the BNP Paribas Japan Small Cap Classic Cap SGD, which offers exposure to domestic growth opportunities and niche semiconductor supply-chain specialists. These companies’ specialised capabilities and competitive advantages can support pricing power, helping them navigate higher costs while benefiting from structural technology investment.

A stronger yen could create winners and losers among exporters

While the yen may remain rangebound in the near term amid global policy uncertainty, we expect further BOJ tightening to provide longer-term support for the currency. A stronger yen could weigh on exporters' overseas earnings and competitiveness, but the impact will vary significantly across industries.

Automakers appear more vulnerable, as recent earnings have benefited considerably from favourable currency movements despite relatively modest shipment-volume growth. In contrast, semiconductor equipment manufacturers are better positioned, with growth driven by AI investment and semiconductor capacity expansion rather than currency tailwinds alone.

For broad exposure to Japanese large caps, including technology and semiconductor-related opportunities, we recommend the Xtrackers Nikkei 225 UCITS ETF 1D (LSE: XDJP), which offers a low expense ratio of just 0.09% annually.

Alternatively, Singapore investors seeking local trading hours, SGD-denominated trading and a lower investment entry point can consider the iFAST Xtrackers Nikkei 225 UCITS Index ETF (SGX: JPY), scheduled to list on 22 October 2026. With an initial issue price of SGD 1 and a minimum trading lot of one share, it offers a more accessible way to invest in Japanese equities.
